The massive residues of tetracycline (TC) have caused serious harm to the human body and the environment, so it is urgent to explore a portable, on-site, sensitive and selective method to detect TC. In this study, a dual response ratiometric fluorescent probe (S,O-C3N4QDs-CitNa-Eu3+) for detecting TC was constructed by mixing sodium citrate (CitNa), europium ion (Eu3+) and sulfur and oxygen co-doped graphite phase carbon nitride quantum dots (S,O-C3N4QDs) solution in a specific proportion. The S,O-C3N4QDs was initially synthesized by using citric acid and thiourea as the precursors via a hydrothermal route. The blue fluorescence of S,O-C3N4QDs (λem = 445 nm) was decreased while the red fluorescence of Eu3+ was increased (λem = 620 nm) own to the synergistic effect of internal filter effect, static quenching and antenna effect when TC was added to the mixed system containing CitNa and Eu3+. As a result, the ultra-sensitive detection of TC was realized from 0.25 to 120 μM with a detection limit of 1.3 nM. An obvious color change of the solution from blue to purple to red with continuous adding TC was observed such that the semi-quantitative detection of TC can be realized. Moreover, a smartphone APP monitoring platform based on test paper was constructed by using color scanning application, demonstrating that the ratiometric fluorescent probe constructed in this work has great potential in medical and environmental fields.

Compared to the individual fiber, the core problem limiting the mechanical strength of the aramid nanopaper is the weak interfacial bonding strength, and the hydrogen bond-induced aggregation is an important factor influencing the well compositing of aramid nanofibers (ANFs) with other enhancers. In this work, we introduced sodium alginate (SA) as a mechanical additive during the formation process of ANFs to realize the uniform wrapping of the SA on the surface of ANFs. The resultant ANFs/SA paper shows an ultimate strength of 308.23 MPa, a toughness of 42.33 MJ⋅m−3, and an elongation of 21.99%, which are 1.63, 5.16, and 3.12 times of the pure ANFs film. The excellent mechanical performances are attributed to the good dispersion of SA in the ANFs matrix, which can result in the fine physical cross-link and enhanced hydrogen bonding at interfaces. Meanwhile, the ANFs/SA composite also shows favorable electrical insulation behaviors. [ABSTRACT FROM AUTHOR]

Twinning is an important deformation mechanism for magnesium alloys, which has a significant impact on the texture evolution and mechanical properties. Pre-twinning deformation has been considered as an effective method for texture regulation. For each twinning mode, there are six crystallographically equivalent variants. Properly identifying the activated twin and understanding its variant selection criteria are essential for the development of high-performance magnesium alloys. As summarized in this paper, the observed twin variant by the commonly employed electron backscatter diffraction technique can be identified by several approaches, including misorientation analysis, trace analysis and matrix method. Schmid factor analysis was commonly performed to explain the selection of twin variants. To broaden the application scope under complex stress state, a generalized Schmid factor was derived by introducing a stress tensor. The efficiency of Schmid criteria to assess twin variant selection was confirmed to be influenced by the type of the applied stress. To consider the local effect on twin activation, in particular twin-twin transfer and slip-induced twinning, displacement gradient tensor calculation and geometrical compatibility factor analysis have been employed. It was demonstrated that local strain accommodation played a critical role in selecting the variants of cross-boundary twins in magnesium alloys. Assisted with crystal plasticity finite element modeling, the resolved shear stress on twinning and a composite Schmid factor combining the global Schmid factor and geometrical compatibility factor were obtained to better explain the activated twin variants in magnesium alloys. All the above-mentioned Schmid law based criteria and some energy based criteria as well are summarized in this paper. Their applications in evaluating twin variant selection in magnesium alloys are critically reviewed and discussed. [ABSTRACT FROM AUTHOR]

