Pseudo-octahedrons of Ba 2 GdF 7 were successfully synthesized through a solution-based method in a hydrothermal environment for the first time. The preferential adsorption of ethylene glycol (EG) molecules on the {111} planes contributed to the formation of the octahedral shape. Hydrazine was employed as the alkaline…
A small donor-acceptor molecule is synthesized in a two-step procedure involving reaction of N,N-diphenylhydrazine on 2,5-diformylthiophene and Knoevenagel condensation. Results of UV/Vis absorption spectroscopy and cyclic voltammetry show that replacement of the phenyl ring bridge of a reference compound 2 by an azo…
PURPOSE: Carbon-13 magnetic resonance spectroscopy ((13) C-MRS) is challenging because of the inherent low sensitivity of (13) C detection and the need for radiofrequency transmission at the (1) H frequency while receiving the (13) C signal, the latter requiring electrical decoupling of the (13) C and (1) H radiofrequ…
Forward gate-bias stress experiments are performed to investigate the variation of trap states under Schottky contact in GaN-based high electron mobility transistors. Traps with activation energy ET ranging from 0.22 eV to 0.31 eV are detected at the gate-semiconductor interface by dynamic conductance technique. Trap…
We have been examining factors determining the accuracy of cluster expansion (CE), which is used in combination with many density functional theory (DFT) calculations. With the exception of multicomponent metallic or isovalent ionic systems, the contributions of long-range effective cluster interactions (ECIs) to conf…
Poly-L-Lysine (PLL) nanocapsules are the emerging drug-delivery vehicle for the therapeutics of targeted diseases. The study was designed for the synthesis and characterization of PLL nanocapsules and to know its immunocompatibility and toxicity behavior for in vivo drug-delivery applications. Alteration in hematologi…
Three novel alkali–lanthanide heterometal–organic frameworks, namely, [K 5 Ln 5 (pztc) 5 (H 2 O) 19 ]·7H 2 O [Ln = Dy ( 1 ), Ho ( 2 ), and Yb ( 3 ); H 4 pztc = pyrazine-2,3,5,6-tetracarboxylic acid], have been facilely synthesized. X-ray crystallographic analysis reveals that complexes 1 – 3 are isostructural, featuri…
Abstract Ein enantiomerenreiner Bis(3‐pyridyl)‐Ligand 1 auf der Basis eines BINOL‐Gerüsts bildet mit tetravalenten PdII‐Ionen einen homochiralen [Pd4(1)8]‐Komplex. Zwei Tetrafluoroborationen dienen dabei als Template für die Bildung dieses Aggegates und werden in zwei periphere Kavitäten eingeschlossen. Die dadurch re…
Low-temperature photoluminescence emission spectra were measured in cadmium telluride (CdTe) samples in which composition was varied to promote either Cd or Te-rich stoichiometry. The ability to monitor stoichiometry is important, since it has been shown to impact carrier recombination. Te-rich samples show transition…
In most published papers, in order to obtain the analytical solution of the crack problems in functionally graded materials (FGMs), the thermomechanical properties of FGMs are usually assumed to be very particular functions and, hence, may not be physically realizable for many actual material combinations. Very few an…
We demonstrate the stability of the spin-triplet paired s-wave (with an admixture of extended s-wave) state for the limit of purely repulsive interactions in a degenerate two-band Hubbard model of correlated fermions. The repulsive interactions limit represents an essential extension of our previous analysis (2013 New…
Surfactant-free, H 2 -reduced Pt NPs were successfully fabricated on the surface of Fe 3 O 4 . Characterizations disclosed that Pt NPs (3.1 nm on average) dispersed evenly on Fe 3 O 4 . This catalyst is extremely active and selective for hydrogenation of chloronitrobenzenes, convenient, and suitable for cyclic utiliza…
Although much is known about protein folding in buffers, it remains unclear how the cellular protein homeostasis network functions as a system to partition client proteins between folded and functional, soluble and misfolded, and aggregated conformations. Herein, we develop small molecule folding probes that specifica…
Chemical functionalization of various hydrocarbons, such as coronene, corannulene, and so forth, shows good promise in electronics applications because of their tunable optoelectronic properties. By using quantum chemical calculations, we have investigated the changes in the corannulene buckybowl structure, which grea…
Creating uniform coatings of a solution-cast material is of central importance to a broad range of applications. Here, a robust and generic theoretical framework for calculating surface coverage by a solid film of material de-wetting a substrate is presented. Using experimental data from semiconductor thin films as an…
OBJECTIVES: The present study determined the effects of mobile phone (900 and 1800 MHz)-induced electromagnetic radiation (EMR) exposure on oxidative stress in the brain and liver as well as the element levels in growing rats from pregnancy to 6 weeks of age. METHODS: Thirty-two rats and their offspring were equally d…
Resistive-switching (RS) memories with good performance and flexibility are demonstrated in p-type amorphous CuAlOx. The nature of conducting filaments (CFs) is studied via the dependence of RS behaviors on the oxygen concentration of CuAlOx. It is observed that with increasing oxygen concentration, (1) both resistanc…
We have systematically investigated the material and electrical properties of yttrium-doped GeO2 (Y-GeO2) on Germanium (Ge). A significant improvement of both thermal stability and water resistance were demonstrated by Y-GeO2/Ge stack, compared to that of pure GeO2/Ge stack. The excellent electrical properties of Y-Ge…
This study investigates the dielectric properties of multiwalled carbon nanotube (MWCNT)/polystyrene (PS) composites over the broadband frequency range, i.e., 10−1 to 106 Hz. The results showed that the real permittivity and imaginary permittivity increased remarkably with increased MWCNT concentration. For instance,…
Silica-supported tantalum oxide (ST) hollow spheres were designed for photocatalytic applications in the UV range of 4.1 to 4.8 eV. These nanostructures with a variable diameter of 100-250 nm and shell thickness of 24-58 nm were obtained by the hydrothermal treatment of tantalum isopropoxide and tetraethylorthosilicat…
