Al-brass alloys (Cu29.5Zn2.5Al wt. %) were produced by gravity casting and homogenized at 800?C for 2 h, resulting in a binary phase morphology identified as cubic ? and martensitic ?? phases through X-ray diffraction (XRD). Samples were then subsequently cold rolled and annealed at 150, 300, 400, and 600?C for 30 min…
This paper reports on the first ab initio molecular dynamics study of the ferroelectric sodium nitrite, shedding light on its ferroelctric-paraelectric phase transition. The remnant polarization ${P}_{r}$ was calculated using a Mulliken population analysis and maximally localized Wannier functions. Especially the Wann…
This book illustrates a few exemplary scientific topics addressed through the use of two complementary x-ray scattering techniques: inelastic x-ray scattering and x-ray powder diffraction. These scattering methods are the focus of the two main sections of this book. These sections are subdivided into chapters discussi…
Abstract Two-dimensional (2D) materials have emerged as the ideal candidates for many applications, including nanoelectronics, low-power devices, and sensors. Several 2D materials have been shown to possess large Seebeck coefficients, thus making them suitable for thermoelectric (TE) energy conversion. Whether even hi…
Optical responses of plasmonic nanostructures can be tailor-made by judiciously controlling their structural parameters. Here in this article, we describe how symmetry-breaking influences the optical properties of an anisotropic hollow nanostructure, a hollow gold nanoprism (HGN). We find that the introduction of stru…
Gas adsorption of periodic mesoporous organosilica (PMO) containing bipyridine ligands within the framework (BPy-PMO) has been studied by in situ gas adsorption powder X-ray diffraction (XRD) analysis. Both Ar and CO 2 molecules showed strong affinity with organic moiety than silica during monolayer adsorption, even t…
An attempt has been made to compare the properties of Eli-Twist yarn with Siro yarn. Three yarns with three selectivecompositions using cotton and polyester are produced on both Eli-Twist and Siro spinning systems. Yarns of three counts(39.4, 29.5 and 23.6 tex) from each composition have been produced maintaining 4.2…
Growth and characterization of nonlinear optical (NLO) crystal of (((4-aminophenyl)sulphonyl)oxy)zinc(II)chloride (4-ASZC), based on zinc chloride with sulphanilic acid by the slow evaporation method has been studied and reported in this paper. The single crystal X-ray diffraction study confirmed the monoclinic system…
In this work, hierarchical three-dimensional (3D) urchinlike WO3 microspheres with a self-assembled nanorod core, and a connected and quasiconnected nanothorn network shell were synthesized with the hydrothermal method. For the surface or near-surface regions of pseudocapacitive materials that are involved in the Fara…
Abstract Several 238Pu-doped Eu monazite single crystals stored at ambient conditions are monitored for 15 years using Scanning and Transmission electron microscopy, spectroscopy, diffraction and optical microscopy. Despite preservation of high crystalline quality, mechanical cracking and formation of small flakes is…
Acoustic illusion devices present a novel approach for defeating detection systems such as sonar by misrepresenting information about the target. These devices are currently designed for a predetermined illusion using metamaterials. We present the first active acoustic illusion utilizing monopole control sources and e…
We examine the ordering behavior of hard platelike particles in a very narrow, slitlike pore using the Parsons-Lee density functional theory and the restricted orientation approximation. We observe that the plates are orientationally ordered and align perpendicularly (face-on) to the walls at low densities, a first-or…
Spin-gapless semiconductors (SGSs) with Dirac-like band crossings may exhibit massless fermions and dissipationless transport properties. In this study, by applying the density functional theory, novel multiple linear-type spin-gapless semiconducting band structures were found in a synthesized R 3 − c -type bulk PdF3…
Spin-coating was evaluated as a technique to study events that occur during polydopamine (PDA) thin-film formation. The reaction variants studied included type of oxidant, dopamine (DA) concentration, pH, adhesion time prior to spin, substrate chemistry, and notably, DA solution aging time. A strong oxidant, sodium pe…
Recent investigations disclose that semiconductor–ionic conductor materials (SIMs) as novel functional materials deliver superior ionic conductivity. However, SIMs are not utilized as electrolyte membranes in traditional fuel cells due to mixed ion–electron conduction. To address this issue, a Schottky fuel cell using…
Abstract The development of new optical materials and metamaterials has seen a natural progression toward both nanoscale geometries and dynamic performance. The development of these materials, such as optical metasurfaces which impart discrete, spatially dependent phase shifts on incident light, often benefits from th…
Optimum cooling of conventional thermoelectric (TE) devices is limited to about ⅙ Carnot efficiency for TE materials with figure of merit, ZT ≈ 1. This is ¼ to ½ the efficiency of typical two‐phase refrigeration systems and limits the use of TE materials to specialized applications where a combination of small size, s…
Zinc oxide nanoparticles (ZnO NPs) have a wide range of applications, but the number of reports on ZnO NP-associated toxicity has grown rapidly in recent years. However, studies that elucidate the underlying mechanisms for ZnO NP-induced toxicity are scanty. We determined the toxicity profiles of ZnO NPs using both in…
N‐doped Cu 4 O 3 thin films are deposited by radio frequency magnetron sputtering in an ambient of Ar, O 2 , and N 2 using a pure Cu target. The structural, electrical, and optical properties are investigated systematically with the variation of N 2 gas flow during deposition. Results reveal that N 2 flow rate has a s…
A viscous suspension of negatively buoyant particles released into a wide, open channel on an incline will stratify in the normal direction as it flows. We model the early dynamics of this stratification under the effects of sedimentation and shear-induced migration. Prior work focuses on the behaviour after equilibra…