Microalloying has been an important method in aluminum alloy development for decades. Large number of papers have shown that the addition of trace element Erbium (Er) can effectively improve the comprehensive properties of aluminum alloys. Similar with the trace element Scandium (Sc), addition of trace element Er in aluminum alloys could form nano-sized L12-ordered Al3Er precipitates, which was coherent with the Al matrix. However, the dispersion precipitation strengthening effect of Al3Er was more significant than that of Al3Sc, at the same atomic content. In the case of the addition of both Er and Zr, core–shell-structured Al3(Er, Zr) precipitates formed instead of Al3Er precipitates. Those thermally-stable nanosized precipitates could significantly refine the grain size, retard the recrystallization, improve the mechanical properties and corrosion resistance. This paper reviewed several typical Er-containing microalloyed commercial aluminum alloys, like 2xxx (Al–Cu) alloys, 4xxx (Al–Si) alloys, 5xxx (Al–Mg) alloys, 7xxx (Al–Zn–Mg–Cu) alloys, as well as selective laser melting aluminum alloys.

Two-dimensional materials with unique properties have received much attention in recent years. Current research is exploring their potential applications in various fields. Acoustic topological insulators have been an emerging branch in the field of acoustic metamaterials in recent years. Its strong unidirectional transmission capability has potential applications in acoustic sensors, filters, and beamwaves. However, to realize a wide range of applications of acoustic topological materials, it is necessary to solve the problems of multi-band and wide bandgap. To this end, this paper proposes a jointly resonant acoustic topological insulator structure. The structure achieves multi-band filtering, and three filterable bandgaps can be obtained below 6200 Hz. Meanwhile, the total width of the three filterable bandgaps accounts for 65.5% at 6200 Hz and below. In this paper, the band structure is obtained by using the method of finite element simulation. The generation of topological phase transition induced by the rotation angle of the scatterer is analyzed. The pseudo-spin case of the valley hall effect is also analyzed from the point of view of acoustic energy flow, and the existence of edge states is verified. Finally, the unidirectional transport properties possessing backward scattering immunity are verified. The multi-band structure with a great bandwidth means that this work will have great potential for applications in filters. Also, since acoustic topologies based on the Valley hall effect do not possess strong defect immunity, this work proposes to utilize defect states as acoustic switches. [ABSTRACT FROM AUTHOR]

With the development of society and technology, machinery and equipment have enhanced our work efficiency but have also introduced various hazards, such as electromagnetic radiation, medical, industrial, and agricultural rays. The harms these radiations inflict on human health are significant, with severe cases leading to cancer, disability, or even life-threatening situations. Therefore, effective protective measures in some fields are crucial. This paper firstly summarized the basic principles of radiation protection for different rays, then systematically introduced the widely used manufacturing methods for flexible radiation shielding materials, including weaving with metal fibers, fiber blending, silver-plated fibers, and so on. Subsequently, the paper reviewed the testing methods of radiation-protective clothing materials. Finally, it comprehensively concluded the discussions on flexible radiation shielding materials and offered a perspective on their future development trends. [ABSTRACT FROM AUTHOR]

Due to increased environmental awareness, the depletion of fossil fuels, and expanding ecological concerns, today's society has a larger need for environmentally friendly materials. The idea of sustainable development of environmental material resources with enhanced economic activities was born from the rise in ecological consciousness. The textile industry generates enormous amounts of cotton waste. The environmental impact of disposing of this cotton waste makes it difficult for the textile sector to dispose of the vast amounts of produced cotton waste. As a result, all-cellulose composites (ACCs) have piqued the interest of researchers in recent years. All-cellulose composites are cellulose-based mono-component cellulose composites in which the reinforcing phase is typically composed of high-strength cellulose fibres, and the matrix is composed of regenerated cellulose. This composite type is distinguished by its exceptional interfacial compatibility and biodegradability due to the matrix and reinforcing phase having common cellulosic compositions. ACCs will become a more alluring option as enterprises prioritize sustainability and environmental responsibility because they can be recycled and reused rapidly and simply. This will contribute to less waste and enhance the overall sustainability of our society. This review paper discusses various methods to develop ACCs, textile waste-based thermoset and thermoplastic composites and textile waste-based cellulose composites (TWCCs). This review paper emphasizes approaches to develop TWCCs and the challenges and opportunities in TWCCs. [ABSTRACT FROM AUTHOR]

