Metal borohydrides are a fascinating and continuously expanding class of materials, showing promising applications within many different fields of research. This study presents 17 derivatives of the hydrogen-rich ammonium borohydride, NH 4 BH 4, which all exhibit high gravimetric hydrogen densities (>9.2 wt % of H 2 )…
Abstract Present day's global issues focus on solutions to global warming using environment‐friendly biodegradable materials as an alternate to reduce the depletion rate of fossil materials. As the research literature encourages alternate materials for plastics, in composite material formation, this work envisages the…
In this work, the microstructure and deformation mechanism, based on uniaxial tensile tests of 2507 super duplex stainless steel, is investigated using OM, XRD, EBSD, TEM and micro-Vickers. The experimental results indicate that the as-received sheet is not sensitive to strain rate at room temperature. The ferrite pha…
Most of the polymers used as biomaterials for scaffolds are naturally occurring, synthetic biodegradable, and synthetic non-biodegradable polymers. Since synthetic polymers can be adapted for obtaining singular desired characteristics by applying various fabrication techniques, their use has increased in the biomedica…
The compound Sr(H2PO4)2·H2O has been synthesized and studied by single crystal X-ray diffraction analysis, infrared and Raman vibrational spectroscopy and density functional theory calculations. This compound crystallizes in the triclinic centrosymmetric space group P-1(Z = 2) with a = 5.7641(4) Å, b = 6.4549(4) Å, c…
In this work, we have designed a magnetoluminescent nanocomposite as a single platform for optical imaging and safe magnetic hyperthermia therapy by optimizing the composition of magnetic nanoparticles and controlling the conjugation strategy of the luminescent lanthanide complex. We have synthesized Co x Mn 1– x Fe 2…
The effect of nanosilicates on the performance of natural rubber latex (NRL)-based adhesives was studied. For comparison, a reference filler (Kaolin clay) was included in the study. Natural leather was used as the adherend and the adhesive strength was recorded by measuring the peel strength. The results indicated tha…
Defect-mediated nonradiative recombination in traditional semiconductors, such as porous graphene, tremendously lowers the fluorescence emission, thus greatly restricting their applications in more extensive fields. Here, we report that the fluorescence emission of porous graphene with a high defect density has a gian…
Abstract
The effect of deuterium (D) on the annealing of radiation damage was studied. Tungsten (W) samples were sequentially irradiated with 20 MeV W ions at room temperature and loaded with a low-temperature D plasma at 370 K to decorate the created defects. After this, half of each sample was W irradiated at room temperatur…
The acoustic emission (AE) technique is widely used at the present time for almost any kind of material characterization. The main aim of the present study was to predict the tensile strength of wool by using artificial neural networks and multiple linear regression analysis based on AE detection. With this aim, a num…
MoS 2 is a promising candidate for hydrogen evolution reaction (HER), while its active sites are mainly distributed on the edge sites rather than the basal plane sites. Herein, a strategy to overcome the inertness of the MoS 2 basal surface and achieve high HER activity by combining single-boron catalyst and compressi…
Strong inversion at the poly(3,4-ethylenedioxythiophene): polystyrene sulfonate PEDOT:PSS/silicon interface facilitates the separation of excess carriers and obstructs surface recombination, both are of utmost importance for optoelectronic detectors. In this view, low-temperature solution-processed PEDOT:PSS/silicon h…
Abstract We study the 2 × 2 charge density wave (CDW) in epitaxially-grown monolayer TiSe 2 . Our temperature-dependent angle-resolved photoemission spectroscopy measurements indicate a strong-coupling instability, but reveal how not all states couple equally to the symmetry-breaking distortion, with an electron pocke…
Switching processes of voltage source converters can emit significant high-frequency distortions of frequencies between 5 to 20 kHz. Furthermore, the distortions can partly propagate from the place of their origin into a medium voltage system via capacitive coupling of power transformers. The origin, parameters, and p…
Vertically aligned carbon nanotube (VA-CNT) arrays were grown on several chromium (Cr)-coated glass substrates using a plasma-enhanced chemical vapor deposition system. The CNTs were 2μm long and had a site density of 2×10^{9}cm^{-2} on the substrates. Two VA-CNT slides on Cr glass substrates were put together to desi…
In this article, the free torsional vibration of the noncircular microwire is obtained via modified couple stress theory. The noncircular cross section is considered to be equilateral triangle. The governing equations are derived using Hamilton’s principle, and the natural frequencies of the clamped-clamped and clampe…
Integration of multiple functionalities into a single, planar, and ultra-compact device has become an emerging research area in photonics. In this work, we design, fabricate, and experimentally demonstrate a trifunctional metasurface integrated by meta-atoms with resonant and geometrical phase cells. By changing the p…
Abstract Graphene is a very promising material platform for the mitigation of supersonic and hypersonic impacts due to its capability to delocalize impact energy at an exceptionally rapid rate. However, the intrinsic dynamic characteristics of graphene have not been quantified due to the coupling of aerodynamic effect…
Abstract Cu2O cubes, octahedra, and rhombic dodecahedra have been shown to exhibit continuous light absorption and emission band shifts with increasing particle sizes from 10 nm to sub‐microcrystals. They also possess clear facet‐dependent optical properties. Ag3PO4, Ag2O, SrTiO3, and CeO2 crystals show similar optica…
