The systematic combination of well-defined coordination spheres and multiple types of ligands (heteroleptic) can lead to the generation of hierarchical metallosupramolecules with a high level of complexity and functionality. In particular, a specific multilevel coordination-driven assembly through the initiate generation of multinuclear clusters can form unique heteroleptic multiple-stranded supramolecular complexes. Herein, we report novel triple-stranded nickel-based supramolecules constructed from two different ditopic ligands ([1,1':3',1''-terphenyl]-4,4''-dicarboxylate (TP) and 2,6-pyridinedicarboxylate (PDA)) and a nickel precursor. The solid-state structures of the as-synthesized supramolecules revealed that three PDA ligands are employed to fabricate a tetranuclear ({Ni

Objective : To perform a comparative analysis of therapeutic effects associated with two different shapes of ceria nanoparticles, ceria nanorods (Ceria NRs) and ceria nanospheres (Ceria NSs), in an in vitro model of traumatic brain injury (TBI).Methods : In vitro TBI was induced using six-well confluent plates by manually scratching with a sterile pipette tip in a 6×6-square grid. The cells were then incubated and classified into cells with scratch injury without nanoparticles and cells with scratch injury, which were treated separately with 1.16 mM of Ceria NSs and Ceria NRs. Antioxidant activities and anti-inflammatory effects were analyzed.Results : Ceria NRs and Ceria NSs significantly reduced the level of reactive oxygen species compared with the control group of SH-SY5Y cells treated with Dulbecco’s phosphate-buffered saline. The mRNA expression of superoxide dismutases was also reduced in nanoparticle-treated SH-SY5Y cells, but apparently the degree of mRNA expression decrease was not dependent on the nanoparticle shape. Exposure to ceria nanoparticles also decreased the cyclooxygenase-2 expression, especially prominent in Ceria NR-treated group than that in Ceria NS-treated group.Conclusion : Ceria nanoparticles exhibit antioxidant and anti-inflammatory effects in TBI models in vitro. Ceria NRs had better antiinflammatory effect than Ceria NSs, but showed similar antioxidant activity.

The fabrication of hollow mesoporous nanosilica with well-defined structural features for optimizing the integration of functional components is a challenge. Herein, we report a facile preparation of hollow fibrous nanosilica (HFNS) with high specific surface area (666 m

Co-based MOFs are directly grown using an electrodeposited layer of Co(OH)2 on carbon paper and converted to cobalt sulfide (CoxSy) through a post-treatment process. The final electrode system exhibits remarkable oxygen evolution reaction performance.

The assembly of functional nanoparticles within materials with unique architectures can improve the interfacial surfaces, defects, and active sites, which are key factors for the designing novel nanocatalysts. Nano metal–organic framework (NMOF) can be employed to fabricate nanodots-confined nanohybrids for use in electrocatalytic processes. Herein, we report a controlled synthesis of gold nanodot assembly within cobalt chalcogenide nanoshell (dots-in-shell Au/CoxSy nanohybrids). A cobalt-based NMOF (the cobalt-based zeolite imidazole framework, ZIF-67) is used as a versatile sacrificial template to yield dots-in-shell Au/CoxSy nanohybrids. Due to the synergistic effect of the well-dispersed Au nanodots and the thin CoxSy nanoshell, the obtained dots-in-shell Au/CoxSy nanohybrids exhibit enhanced performance for the oxygen evolution reaction (OER) with low overpotential values at a current density of 10 mA cm−2 and a small Tafel slope (343 mV and 62 mV dec−1, respectively).

For the composting aeration, positive aeration (PA, blow type) is commonly used but suffers from the problem of odor diffusion, while negative aeration (NA, suction type) is scarcely used but it can minimize odor. However, the effect of aeration type on the organic matter degradation rate in large-scale composting is still unknown. In this study, we investigated the effect of aeration type on the organic matter degradation and the dynamics of the microbial community and catabolic function during composting using 200 L cylindrical drum reactors under self-heating condition. The organic matter degradation of Run PA was faster as compared to that of Run NA. This could be attributed to the higher heat retention in Run PA. The microbial community involved in the degradation of easily degradable material was found to be similar in both runs, despite different temperature profile and organic matter degradation rate. The key functional genes predicted by PICRUSt showed that the gene abundance of protease was similar in Run PA and Run NA, indicating that the high temperatures associated with Run PA accelerated the enzymatic activity but did not influence the microbial community nor their catabolic function. As a result of the increased organic matter degradation rate in PA, Thermobifida proliferated early and played a key role in degrading relatively hardly degradable material by hydrolysis of cellulose into cellobiose.

