Abstract

Outbreaks due to multidrug-resistant Candida auris have emerged as a large threat to modern medicine. Since skin colonization and environmental contamination have been identified as a precursor for outbreaks, we evaluated the antifungal activity of ultraviolet-C light using mercury vapour lamp with a peak emission of 254 ± 2 nm and octenidine dihydrochloride against C. auris clinical isolates. Octenidine dihydrochloride was found effective at significantly lower concentrations (0.00005-0.0004%) than those currently used in the clinical setting (0.05-0.1%). Scanning electron microscopy images show destruction of the organism within 6 h of exposure to 0.0005% octenidine dihydrochloride. Ultraviolet-C light could kill all C. auris with 15 min exposure.

Abstract

We report a highly sensitive Localized surface plasmon resonance (LSPR) based photonic crystal fiber (PCF) sensor by embedding an array of gold nanospheres into the first layer of air-holes of PCF. We present a comprehensive analysis on the basis of progressive variation of refractive indices of analytes as well as sizes of the nanospheres. In the proposed sensing scheme, refractive indices of the analytes have been changed from 1 to 1.41(RIU), accompanied by alteration of the sizes of nanospheres ranging 40–70 nm. The entire study has been executed in the context of different material based PCFs ( viz . phosphate and crown) and the corresponding results have been analyzed and compared. We observe a declining trend in modal loss in each set of PCFs with increment of RI of the analyte. Lower loss has been observed in case of crown based PCF. The sensor shows highest sensitivity ∼27,000 nm/RIU for crown based PCF for nanosphere of 70 nm with average wavelength interrogation sensitivity ∼5333.53 nm/RIU. In case of phosphate based PCF, highest sensitivity is found to be ∼18,000 nm/RIU with an average interrogation sensitivity ∼4555.56 nm/RIU for 40 nm of Au nanosphere. Moreover, the additional sensing parameters have been observed to highlight the better design of the modelled LSPR based photonic crystal fiber sensor. As such, the resolution (R), limit of detection (LOD) and sensitivity (S) of the proposed sensor in each case (viz. phosphate and crown PCF) have been discussed by using wavelength interrogation technique. The proposed study provides a basis for detailed investigation of LSPR phenomenon for PCF utilizing noble metal nanospheres (AuNPs). [ABSTRACT FROM AUTHOR]

Abstract

Electronic transport through graphene magnetic barriers is studied theoretically in presence of an external time harmonic scalar potential in the framework of non-perturbative Landau–Floquet Formalism. The oscillating field mostly suppresses the transmission for rectangular magnetic barrier structure and exhibits the Fano resonance for multiphoton processes due to the presence of bound state inside the barrier. While, for a pair of delta function barriers of larger separation, the oscillating potential suppresses the usual Fabry–Perot oscillations in the transmission and a new type of asymmetric Fano resonance is noted for smaller separation, occurring due to extended states between the barriers.

Abstract

The modal characteristics of photonic crystal fibers (PCF) with guiding cores consisting of seven missing air holes are investigated with effective index method. We incorporate two different composites – phosphate and crown and systematically analyze the modal characteristics with good control from structural parameters i.e., diameter ( d ) and pitch ( Λ ) in the E and L band of communication. The comprehensive analysis of these two varying PCFs suggests that crown PCF exhibits more spot size and good coverage of V parameters relative to phosphate in the same communication band implicating low loss as well as divergence with better tuning with respect to structural parameters. We also observe good correlation between the theoretical and experimental values. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Nd:YAG laser microdrilled holes on gamma-titanium aluminide, a newly developed alloy having wide applications in turbine blades, engine valves, cases, metal cutting tools, missile components, nuclear fuel and biomedical engineering, are important from the dimensional accuracy and quality of hole point of view. Keeping this in mind, a central composite design (CCD) based on response surface methodology (RSM) is employed for multi-objective optimization of pulsed Nd:YAG laser microdrilling operation on gamma-titanium aluminide alloy sheet to achieve optimum hole characteristics within existing resources. The three characteristics such as hole diameter at entry, hole diameter at exit and hole taper have been considered for simultaneous optimization. The individual optimization of all three responses has also been carried out. The input parameters considered are lamp current, pulse frequency, assist air pressure and thickness of the job. The responses at predicted optimum parameter level are in good agreement with the results of confirmation experiments conducted for verification tests. [Copyright &y& Elsevier]

Abstract

Abstract: The scattering of a bound Frohlich large polaron in the presence of a coulomb impurity center as well as a linearly polarized laser field is studied. The differential (DCS) as well as the momentum transfer cross sections (MTCS) and the conductivity depend remarkably on the electron–phonon coupling ( ) and the strength of the coulomb impurity ( ). The strongly bound polaron is found to be reluctant to contribute to the conductivity which is justified physically. The curves for MTCS and conductivity verses and appear to be complementary, indicating the possibility of controlling the mobility and thereby conductivity by varying one of the parameters. This behavior indicates the possibility of optimizing the composition of optoelectronic materials where laser is the dominant source of excitation. [Copyright &y& Elsevier]

