The paper refers to a composite material developed for manufacturing thermoformed products with applications in furniture making, automotive industry etc., a method and machinery for manufacturing the material in unwoven form. From this material, Research and Development Department of TAPARO SA has designed and built…
In this study, a novel procedure of fabricating a high performance graphene oxide (GO) composite membrane with high water permeability and selectivity was developed.
The aim of the present study is to investigate changes of the mechanical and electrical properties in the Cu-Cr-Zr alloy depending on the thermomechanical treatment history (TMT). The nine cases of the experiments were conducted depending on the combination of the wire drawing and aging. The Cu-Cr-Zr alloy was solutio…
NO˙ suggest that the reaction occurs through the intermediacy of a dinitrosyl complex. In addition, DFT calculations were performed to provide more evidence on the structure of the intermediates and to support the observed reactivity.
The feasibility of using rattan canes (Laccosperma secundiflorum and Eremospatha macrocarpa) as reinforced fillers for high density polyethylene based plastic composite production was investigated. Extruded composites were tested for water sorption, tensile and thermal properties. The results obtained indicated that t…
This paper aims to analyze the quality of insulation in high voltage underground cables XLPE using a prototype which classifies the following usual types of patterns of partial discharge (PD): (1) internal PD, (2) superficial PD, (3) corona discharge in air, and (4) corona discharge in oil, in addition to considering…
and vinyl of 2VP. The origin of the experimentally observed inertness of 1b has also been elucidated. These results could add to the better understanding of the experimentally observed activity discrepancy and shed light on the development of such a catalysis system.
Despite all advances in drug delivery, the limitations of the analytical technologies involved in the characterization of next-generation nanomedicines are still impeding further progress of an emerging market. Discriminating between different formulations and batches, drug release is one of the most important quality…
were prepared by thermally decomposing lanthanide acetylacetonate precursors. Through modifying the molar ratio of the core and shell, nanodumbbell-shaped particles with different sizes and morphologies were precisely synthesized. The formation mechanism and the heterogeneous epitaxial growth process of the nanodumbbe…
In the article the technique of calculation of a three-layer beam with a lightweight filler taking into account the creep of the middle layer is given. The problem reduces to a second-order differential equation, which is solved numerically by the method of finite differences. An example of a calculation is presented…
The well-organized collagen layers on mica surface have drawn extensive attention for its essential applications and studies on the process of self-assembly as a model system. In this work, collagen extracted from fish scales by acid-base method was used to explore the self-assembly characters, and atomic force micros…
A method to analyze the impact of design features of the integral scheme of passenger cars bodies on their stiffness and strength characteristics is proposed. A review of design features of the existing domestic and foreign passenger cars body structures is made. The design features of the integral scheme for the car…
Space charge in 8YSZ is examined theoretically. The Poisson-Boltzmann equation is solved by free energy minimization. The Helmholtz free energy of a crystal containing various defects is minimized subject to two constraints: The total dopant concentration is fixed and the maximum amount of surface charge is limited by…
This article provides a brief overview of the metallic materials used as implants in orthopedics, the alloying system and a complex of the physical-mechanical properties for metallic materials certified for medical use, as well as the advantages and drawbacks of using metallic materials as implants. Approaches to impr…
with low toxicity, excellent cell membrane permeability and high photostability can not only distinguish HeLa cells from mouse embryonic fibroblasts but also target the subcellular organelle lysosome in HeLa cells; therefore it can be anticipated that the as-prepared material would be a potential tool for cancer diagn…

Fluorescent conducting polymers are gaining increasing popularity in actual applications such as electrochromic device, cell detection and fluorescence sensor. This paper describes the synthesis of new both fluorescent and electrochromic polymer. A new bifunctional material 2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)met…
Bismuth oxide exhibits extraordinary ionic conductivity and high surface exchange ability, but the low melting temperature and instability in reducing environment limits its wide application in intermediate temperature solid oxide fuel cells (IT-SOFCs). Herein, we incorporate yttria-stabilized bismuth oxide (YSB) as a…
By using DFT calculations, NMO <sub>2</sub> /TiO <sub>2</sub> hetero-structures show upward band bending, forming an electron depletion layer. The strong internal electric field generated by interfacial electron transfer leads to an efficient separation of photo-generated carriers.
Kenaf natural fibre is used as a sustainable form of material to reinforce polymeric composite. However, natural fibres usually do not perform as well as synthetic fibres. Silica nanoparticle is a material with high surface area and its high interfacial interaction with the matrix results in its improvement. In this r…