The catalytic performance and therapeutic effect of nanoparticles varies with shape. Here, we investigated and compared the therapeutic outcomes of ceria nanospheres (Ceria NSs) and ceria nanorods (Ceria NRs) in an in vivo study of mild traumatic brain injury (mTBI). In vivo TBI was induced in a mouse model of open head injury using a stereotaxic impactor. Outcomes including cytoprotective effects, cognitive function, and cerebral edema were investigated after retro-orbital injection of 11.6 mM of ceria nanoparticles. Ceria nanoparticles significantly reduced fluoro-jade B (FJB)-positive cells and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL)-positive cells, and restored mRNA levels of superoxide dismutase 1 (SOD1) and SOD2. They also decreased the cyclooxygenase-2 (COX-2) expression compared with the untreated control group. Comparing the two nanomaterials, Ceria NRs showed less stable and high-energy (100) and (110) planes, which increased the number of active sites. The Ce3+/Ce4+ molar ratio of Ceria NRs (0.40) was greater than that of Ceria NSs (0.27). Ceria NRs (0.059 ± 0.021) appeared to exhibit better anti-inflammatory effect than Ceria NSs (0.133 ± 0.024), but the effect was statistically insignificant (p = 0.190). Ceria nanoparticles also improved cognitive impairment following mTBI compared with the control group, but the effect did not differ significantly according to the nanoshape. However, Ceria NRs (70.1 ± 0.5%) significantly decreased brain water content compared with Ceria NSs (73.7 ± 0.4%; p = 0.0015), indicating a more effective reduction in brain edema (p = 0.0015). Compared with Ceria NSs, the Ceria NRs are more effective in alleviating cerebral edema following in vivo mTBI.

Crystalline metal–organic frameworks (MOFs) are extensively used in areas such as gas storage and small-molecule drug delivery. Although Cu-BTC (1, MOF-199, BTC: benzene-1,3,5-tricarboxylate) has versatile applications, its NO storage and release characteristics are not amenable to therapeutic usage. In this work, micro-sized Cu-BTC was prepared solvothermally and then processed by ball-milling to prepare nano-sized Cu-BTC (2). The NO storage and release properties of the micro- and nano-sized Cu-BTC MOFs were morphology dependent. Control of the hydration degree and morphology of the NO delivery vehicle improved the NO release characteristics significantly. In particular, the nano-sized NO-loaded Cu-BTC (NO⊂nano-Cu-BTC, 4) released NO at 1.81 µmol·mg−1 in 1.2 h in PBS, which meets the requirements for clinical usage. The solid-state structural formula of NO⊂Cu-BTC was successfully determined to be [CuC6H2O5]·(NO)0.167 through single-crystal X-ray diffraction, suggesting no structural changes in Cu-BTC upon the intercalation of 0.167 equivalents of NO within the pores of Cu-BTC after NO loading. The structure of Cu-BTC was also stably maintained after NO release. NO⊂Cu-BTC exhibited significant antibacterial activity against six bacterial strains, including Gram-negative and positive bacteria. NO⊂Cu-BTC could be utilized as a hybrid NO donor to explore the synergistic effects of the known antibacterial properties of Cu-BTC.

Advanced hybrid nanomaterials (nanohybrids) with unique tailored morphologies and compositions have been used for the target-oriented catalysts due to the structural or supportive properties of each moiety and the synergistic properties of the individual components. The rational design and development of nanohybrids by integrating highly porous silica into a nano metal-organic framework (NMOF) are expected to enable unique nanospace engineering in the resulting systems to optimize their utility in the target areas. Herein, we report the design and fabrication of advanced nanohybrids composed of dendritic fibrous nanosilica (DFNS) and DFNS/gold (DFNS/Au) hybrids as the core and zinc-based NMOF (Zn-NMOF) as the shell (DFNS@Zn-NMOF) through a solution-based approach. The combined fibrous morphology of DFNS and micropores of NMOF can be directly employed for nanospace engineering in the resulting multi-compositional and hierarchical systems in a controllable manner. The DFNS/Au dots@Zn-NMOF nanohybrid shows improved catalytic performance in the Knoevenagel condensation reaction, attributed mainly to the cooperative effect stemming from the suitably organized configurations of each component.