Abstract

Abstract: A theoretical model is proposed to study the ballistic electron transport for a quasi-periodic multibarrier structure where two different barrier shapes are arranged according to the Thue–Morse sequence. Important tunneling features are revealed form such arrangements. It is noted that the tunneling band spectrum could be fragmented by tailoring the shape of the barriers in the structure. Results for the transmission coefficients and the current densities are compared with the corresponding periodic and single shape barrier arrangements. The quasi-periodic structure consisting of the rectangular and triangular barrier shapes is suggested to be more suitable for the electronic and opto-electronic devices due to its high negative differential conducting effect.

Abstract

Abstract: Dynamics of the Dirac fermions, in particular the transmission coefficient and the resonant tunneling lifetime are studied across a bilayer graphene electrostatic double barrier structure modulated by an in plane homogeneous electric field. Asymmetric Fano type resonances are noted for the first time in the transmission spectrum of the bilayer graphene nanostructures and are found to be highly sensitive to the direction of incidence of the charge carriers and the applied homogeneous electric field. The effect of the external field on the extended and the evanescent modes is also analysed. Resonant tunneling lifetime is found to be highly anisotropic in nature. The chiral carriers are either accelerated or decelerated by the electric field depending on the energy of the quasi-bound states, the angle of incidence and the magnitude of the applied field. Effects of the external field on the localization of the chiral carriers are also discussed. [Copyright &y& Elsevier]

Abstract

Abstract: Nanocrystalline silicon solar cells were enhanced with a photonic crystal back-reflector. Rigorous scattering matrix simulations were used to optimize a photonic crystal back-reflector consisting of a triangular lattice of nano-holes, with a pitch near 800nm. The photonic crystal back-reflector with a pitch of 800nm was fabricated on the crystalline silicon substrate by photolithography and reactive-ion etching, and coated with silver and zinc oxide. Nanocrystalline silicon solar cells were grown on the patterned substrates. We observed ∼7% enhancement of the absorption and photo-generated current relative to a Ag/ZnO substrate, with an enhancement ratio of 1.5 near the band edge. Significant enhancement occurred in photon absorption at near infrared wavelengths greater than 700nm, due to diffraction resonances of the incoming light. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: A multi-scale model encompassing pad response and slurry behavior is developed to predict scratch propensity in a chemical mechanical planarization (CMP) process. The pad response delineates the interplay between the local particle level deformation and the cell level bending of the pad. The slurry agglomerates in the diffusion limited agglomeration (DLA) or reaction limited agglomeration (RLA) regime. Various nano-scale slurry properties significantly influence the spatial and temporal modulation of the material removal rate (MRR) and scratch generation characteristics. The model predictions are first validated against experimental observations. A parametric study is then undertaken. Such physically based models can be utilized to optimize slurry and pad designs to control the depth of generated scratches and their frequency of occurrence per unit area. [Copyright &y& Elsevier]

Abstract

Nanophotonic structures of indium telluride having barbed wire morphology exhibits second order non-linearity. This distinctive non-linear behavior is leading to the generation of second harmonics. Here, we demonstrate low power driven SHG by barbed wire indium telluride system by tuning polarization of the fundamental laser beam in a perpendicular orientation to the axis of the nanostructures. The energy corresponding to the second harmonic is found to be saturating toward higher range of polarizing angles. This study will lead to implementation of the structure in photonic applications negating the influence of polarization to a wide extent. Apart from this, when the nanostructure is subjected to low potential driven Kerr opto-electric non-linearity, the system reveals a critical electric field exhibiting intensity reversal.

Abstract: The tunneling escape rate is calculated on the basis of ballistic miniband transport of electron in the presence of external electric field. The variation of the miniband escape rate is reported as functions of barrier and well widths as well as the externally applied bias. Interesting features with regard to the electric field modulation are observed in the semiconductor heterostructures with small barrier and well widths. For the system with constant periodic length, the maximum confinement of carriers is found for the well width almost equal to half of the barrier width. [Copyright &y& Elsevier]

Abstract

The photo-degradation of polymer solar cells is a critical challenge preventing its commercial deployment. We experimentally fabricate organic solar cells and characterize their degradation under solar simulators in an environmental chamber under nitrogen flow, without exposure to oxygen and moisture. We have developed a thermally stable inverted organic solar cell architecture in which light induced degradation of device characteristics can be reversibly annealed to the pristine values. The stable inverted cells utilized MoO x layers that are thermally treated immediately after their deposition on the organic layer, and before metal cathode deposition. Organic solar cells that are photo-degraded in the presence of oxygen, however show irreversible degradation that cannot be thermally recovered. The decrease of organic solar cell characteristics correlates with increases in mid-gap electronic states, measured using capacitance spectroscopy and dark current. It is likely the photo-induced defect states caused by local H motion from the alkyl chains to the aromatic backbone, can be reversibly annealed at elevated temperatures after photo-degradation. Our results provide a pathway for improving the stability of organic photovoltaics. [ABSTRACT FROM AUTHOR]

