Nanoparticles, nanospheres and nanorods of Y(OH) 3 and Y 2 O 3 were prepared via cathodic electrodeposition from chloride bath through applying different current densities. First, yttrium hydroxide precursors were cathodically grown on the cathode surface at the current densities of 2, 1, 0.5, 0.25 and 0.1 mA cm −2 .…
The magnetic and magneto-optical properties as well as the surface morphology and structure of La 0.7 Sr 0.3 MnO 3 polycrystalline films of different thicknesses have been investigated. It has been shown that films have a rough surface with a characteristic in-plane linear dimension of ∼30 nm, and crystallites with li…
In this study, we synthesized poly(ethylene oxide-b-L-lactide) (PEO-PLLA) diblock copolymers and poly(ethylene-b-ethylene oxide-b-L-lactide) (PE-PEO-PLLA) triblock terpolymers as templates for the preparation of mesoporous lamellar silicas, possessing single, bimodal, or trimodal pore size distributions, through an ev…
The present study reports a rapid plant-based biosynthesis of silver nanoparticles using callus extract of Jatropha curcas L. The particle size and morphological analyses were carried out using Zetasizer, SEM, TEM. The physicochemical properties were monitored using UV-Vis spectroscopic, IR and DSC. The formation of s…
Single-standard wireless transceivers are of limited use as multi-mode devices become ubiquitous. Adaptive and reconfigurable RF circuits are necessary to decrease size, cost, and power consumption as well as increase reliability and robustness of wireless devices. In this paper, the design, fabrication, and performan…
Piezoresponse force microscopy is demonstrated at temperatures between -80 °C and +120 °C using a commercial room temperature atomic force microscope upgraded with a home-built cooling/heating-stage. We applied temperature-ramp-synchronized piezoresponse force microscope (PFM) for tracing the temperature dependence of…
Nanosized particles of AFe2O4 compounds (A = Mn, Fe, Co, Ni, Zn) with spinel structure have been synthesized by precipitation from glycol solutions. Diethylene glycol (DEG) was used as high-boiling alcohol medium. Based on NMR studies, the peculiarities of the formation of nanoparticles in glycol solution using metal…
In this letter we investigate the thermo-elastic mismatch in lanthanum strontium cobalt ferrite (La0.6Sr0.4Co0.2Fe0.8O3−δ) (LSCF) films deposited onto yttria stabilized zirconia (YSZ) substrates, applicable to solid oxide fuel cells. We investigated composite LSCF+YSZ and pure LSCF films deposited onto commercial YSZ…
The fabrication of gallium oxide nanodots for the application of resistive random access memory (RRAM) using a process of atomic force microscopy (AFM) local anodic oxidation on an indium tin oxide conductive glass substrate is reported. In the atmospheric environment, an AFM probe tip contacts the gallium film locall…
The characteristic features of thermal expansion of bulk samples of niobium diselenide have been determined experimentally and analyzed theoretically. The manifestation of the so-called membrane effect in this compound due to the significant difference in the temperature dependences of the mean-square amplitudes of at…
The composition of a glass former alloy and the cooling rate are both extremely important to determine the maximum glassy or critical thickness of a sample under a specific processing technique. This work compares the suction casting and the centrifugal casting techniques for processing two Cu–Zr–Al bulk metallic glas…

Debris with footprints smaller than 40 μm2 on the outer and inner surfaces with heights of <10 μm on outer surfaces and [approximately]1 μm on inner surfaces is present on cryogenic targets used for inertial confinement fusion studies on OMEGA. These features form during the gas-filling and cooling processes used to p…
Composites are widely used in all the fields because of its favorable properties over conventional materials. Medium Density Fiberboard (MDF) is an extensively used wood composite in furniture industries. Drilling is the most commonly used machining process in the assembly. The surface quality of the hole depends upon…

Abstract A novel triangle-shaped macrocyclic complex, [(tmeda)Pt(azpy)]3(PF6)6·13H2O (tmeda: tetramethylethylenediamine, azpy: 4,4′-azopyridine) has been successfully synthesized via self-assembly of [(tmeda)PtCl2] with a bulky capping ligand, tmeda and flexible organic linker, azpy. 1H NMR results show the realizatio…
Affinity partitioning in aqueous two phase extraction is a single step purification process in downstream processing. Integrating metal ligands to the phase forming polymers in aqueous phase extraction known as ATPi ensures high selectivity and also promises good partition. In the present work, the effect of metal lig…
