Catalysts based on electroless nickel and bi-metallic nickel-molybdenum nanoparticles were synthesized for the hydrolysis of sodium borohydride for hydrogen generation. The catalysts were synthesized by polymer-stabilized Pd nanoparticle-catalyzation and activation of Al2O3 substrate and electroless Ni or Ni-Mo platin…
We apply quantum Monte Carlo technique to address the issue of high controllability of ferromagnetism in graphene and the issue of electron correlation driven superconductivity in graphene, by simulating the t − U − V Hubbard model on a honeycomb lattice. In the region of low electron band filling below the Van Hove s…
This work presents an understanding of orientation dependence of electronic and phononic thermal conduction in Al interfaces. Focus is on quantifying the effect of interface orientation, the effect of tensile strain, and the effect of temperature on electronic and phononic thermal conduction across examined Al interfa…
Abstract The current article reports a preparation method of nano‐petal nickel hydroxide, which was synthesized using urea as a precipitator by hydrothermal method. Nickel hydroxide samples with different micro‐structural characteristics were prepared by changing molar ratio of nickel/urea and reaction time. The prepa…
Spherical mesopores: Mesoporous Pt rods containing cage-type mesopores were prepared with porous anodic alumina membranes (PAAMs). It is noteworthy that spherical mesopores are aligned in the rods due to physical confinement by the PAAM channels. Both the mesopore alignment and the morphological control are realized s…
We investigate the effect of low temperature annealing or of extended storage at room temperature on the subsequent nucleation behavior of amorphous AgIn-incorporated Sb2Te (AIST), a material for phase change memories. Time-resolved reflectivity measurements during pulsed laser crystallization reveal the rates of soli…
The influence of composition of various solutions, applied for final treatment of Si wafers before stain‐etched porous silicon (PS) formation, on the incubation period and antireflective properties has been investigated. PS layers were obtained by chemical etching in HF:HNO3:CH3COOH modified solution at oxidant insuff…
Structural and biochemical studies of the orf12 gene product (ORF12) from the clavulanic acid (CA) biosynthesis gene cluster are described. Sequence and crystallographic analyses reveal two domains: a C-terminal penicillin-binding protein (PBP)/β-lactamase-type fold with highest structural similarity to the class A β-…
A cost-effective method for fabricating antireflective subwavelength structures on silicon carbide is demonstrated. The nanopatterning is performed in a 2-step process: aluminum deposition and reactive ion etching. The effect, of the deposited aluminum film thickness and the reactive ion etching conditions, on the ave…
OBJECTIVE: To investigate the cytotoxicity and the genotoxicity of standardized aqueous of dry leaves of Erythroxylum cuneatum (E. cuneatum) in human HepG2 and WRL68 cells. METHODS: The cytotoxicity of E. cuneatum extract was evaluated by both MTS and LDH assays. Genotoxicity study on E. cuneatum extract was assessed…
The nanoscopic magnetoelectronic phase separation in doped La${}_{1\ensuremath{-}x}$Sr${}_{x}$CoO${}_{3}$ perovskites was studied with local probes. The phase separation is directly observed by M\"ossbauer spectroscopy in the studied doping range of 0.05 $\ensuremath{\le}$ $x$ $\ensuremath{\le}$ 0.25 both at room temp…
The phase diagram of $para$-H${}_{2}$ on both one-layer and bilayer graphene was calculated by means of the diffusion Monte Carlo method. The zero-point energy of the carbon atoms in the substrate was taken into account. That inclusion had minor effects on the liquidlike or incommensurate branches of the phase diagram…
Black molybdenum oxide (BMO) is prepared by annealing transparent MoO3. While recent efforts on other black oxides show that their black colour contributes little towards visible light harvesting, the presented BMO shows much-enhanced photoresponse over the UV–vis–IR regions. By sandwiching the BMO with suitable charg…
A systematic investigation on electrical fatigue in lead zirconate titanate (PZT) is carried out for different loading frequencies. Experiments are conducted up to 106 cycles to measure the electrical displacement and longitudinal strain on bulk ceramics in the bipolar mode with large electrical loading conditions. A…
We report herein a simple strategy for fabricating two-dimensional (2D) petal-like Ni x Cd 1– x S/octadecylamine (ODA) hybrids exhibiting both photoluminescent and superhydrophobic properties via a facile liquid–liquid interfacial self-assembly technique. First, thioglycolic acid stabilized CdS quantum dots (QDs) dope…
Solvent can subtly influence the organization of supramolecular polymers.
There has been an increase in the use of fiber-reinforced composite materials in many areas. In particular, glass-fiber-reinforced composites have gained in popularity owing to their low cost, high-strength properties, durability, ease of repair, and being simple to form. This paper analyzes the buckling load for the…
Driven by conformational entropy, a shape memory polymer (SMP) is capable of memorizing typical programming information, such as level of induced strain, deformation sequence and temperature profile. Because strain rate is one of the variables during programming, it is desirable to know whether the strain rate effect…
The construction of electrochromic multilayers on textiles is described. Polyester foils are sputtered with a thin layer of translucent indium tin oxide (ITO). On these ITO layers, WO3 and polyaniline (PANI), respectively, are deposited electrochemically in a continuous process. Both the PANI- and WO3-based materials…
A new monoclinic solvate containing two molecules of the thiopeptide antibiotic thiostrepton in the asymmetric unit has been crystallized in space group P2(1). Single-crystal diffraction data to a resolution of 0.64 Å were collected at the SLS synchrotron, allowing structure solution by direct methods and resolution o…
