An activation process involving chitosan was conducted to prepare electroless nickel plated wood veneers for electromagnetic interference (EMI) shielding. In this process Pd(Ⅱ) ions were chemically adsorbed on wood surface modified with chitosan. Then they were reduced and dipped into a plating bath in which Ni-P co-d…
There are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (CH), adhesive systems, resin composite and glass ionomer cements. The aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for…
The Physical Optics (PO) approximation is investigated as tool for analysis of scattering problems involving coated electrically large conducting platforms. The PO-derived current is corrected by including additional terms that account for diffraction phenomena. Numerical example demonstrates usefulness and limitation…
Usage of polymers materials in microelectronics and especially in packing is nowadays common. Polymer materials are used for example in case of encapsulation, underfills for flip chip, moulding compound, electrically or thermally conductive adhesive, flexible electronics, materials for Printed Circuits Board (PCB), et…
A simple process is presented for the preparation of TiO2nanoparticles by Co-precipitation method. This process is relatively cheaper and by using different variation we can control particle size and shape. TiCl4was used as primary precursor along with Na2CO3for synthesis of Rutile nanoparticles. Synthesis was done wi…
Advances in technology have led to development of wearable sensing, computing and communication devices that can be woven into the physical environment of our daily lives, enabling a large variety of new applications in several domains including wellness and health care. Despite their tremendous potential to impact ou…
The structure parameters and eddy current field circumstance of magnetic coupling have influence on the ability of magnetic torque of the magnetic coupling, as well as the efficiency and reliability of the magnetic pump set, so it is necessary to research into the impacts of parameters of magnetic coupling on the eddy…
The kinetics of oxidation of 1-methoxy-2-propanol and 1-ethoxy-2-propanol by ditelluratocuprate(III) (DTC) in alkaline liquids has been studied spectrophotometrically in the temperature range of 293.2–313.2 K. The reaction rate showed first order dependence in DTC and fractional order with respect to 1-methoxy-2-propa…
The strength and plastic properties of amorphous wires produced by melt spinning, in-rotatingwater spinning (INROWASP), and the Taylor-Ulitovskii method are studied. The wire produced by the Taylor-Ulitovskii method is found to have the highest level of strength and plasticity. The fracture and lateral surfaces of the…
In this study, we demonstrate the fabrication of highly efficient white organic light-emitting diodes (WOLEDs) with a p–i–n tandem structure using lithium (Li)-doped tris(8-hydroxyquinoline) aluminum (Alq3)/molybdenum oxide (MoO x )-doped 4,4',4''-tris[2-naphthyl(phenyl)amino] triphenylamine (2-TNATA) as an effective…
Self-blocking of dislocations belonging to the cube plane has been detected in the intermetallic compound Ni3Ge. The nature of cubic slip has been clarified. The experiments included deformation at a temperature above T max (the temperature of the yield-stress peak) and subsequent heating without stress. In addition,…
We systematically investigated the effect of the thermal oxidation treatment on the performance of AlGaN/GaN high electron mobility transistors (HEMTs). The HEMTs with thermal oxidation treatment exhibit four orders of magnitude reduction in gate leakage current, 80% reduction of trap density, and more than two times…
The impurities sulphur, phosphorus, lead, bismuth, tin and antimony affect the hot workability of stainless steels. In this study, the authors show that sulphur and lead segregate to phase and solidification grain boundaries, where cracks appear during hot deformation. The workability was tested by the hot rolling and…
Abstract Dispersion strengthened materials belong into the group of composite materials, which are made mainly by powder metallurgy. Their structure has a polycrystalline matrix, in which dispersion particles are incorporated, mainly oxide, carbide and nitride type. The Al-C systems belong among modern materials desig…
We calculate the most probable reaction paths for thermally induced magnetization reversal of a nanomagnet under the influence of spin transfer torque. The presence of the spin transfer torque implies that the standard reaction rate theory of Kramers cannot be used since the dynamics no longer shows detailed balance a…
UNLABELLED: Establishing standards for meat tenderness based on Warner-Bratzler shear force (WBSF) is complicated by the lack of methods for certifying WBSF testing among texture systems or laboratories. The objective of this study was to determine the suitability of using gelatin gels as reference materials for perfo…
We calculated the Seebeck coefficient of heavily-doped Si based on theoretical models of impurity-band formation, ionization-energy shift and conduction-band tailing. The impurity band was described by using two kinds of band-width definitions and it was found that the calculated Seebeck coefficient strongly depended…
It is shown that instability develops on the lateral surface of viscous fingers formed when a fluid is displaced from a Hele-Shaw cell. This instability is caused by the inertia forces, whereas the viscous forces acting in the plane of the cell stabilize the surface.
A new phosphoryl-containing ligand based on 4-aminoantipyrine- N -(1,5-dimethyl-3-oxo-2-phenyl-1,2-dihydropyrazol-4-yl)- P , P -diphenylamidophosphinate (L) was synthesized. In crystals, the L molecules were found to be combined in centrosymmetric dimers through N-H…O=C hydrogen bonds. The complexes of L with neodymiu…
