Triglycine Sulphate (TGS) is finds applications in many areas of ferroelectrical studies. Pure TGS crystals have some disadvantages both in properties and growth process. To overcome these problems, effect of doping has been adopted as one of the standard methods. In this regard the doping study of Ba2+ ions on TGS ha…
Schottky junction ultraviolet (UV) photodetector was fabricated by spin coating a hole conducting polymer, poly 3,4-ethylenedioxythiophene: polystyrene sulfonate (PEDOT:PSS) on hydrothermally grown zinc oxide (ZnO) nanorod arrays. The UV detector performance was significantly improved two step process. Firstly, ZnO na…
For the first time cationic surfactant assisted ultrasound synthesis route has been used for the preparation of pure and Nd3+ (0.5-9 mol %) doped Zn2SiO4 nanophosphors. The shape, size and morphology of the products were tuned by controlling the various experimental parameters. The final product was well characterized…
Polycrystalline Ti2AlC alloys were prepared by spark plasma sintering of high purity elemental materials, and subsequently annealed at 1500℃ for 24 h. Nanoindentation behavior was studied on the grains with their surface normal directions parallel to 〈3362〉, 〈4481〉, 〈0001〉 and 〈1120〉. During loading of nanoindentation…
The aim of this study is to elucidate the biochemical properties of manno-oligosaccharides (MOS) hydrolyzed by extracellular enzyme of Bacillus N3. We strived to characterize the biochemical properties of MOS since N3 can effectively hydrolyzed natural polymannans such as galactomannan (GM) and konj...
Context: Thuja occidentalis is prescribed in Homoeopathy in treating rheumatoid arthritis. We speculated the anti-arthritic mechanism of Homoeopathic dilutions of Thuja occidentalis against the complete Freund's adjuvant (CFA)-induced arthritis in rats. Materials and Methods: Arthritis was induced (n = 28) by subplant…
This work aims to investigate the effect of TiO 2 nanoparticles addition on the fluorescence emission of solutions of Rhodamine 6G excited in micro-volumetric droplets. In this paper are presented the similarities and the differences of the emission spectra by modifying parameters such as TiO 2 concentration, solution…
Oxidative kinetics resolution of racemic aromatic sulfoxide was studied by using chiral porphyrin-inspired N-4 ligands and manganese in situ complex as catalyst, environment-friendly H2O2 as oxidant and adamantanecarboxvlic acid as additive. The arylalkyl and arylbenzyl sulfoxide substrates were extended by this catal…
The article is devoted to issues of amines production from nitro compounds. The processes of catalytic reduction of aromatic nitrocompounds by hydrogen to amines have practically superseded all other methods for the production of aromatic amines in large-tonnage plants. Aromatic mono-, di- and polyamines, due to their…
Pine-fruit shell (PFS) is a lignocellulosic residue derived from the fruit of Araucaria angustifolia, a coniferous tree native of South America, part of a whole vegetation of the Atlantic Forest, found in the South and Southwest of Brazil. In this work PFS will be characterized and used in the production of PFS-based…
The generation of waste and its treatment is a challenging problem nowadays. Rubber that is generally considered for recycling comes from the tyres of vehicles. After their use, the waste tyres can lead to hazardous effects to both public health and the environment due to inappropriate disposal or storage. The used ru…

A method is proposed for estimating the hydrogenation (hydrogen penetration) of a steel structure during its operation in a water-containing environment at an elevated temperature and excess pressure. Suppose that the structure is a rotating steel shell with variable geometric and physical-mechanical parameters along…
In the becoming years, energy demand is expected to grow faster than current needs. Thermoelectric technology works through conversion process from heat energy into electricity directly and vice versa. Thermoelectric device that use for energy conversion from heat into electrical is known as thermoelectric generator (…
Titanium alloys have found wide application in the aircraft industry. They are in use as materials for products for which the period of safe operation is very significant. The internal structure and service life of components heavily depends on their manufacture and operation processes. Besides, it is important to tak…
Thermoset-based polymer matrix composites are widely used for production of intumescent fire protective coatings; many operational properties of such coatings can be further enhanced by means of nanoscale layers between matrix and disperse phases. The dependence between temperature of processing and temperature of gla…
The present work aims a study of the room-temperature evolution of soft mode components (E(1TO) and A(TO)) via Raman spectroscopy in superlattices with BaTiO3/(Ba, Sr)TiO3 composition. The quantitative information on the soft modes has been obtained through the computer modeling of Raman spectra using the relaxator an…
The use of natural fibers to replace synthetic fibers as reinforcement in polymer composites has received growing attention in the 21st Century. This is occasioned by global campaigns for utilization of eco-friendly materials as substitute to the conventional non-biodegradable materials which adversely affect the envi…
The article considers the approach to solving such problems of technical diagnostics and industrial safety expertise, such as carrying out a “stress test”, namely loading to the yield point with subsequent leak testing, and estimating the residual life of the technical device. The approach is based on research of loca…
Plastic composites were made from corncobs and high density polyethylene (HDPE) by extrusion and evaluated. The composites were manufactured using two different screened corncob particle size fractions (<2 mm and <0.5 mm) and tested for flexural properties, water sorption, melt flow and thermal properties. The melt vi…
