Antibacterial activity of materials synthesized from clay minerals
The antibacterial activity of silver and cationic surfactant modified smectites from North Patagonian, Argentina, were tested in growth inhibition of Escherichia coli bacteria by the test of susceptibility on solid medium. The exchange reactions were carried out using Ag and hexadecyltrimethylammonium (HDTMA) cations in larger amounts than those conventionally required to form monolayer on the ...
متن کاملWettability of Carbonaceous Materials with Molten Iron at 1550°C
In the direct iron smelting process, interfacial reactions of carbonaceous materials with molten iron are among some of the key factors that dictate the rate of carbon transfer into molten iron and establish a carbon concentrated melt to reduce iron oxide in the slag phase. Detailed wettability investigations on a range of carbonaceous materials, e.g. synthetic graphite, natural graphite, coke,...
متن کاملDissolution and formation of nuclear materials in molten media*
As innovative means to recover actinides from irradiated fuels, pyrochemical processes are proposed. In the Japan Atomic Energy Research Institute (JAERI), the feasibility of applying molten-salts processes to nitride fuels containing transuranium elements for transmutation is investigated. In the course of study, experiments and analyses have been made on the high-temperature chemistry of M–N–...
متن کاملThe Effect of Nano-Additives on the Hydration Resistance of Materials Synthesized From the MgO-CaO System (RESEARCH NOTE)
In this study, the effect of variety of Nano- additives doping on the hydration resistance of the MgO-CaO system was investigated. Samples were prepared from calcined dolomite and magnesite. Nano-additives that contained cations with various valences (trivalent and tetravalent) used as a dopant. The bulk density, apparent porosity and hydration resitance were studied and evaluated. Also, phase...
متن کاملInfluence of humidity on the friction of diamond and diamond-like carbon materials
The friction of diamond and diamond-like carbon (DLC) materials was evaluated in reciprocating sliding wear testing under controlled relative humidity. The testing conditions were a displacement stroke of 100 mm, an oscillatory frequency of 8Hz and a normal load of 2N. The coefficient of friction of diamond and hydrogen-free DLC (a-C) coatings against a corundum sphere in the steady regime decr...