Fiber-reinforced polymer (FRP) composites are widely used to reinforce and repair buildings due to their high strength, corrosion resistance, lightweight, and convenient of construction. The interfacial properties between FRP and the reinforced buildings play a very important role in the effective transfer of stress and largely determine the service hours of the reinforced structures. Therefore, this paper reviews the research progress on the interfacial properties of FRP reinforced concrete. First, the composition of FRP reinforcement system is introduced. EB-FRP and NSM-FRP reinforcement methods are suitable for reinforcing different buildings. Then, the influence factors of the interfacial properties are highlighted. The choice of interfacial agent, roughness of the reinforced concrete surface, temperature and environment have very important impact on the reinforcement effect. Finally, the main damage modes and failure mechanisms of the interface between FRP and the reinforced concrete are summarized. The choice of the interfacial agent determines the main failure mode. This paper provides a theoretical basis for the further research on the interface damage mechanism of FRP reinforced concrete. [ABSTRACT FROM AUTHOR]

Purpose. High-fidelity mannequins are increasingly used to train the medical staff on many medical procedures. Lately, a new challenge regarding echogenic materials to build ultrasound-responding phantoms has emerged. The challenge is to find materials with a suitable combination of ultrasound velocity and consistency to the touch. Methods. Bibliographic research was performed to identify materials with promising stiffness, shape retention, and ultrasound velocity combinations. As-standardized-as-possible specimens were realized and tested using an A-mode ultrasound machine to evaluate the US velocity through them. Four differently doped silicones, five gelatin-based materials, five synthetic gelatins, and a 3D printable resin were included in the study. After being tested, the materials were monitored for 12 days to assess their durability and shape retention and tested again to evaluate the ultrasound velocity's stability. In the paper, the results of the characterization and follow-up of the materials are presented. Results. Outcomes show that gelatins are exceptional soft tissue-mimicking materials in terms of ultrasound velocity and consistency to the touch, but are poor in terms of overtime stability and therefore suitable for disposable short-term phantoms only. Doped silicones present lower ultrasound velocity compared to the reference value of 1540 m/s found in the literature, but excellent overtime stability, and shape retention properties. Values close to biological ones were also given by the Elastic 50A and by polyvinyl chloride plastisol. Conclusion. The paper gives a quantitative overview of the fidelity of both already-in-use and non-conventional materials, focusing on the ultrasound velocity value through them and their longevity in terms of macroscopically observed dehydration, shape retention, and bacterial onset.

This paper reviews the research progress of agricultural waste-based activated carbon (AWAC), including the sources and characteristics of agricultural waste, and the effects of raw material characteristics and activation conditions on the performance of AWAC. It analyzes the advantages and disadvantages of various preparation methods of AWAC. Additionally, it explains the research status of AWAC in wastewater treatment, gas adsorption, catalyst carrier, and energy carrier. Finally, this paper summarizes the advantages and limitations of using agricultural wastes as raw materials for AC, and provides a prospect for raw material development, process optimization, and application expansion, taking into account the shortcomings of current research.

The formation of nanogold and nanosilver composites with cellulose paper fibres and the associated lignin component together with their antimicrobial properties are presented. This follows on from the proprietary technology of Johnston et al. [] wherein they used nanogold and nanosilver entities in wool fibres to provide novel colourfast colourants in textiles with additional effective antimicrobial and catalytic properties. The nanogold and nanosilver are formed and bound directly onto the unbleached lignin-containing paper fibres without the use of an external linker molecule. For this, the lignin was found to play an essential role and hence the methodology presented is applicable only to cellulose in the form of unbleached kraft fibres and mechanical pulp. The phenol and possibly the aromatic methoxy groups of the lignin are considered to reduce Au to Au and Ag to Ag, respectively, and bind the nanogold and nanosilver to the fibre surface. SEM images and UV-Visible spectra confirm the formation of nanogold and nanosilver on the fibre surface. Changes in the IR spectra are consistent with the above role of the phenol and methoxy groups. The resulting nanogold-unbleached kraft fibres are purple and the nanosilver-unbleached kraft fibres are yellow due to the surface plasmon resonance effects of nanogold and nanosilver respectively. The nanogold-unbleached kraft fibres and particularly the nanosilver-unbleached kraft fibres exhibit very effective antimicrobial properties at low levels of gold and at very low levels of silver. In this way we have been able to produce novel nanogold paper and nanosilver paper fibres and products which collectively exhibit the properties of the nanomaterials and the fibre substrates in a synergistic way. This provides the opportunity for developing new functional paper products for antimicrobial packaging, medical dressings, and clothing. [ABSTRACT FROM AUTHOR]

