Background: Mould growth on coated wood products during shipment is the foremost apprehension for most of the wood industries in India. Well finished wood products tend to get deposited by staining moulds superficially in high humidity conditions during shipment. Though wood disfiguring fungi (stain moulds) normally h…
Electronic and optical properties of Germanium-doped (Ge-doped) silica optical fiber are investigated by employing first-principle methods. The substitution of a Ge atom with a Silicon (Si) atom or an Oxygen (O) atom in different “Si–O–Si” membered rings is analyzed. Compared with the experimental data observed at aro…
Background: Nanoheterostructures of ZnFe2O4–ZnO is a potential functional material synthesized by various complicated synthesis processes. However, most of the processes are not at all cost effective because these generally require high-temperature treatment as well as long reaction time and complicated experimental p…
A computer measurement system, designed and built by authors, dedicated to location and description of partial discharges (PD) in oil power transformers examined by means of the acoustic emission (AE) method is presented. The measurement system is equipped with 8 measurement channels and ensures: monitoring of signals…
In this work, the calculated electron density difference, Bader charge analysis and the density of states (DOS) of SnO2–TiO2-nanotubes (NTs) indicate that the electrons are transferred from the Ti atoms of TiO2into the O atoms of (SnO[Formula: see text] in SnO2–TiO2-NTs and the supported (SnO[Formula: see text] cluste…
The CuCoMnX (X = Si, Sn, Sb) equiatomic quaternary Heusler alloys (QHAs) are studied for phonon spectra by using density functional theory. The crystals exist in three possible structures Y-type I, Y-type II and Y-type III on the basis of their crystallographic positions. Y-type III structural arrangements proved to b…
Abstract Peptide‐mediated self‐assembly is a prevalent method for creating highly ordered supramolecular architectures. Herein, we report the first example of orthogonal C−X⋅⋅⋅X−C/C−X⋅⋅⋅π halogen bonding and hydrogen bonding driven crystalline architectures based on synthetic helical peptides bearing hybrids of l ‐sul…
Color centers in diamond have unique applications as nanoscale field sensors. In particular, in the case of strain field, they are key components for the realization of strain-coupled hybrid spin-oscillator systems. Here, we report on the strain sensitivity of the color center emitting at 2.65 eV in diamond nanoscale…

Monte Carlo simulations in the isothermal-isobaric ensemble are used to investigate the formation of an ordered, biaxial nematic phase in a binary mixture of thermotropic liquid crystals. The orientational dependence of the interaction between molecules of each pure component is the same as in the well-known Maier-Sau…
Semi‐transparent poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) thin films are deposited on top of a glass substrate by using a spraying method with different solvent viscosities. The resultant films are characterized through surface profiler, broadband transmittance spectrometer and Raman scatteri…
MgAl 2 O 4 -MgO eutectic ceramics were fabricated by the laser-heated floating zone (LFZ) method with various growth rates to assess its possible beneficial effect on microstructural aspects and mechanical properties. It was determined that the growth rate optimizing the microstructure and mechanical properties is 750…
Biological systems have evolved to create a structural and dynamic continuum of bio-macromolecular assemblies for the purpose of optimizing the system's functions. The formation of these dynamic higher-order assemblies is precisely controlled by biological cues. However, controlling the self-assembly of synthetic mole…
The thermal behavior of microelectronic devices is an important gage of their electrical performance, and can also serve as a sensitive early indicator of the onset of failure, whether spatially or temporally. In this work, we set out to report on the thermal performance of edge-terminated, vertical geometry, Ga 2 O 3…
Poplar leaves graphene (PLG) was synthesized from the poplar leaves. Modified poplar leaves graphene (M-PLG) was obtained by graphene treated with silane coupling agent γ-aminopropyltriethoxysilane (KH550). The M-PLG-modified silicone rubber (methyl ethylene silicon rubber [MVQ]) composites were prepared by mechanical…
The influence of carbon nanotubes (CNTs) in antiferroelectric liquid crystals (AFLCs) is studied using Landau phenomenological theory. A Landau model is developed to describe the effect of CNTs in the mixture of nematic liquid crystal and AFLCs. The effects of CNTs on the AFLCS and the isotropic to chiral smectic-A* (…

The atomistic stress state at a metal grain boundary is an intrinsic attribute which affects many physical and mechanical properties of the metal. While the virial stress is an accepted measure of the atomistic stress in molecular dynamics simulations, an equivalent definition is not well-established for quantum-mecha…
A thiourea-detecting fluorescence sensor with Hg2+ as a switch was developed using nitrogen-doped graphene quantum dots (N-GQDs). The surface of N-GQDs had many organic functional groups on which Hg2+ was effectively bound and turned off the fluorescence of the N-GQDs. The fluorescence of N-GQDs was turned on by the t…
Background: In this article, we have studied the effect of cellulose fibers ratio on the fiber matrix interface damage of biocomposite materials based on a Polypropylene (PP) matrix. Methods: Few patents on the effect of cellulose fibers ratio on the fiber-matrix interface damage of biocomposite materials were publish…
