I study the dimension-dependent (such as quantum well (QWs), quantum well wires (QWWs) and quantum dots (QDs)) transport in different nano-structures and the derivation of the expressions of many important transport coefficients are based on the temperature dependent electron concentration in nonlinear optical and opt…
In this paper, AZ61 magnesium alloy composites containing nanoalumina and micron-sized copper particulates are synthesized using the technique of disintegrated melt deposition followed by hot extrusion. The simultaneous addition of nano-Al2O3 and copper particulates led to an overall improvement in both microstructura…
In order to enhance the surface properties of P110 oil casing tube steel and increase its usage during operation, chromium coating was fabricated by pack cementation. Scanning electron microscope, energy dispersive spectrometry and X-ray diffraction were used to investigate the surface morphology, cross-sectional micr…
Abstract Cu2ZnSnSe4 ingot was synthesized and then used as a precursor for selenization process in order to fabricate Cu2ZnSnSe4 thin films. The thin films were prepared at each point A‐F in our selenization process and their properties were investigated. Cu2ZnSnSe4 ingot and thin films had a kesterite Cu2ZnSnSe4 stru…
Er3+/Yb3+ co-doped BaMoO4 (BaMoO4:Er3+/Yb3+) composites with superparamagnetic iron oxide nanoparticles (SPIONs) incorporated were successfully synthesized by a cyclic microwave-assisted metathetic (MAM) method followed by heat-treatment. The microstructure exhibited well-defined and homogeneous morphology with the Ba…
The methionine salvage pathway (MSP) recycles reduced sulfur from 5-methylthioribose. Here we propose a novel ribose metabolic pathway performed by MSP enzymes of Bacilli. MtnK, an initial catalyst of MSP, had significant ribose kinase activity, with Vmax and Km values of 2.9 µmol min(-1) mg of protein(-1) and 4.8 mM.…
Abstract Polymeric scale inhibitors are widely used in the oil and gas field because of their better thermal stability and improved environmental compatibility. However, the squeeze performance of such inhibitors is typically poorer than that of the phosphonates type scale inhibitors in conventional squeeze treatment.…
We propose a localized surface plasmon microscope that provides simultaneous imaging of refractive index and fluorescent intensity distributions. We show experimental images of fluorescent and transparent particles under circular pupil illumination to confirm simultaneous high-resolution imaging. Furthermore, we inves…
Flashover corresponds to the differential charging neutralization of dielectric parts on satellite surfaces when an electrostatic discharge (ESD) is triggered. In solar panels, it is supposed to have effects on solar cells aging and secondary arc occurrence. Laboratory experiments show that flashover propagation somet…
We used coherent anti-Stokes scattering (CAS) to characterize individual gold nanorods (GNRs) and GNR aggregates. By creating samples with different densities of GNRs on silicon wafer substrates, we were able to determine surface coverage by scanning electron microscopy (SEM) and then correlate the coverage to the CAS…
Abstract Optical constants of CdS:O window layers for solar cells were studied as a function of the oxygen content. The CdS:O thin films were deposited on glass substrates in the presence of oxygen at 0, 2, 3 and 5% values of O/Ar ratio by rf magnetron sputtering. Ellipsometric measurements on CdS:O thin films were ca…
Graphene oxide (GO) can serve as the enzyme modulator to regulate the peroxidase-like activity of the Au nanoclusters (AuNCs), as reported by Xiaogang Qu, Jinsong Ren, and co-workers on page 2594. The most exciting feature of the GO-AuNCs hybrid is that it exhibits high catalytic activity over a broad pH range, and ev…
Abstract Cu2ZnSn(S1−x,Sex)4 (CZTSSe) solid solution films were prepared on Ti foils by means of non‐vacuum, instantaneous, direct synthesis from elemental Cu, Zn, Sn, S, and Se precursor films using microwave irradiation. XRD patterns and Raman scattering spectra show that the resulting films consist of CZTSe crystals…
ABSTRACT Random styrene‐isoprene‐butadiene rubber (SIBR) were achieved with the catalyst system composed of neodymium isopropoxide (Nd(OiPr)3), methylaluminoxane (MAO) and indene. This catalyst proved to be highly effective in cyclohexane even at low [Al]/[Nd] ratio (ca. 50) to give styrene‐rich terpolymer with high n…
A new star-shaped oligoelectrolyte (TEFCOONa) with triphenylamine as the core, acetylene as linkage and anionic fluorenes as arms was obtained and used for direct imaging in living PANC-1 cells. Because of the hydrophobic conjugated groups of the oligoelectrolyte, TEFCOONa can form nanospheres with an average diameter…
Abstract Non‐doped and Ga‐doped ZnO film on glass substrate were successfully grown at 150 °C by conventional atmospheric spray pyrolysis using diethylzinc‐based solution. The samples had an average optical transmittance of more than 80% and were strongly a‐axis orientated according to the results of optical transmitt…
An unprecedented, positional effect of the isomeric repeat unit on chain folding in donor–acceptor-linked oligomers, which contain alternating bipyridine and carbazole moieties that are connected through an acetylinic linkage, is reported. 4,4′-Linked oligomer 1 adopts an intrachain helical conformation (CD-active) in…
Abstract Cu(In,Ga)Se2 (CIGS) thin films were deposited on the Mo/heat‐resistant glasses (SS‐8, Nippon Electric Glass) by the three‐stage evaporation process. The coefficient of thermal expansion (CTE) of SS‐8 is 8.4×10–6/K, strain point of SS‐8 is 582 °C. SS‐8 has the CTE similar to that of SLG but higher thermal tole…
ABSTRACT The effective fabrication of polar crystalline structures of poly (vinylidene fluoride) (PVDF), such as beta and gamma, is crucial to the development of piezoelectric polymer devices. In this study, we report the effect of pressure on binary fullerene C70/PVDF‐based composite with an overall good C70 dispersi…
Fully combined metal-oxide-semiconductor compatible light-emitting devices based on nano bi-layer structures are fabricated. The active layers are composed of silicon nitride on top of a silicon-enriched silicon dioxide film with different Si concentrations. Electro and photo luminescence spectra of the devices and th…
