Magnetocrystalline anisotropy (MCA) of the Fe-based transition-metal thin films was investigated by means of first principles full-potential linearized augmented plane wave method. A giant perpendicular MCA (PMCA), up to 3 meV, was confirmed in a 7-layer Fe-Ni film/MgO(001), where an Fe2/Ni/Fe/Ni/Fe2 atomic-layer alig…
Doxorubicin (DOX) is an effective antitumor drug employed for treatment of a wide range of cancers types such as neuroblastoma, osteosarcoma, breast and esophageal carcinomas. On the other hand, the cumulative dose is restricted (300-550 mg/m(2)) and its amount administered to a patient has to be closely controlled du…
CaCu 3 Ti 4 O 12 (CCTO)–poly(vinylidene fluoride (PVDF)) composites were prepared by melt blending and hot molding techniques. The addition of CCTO remarkably enhanced the dielectric properties and the thermal conductivity of PVDF composites, while the melting point of the PVDF composites (~170°C) was almost independe…
Cationic starch microspheres (CSMs) were prepared from lab-made neutral starch-based microspheres using a cationic adsorbent, namely 3-chloro-2-hydroxypropyltrimethyl ammonium chloride, as the cationic etherifying agent. Detection by scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), and las…
Results of researches of carbon materials gasification by СО2 , Н2О and their mixture are presented Speed advantages of steam gasification are set in comparison with carbon-dioxide one. Such result is not concordant with thermodynamics possibilities of process at temperatures higher ~1073 К and can be explained by con…

Telah dilakukan analisis simulasi larutan U-nitrat sebagai target iradiasi neutron untuk produksi radioisotop Mo-99. Uranium dalam senyawa nitrat diperkaya dengan 20% berat U-235. Analisis simulasi dilakukan berdasarkan pa…
The adsorption of Zn-tetraphenylporphyrin (ZnTPP) on nanoporous hierarchically organized anatase TiO 2 structures and the properties of the corresponding hybrid interface were studied by synchrotron radiation experiments. The molecular structure, electronic properties, and bonding with nanostructured TiO 2 surfaces we…
One of the most common applications of ferrocement is the manufacturing of thin stiffened plates which are prone to buckling. This study focuses on the investigation of the behavior of a ferrocement plate, stiffened in both directions by means of an appropriate grid of ribs. In the present paper detailed three-dimensi…
Nanostructures of two new copper(II) complexes, (CuL1), 0.5EtOH. 1.5H2O (1), [H2L1=5-(4-Carboxy phenyl azo) anthranilic acid], (Cu(L2)2) (2), [HL2=1-(4-Carboxy phenyl azo) 2-naphtol] have been synthesized by the reaction of H2L1 and HL2 with Cu(OAc)2 · H2O through sonochemical process. Calcination of the nano-sized co…
In this work, a comprehensive approach to model the structural behaviour of Reinforced Concrete (RC) beams subjected to reinforcement corrosion is proposed. The coupled environmental - mechanical damage model developed by some of the authors is enhanced for considering the main effects of corrosion on concrete, on com…
This paper is focused on the influence of Ni addition on the microstructure and fracture toughness of structural steels after tempering. Nickel is known to increase the resistance to cleavage fracture of steel and decrease a ductile–brittle transition temperature. The medium carbon, low alloy martensitic steels attain…
We investigated the relaxation behavior of InGaN/GaN blue multiple quantum wells (MQWs) grown on Si (111) and sapphire (0001) substrates to determine how the threading dislocation density (TDD) in the underlying GaN layer, the thickness of the MQWs, and the growth substrate (Si or sapphire) affect the relaxation behav…
Two new energetic derivatives of 1-amino-3-nitroguanidine were synthesized. The furoxan moiety and 2,4,6-trinitrophenyl moiety were introduced to the nitroguanidine frame. The resulting compounds 3-methyl-4-((2-(N′-nitrocarbamimidoyl)hydrazono)methyl)-1,2,5-oxadiazole-2-oxide (1, C5H7N7O4) and N′-nitro-2-(2,4,6-trinit…
The lifetimes and spin–lattice relaxation time of photo-excited triplet electron of pentacene doped in p-terphenyl at room temperature have been investigated. Values of spin–lattice relaxation time previously reported in ESR studies are inconsistent with each other. In this paper, we determined these time constants ba…
In order to enhance the energy-absorbing behaviour of both new and existing metallic structures, metal cylinders are reinforced by inserting an internal composite cylinder. Initially, the energy-absorbing characteristics of the individual composite and metal rings with a large variety of the diameter-to-thickness rati…
The application of Machine Learning to cheminformatics is a large and active field of research, but there exist few papers which discuss whether ensembles of different Machine Learning methods can improve upon the performance of their component methodologies. Here we investigated a variety of methods, including kernel…
This paper presents a detailed analysis of the degradation kinetics and of the reliability of state‐of‐the‐art InGaN‐based green laser diodes (LDs), submitted to CW stress tests at different operating conditions. Results described in the following indicate that: (i) constant current stress induces an increase in thres…
Migration testing of bisphenol A (BPA) from low-density polyethylene (LDPE) into food simulants was performed as a function of three factors: temperature, initial BPA concentration, and food simulant type. An HPLC–UV method was applied to measure the amount of BPA that migrated into the solvents. The migration process…
Highly ordered mesoporous tungsten trioxide ( WO 3) with high surface area (75 m2/g) and well-defined mesopores were successfully prepared through a hard templating method using a mesoporous silica KIT-6 as a template and ( NH 4)6 H 2 W 12 O 40 ⋅ x H 2 O as a tungsten precursor. Oxidative desulfurization of a model oi…
Real-time imaging of (13)C metabolism in vivo has been enabled by recent advances in hyperpolarization. As a result of the inherently low natural abundance of endogenous (13)C nuclei, hyperpolarized (13)C images lack structural information that could be used to aid in motion detection and anatomical registration. Moti…
