Abstract Hot torsion is frequently employed to simulate multipass thermomechanical rolling. While flow behavior, observed through shear stress versus shear strain, is typically used to characterize hot deformation and softening behaviors, the resulting microstructures can also provide significant insight into microstr…
The properties of large grain cuprous oxide (Cu2O) foils are explored after the implementation of a controlled postgrowth annealing process. P-type foils with a wide range of carrier density are demonstrated, enabling a promising processing window for wide bandgap solar cell devices. Hall measurements at room temperat…
Abstract The front cover artwork is provided by Dr. Tuhina Adit Maark (current affiliation: IIT Madras, India). The image shows that upon doping with transition metals the high‐pressure phases β‐ and γ‐MgH2 desorb H2 at a lower temperature than the pure hydrides. The released H2 is used in turn as a fuel for powering…
There is no doubt that for many critical applications of polymers, reinforcing agents will produce dramatic improvements of mechanical and other physical properties [1-3], such as tensile strength and flexural modulus. In this chapter, work on the effects on physical properties of several types of reinforcing agents i…
The crystal structure of solifenacin hydrogen succinate [C 23 H 27 N 2 O 2 (HC 4 H 4 O 4 )] has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional techniques. Solifenacin hydrogen succinate crystallizes in space group P 2 1 (#4) with a = 6.477 03(2), b = 7.8…
The data of experimental studies on determining the mechanical properties of long-length deformed semifinished products in a form of bars and wire made of alloys of aluminum with rare-earth metals, which are fabricated using the combined treatment methods, are presented. The application of the combined technology of c…
Rheological properties of polycrystalline iridium of I 99.9 brand are investigated in order to construct the dependence of deformation resistance on studied factors (strain ratio, rate, and temperature). The tests of cylindrical samples made of iridium are performed using a cam plastometer in temperature range t = 900…
The superheating that usually occurs when a solid is melted by volumetric heating can produce irregular solid–liquid interfaces. Such interfaces can be visualised in ice, where they are sometimes known as Tyndall stars. This paper describes some of the experimental observations of Tyndall stars and a mathematical mode…
Today manufacturing companies need to raise their awareness about emissions (e.g. CO2 equivalents) and their origins within a manufacturing system. The identification of origins of emissions becomes progressively difficult because of the customer and competition driven increase in product and process variants and the…
Amorphous thin-film Si–B–C–(N) coatings are fabricated by magnetron sputtering of sintered Si–B–C targets. The coating structure is investigated using X-ray phase analysis, scanning and transmission electron microscopy, scanning probe microscopy, glow-discharge optical emission spectroscopy, and Raman spectroscopy. Me…
Chalcogenide films can be used in thin-film solar cells due to their high photoelectric conversion efficiencies. It was difficult to identify one abnormal phase with high X-ray diffraction (XRD) intensity and preferred orientation in the samples for preparing chalcogenide films by spin-coating and co-reduction on soda…
Fibers are present in nature for millennia and are common materials in our dayto-day lives. The spider web is one typical example, showing in the simplicity of its very light 1D geometry its high degree of multifunctionality. It is designed to catch insects but also possesses extraordinary exibility and toughness allo…
Passive optical elements can play key roles in photonic applications such as plasmonic integrated circuits. Here we experimentally demonstrate passive gap-plasmon focusing and routing in two-dimensions. This is accomplished using a high numerical-aperture metal-dielectric-metal lens incorporated into a planar-waveguid…
In this paper, we have electrodeposited copper on polypyrrole surface. Results show that at high applied cathodic potential ([Formula: see text][Formula: see text][Formula: see text]1.8[Formula: see text]V), copper electrodeposition occurs with difficulties. The amount of electrodeposited copper is low (1.32%) and it…
The FT-IR Vibrational spectra analysis, electronic structures and properties of the anti-inflammatory drugs Aspirin and Ibuprofen in gas and water and ethanol have been studied by using ab initio and DFT computational calculation. The present investigation deals with the analysis of structural and bonding features res…
A new type of Cy5-encapsulated photostable fluorescent silica nanoparticles (FSNPs) bearing positive charges have been successfully fabricated by a reverse microemulsion synthesis in one-pot. The Cy5 dye containing four primary amines are embedded into silica via covalent bonds through a silane coupling agent (GPTMS),…
Magnetoresistance effects observed in ferromagnet/superconductor (FM/SC) hybrids, FM/SC bilayers (BLs) and FM/SC/FM trilayers (TLs), have attracted much interest. Here, we focus on the stray-fields-based superconducting magnetoresistance effect (sMRE) observed in Co(dCo)/Nb(dNb)/Co(dCo) TLs with sufficiently thick Co…

In this nano era, biomaterials associated infection is a serious problem in the biomedical arena. The race between microbial adhesion and tissue integration becomes a major cause of concern, during the implantation process. Microbial adhesion further gives rise to biofilm formation which finally leads to implant failu…