International audience; Spin Crossover (SCO) is a promising switching phenomenon when implemented in electronic devices as molecules, thin films or nanoparticles. Among the properties modulated along this phenomenon, optically induced mechanical changes are of tremendous importance as they can work as fast light-induced mechanical switches or allow to investigate and control microstructural strains and fatigability. The development of characterization techniques probing 2 nanoscopic behaviour with high spatio-temporal resolution allows to trigger and visualize such mechanical changes of individual nanoscopic objects. Here we use Ultrafast Transmission Electron Microscopy (UTEM) to precisely probe the length changes of individual switchable nanoparticles induced thermally by nanosecond laser pulses. This allows us to reveal the mechanisms of spin switching, leading to the macroscopic expansion of SCO materials. This study was conducted on individual pure SCO nanoparticles and SCO nanoparticles encapsulating gold nanorods that serve for plasmonic heating under laser pulses. Length changes are compared with time-resolved optical measurements performed on an assembly of these particles.

Recent attempts have been made to develop a thermophilic composting process for organic sludge to not only produce organic fertilizers and soil conditioners, but to also utilize the generated ammonia gas to produce high value-added algae. The hydrolysis of organic nitrogen in sludge is a bottleneck in ammonia conversion, and its improvement is a major challenge. The present study aimed to elucidate the effects of inoculated Neurospora sp. on organic matter decomposition and ammonia conversion during thermophilic composting of two organic sludge types: anaerobic digestion sludge and shrimp pond sludge. A laboratory-scale sludge composting experiment was conducted with a 6-day pretreatment period at 30 °C with Neurospora sp., followed by a 10-day thermophilic composting period at 50 °C by inoculating the bacterial community. The final organic matter decomposition was significantly higher in the sludge pretreated with Neurospora sp. than in the untreated sludge. Correspondingly, the amount of non-dissolved nitrogen was also markedly reduced by pretreatment, and the ammonia conversion rate was notably improved. Five enzymes exhibiting high activity only during the pretreatment period were identified, while no or low activity was observed during the subsequent thermophilic composting period, suggesting the involvement of these enzymes in the degradation of hardly degradable fractions, such as bacterial cells. The bacterial community analysis and its function prediction suggested the contribution of Bacillaceae in the degradation of easily degradable organic matter, but the entire bacterial community was highly incapable in degrading the hardly degradable fraction. To conclude, this study is the first to demonstrate that Neurospora sp. decomposes those organic nitrogen fractions that require a long time to be decomposed by the bacterial community during thermophilic composting.

Hydrothermal treatment (HTT) as a pretreatment method for compost raw material has multiple benefits such as enhanced solubility of organic material, improved bioaugmentation, and reduced biohazard by killing harmful microorganisms. In this study, we pretreated food waste via HTT at 180 °C for 30 min to investigate its effect on food waste composting. HTT generated 8.98 mg/g-dry solid (g-ds) of 5-hydroxymethylfurfural and 4.32 mg/g-ds furfural. These furan compounds were completely decomposed in the early stage of composting, subsequently the organic matter in the food waste started to be degraded. The HTT-pretreated experiment demonstrated less organic matter degradation during composting as well as lower compost phytotoxicity compared to the non-HTT-pretreated experiment, where the conversion of carbon was 25.2% and the germination index value was 55%. HTT probably denatured part of the organic matter and making it more difficult to decompose, thereby preventing the rapid release of high concentrations of phytotoxic compounds such as organic acids and ammonium ions during composting. High-throughput microbial community analysis revealed that only Firmicutes appeared in the HTT-pretreated experiment, however, other bacterial groups also appeared in the non-HTT-pretreated experiment. This was possibly influenced by furan compounds and the changes of easily degradable organic matter to hardly degradable. Bacillus and Lysinibacillus were dominant in both composting experiments during vigorous organic matter degradation, suggesting that these bacterial groups were the main contributors to food waste composting. This study suggests that HTT is advantageous for the pretreatment of easily degradable food waste, as compost with less phytotoxicity was produced.

