In this study, hydrolysis of the anticancer drug trans -bis-(3-amino-flavone)dichloridoplatinum(II) ( trans - Pt(3-af) 2 Cl 2 ; TCAP) in gas and solution phases is studied. With the polarizable continuum model (PCM) model the complex computational study is performed in an aqueous solvent. Before the complex interactio…
In article number 1801954, Wallace C.H. Choy and co-workers reveal the thermionic-emission assisted electron transport mechanism theoretically and experimentally in a novel interconnecting structure of perovskite-perovskite tandem solar cells. This interconnecting layer features solvent-resistance, is free of indium t…
Abstract— Boehmite gel was prepared via hydrolysis of aluminum isopropylate in a water–alcohol solution. Electron-microscopic examination showed that the boehmite particles were highly uniform in diameter, at ~70 nm. X-ray fluorescence analysis demonstrated high purity of the material. The boehmite was heat-treated in…
The measurement of transient temperatures less than 1000 K for samples in laser-heated diamond anvil cells remains a challenge. Here we present the design and performance characteristics of a multi-channel pyrometer that works in the near-infrared from 1200 to 2000 nm. It has a relatively small footprint, is portable,…
Abstract Laminated paperboard is one of the main materials used in packaging products. The technical processes used for manufacturing such materials lead to a sepcial fiber structure that gives the material anisotropic behavior which can be observed in experiments. Two different directions can be distinguished;the in‐…
We researched the relation between deposition and ultra-thin VN films parameters. To conduct the experimental study we varied substrate temperature, Ar and N 2 partial pressures and deposition rate. The study allowed us to obtain the films with close to the bulk values transition temperatures and implement such sample…
Abstract Herein, a finite strain microscale model for magnetorheological elastomers with magnetically hard fillers is presented. Therein, the magnetic hysteresis of the particles are described by a phenomenological, thermodynamically consistent hysteresis model. To connect the microscopic fields to effective macroscop…
Sintered Fe-Cr-Mo-Si-C alloys, produced from two different pre-alloyed powders with compositions of Fe-3.0Cr-0.5Mo and Fe-1.5Cr-0.2Mo, showed a microstructure similar to that of a fully pearlitic ductile cast iron (DCI EN GJS700-2). The two sintered alloys exhibited close values of area fractions of a black particle (…
Glass samples in system (90-x)RWG–10Na 2 O–xNd 2 O 3 . The glass samples were prepared using melt quenching method. The elastic moduli were studied by measurement ultrasonic velocities using pulse echo technique. The structural properties of the glass samples were investigated using infrared absorption spectroscopy. T…
A possibility for hydrogenation of a two-phase magnesium alloy containing intermetallic compound Mg 2 Yb by hydrogen and ammonia is found to yield hydride phases MgH 2 and MgYbH 3.5 in various temperature schedules. The use of ammonia in the range 350–500°C leads to the formation of magnesium and ytterbium nitrides.
In article number 1805306, Zhang-Kai Zhou and co-workers demonstrate a coherent pixel design for metasurface printing-images, in which three optical parameters (i.e. incident wavelength, angle, and polarization) with arbitrary values can be simultaneously used to control image generation and switching. The coherent pi…
A simple, repeatable method for determination of the degree of grain refinement in irradiated Uranium-Molybdenum fuels has been developed. This method involves mechanical potting and polishing of samples along with examination using a scanning electron microscope located outside of a hot cell. The commercially availab…
Abstract Based on an increasing demand of energy and raw materials, resources should be used more efficiently. Therefore, multifunctional materials and lighter constructions, which can endure higher payloads, are needed. Cellular materials like metal foams are bionic, multifunctional materials, which can be optimised…
Abstract In this study, moisture‐permeable waterproof film materials exhibiting temperature‐sensitive hydrophilicity are investigated. The water resistance properties of copolymer films prepared by combining water‐soluble poly(N‐isopropylacrylamide) (poly‐NIPAM) with hydrophilic polyurethane (PU) are examined. Water‐s…
Biodegradable polymeric materials with antimicrobial surfaces could be a suitable alternative for production of medical devices, especially if they are prepared in form of composites containing functional matter. Their greatest advantage is that they do not need to be removed from patient's body and simultaneously the…
The positive (resp., negative) inertia index of a graph G, denoted by p(G) (resp., n(G)), is defined to be the number of positive (resp., negative) eigenvalues of its adjacency matrix. A simple result shows that 1≤d(G)≤2p(G) and 1≤d(G)≤2n(G), where d(G) is the diameter of G. In this paper we determine the sufficient a…
Corrosion inhibition characteristics of aspartic acid on mild steel corrosion in 0.5 M H2SO4 was investigated using weight loss, acidimetry, and electrochemical impedance spectroscopy (EIS). Analysis of the metal surface morphology, uninhibited and inhibited, was carried out through scanned electron microscope. The re…

The reliability of power system has to be assured as it is going to meet a persistent solicit of power consumption. In this scenario, the present power transmission systems should be upgraded to high power transmission capacities without compromising the reliability which is mainly affected by the failure of insulatio…
The Phase Gradient Metasurface (PGMS) is widely used in the flexible control of electromagnetic wave and the improvement of antenna gain. In this paper, a novel type of small-sized metasurface unit cell is designed, and the unit element adopts tri-layer metal and two-layer intermediate medium. Each layer of metal cons…
