A series of γ-Al₂O₃ supported Pt–FeOₓ catalysts (Pt–FeOₓ/Al₂O₃) with different Fe/Pt atom ratios were prepared, and their catalytic properties were investigated in the oxidation of formaldehyde. It was found that the catalytic activities of Pt–FeOₓ/Al₂O₃ catalysts are varied with the change of Fe/Pt ratios. Among them…
Biochar and wood ash are widely studied materials for amending and remediating metal contaminated soils, but often used in isolation. In this study, a pot experiment was set up to compare their relative effectiveness at restoring soil health. A multi-element contaminated soil from a former metal mining site was treate…
This study aimed to model numerically the thermal cycling resulting from the steel ASTM A743-CA6NM remelting process. The problem was solved with the support of the commercial software ANSYS / FLUENT ® 14.5 for the three-dimensional case using the finite volume method. The following simplifying assumptions were adopte…
Large-area monolayer graphene can be synthesized by chemical vapor deposition (CVD) on catalytic copper metal surface. However, the graphene from CVD method usually shows inferior properties as compared to theoretical value of perfect graphene without any structural defects including point defects and grain boundaries…
Stability of polycrystalline binary and multicomponent metallic systems at low homologous temperatures depends on the mobility of the interphase boundaries and segregation kinetics of components at these boundaries. If the interphase boundaries move with sufficiently high velocity, the segregation process starts to de…
p-Xylene is valuable raw material for the chemical and petrochemical industries, e.g., for producing polyesters and plasticizers. Currently, p-xylene is produced by methylation of toluene and toluene disproportionation. The shape-selective alkylation of toluene with methanol is also a promising way of producing p-xyle…
The frequent fog and haze make the main pollutant PM2.5 into public view. In this paper,VOCs as one of the important precursors of PM2.5 was introduced. Furthermore, focusing on the VOCs from petroleum and petrochemical refining companies in our country, sources of the VOCs in petrochemical enterprises were introduced…
Nos ultimos anos, as celulas estaminais mesenquimais (MSCs) surgiram como fortes candidatos terapeuticos para a medicina regenerativa do sistema nervoso central (SNC). Durante a ultima decada, as moleculas com caracter neuroregulador secretadas pelas MSCs isoladas de diferentes tecidos tem demonstrado um imenso potenc…
Phosphonated low-molecular-weight chitosan (P-LMC) was prepared for improving cell adhesion on titanium surfaces. P-LMC was prepared by introducing a phosphonate group from 4-phosphonobutyric acid to low-molecular-weight chitosan. Introduction of the phosphonate group was confirmed by 31P-NMR. Characterization of tita…
The primary goal of this work was to develop and verify a semi-empirical model that is capable of elucidating the mechanisms of interaction between low frequency (20 kHz), low pressure amplitude (55 kPa peak-peak) - corresponding to intensity equal to100 mW/cm2 ((ISPTP), spatial peak, temporal peak) - ultrasound and b…

Nowadays, a large amount of dyewastes, mainly synthetic dyes is continuously released by the textile industry. The component of this dyes, especially acid orange 7 (A07), can block a sunlight penetration and oxygen dissolution in water, leading to seriously environmental and health problems. For removal of dyewastes,…

The Hydrogen Effusion Probe (HEP) is being developed for on-line corrosion monitoring of carbon steel by measuring the rate of hydrogen produced and transported through the metal which corresponds to the corrosion rate as the result of corrosion of the metal. Hydrogen accumulation inside carbon steel and stainless Ste…
Supercapacitors are new king of energy storage devices which have high efficiency and outstanding properties such as high power density and long life cycle. In order to reach high capacitance, choosing the electrode material very important. Carbon material is a great choice due to suitable properties for using as supe…

The catalytic activity and long term stability during combined steam and carbon dioxide reforming of methane (SCR) was investigated on Ni based catalyst. The catalyst was reduced at 800°C for 1 h under a flow of 10 vol% H2 balanced with N2. The reaction temperature was monitored by thermocouple placed in the middle of…
In this study, controlled preparation of polyols with primary hydroxyl and ethylene oxide functionalities are attempted through thiol-ene click coupling reaction between vegetable oil (VO) and different kinds of thiol-containing compounds. Experimental parameters, such as concentrations of chemicals, reactions time, a…