Despite recent advances toward understanding metallosupramolecular platforms, structural classification remains a challenge because of the high multiplicity and diversity originating from the variety of three-dimensional binding modes of metal ions and multifunctional ligands. In this review, multilevel coordination-driven assembly and its potential implementation in the analysis of a variety of structurally complicated metallosupramolecules are demonstrated. The classification of coordination-driven structures with their respective hierarchy levels is summarized based on the ability of each structural unit to construct ordered molecular platforms. Multilevel assembly is composed of (i) primary, (ii) secondary, (iii) tertiary, or higher-order assembly. The coordination-driven binding modes should differ by levels in a complex. In particular, tertiary assembly involves the use of predefined, well-organized secondary supramolecules as basic modules to build discrete or polymeric structures. Using the suggested concept, coordination-driven metallosupramolecular platforms can be readily classified depending on their respective hierarchical structures. We expect that this simple analytical approach will provide researchers with a more effective understanding of coordination-driven assembly and facilitate the design of new complexes for specialized applications.

International audience; We investigate the spin-state photoswitching process in Au@SCO nanohybrids made of gold nanorods coated by a spin crossover (SCO) shell of polymeric triazole based Fe(II) complexes of [Fe(Htrz) 2 trz] (BF 4). Our research is performed exciting our samples with near-infrared quasi-continuous wave or nanosecond pulse, tunable from visible to near-infrared range. Time-resolved experiments ranging from millisecond down to nanosecond timescales reveal the dynamics during the spin-state transition. Upon excitation, the thermal photoswitching of the sample happens within hundreds of milliseconds for quasi-continuous wave excitation. It happens within tens of nanoseconds for a nanosecond pulse. Compared to the SCO [Fe(Htrz) 2 trz] (BF 4) nanoparticles powder, the peak power of quasi-continuous wave or fluence of the nanosecond laser required to induce the spin state transition in the nanohybrid is reduced.

Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor in pediatric patients, only 22 cases have been reported in literature since 1932. We present an extremely rare case in which AC occurred in a 2-year-old girl, who had a tumor in the right mandible. Radiographic findings showed a multilocular, poorly defined, and mixed radiolucent-radiopaque lesion in the region of teeth #84 to #85, with bone and tooth root resorption. Computed tomography revealed buccal cortex destruction, tumor infiltration of soft tissue, and enlarged nodes. Incisional biopsy showed histomorphological features of AC. Immunohistochemical analysis exhibited a positive result for Cytokeratin (CK) 19 and overexpression of p53 and Ki67. The patient underwent right hemimandibulectomy and neck dissection. The final pathology was consistent with the initial diagnosis of AC. The patient did not exhibit signs of recurrence or metastasis within 2 years postoperatively. Given the rarity of this disease and the age of the patient, this report constitutes a valuable contribution to the current literature.

Coordination polymer particles (CPPs) with a high degree of porosity and multi-functional reaction sites are promising for diverse applications. The integration of open sites favorable for the post-modification of CPPs presents a unique opportunity for the rational design of inorganic materials with target-oriented functions. Herein, we report a shape-controllable synthetic protocol for zinc-based coordination polymer nanocubes (Zn-CPNs). In the synthesis, 2,6-bis[(4-carboxyanilino)carbonyl] pyridine ([N3]) ligand is employed as an efficient shape-directing modulator to control the size and shape of Zn-CPNs. More importantly, the [N3] ligand provides metal binding sites suitable for the decoration of other functional metals such as copper ions. The copper-modified Zn-CPNs (Cu_Zn-CPNs) show good activities in a heterogeneous catalytic reaction.

Morphologically unique silica nanoparticles can be used as effective templates to prepare silica–metal hybrid nanomaterials, which are highly applicable in a variety of areas. Mesoporous silica nanoparticles, which have high surface areas and an abundance of pores, can be used to synthesize mesoporous silica core–metal shell nanostructures with catalytically active sites. In this work, dendritic fibrous nanosilica (DFNS) with a high surface area is successfully employed as a template to synthesize DFNS/Au hybrid nanomaterials. Au nanodots are initially synthesized through the selective reduction of Au ions on the surface of the DFNS after surface modification to form DFNS/Au dots. A seed‐mediated growth method is used to controllably grow Au nanoparticles on the DFNS/Au dots to generate DFNS core–Au nanoparticles shell nanohybrids (DFNS/Au NPs) and DFNS core–Au layer shell nanohybrids (DFNS/Au layers). The catalytic activities of DFNS/Au NPs and DFNS/Au layers in the 4‐nitrophenol reduction reaction are compared.