The recent developments in the aeronautical structure industry have seen a sharp rise in the use of polymer composite materials. The performances of all aerodynamic surfaces are heavily dependent on the shape and the surface form. The modification of these surfaces due to condensation and melting of ice can cause catastrophic decreases in the aerodynamic performance. In this study polymer composite materials as heater were made and studied. The feasibility of using advanced polymer composites for de-icing application was validated and studied through experiments. It consists of thin carbon nanotubes (CNTs) Bucky paper placed between two glass fibers veils and then infiltrated with an epoxy polymer resin and cured. The composite can be heated up very quickly using an electrical power source. The idea of using this new material as a heater and de-icing material was explored experimentally. For that purpose, the temperature distribution was monitored at different positions of the panel using thermal imaging. Experimental results show that the surface temperature of the panel increases gradually as the heating time increases. This temperature increased in a short time period of heating time, implying that the composite panels with CNTs Bucky paper display an excellent heating performance. [ABSTRACT FROM AUTHOR]

Silver nanowires find use in a myriad of applications, including communication systems, sensors, medical devices and electrical equipment. Temperature-dependent electrical and thermal properties of chemically derived silver nanowires are rarely explored. In the present work, seed-mediated synthesis of silver nanowires has been carried out, and their electrical and thermal conductivity at 300 K is found to be 1.848 × 107 S/m and 64.8 W/mK, respectively. A screen-printable ink of silver nanowires is formulated and printed on low-cost and widely used substrates like paper and cotton fabrics. Flexible printed electrodes could be made possible with uniform printed structures obtained in cotton fabric and paper substrate. The printed pattern exhibited sheet resistance of 0.7 Ω/sq. Screen-printed silver nanowires on paper show shielding efficiency of 99.9% in X band, which promotes them as excellent candidates in fabricating lightweight electronic devices by a one-step printing process.

Nowadays, the scientific community emphasizes the use of reversible and non-toxic materials in the field of cultural heritage. Biopolymers are one of the alternative materials to synthetic polymers and solvents that are dangerous for human health and for the environment, applied in consolidation and coating treatment. Natural biopolymers may be divided into polysaccharide, protein, and polyester: All of them are low cost, eco-friendly, and biocompatible, besides many physicochemical characteristics such as being transparent, soluble in water, hydrogel, and film-forming, and can be easily functionalized. The addition of nanoclay, essential oil, and active molecules improves the physicochemical properties of biopolymers and proposes smart response abilities to the new composite material. This work is intended to provide an overview of the development of biopolymers by considering the most general aspects and scanning the diverse substrates of application for the conservation and protection of cultural heritage.

The field of tissue engineering involves various methodologies employed to improve or replace biological tissues with extracellular matrices (ECMs). Significant progress has been made, particularly in the fabrication of three-dimensional (3D) scaffolds for replacing damaged tissues or organs. The current review broadly focuses on the various research works carried out involving the use of biomaterials (biopolymers, bio-ceramics and dopants) in this area. A detailed discussion on several scaffold-making modern technologies has also been provided, along with a demonstration of different characterization techniques. Though a number of review papers have been published on biomaterials and fabrication techniques, a very small number focuses on the clinical trials carried out and the commercialization of scaffolds in the biomedical field. Thus, a critical analysis and detailed discussion of some of the clinical trials, market growth, and future demands have been presented in this paper. [ABSTRACT FROM AUTHOR]

The small punch (SP) test has been widely used in applications where conventional mechanical tests cannot be performed; this paper predicts the material strength from the SP test results by empirical correlations method. The yield strength (YS) and ultimate tensile strength (UTS) models serve to associate the load–displacement (LD) curves of SP tests with the stress–strain data of uniaxial tensile tests, and then, the feasibility of these models at different temperatures is investigated. Using the Pearson's correlation coefficient (PCC) method, the ideal strength equations are accessed from past studies for the cast superalloys, including ZG15Cr2Mo1, P91, 316H, and Hastelloy X, whereas the validation results of the additively manufactured (AM) GH4169 alloy are not satisfactory. As a result, considering the unique manufacturing process of AM GH4169, this paper develops a YS model with correlation coefficients higher than 90% between the calculated and actual values and proposes a UTS formula with estimation errors less than 3.5%. Furthermore, with the purpose of superior strength prediction results, the discussion of the SP test velocity reveals that 0.50 mm min−1 had wide adaptability to various strength models and operating temperatures.

