Recently, it was reported that the skutterudite-related ${\mathrm{Ce}}_{3}{\mathrm{Rh}}_{4}{\mathrm{Sn}}_{13}$ heavy fermion compound has a large electronic specific heat coefficient $C(T)/T$ and short-range magnetic correlations, both suggest a possible quantum critical point (QCP). We present the low-temperature spe…
A self-assembled quantum dots array (QDA) is a low dimensional electron system applied to various quantum devices. This QDA, if embedded in a single crystal matrix, could be advantageous for quantum information science and technology. However, the quantum tunneling effect has been difficult to observe around room temp…
This Letter describes a double-sided process to fabricate freestanding membrane devices on a GaN-on-silicon platform. The photoluminescence measurement is taken to characterize the optical performance. A large portion of the excited light from InGaN/GaN multiple quantum wells is trapped as waveguide modes and propagat…
We have fabricated Transition Edge Sensors (TESs) whose thermal characteristics are completely characterised by few-mode ballistic phonon exchange with the heat bath. These TESs have exceptionally small amorphous SiNx support legs: 0.2 μm thick, 0.7–1.0 μm wide, and 1.0 to 4.0 μm long. We show, using classical elastic…
Abstract The design and plantwide control of an integrated plant, where the endothermic dehydrogenation of 1,4‐butanediol leading to γ‐butyrolactone and the exothermic hydrogenation of furfural leading to furfural alcohol and 2‐methyl furan are simultaneously performed in a single reactor, is presented. Analysis of th…
In the paper, an environmentally friendly and template-free route based on a simple hydrothermal process has been developed for preparing rattle-type TiO2 hollow microspheres by using titanium(IV) sulfate (Ti(SO4)2) as the titanium source and glycerol/water as the cosolvent. The SEM and TEM images showed that the obta…
Solid niobium oxides (Nb 2 O 5 · n H 2 O) and niobium phosphate were used as heterogeneous acid catalysts to promote the condensation between a switchable oxazine and a fluorescent coumarin in aprotic solvents.
We demonstrate a new kind of silicon (Si)-based anode architecture consisting of Si nanoparticles and carbon nanocoils (CNCs). In such a hybrid structure, the conductive three-dimensional interpenetrating network of the CNCs can enhance the structural integrity of the electrode. Also, the CNCs afford a conductive netw…
We have developed atomic layer deposition (ALD) methods to synthesize robust nanostructured composite coatings with tunable resistance comprised of conducting, metallic nanoparticles embedded in an amorphous dielectric matrix. These films are nominally composed of M:Al2O3 where M= W or Mo, and are prepared using alter…
The present manuscript reports the characterization, optimization of rheological properties, and loading and release capabilities of 5'-GMP mediated β-FeOOH hydrogel. Circular dichroism (CD) analysis indicates it to contain mainly the left-handed helix similar to that of Z-DNA. The highest viscosity (>300 cP) correspo…
We report the preparation, analysis, and phase transformation behavior of polymorphs and the hydrate of 4-amino-3,5-dinitrobenzamide. The compound crystallizes in four different polymorphic forms, Form I (monoclinic, P 2 1 / n ), Form II (orthorhombic, Pbca ), Form III (monoclinic, P 2 1 / c ), and Form IV (monoclinic…
To decrease the coke yield while increase the conversion of FCC feedstock is of great significance as the crude oil becoming heavier and poorer in quality. In this work, the modified mesoporous alumina with rich Brönsted acidic sites (BAS) and reduced Lewis acidic sites (LAS) have been prepared by a sol-gel method. Th…
Designed armadillo repeat proteins (dArmRP) are promising modular proteins for the engineering of binding molecules that recognize extended polypeptide chains. We determined the structure of a dArmRP containing five internal repeats and 3rd generation capping repeats in three different states by X-ray crystallography:…
The modification of commercial ultra-stable Y (USY) zeolite using citric acid (CA) and ammonium fluosilicate (AFS) was investigated. A series of factors including the concentration of CA and AFS, the volume ratio of CA and AFS, adding rate of AFS, reaction time and temperature were studied to get the optimum operation…
Abstract The major combustion products from munitions containing nitro‐based propellants are water, carbon monoxide, carbon dioxide, hydrogen, and nitrogen. In addition, compounds including hydrogen cyanide, ammonia, methane, nitrogen oxides, benzene, acrylonitrile, toluene, furan, aromatic amines, benzopyrene, and va…
Two coaxial pellets with tungsten inserted into graphite carbon and polyethylene (PE) tubes are compared for tungsten spectroscopic study in the Large Helical Device. The tungsten pellet with carbon tube causes plasma collapse, while that with PE tube smoothly ablates without collapse. The deposition profile of the pe…
Fully relativistic first-order perturbation theory calculations are made for the electron-impact ionization of the inner $K$, $L$, and $M$ subshells of uranium. One set of calculations only includes the two-body electrostatic interaction, while the other set includes the full two-body retarded electromagnetic interact…
Interaction between the lattice and the orbital degrees of freedom not only makes rare-earth nickelates unusually ``bad metal,'' but also introduces a temperature-driven insulator-metal phase transition. Here we investigate this insulator-metal phase transition in thin films of ${\mathrm{SmNiO}}_{3}$ using the slow ti…
Zinc oxide (ZnO) nanowire based Schottky barrier diodes are fabricated by depositing Pd metal contact on top of vertically well-aligned ZnO nanowire arrays. A vertical array of ZnO nanowires on indium tin oxide (ITO) coated glass substrates is synthesized by hybrid wet chemical route. Scanning electron microscopy (SEM…
The mechanical properties of methyl vinyl silicone rubber foam materials with different cell diameters of the spherical cell structure were investigated. The results showed that the cell diameter had significant effects on the mechanical properties,the foam materials with cell diameter range 300~450μm had the best com…