Lactic acid bacteria are observed during early stages of almost all food waste composting. Among them, 2 types of lactic acid bacteria, Pediococcus (homofermentative lactic acid bacterium) and Weissella (heterofermentative lactic acid bacterium) have been often reported. In this study, the roles of these 2 types of lactic acid bacteria in the composting were tried to elucidate. It has been pointed out that Pediococcus accelerates the composting process by producing lactic acid which prevented acetic acid generation, thus activating indigenous composting microorganisms. On the other hand, this study elucidated that Weissella produced acetic acid of 20 mg g−1 DS, which is harmful to composting microorganisms, resulting in the inhibition of vigorous organic matter degradation. When these 2 coexist in the starting material, whether the composting succceeds or not depends on the ratio of these 2 lactic acid bacteria. If Pediococcus and Weissella ratio was higher than 101.5, acetic acid level was almost 3 times lower than that observed in the composting with their lower ratios of 1 and 10−1, probably because of the interaction of Pediococcus and Weissella resulting in the suppression of Weissella activity, and thus composting was accelerated.

Maintaining proper aerobic conditions is a crucial factor in composting. Positive aeration (PA, blowing) has been widely applied but diffuses the odorous exhaust gas to the atmosphere. Negative aeration (NA, suction) enables to minimize the gas diffusion, but NA has scarcely been applied mainly because there has been no clear answer about the advantage in the organic matter degradation rate in this system. The air in the PA flows from the higher temperature zone (inside the pile) to the lower temperature zone (the top of the pile), while the air in the NA flows in the opposite direction. We hypothesized that the water vapor and NH3 gas produced in the high-temperature zone of PA was more likely to be transported and absorbed/adsorbed in the lower temperature zone than that of NA, which could influence microbial activity during composting. This study quantitatively evaluated the effect of two aeration methods on organic matter degradation during composting. We examined the effect of absorption/adsorption of NH3 on the compost by preventing the compost from drying. We found that PA indeed tended to accumulate more NH3 than NA but did not show large differences, consequently having little influence on the organic matter degradation.

Maximizing the recovery of gaseous NH3 during thermophilic composting of shrimp pond sludges is an attractive approach to produce clean nitrogen used for the cultivation of high-value microalgae. This study investigated the NH3 recovery potential and the related microbial community changes during thermophilic composting of shrimp pond sludges. Three sludges were collected from Malaysian shrimp farms: one was from an earthen pond, another from an earthen discharge channel adjacent to a plastic-lined pond, and one from a plastic-lined pond. The sludges were used as raw materials in examining the recovery of NH3 at three different temperatures using lab-scale composting reactors. Overall, the sludge from the plastic-lined pond produced the most NH3, 3.8 × 10−4 mol/g-dry of the solid sludge, 1.9–3.4 times and 17.2–24.0 times higher than those from the discharge-channel and earthen-pond sludges, respectively. The cumulative NH3 evolution was positively correlated with the volatile solid content of the sludge, clearly indicating that the amount of organic matter was the most important factor for recovering NH3 from shrimp pond sludge. High-throughput microbial community analysis revealed that the dynamics of major bacterial groups differed between sludges, possibly depending on the composition and/or the organic matter quality of the sludge. Rhodobacteraceae was dominant not only in the sludge but also during thermophilic composting of two sludges, suggesting this marine bacterium is one of the key degraders of shrimp pond sludge. Some distinct bacterial groups proliferated only in the discharge-channel sludge (e.g., Ureibacillus) or plastic-lined-pond sludge (e.g., Marinobacterium). This suggests that these bacterial groups played complementary roles in organic matter degradation and/or NH3 production during the thermophilic composting of shrimp pond sludge.

Rod-like gold nanoparticles are directly embedded in a 1D-polymeric spin crossover (SCO) material leading to singular Au@SCO nanohybrid architectures. The resulting architectures are designed to promote a synergetic effect between ultrafast spin-state photoswitching and photothermal properties of plasmonic nanoparticles. This synergy is evidenced by the strong modulation of the surface plasmon resonance of the gold nanorods through the spin-state switching of the SCO component and also the strong enhancement of the photoswitching efficiency compared to pure SCO particles. This remarkable synergy results from the large modulation of the dielectric properties of the SCO polymer upon its thermal switching and the enhancement of the heating of these hybrid nanostructures upon excitation of the surface plasmon resonance of the gold nanorods.