Phagraphene is a newly proposed two-dimensional allotrope of carbon. Its structure resembles that of a defective graphene sheet. The unit cell structure of phagraphene consists of a 5–6–7 ring sequence due to which it possesses lower energy than most carbon allotropes. Phagraphene has properties, namely thermal conductivity of 218 ± 20 W/mK and 285 ± 29 W/mK, along armchair and zigzag directions, respectively, a tensile strength of 85 ± 2 GPa, the elastic modulus of 870 ± 15 GPa along armchair and 800 ± 14 GPa along zigzag direction, and fracture strain of the same order as that of pristine graphene. Density functional theory and molecular dynamics simulations have proved the unique electronic properties of phagraphene, namely direction-dependent Dirac cones, tunable Fermi velocities, quasi-direct band gap, to be comparable with pristine graphene. Based on molecular dynamics and density functional theory investigations, phagraphene is capable of being used in Li-based batteries and thermoelectric devices as anode material due to its good adsorption properties and remarkably good doping characteristics. Such characteristics can lead to a future trend of analyzing such allotropes because phagraphene can provide potential applications in atmospheric pollutant-detecting and drug-carrying properties in ailments like cancer. This paper is a nascent one discussing all the previous works on molecular dynamics simulations of phagraphene and tries to serve as the leading one for researchers interested in this field. This paper summarizes the mechanical and thermal properties of phagraphene estimated using molecular dynamics simulations as studied in previous works. The study shows that molecular dynamics has a good application in studying such a novel carbon allotrope. The discussions made in this paper thematize phagraphene's properties as a next-generation material and can help the researchers in a qualitative overview. [ABSTRACT FROM AUTHOR]

Catalytic ceramic papers were developed by incorporating Pt-NaY zeolite to ceramic papers. The necessary mechanical strength was enhanced by the addition of natural borate compounds, which confer elasticity and resistance similar to those obtained using colloidal suspensions, which are the most commonly used binders. Pt-NaY zeolite was incorporated into ceramic papers either during the papermaking process or by spraying a zeolitic suspension on ceramic papers. The partial encapsulation of the faujasite by the sintering of the borate compound during the calcination step made catalytic ceramic papers less active toward the CO oxidation reaction than the corresponding traditional systems (Pt-NaY zeolite coated onto cordierite monoliths or the powder Pt-NaY faujasite). Light-off curves indicated that the activity of Pt-NaY zeolite was preserved when incorporating the zeolitic component by spray, in which case the CO oxidation reaction ran away at ca. 130 °C, and the total CO conversion was achieved at 150 °C, maintaining 100 % CO conversion for more than 90 h.

Bi(Fe Al)O ( x = 0, 0.1, 0.3, 0.5, and 0.7) samples were synthesized by a simple hydrothermal method. The samples were characterized by X-ray diffraction, scanning electron microscopy, Fourier transformed infrared spectra, N-sorption, and UV-Vis diffuse reflectance spectra, and their photocatalytic activities were evaluated by the degradation of methyl orange under visible-light irradiation. The results reveal that the Al substitution can effectively improve photocatalytic performance, which is attributed to the increase of surface area, the improvement of energy band structure, and the distortion of the Fe-O octahedron in Al-substituted samples. In addition, it is found that the photocatalytic activity to decompose methyl orange under visible-light illumination increases monotonically as x increases from zero to 0.5 in Bi(Fe Al)O and then decreases for x = 0.7, which is believed to be associated with the distribution of Fe ions over the octahedral and tetrahedral sites.

