In this paper, a novel low-loss NiZnCo ferrite prepared by a hydrothermal method has been developed for miniaturization and performance enhancement of mobile handset antennae. XRD analysis revealed that in weakly alkaline solution, H+ ions generated in the reaction process result in an acid-alkali imbalance. In a stro…
The bulk electronic structure of ${\mathrm{NiS}}_{2\ensuremath{-}x}{\mathrm{Se}}_{x}$ has been studied across the bandwidth-control Mott transition (BCMT) using soft x-ray angle-resolved photoemission spectroscopy. We show that Se doping does not alter the Fermi surface volume. When approaching the insulating phase wi…
Shade percentage is an important factor which has various impacts on cotton knitted fabric. The technical factors GSM, CPI (Course per Inch), WPI (Wales per inch), shrinkage percentage, color fastness of cotton knitted fabric are influenced by various shade percentage. The main objective of this paper was to find out…
Various full Heusler alloys are interfaced with MgO and the magnetic properties of the Heusler-MgO junctions are studied. Next to MgO, the cubic Heusler system distorts to a tetragonal one, thereby inducing an anisotropy. The half-metallicity and nature of anisotropy (in-plane or perpendicular) in the Heusler-MgO syst…
The existence and effect of different rare earth $(R^{2+/3+/IV})$ ions in $SrAl_{2}O_{4}:Eu^{2+},R^{3+}$ and $M_{2}MgSi_{2}O_{7}:Eu^{2+},R^{3+}$ (M: Sr, Ba) persistent luminescence materials was studied with XANES (x-ray absorption near edge structure) measurements at HASYLAB/DESY (Hamburg, Germany) and MAX-lab (Lund,…
We investigate the consequences of broken translational symmetry in the superconductor ${\mathrm{FeSe}}_{x}{\mathrm{Te}}_{1\ensuremath{-}x}$ using angle-resolved photoemission spectroscopy. We find that the intensity does not follow the periodicity dictated by the crystal structure, owing to the form of the perturbing…
In this study, a new lead-free ceramic system of (1–x)Bi0.5Na0.5TiO3–0.065BaTiO3–xSrZrO3 BNBT–SZ100x (with x = 0–0.10) was prepared by a conventional solid-state reaction method and its structural and electrical properties were studied. XRD analysis revealed the formation of pure perovskite phase for all ceramics. The…
Flexible photonic crystals are attractive devices owing to their multifold tunable parameters additionally introduced by soft substrates or by nanostructured, nano-doped, or nano-embedded soft matters. This not only extends significantly the intrinsic functions of photonic crystals, but also facilitates easy integrati…
Systematic ${}^{31}$P-NMR studies on LaFe(${\text{As}}_{1\ensuremath{-}x}$${\text{P}}_{x}$)(${\text{O}}_{1\ensuremath{-}y}$${\text{F}}_{y}$) with $y=0.05$ and 0.1 have revealed that the antiferromagnetic spin fluctuations (AFMSFs) at low energies are markedly enhanced around $x=0.6$ and 0.4, respectively, and as a res…
Some highlights of the time-resolved vacuum ultraviolet (VUV) luminescence spectroscopy of solids using synchrotron radiation (SR) are outlined, including studies of the unique phenomenon crossluminescence (CL) and the contribution of time-resolved VUV spectroscopy to the understanding of 5d–4f transitions of rare ear…
Despite their useful physico-chemical properties, carbon nanotubes (CNTs) continue to cause concern over occupational and human health due to their structural similarity to asbestos. Thus, to evaluate the toxic and genotoxic effect of multi-wall carbon nanotubes (MWCNTs) on lung cells in vivo, eight-week-old rats were…
The effects of the chemical modification of peanut shell powder (PSP) using polyvinyl alcohol (PVOH) were studied. Both modified and unmodified peanut shell powder were used to prepare recycled polypropylene (RPP) and PSP composites. The effects of various PSP loadings (0 to 40% by weight) on the processing, tensile p…
Three-dimensional architectures composed of one-dimensional nanoscale building blocks are well-known to be able to integrate properties of materials with different dimensions and to derive more advanced performance. In this experiment, ZnO nanorod arrays are controlled to grow on NiO nanowires (NWs) to construct typic…
The initial stage of calcium carbonate nucleation and growth, found usually in "natural" precipitation conditions, is still not well understood. The calcium carbonate formation for moderate supersaturation level could be achieved by an original method called the fast controlled precipitation (FCP) method. FCP was coup…
Double perovskite Nd2CoMnO6 thin films have been grown epitaxially on SrTiO3 substrates using pulsed laser deposition and their structural, magnetic, and dielectric properties were investigated. Temperature dependent dielectric (ε) constant is measured in the frequency range between 1 kHz and 1 MHz under applied magne…
We report the synthesis and characterization of Pb-chalcogenide fused quantum-dot (QD) dimer structures. The resulting QD dimers range in length from 6 to 16 nm and are produced by oriented attachment of single QD monomers with diameters of 3.1-7.8 nm. QD monomers with diameters exceeding about 5 nm appear to have the…
We report on a systematic time-resolved photoluminescence study of the competing energy and charge transfer rates in PbS QDs of differing sizes in the same QD solid as a function of both temperature and ligand-controlled different inter-QD average separations. This complements previous studies that typically varied on…
The materials properties of graphene and other two‐dimensional atomic sheets are influenced by atomic‐scale defects, mechanical deformation, and microstructures. Thus, for graphene‐based applications, it is essential to uncover the roles of atomic‐scale defects and domain structures of two‐dimensional layers in charge…
Technologies that are able to handle microvolumes of liquids, such as microfluidics and liquid marbles, are attractive for applications that include miniaturized biological and chemical reactors, sensors, microactuators, and drug delivery systems. Inspired from natural fibrous envelopes, here, we present an innovative…
In this article the results of research on a continuous thermomechanical reclaiming process of ground tire rubber (GTR) conducted in a twin screw extruder are presented. The effects of the rotation direction (co-rotating/counter-rotating), design of co-rotating plasticizing units and the rotational speed of the screws…
