Fe-based nanocrystalline ribbons were successfully prepared. The giant magneto-impedance (GMI) effect that was found in these studies could be effectively increased by temperature annealing together with stress annealing. After applying a certain stress, the same GMI effect can be obtained with a much lower annealing…
Effect of Zn addition on the microstructure and mechanical properties of Mg-Zn alloys with Zn contents from 6 to 10 weight percent was investigated in this study. Through calculation of phase equilibria of Mg-Zn alloys, carried out by using FactSage® and FTLite database, solution treatment temperature was decided as t…
Seven new prenylated indole alkaloids, taichunamides A-G, were isolated from the fungus Aspergillus taichungensis (IBT 19404). Taichunamides A and B contained an azetidine and 4-pyridone units, respectively, and are likely biosynthesized from notoamide S via (+)-6-epi-stephacidin A. Taichunamides C and D contain endop…
Abstract The authors look toward the future of specifying coating projects starting with the traditional prescriptive, means-and-methods, coating formula-based specifications. The popular qualified product list (QPL) approach is presented along with its drawbacks. The design/build (DB) ideal and limitations of specify…
Abstract A previous paper presented by the authors at SSPC 2015 demonstrated the futility and folly of attempting to use accelerated corrosion testing as a tool for predicting real world corrosion performance. The effect of corrosion was shown to be governed by the type of ions and the concentration of oxygen in the c…
Raman spectroscopy is one of the vibrational spectroscopic methods and has been considered a useful analytical technique to assess food quality Inelastic light scattering of the incident light from a sample creates the Raman signals, which is related to characteristic molecular vibrations of analyte molecules. This gi…
The paper analyses the ratio between the number of Compton-scattered quanta excited in elements of radiation protection coatings by isotope Am-241 and the number of fluorescence quanta excited in in the same elements, taking into account the fluorescence yield coefficient and the distance between the energy of primary…
Nowadays in our modern world there is a vital question of quality control of details made from nonmetallic materials due to their wide spreading. Nondestructive penetrant testing is effective, and in some cases it is the only possible method of accidents prevention at high- risk sites. A brief review of check sample n…
RATIONALE: Electrospray ionization mass spectrometry (ESI-MS) has been employed to study species distribution in controlled acid-catalyzed hydrolysis and condensation of (3-chloropropyl)trimethoxysilane (CPTMS), which is frequently used in the synthesis of hybrid silica-based materials. METHODS: The conditions of anal…
Abstract The conventional NaN3/oxidants gas generator pyrotechnic mixtures suffer from leaving undesirable solid residues. The presented investigation aimed to overcome this problem through mixing of NH4N3 particles with some metallic components, and to introduce some new gas generator pyrotechnic mixtures. In this wo…
Perkembangan teknologi bahan konstruksi saat ini menunjukkan kecenderungan penggunaanmaterial yang semakin efisien sesuai dengan kebutuhan. Salah satunya adalah penggunaanmaterial baja ringan sebagai elemen struktur dalam konstruksi bangunan. Dalam perakitanelemen struktur menjadi satu kesatuan, sistem sambungan pada…
Experimental platform that allows precise spatial positioning of biomolecules with an exquisite control at nanometer length scales is a valuable tool to study the molecular mechanisms of membrane bound signaling. Using micromachined thin film gold (Au) in layered architecture, it is possible to add both optical and bi…
AuCl(PPh 3 ) was mixed with various kinds of inorganic supports with a mortar. Thermal treatment of the mixture resulted in the formation of gold nanoparticles, particularly when NaY zeolite and CeO 2 were employed as the supports for gold. Catalytic performance in the aerobic oxidation of benzyl alcohol was in good c…
This paper proposed a new architecture design for nanowire-based quantum-dot-sensitized solar cells to improve the photovoltaic performance. Microstructured rough substrate was used to increase the surface area of the photoanode without influence on charge carrier transport in the system. Compared to conventional devi…
1,4,8,11-Tetraazabicyclo[6.6.2]hexadecane-4,11-diacetic acid (CB-TE2A) is of much interest in nuclear medicine for its ability to form copper complexes that are kinetically inert, which is beneficial in vivo to minimize the loss of radioactive copper. The structural chemistry of the hydrated HCl salt of CB-TE2A, namel…
Gas tungsten arc (GTA) welding of Ti alloy Ti6Al4V is carried out in vertical-up direction. Weld parameters for the Ti6Al4V alloy were developed using Ti6Al4V (ELI) alloy filler wire and following two pass welding process. X-ray radiography was carried out to ensure the soundness of the weld. Tensile strength of the w…
The article is devoted to designing the high - frequency betatron. In high - frequency betatron most important problem is overheating of the elements of the body radiator unit. In an article some directions of solving this problem are shown.
Supramolecular networks are an important subset in the field of coordination polymer (CP) frameworks and are widely encountered in crystal engineering research. The search for novel topologies continues to be a significant goal in CP chemistry. The dimeric compound bis(μ-5-carboxybenzene-1,3-dicarboxylato-κ(2)O(1):O(3…
Coordination polymers constructed from metal ions and organic ligands have attracted considerable attention owing to their diverse structural topologies and potential applications. Ligands containing carboxylate groups are among the most extensively studied because of their versatile coordination modes. Reactions of b…
A non-resonant magnetoelectric (ME) energy converter is presented for scavenging power-frequency magnetic field energy from two-wire power cords. The device is composed of a Terfenol-D/Pb(Mg1/3Nb2/3)O3-PbTiO3(PMNT)/Terfenol-D ME transducer, a NdFeB manget, and E-shaped magnetic yokes. The ME transducer, the magnet, an…
