Based on colloidal crystals of various dimensionality, hybrid metal-dielectric plasmonic-photonic heterocrystals have been prepared. It has been shown that the spectra of optical transmission of heterocrystals are mostly controlled by the sum of contributions of composing plasmonic and photonic crystals. At the same t…
By using some types of means such as Optical Microscope (OM), Scanning Electron Microscopy(SEM), the testing of tensile mechanical properties and the testing of friction and wear, the impacts of the Al-5Ti-1B and Al-20Sr modification on the Al-16Si-4Cu-0.5Mg-0.2Mn alloy microstructure, mechanical properties and fricti…
In this study, effect of PBS content on physical properties of polylactic acid (PLA) and polybutylene succinate (PBS) blends was studied. The content of PBS was varied from 0 30 %wt. The blends were mixed using an internal mixer. The samples were prepared using a compression molding. It was shown that tensile strength…
We demonstrate that the Mg-doping in barriers can partially screen the polarization fields of InGaN-based green light-emitting diodes. The photocurrent spectra show that the Mg-doping samples have smaller polarization fields and the blue shift of the peak with increasing current is observed. The reduction of polarizat…
The corrosion properties of copper, nickel, and titanium in both Lewis acidic and basic 1-butyl-3-methyl-imidazolium chloride (BMIC) aluminum chloride (AlCl3) ionic liquids (ILs) are firstly investigated using potentiodynamic polarization, electrochemical impedance spectroscopy, and scanning electron microscopy. Cu sh…
In this paper is presented the improvement against corrosion of the multilayer coatings [TiN/CrN]n with periods of 20, 50, 100 and 200 bilayers deposited by the PVD magnetron sputtering technique on carbon steel AISI 4140. The electrochemical evaluation was performed by electrochemical impedance spectroscopy (EIS) and…
An unusaul mixed-valence uranium(V,VI) oxyhydroxide, Na5[U5O16(OH)2], was synthesized via reduction of UO2(2+) with zinc under hydrothermal conditions at 570 °C and 150 MPa. Its structure consists of extended sheets of edge-sharing U(VI) pentagonal bipyramids and U(V) square bipyramids. The overall anion topology is t…
Abstract 12 vol%WC p /2024Al composite was fabricated from mixed powders by hot‐pressing at various temperatures. Investigation of the interfacial reaction between the WC phase and the Al alloy matrix was performed by X‐ray diffraction (XRD), transmission electron microscope (TEM) and energy dispersive spectroscopy (E…
In-plane properties of paperboard have always been of interest to paper mechanical researchers. The reason for this is that they play a large role for the usability of the paperboard throughout its lifespan. Tensile properties are crucial when the board is fed through printing and converting machines at high speeds in…
The results indicate a reduction of defects in soldering turning tools through optimal dimensions of a solder. In this paper stress in a flat insert is calculated and the results of laboratory tests of cutters iron-carbon soldered are presented. The optimal dimensions of the solder are selected according to calculatio…
This paper seeks to outline a novel three-layer model and a new birth–death element solution technique to evaluate static strength of notched metallic panel repaired with bonded composite patch and to optimize material parameters. The higher order 3D, 8-node isotropic solid element and 8-node anisotropic layered solid…
The aim of this work was to achieve a better understanding of the wettability, i.e. liquids wetting and sorption characteristics (or penetrability), of acetylated Southern yellow pine (SYP) including probable differences in such characteristics between early- or latewood. Matched samples of acetylated and untreated SY…
We propose a quantum-electrodynamics scheme for implementing the discrete-time, coined quantum walk with the walker corresponding to the phase degree of freedom for a quasimagnon field realized in an ensemble of nitrogen-vacancy centers in diamond. The coin is realized as a superconducting flux qubit. Our scheme impro…
Crystalline In-Ga-Zn Oxide (IGZO) including c-axis aligned crystal (CAAC) enables FETs to show high reliability and extremely low off-state current. CAAC-IGZO technology is expected to grow to main technology of next-generation displays and is already contributing to mass-production of liquid crystal displays. In this…
The study of stem cells has evolved rapidly in recent decades. The importance is given to the concept that these cells are potentially able to become any cell type and have the power of self-renewal throughout the life of the organism. Mesenchymal stem cells (MSCs) can be isolated from various organs of the body such…
This study was aimed at investigating the physico-chemical and microbial diversity for rapid composting of sugarcane press mud (PM) leading to organic manure. Five bacterial strains (Cellulomonas sp., Klebsiella sp., Proteus sp., Enterobacter sp., Salmonella sp.) were tested under in vivo conditions for bioconversion…

The Equilibrium Theory of Inhomogeneous Polymers provides an introduction to the field-theoretic methods and computer simulation techniques that are used in the design of structured polymeric fluids. By such methods, the principles that dictate equilibrium self-assembly in systems ranging from block and graft copolyme…
LiCoO2 thin films used as cathode layers in thin-film solid-state batteries have been deposited from LiCoO2 powder target using radio frequency (rf) magnetron sputtering in a cost effective approach in terms of material consumption and processing time.