Abstract

• To fabricate microchannels on transparent material. • PMMA micro-channelling in an open-air environment using a Nd: YAG laser. • Predictions and empirical outcomes are closely aligned, demonstrating the superiority of the model. Among the fastest growing basic materials, polymers have good strength-to-weight ratios, easy to shape, relatively economical, and recyclable which enabled it to become substitutes for metals and alloys in the fields of medical, automobile, aerospace, electronics, thermal and chemical engineering. But a thick transparent PMMA plate creates deep sub-surface cracks due to the burning and charring of polymeric chains, making the operation with Nd: YAG laser radiation extremely difficult. In the current research, a 75 W nanosecond pulsed Nd: YAG laser system is applied to make micro-channel with adequate depth on a thick transparent PMMA plate by using transmission cutting technique. The input process factors considered are pulse width, laser power, cutting speed, and pulse frequency in order to examine the quality characteristics, the depth of cut and heat affected zone (HAZ) in and around the formed micro-channel. To design the experiment of laser transmission channelling of thick PMMA plate of 11 mm, a central composite design (CCD) methodology is used. Due to open-air laser processing, undesirable laser processing effects have been minimised, resulting in a finer and cleaner micro-channel structure with adequate depth of cut, kerf width and minimal Heat Affected Zone (HAZ) width with laser power of around 9 W, pulse frequency of around 33 kHz and cutting speed of 2 mm/sec.

Abstract

We design, simulate and fabricate enhanced thin film silicon solar cells using periodically textured photonic crystal substrates. We utilize a thin film absorber layer consisting of a superlattice of alternating hydrogenated amorphous silicon (a-Si:H) and nano-crystalline silicon (nc-Si). Rigorous vectorial simulations optimized the periodically patterned solar cells by solving Maxwell?s equations in Fourier space. Simulations found optimized architectures for a triangular lattice of metallic nano-cones as a back-reflector, and a conformal solar cell geometry. The periodically patterned photonic crystal based substrates achieve (1) high diffraction, enhancing the path length of light in thin absorber layers and (2) plasmonic concentration of light intensity. Simulations predict an absorption enhancement of 43% for a 12-period superlattice of 800 nm thickness. The optimized pitch of the photonic lattice is near 700 nm. Experimentally the periodically patterned substrates were fabricated with nano-imprint lithography, and utilized as a substrate for the superlattice cells. We measured a large photo-current enhancement between the textured photonic crystal based superlattice cell and the flat cell of 21%, together with long-wavelength quantum efficiency enhancements beyond 600 nm. This is an approach to achieving thin film solar cells with high currents through advanced light-trapping techniques on novel materials. [ABSTRACT FROM AUTHOR]

Abstract

• WS 2 nanosheets deposited on Cu electrodes is reported here. • The scheme exhibits non-ohmic behavior on addition of heavy metal ions. • Additionally, the current also gets enhanced due to incorporation of metal ions. • The I-V characteristics are found to be reversible. We herein report an atypical electrical behavior of WS 2 nanosheets drop casted on Cu electrodes. The addition of heavy metal ions on this platform results in non-ohmic behavior, accompanied by a dramatic rise of current. Additionally, this atypical behavior is found to be reversible. The proposed platform regains its ohmic behavior upon removal of these ions from the nanosheets. It is envisioned that this unusual characteristic will pave way for more research in the field of sensing as well as in relevant fields. [ABSTRACT FROM AUTHOR]

Abstract

• Laser drilling of Monel k-500 superalloy which is based on laser sawing approach. • To reduce hole taper and HAZ in low power fiber laser trepan drilling. • Development of laser sawing machine the recent study bears a great influence. Monel k-500 is a nickel-copper alloy with excellent resistivity towards corrosion, strength and hardness. This makes drilling of precision holes into the super alloy tricky. However, laser beam machining (LBM) employing low power fiber laser has been a potential and successful process in performing laser trepanned drilling operation on nickel based super alloy to produce superior quality holes. The laser drilling process involves a number of process parameters. Each of it is important for the success of the drilling operation. This research paper studies the process parameters and the performance characteristics of laser drilling on difficult to cut Monel k-500 super alloy. Input process parameters for this study include sawing angle, power setting, duty cycle, pulse frequency and trepanning speed. An experiment matrix has been designed to establish the relation between each significant process parameter and hole characteristics like hole taper and heat affected zone (HAZ). Teaching learning-based optimization (TLBO) algorithm has been applied to perform single objective optimization and multi objective optimization to achieve optimized values of hole taper and HAZ. It is also demonstrated that the algorithm used in the study is a powerful tool capable of obtaining optimal parameters setting of LBM. [ABSTRACT FROM AUTHOR]
