We investigated the electrocaloric (EC) effects in epitaxial Ba 0.8 Sr 0.2 TiO 3 (BSTO) thin films grown on LaAlO 3 and MgO substrates and in BSTO sol-gel thin films grown on Si substrates. We compared the EC effects in two forms of BSTO to confirm whether the giant EC effect recently observed in the polycrystalline t…
J. Chen, M. Xue, and colleagues report 3D interdigital electrodes based on reduced graphene oxide for stretchable all-solid-state supercapacitors with adjustable volumetric capacitance, which are accomplished via pressure spray printing and machine coating. The supercapacitor presented on page 4601 can remain high spe…
Abstract : This report was written by the author under the Engineer Scientist Exchange Program activity in the US Army Research Laboratory from April 2013 to September 2014. To clarify the accuracy of finite element (FE) material models for butyl rubber, the component-level loading test was conducted on drop testers i…
The short-circuit damage of a power transformer is the serious main equipment accident in power grid. Thus to reduce transformer short-circuit accident by detecting transformer winding deformation is extremely important. This paper proposes a methodology to interpret low-voltage impedance measurements of a deformed or…
In bulk samples of p-Cd1 − x Mn x GeP2, p-Cd1 − x Mn x GeAs2, and p-Zn1 − x Mn x GeAs2 at high hydrostatic pressures (P ≤ 9 GPa), the pressure dependences of the electrical resistivity and the volume change were studied. In all the studied samples, there were phase transitions accompanied by a volume jump. This sugges…
We fabricated a 0.17-μm gate-length AlGaN/GaN high electron mobility transistor (HEMT) on SiC recessed by using ICP gate etching with a gas mixture of BCl3/Cl2. The ICP gate recess process exhibited an etch rate of 20 nm/min for the AlGaN layer and the clean surface characteristics at the etched AlGaN/gate metal inter…
The microstructure, texture evolution and thermal properties of the as-cast and as-extruded Mg92Zn4Y4and Mg92Zn4Y3Gd1alloys with long period stacking ordered (LPSO) structure phases have been investigated in details. The results show that the microstructures of the as-cast and as-extruded alloys mainly consist of α-Mg…
Abstract In this study, a nanocomposite of 3, 4, 9, 10‐perylenetetracarboxylic acid and L‐cysteine (PTCA‐Cys) with satisfactory water‐solubility and film‐forming ability was prepared and worked as substrate for modifying the glassy carbon electrode. Then, gold nanoparticles (AuNPs) were immobilized to achieve a PTCA‐C…
In order to improve the salt spray corrosion resistance of the aerospace electronic products with the power MOSFET, meet the high reliability requirements, improve the packaging process of power MOSFET. This paper starts from the mechanism of packaging materials'salt spray corrosion, through the packaging materials se…
The advanced IC packaging technologies such as 3D-TSV, 2.5D interposer, PoP and Flip-Chip wafer micro-bumping are being implemented for consumer electronic products like as mobile phones, tablets, and so on. The form factor of consumer product trends toward small and thin which driving IC packaging toward smaller, thi…
We performed MD simulations of nanoindentation on a single layer graphene nanoribbon in order to obtain the tip-position-dependent mechanical properties of the graphene nanoribbon. A correlation between the load and the indentation depth was constructed. Also, the bending rigidity, the Young’s modulus and the strength…
In this study, we fabricated red phosphorescent organic light-emitting diodes (PhOLEDs) on rigid glass and flexible plastic substrates by using a trilayer-structured metal anode (Ni/interlayer metal/Ni) and analyzed the optical and the electrical characteristics of these devices. The thickness of the electron transpor…
The results of the experimental observation of the photovoltage in a SrTiO 3 crystal sample, which exhibits the light-induced resistance-drop effect, have confirmed the previously proposed model of the effect in its photoelectric part. However, in addition to the expected manifestation of the barrier photovoltage, one…
There is a need for oil casing tubes to resist both wear and corrosion attacks during operation. In the present work, a G3 alloy-like coating has been formed on P110 oil casing tube steel via double glow plasma surface alloying using a G3 alloy source electrode to improve its surface performance and prolong its servic…
Three donor acceptor chromophores were synthesized by Knoevenagel condensation. Structures of the chromophoes were conformed by the elemental analysis and EI-MS, FT-IR, 1H-NMR, 13C-NMR spectroscopy. Absorbance and fluorescence spectra of the chromophores were studied in different solvent provide that all the chromopho…

Abstract The taxonomic position of Pyxidicula compressa, currently the nomenclatural basionym of two unrelated taxa (a diatom and a dinoflagellate), is clarified. Evidence is presented that the protologue of the species clearly represents a diatom, which is then correctly known as Tryblionella compressa . In the absen…
Species constituting diatom assemblages in sediments provide important information regarding the past and present environmental conditions related to soil and water physico-chemistry and also biodiversity dynamics data. This information can reveal the developmental history of the region. Diatoms are sensitive to stoch…
