Inspired by the controversy over tensile deformation modes of single-crystalline 〈110〉/{111} Au nanowires, we investigated the dependency of the deformation mode on diameters of nanowires using the molecular dynamics technique. A new criterion for assessing the preferred deformation mode—slip or twin propagation—of na…
Using Hg2Cl2, MoO3, and TeO2 (or SeO2) as starting materials, four new mixed-metal tellurites and selenites have been obtained in the unexplored mercury(I)–Mo6+–Se4+/Te4+–O system, namely, Hg2MoSeO6 (1), α-Hg2MoTeO6 (2), β-Hg2MoTeO6 (3), and Hg2Mo2TeO9 (4). They represent the first mercury(I) tellurites and selenites…
The handle properties of knitted wool fabrics were investigated using the Wool HandleMeter. The fabrics were single jersey knitted with three different loop lengths, where the yarn linear density was kept constant. The effect of a treatment using a continuous plasma treatment device was compared with untreated fabrics…
The paper deals with an efficient and accurate circuit-oriented model of multilayer graphene sheet in finite-element method (FEM) by impedance network boundary conditions (INBCs). The INBCs have been developed in the past to model efficiently the field penetration through thin conductive shields. Here, INBCs are used…
Fluorescence spectroscopy is in many ways the ideal tool for the interrogation of complex biological systems, as it is non-invasive, sensitive, and offers high spatiotemporal resolution. For biomedical imaging luminescent probes absorbing and emitting in the red-to-near infrared (NIR) region are best suited to maximis…
In this research, roasting temperature at 400C and sulphuric acid concentration variations was conducted to obtain titanium dioxide from zircon sand. The research was done through extraction metallurgy method which involved physical, chemical, and mechanical treatments. Zircon was magnetically separated, mixed with Na…
Chitosan-silver nanoparticles (CS-AgNP’s) composite films have been synthesized by three different methods. Structure and relaxation properties of nanocomposites films have been analyzed by scanning electron microscopy, thermo-gravimetry analysis, infrared, dielectric spectroscopy and X-ray photoelectron spe…
We summarize the nonlinear optical (NLO) properties of octupolar molecules, crystals, and films developed in our laboratory. We present the design strategy, structure-property relationship, and second-order NLO properties of 1,3,5-trinitro- and 1,3,5-tricyano-2,4,6-tris(p-diethylaminostyryl)benzene (TTB) derivatives,…
We present a computational study of the folding of the Trp-rich β-hairpin TrpZip2 near graphene, a surface of interest as a platform for biosensors. The protein adsorbs to the surface, populating a new bound, folded state, coexisting with extended, adsorbed conformations. Adsorption and folding are modulated by direct…
Pt overlayer on 3d transition metals show promising properties for NO oxidation.
Porous silicon nitride ceramics with various porosities were fabricated by liquid phase sintering of mixtures containing fibrous and equiaxed α‐ Si 3 N 4 powder with a various content ratios. The effects of the contents of the fibrous α‐ Si 3 N 4 powder (0%–100%) on the microstructure and mechanical properties of poro…
The article highlights the ultrasonication-assisted and diethanol fatty amide of castor oil (DEFA)-mediated bioreduction of silver (Ag) acetate in the presence of multiwalled carbon nanotubes (MWCNT) by a facile and environmentally benign “single-step one-pot approach”. DEFA was used to impart a “green capping” attrib…
We demonstrate a liquid crystal (LC) microlens array (MLA) fabricated by LCs possessing negative dielectric anisotropy, in conjunction with a cell with a three-electrode structure. The presented LC MLA is polarization-insensitive and can be operated in both concave and convex modes. The shortest focal length of the LC…
Sterically congested o-terphenyl crown ethers with alkoxy substituents at the 2,3,4-position or 3,4,5-position were synthesized from the corresponding tetrabromodibenzo[15]crown-5 and the corresponding boronic acids or borolanes via Suzuki cross-coupling and subsequently cyclized to the corresponding triphenylenes uti…
Three new organic semiconductors, in which either two methoxy units are directly linked to a dibenzotetrathiafulvalene (DB-TTF) central core and a 2,1,3-chalcogendiazole is fused on the one side, or four methoxy groups are linked to the DB-TTF, have been synthesised as active materials for organic field-effect transis…
meso-meso-Linked porphyrin arrays and meso-aryl-substituted expanded porphyrins have continuously fueled my imagination for many years. In this account, my expertise in chemical research is retrospectively summarized with a particular focus on how these two novel categories of porphyrinoids were found by our group. As…
Electromagnetic properties of Permendur (Fe50Co50 alloy) granular composite materials containing flaky particle have been studied from the RF to microwave frequency range. Properties of the flaky particle composites were compared with the spherical particle ones. The electrical conductivity of the flaky particle compo…
In this paper, windmill-shaped planar structure arrays operating in the mid-IR regime are proposed. Strong chiral dichroism of windmill-shaped planar structure is obtained numerically. The dependence of spectral characteristics on the geometrical parameters of the windmill-shaped planar structure is analyzed by the fi…
Polyurethanes are versatile materials used widely in many applications. Annual production of polyurethanes is increasing day by day. The most important application of polyurethane covering its major market is polyurethane foam. Flexible and rigid foams are two major types of polyurethane foam used widely. Flexible and…
Mg alloys are attractive candidate materials for biodegradable stents. However, there are few commercially available Mg-based stents in clinical use because Mg alloys generally undergo rapid localized corrosion in the body. In this study, we report a new surface coating for Mg alloy AZ31 based on a low-toxicity ionic…
