Cadmium Oxide (CdO) nanoparticles were prepared by precipitation method using Cadmium acetate and ammonia solution. Presence of chemical species, were verified by Fourier Transform Infra Red (FTIR) Spectrum. From X-Ray Diffraction (XRD) spectrum the particle size, d-spacing value and structure of the nanoparticle were…
The neutron diffraction isotopic substitution technique is employed to investigate the environment of Fe2+/Fe3+ cations in a soda–lime–silica glass. Data were recorded for three samples; the base glass, the base glass incorporating natural Fe2O3 and a similar glass containing isotopically-enriched 57Fe2O3, and were Fo…
Polyaniline (PANI) as active material of batteries possesses excellent electrochemical reversibility. It is a promising candidate for a rechargeable battery with a high performance. However, the electrochemical degradation of polyaniline becomes a bottleneck of PANI battery. The sulfanilic acid and anthranilic acid as…
A novel generation of PEDOT:PSS/PPY and PEDOT:PSS/PANI bilayered nanofilms were successfully prepared by electrochemical polymerization in a mixed alcohol solution of isopropyl alcohol (IPA), boron trifluoride ethyl ether (BFEE), and polyethylene glycol (PEG), based on a PEDOT:PSS nanofilm electrode. The structure, el…
The three chalcones namely (E)-3-(4-hydroxyphenyl)-N-phenylacrylamide (INH-1), (E)-3- (4dimethylamino)phenyl)-N-phenylacrylamide (INH-2) and (E) -3-(4-hydroxy-3-methoxyphenyl)-N- phenylacrylamide (INH-3) were synthesized and their corrosion inhibition properties on mild steel in 1M HCl was investigated using weight lo…
We present an experimental study of the magneto-optical activity of multiple excited excitonic states of manganese-doped CdSe quantum dots chemically prepared by the diffusion doping method. Giant excitonic Zeeman splittings of each of these excited states can be extracted for a series of quantum dot sizes and are fou…
Abstract The thallium triborate HP-TlB 3 O 5 (HP=high-pressure) was synthesized in a Walker-type multianvil apparatus under high-pressure=high-temperature conditions of 6 GPa and 1400°C. A mixture of thallium carbonate Tl 2 CO 3 and boric acid H 3 BO 3 initially heated at 850°C under ambient-pressure conditions was us…
Nanostructured gold and silver thin films were grown by pulsed laser deposition.Performing the process in an ambient gas (Ar) leads to the nucleation and growth ofnanoparticles in the ablation plasma and their self-organization on the substrate. Thedependence of surface nanostructuring of the films on the deposition p…
The dielectric, magnetic, and magnetodielectric properties of Ca2FeAO5+δ (A = Al, Ga) ceramics were investigated together with their crystal structures. Rietveld refinement of the X-ray diffraction data indicated that the space group of the Ca2FeAlO5+δ ceramic was Ibm2, whereas that of the Ca2FeGaO5+δ ceramic was Pcmn…
Abstract Polyethylene terephthalate (PET) foils have been exposed to oxygen plasma and its afterglow in order to reveal compositional and structural modifications of the surface layer. Oxygen plasma was created by electrode-less RF discharge in a glass chamber so the O-atom density was close to 1022 m -3 although the…
Nucleation and growth of zirconium-oxo-alkoxy (ZOA) nanoparticles were studied in a sol-gel process in n-propanol solution at a hydrolysis ratio H between 1.0 and 2.7 and zirconium-n-propoxyde precursor concentrations between 0.10 and 0.15 mol l(-1). The chemical transformations were conducted in quasi-perfect micromi…
The purpose of this study was to evaluate the effects of Nano-silver (NS), calcium chloride (CaCl2) and their combinations on Gerbera jamesonii ‘Carambole’ cut flowers. The experiment was conducted as a completely randomized design (CRD) with 10 treatments and four replications, with three flowers in each replication.…
The development of nontoxic effective corrosion inhibitors for metallic substrates is an issue of great importance for protection of metal alloys and components. Surface properties of new stabilized magnetic nanoparticle (MNP) colloids coated with Myrrh gum were investigated. The natural product Myrrh gum was used as…
The increased public attention on the waste pollution and the awareness of the hard environmental problems is the reason for the need of new materials which are susceptible to degradation in nature for a short period of time. The biopolymer films and coatings based on renewable natural sources are suitable for obtaini…
Single reactor deposited crystalline Si/WO <sub>3</sub> core–shell nanowires showed superior optical absorption and enhanced photocurrent conversion.
The chemistry of zinc hydrides, including the main approaches to the synthesis, structure and physicochemical properties of compounds containing zinc-hydrogen bond, is systematized the review.
Transmission and distribution power network commonly use porcelain insulator for the isolation i.e. insulation between line conductors and supporting structure. Most of the insulators are mounting in open-air applications. So, gradually contamination is deposited in the surface of the insulator and reduced the voltage…
Effect of pre-induced twinning on the microstructure evolution and mechanical properties of extruded Mg-9.26Gd-2.08Y-0.36Zr (GW92K) alloy have been investigated during multi-direction forging with large strains at decreasing temperature from 400 °C to 300 °C. The results showed that, whether there pre-induced twinning…
We have determined experimentally the magnitude of the difference in the splay and bend flexoelectric coefficients, |e1 − e3|, of an oxadiazole bent-core liquid crystal by measuring the critical voltage for the formation of flexodomains together with their wave number. The coefficient |e1 − e3| is found to be a factor…
In addition to the earlier known vertic alluvial soils (slitozems) of the Volga-Akhtuba floodplain, 44 new areas of Vertisols and vertic soils (according to the WRB), or dark slitozems (according to the new Russian soil classification system), have been found in the Middle and Lower Volga regions from the forest-stepp…
