Fe 2 O 3 nanoparticle was prepared by a hydrothermal method, and the influence of rare earth elements (Y 3+ , Nd 3+ and La 3+ ) on the electrochemical performance was studied. The crystal structure and microstructure of the synthesized lithium zinc ferrite were characterized by X-ray diffraction (XRD),scanning electro…
The anodic and cathodic polarization dependences for the oxygen electrode based on lanthanum-strontium manganite and the fuel Ni-cermet electrode are studied in the temperature range of 700–900°С in gas media that correspond to working conditions of a reversible fuel cell. The temporal behavior of these electrodes is…
Experimental investigations of solid materials at elevated temperatures rely on the optimized thermal design of the measurement system, as radiation becomes a predominant source of heat loss which can lead to large uncertainty in measured temperature and related physical properties of a test sample. Advancements in su…
The design, fabrication, and performance of an apparatus for the deposition of complex oxides with highly uniform thicknesses at controllable deposition rates over large area, even on the native amorphous SiO2 layer of (001) oriented single crystal Si, are described. The apparatus makes use of the lateral port of a sp…
On the basis of bibliographical, morphological and molecular studies (SSU rDNA), the reinstatement of species rank for Chaetomorpha stricta Schiffner, a poorly known Mediterranean endemic species described in the early 20th century, is proposed. Previously reduced to a posterior heterotypic synonym of C. linum (O.F. M…
ABSTRACT This article presents a method of manufacturing moulding polyimide (PI) from recycling pyromellitic dianhydride‐4,4′oxydianiline PI films. Recycled PI powders were obtained by grinding PI films in high‐energy ball mill. In order to improve the sintering behavior of the recycled PI, a commercial PI powder (tra…
The doping of the Li atom and CO<sub>2</sub> molecule to the X<sub>2</sub>B<sub>8</sub> (X = Be, B and C) backbones have been carried out on the potential energy surface to provide clear vision on the structural and electronic features of the Y@X<sub>2</sub>B<sub>8</sub> (Y = Li, CO<sub>2</sub> and Li&CO<sub>2</sub>,…
Abstract Globally, thousands of tons of food are lost each year due to spoilage and degraded quality. This loss is a current critical issue that must be addressed to ensure adequate food supply for the growing world population; the use of technology and regulatory practices are avenues to a solution. One considered ap…
Gliomas are the most common malignancies of the brain and have a mean survival of 12 months with only 5-10% of the patients surviving for more than 5 years, independent of treatment after diagnosis. Conventional treatment modalities have found the modest success in reducing tumor burden and metastases. Presence of dif…
This article describes the preparation and fundamental properties of a new possible material as a magnetic resonance imaging contrast agent based on the incorporation of preformed iron oxide (Fe 3 O 4 ) nanocrystals into hollow silicon nanotubes (Si NTs). Specifically, superparamagnetic Fe 3 O 4 nanoparticles of two d…
As one of the most basic properties of materials, thermal conductivity is a key parameter to investigate the analysis and design of the particular thermal process, such as the analysis of the thermal/cool energy storage and release process, the thermal/cool energy storage system design, and so on. Also, it is the foun…
Pristine carbon nanotubes (CNTs) exhibit exceptionally high mechanical properties. However, defects like Stone-Wales (SW) and vacancy which appear during manufacturing process affects the performance of CNTs. In this study armchair type single-walled CNTs was considered and 1, 2, 4, 6, 8 and 10 vacancy defects and SW…
Zinc oxide nanostructures with vary pH have been successfully synthesize using a sol-gel method. The nanostructured materials were annealed at low temperature of 300 °C for 3 hour. The effect of pH of the synthesis condition of ZnO on the structural and optical properties of the nanostructures were studied using X-ray…
The interest in magnetic nanoparticles has been growing in recent years, several fields of research are exploring the properties of these materials. Among them, the authors can mention the inclusion of these nanoparticles in materials that perform the cleaning of oil spills, thus producing easy contaminant removal fro…

Effect of FeS doping on large diamond synthesis in FeNi–C system*, Wang, Jian-Kang, Li, Shang-Sheng, Jiang, Quan-Wei, Song, Yan-Ling, Yu, Kun-Peng, Han, Fei, Su, Tai-Chao, Hu, Mei-Hua, Hu, Qiang, Ma, Hong-An, Jia, Xiao-Peng, Xiao, Hong-Yu
Synergistic effect of carbamide and sulfate reducing bacteria (SRB) on corrosion behavior of carbon steel was studied in soils with moisture of 20% and 30%, by soil properties measurement, weight loss, polarization curve, and electrochemical impedance spectroscopy. The results show that carbamide decreased the soil re…
A new scale inhibitor MA/AA/MA-β-CD/SHP was prepared from maleic anhydride, acrylic acid, sodium hypophosphite, and MA-β-CD via the method of free radical polymerization in aqueous solution. The MA-β-CD was obtained through the modification of β-cyclodextrin (β-CD) with maleic anhydride (MA). Results of performance ev…