Controlling the behavior of mobile robots to interact with the environment in general and the path planning problem for mobile robots in particular set the requirements for establishing methods for evaluating environmental characteristics and decision making for mobile robot. This paper presents the method of determining the trajectoy of the mobile robot to the target with the shortest distance in the known environment as well as in the unknown environment. The method presented in this paper has been improved from the K-Bug algorithm, combined with the Fuzzy logic for boundary following. The proposed algorithm is simulated with MobileSim software and experimented with Mobile Robot Pioneer 3-AT.

Food waste collected from restaurants, convenience stores, and food-processing factories was mixed with sawdust and subjected to hydrothermal pretreatment at 180°C for 30min to prepare compost raw material. Furan compounds such as 5-HMF (5-hydroxymethyl furfural) and furfural were produced at concentration levels of approximately 8 and 0.5mg/g-ds, respectively, through hydrothermal pretreatment. The furan compounds inhibited the activity of composting microorganisms, thus delaying the start of organic matter degradation during composting. A newly identified fungus, Paecilomyces sp. FA13, which possesses the ability to degrade furan compounds, was isolated and used as an inoculum for the composting of the raw material prepared by hydrothermal pretreatment. By inoculating the FA13 into the compost raw material at 10(5)CFU/g-ds, the degradation of furan compounds was accelerated. As a result, bacterial activity, which contributed to composting, was enhanced, significantly promoting the start of vigorous degradation of organic materials.

This research investigated the panel zone shear behavior of a proposed through-flange connection for steel beams to circular concrete-filled steel tubular (CFT) columns. Four exterior beam-column specimens were designed and tested using cyclic loading applied to the beam end. Three design variables were examined: concrete infill in the column tube, stiffeners to the column tube in the panel zone, and the width of the through-flange plates. Test results showed significant panel zone shear yielding for all specimens. Failure of the specimens was caused by fracture of the column tube near the through-flange plates and crushing of concrete at the stiffener side in the panel zone if concrete infill was present. The use of concrete infill, stiffeners, and 25% wider through-flange plates increased the peak applied load by 156, 7, and 14%, respectively. A model that considers crushing of concrete at the stiffener side as failure mode was proposed to calculate the panel zone shear strength contribution fro...

The Bag-of-Tasks (BoT) behaviour has recently drawn the attention of scheduling researchers [2, 36, 37] and seems to be very common in workloads of parallel systems (up to 70% of jobs [27]) and grids (up to 96% of the total CPU time is consumed by BoTs [11]). To enable a reliable evaluation of BoT-oriented scheduling algorithms, researchers require realistic workload models that take BoTs into account. Regrettably, very few such models are available in the liturature. To our best knowledge, there are only two studies on modeling that incorporate BoTs into their models to generate synthetic workloads for parallel systems [27] and grids [12]. However, these models only focus on fitting the marginal distributions and neglect several other statistical properties of BoTs such as periodicity, autocorrelation and cross-correlation among BoT attributes. We believe that these crucial characteristics deserve to be taken into account in modeling research. Therefore in this paper, we will focus on characterising the BoT behaviour to further improve researchers' understanding of this well-known behaviour in parallel system workloads. In addition, we also study how BoTs affect parallel system performance. Our experimental results indicate that the presence of BoTs leads to a considerable performance degradation, but it is interesting that a realistic association between job arrivals and job runtimes helps BoTs to improve the performance of parallel systems. Moreover, we also show the necessity of using workloads with BoTs in scheduling evaluation to obtain reliable results.

Linear and nonlinear magneto-photonic properties of periodic arrays of nickel nanodimers are governed by the interplay of the (local) optical response of individual nanoparticles and (non-local) diffraction phenomena, with a striking example of Wood's anomaly. Angular and magnetic-field dependencies of the second harmonic intensity evidence Wood's anomaly when new diffraction orders emerge. Near-infrared spectroscopic measurements performed at different optical wavelengths and grating constants discriminate between the linear and nonlinear excitation mechanisms of Wood's anomalies. In the nonlinear regime the Wood's anomaly is characterized by an order-of-magnitude larger effect in intensity redistribution between the diffracted beams, as compared to the linear case. The nonlinear Wood's anomaly manifests itself also in the nonlinear magnetic contrast highlighting the prospects of nonlinear magneto-photonics., 8 pages, 6 figures