Bio-based superhydrophobic coatings have attracted great attention owing to their environmental friendliness and potential applications. Among them, cellulose ester-based coatings show excellent superhydrophobicity. Even so, their rational design and performance modulation have been rarely concerned, which is of great importance to their practical applications. Herein, we adjusted the superhydrophobicity and self-binding strength of α-cellulose 10-undecenoyl ester (CUE) coatings (used as a model) by changing the degree of substitution (DS) value. The DS-induced particle size of the CUE played a key role in the cluster formation for the superhydrophobicity and the generation of contact area for the binding force. The CUE size displayed a normal distribution with the increase in DS value, and a low coating amount as well as a high contact area could be realized from a large particle size. The optimum DS value of the CUE coating was 0.44–0.94. This research may provide a new perspective for the design of stable bio-based superhydrophobic coatings. [ABSTRACT FROM AUTHOR]

Inkjet printing technology holds a great potential for fabrication of biosensor device. An optimized programmed printing makes the processing steps easier on a variety of substrates at low cost. The drop-on-demand piezoelectric mode of printing can construct a design pattern with low volume of material at specified position onto a suitable substrate. But to achieve this successfully, a formation of stable ink suspension remains the most challenging task. In recent times, nanoparticles are considered to pave a way for miniaturization of biosensing devices. Thus, we synthesized, characterized and investigated the stability of magnetic Fe3O4 nanoparticles stabilized by the polyamidoamine (PAMAM = N(CH2CH2C(O)NHCH2CH2NH2)(CH2CH2N(CH2CH2C(O)NHCH2CH2NH2)2)2) dendrimer (PAMAM@Fe3O4). A best stable ink dispersion of PAMAM@Fe3O4 nanoparticles was obtained in a solvent mixture of 70% ethylene glycol and 30% distilled water. The nanoparticle ink with surface tension of 57.47 mN/m and viscosity of 5.45 mPa/s formed a narrow and uniform printed pattern onto graphene paper. Further, as a model protein for future biosensing application, antibody against alpha-fetoprotein was conjugated onto the dendritic surface and printed onto graphene paper. The characterization of the printed pattern by TEM revealed spherical morphology, whereas SEM provided evidence of difference in printed line width and spacing of nanoparticles and antibody conjugated nanoparticles. As a proof-of-concept, the study demonstrated a printable ink dispersion based on PAMAM@Fe3O4 nanoparticles for future miniaturization of biosensing steps on a chip-based platform.

Mineral fillers are among the most important raw materials of paper. In papermaking, a filler is typically mixed as such with the fibrous stock prior to the forming section where it, together with the fibers and fines, forms a paper web with heterogeneous three-dimensional composite structure. The filler is eventually located both in the paper pores and between adjacent fibers. When light interacts with a multitude of solid-air interfaces occurring in such a structure, complicated light scattering effects take place. These effects are essential for appearance development, viz. brightness and opacity. Fillers contribute to these effects by increasing the number of such interfaces. Many fillers also cost significantly less than fibers. Therefore, it is advantageous to introduce as much filler as possible. It is also well known, however, that filler prevents formation of hydrogen bonding and is hence detrimental for strength development. In addition, the legislation of European Union favors increasing recovery of paper and packaging products, e.g., for energy production. However, as a side product of paper waste incineration, significant amounts of ash is formed. Hence it would be advantageous to replace inorganic fillers with combustible organic materials. We have fabricated a novel aluminum silicate spot-coated starch-based filler. The results indicate that when silicate is introduced in paper on the surface of starch granules benefits in light scattering and strength development can be achieved. [ABSTRACT FROM AUTHOR]

Methylene blue (MB) was intercalated into layered potassium titanoniobate (KTiNbO5) through a guest–guest exchange method by use of the intercalation compound n-C4H9NH3 +–TiNbO5 as a precursor. The MB+/H+–TiNbO5 nanocomposite has been characterized by XRD, SEM, IR, TGA, UV, elemental analysis, and electrochemical cyclic voltammetric measurements. From the XRD and elemental analysis results, we proposed that the MB+ cations formed a single layer standing vertically to the titanoniobate nanosheets together with H+. The CV curves of the MB+/H+–TiNbO5 nanocomposite thin film exhibited a fine diffusion-controlled redox process, which hints the possibility of being utilized as an electrode modifying material.
