In this study, the effect of natural anhydrite (CaSO4) powder additions on the microstructure and hardness of a Cu-8Sn bronze composite, prepared by a powder metallurgy process, were examined. Natural anhydrite powder, ranging in content from 2 to 8 percent by weight was added to a premixed powd...

The hydrogen embrittlement behavior of multilayer steel consisting of 7 alternating layers of martensitic (MART) steel and twinning-induced plasticity (TWIP) steel was investigated through variation in the ratio of the hard layer to the soft layer, and the size of the grains according to the aut...

Implementing melting function on pavement without reconstruction lead to cleaner pavement engineering. This study proposed the reusing of steel slag to design ultra-thin friction courses for pavement maintenance with ice and snow melting functions. Reusing the steel slag in the proposed ultra-th...

High manganese steel has been widely used in the national defense, automobile and petrochemical industry fields due to its excellent wear resistance and low temperature toughness. Alumina-magnesia refractory plays a significant role in high manganese steel smelting. In this paper, the interactio...

Steel-concrete-steel (SCS) sandwich structures have important advantages over conventional concrete structures, however, bond-slip between the steel plate and concrete may lead to a loss of composite action, resulting in a reduction of stiffness and fatigue life of SCS sandwich structures. Due t...

Galvanized steel is welded to stainless steel for various structural applications. In this regard, the effect of zinc on the mechanical properties of galvanized low carbon steel and 316L stainless steel weld was studied. Welding was done using two shielding gas combinations; Ar + 2%O2 and Ar + 2...

Germany’s largest known magmatic Ni-Cu-(PGE) sulfide enrichment is associated with the gabbroic Angstberg intrusion that is one of several small-scaled, Ni-Cu sulfide-bearing intrusions in the northern Bohemian Massif (Central European Variscan Belt). The intrusions are part of a Middle Devonia...

Beneficiation of zinc from low-grade oxidized zinc ores has become the focus of recent studies. Sulfidation is an important process to recover zinc from oxidized zinc ores in flotation. Although some studies have reported on the sulfidation-flotation of smithsonite, the effect of sulfide ions on...

The addition of chemical agents to control the production of hydrogen sulfide (H2S) is currently the principal technology used to control odor emissions from sewers. In this study, laboratory reactors were used to investigate the change in dimethyl trisulfide (DMTS) concentrations when dosing wi...

Hydrogen sulfide having the detrimental effect on humans and ecosystems can be metabolized by sulfur-oxidizing bacteria (SOB) as an energy source, however, SOB cannot tolerate high sulfide levels. A hybrid two-phase process was therefore proposed in this work to enhance the high-level sulfide ox...

We conduct a theoretical, first-principles study of thallium sulfide with the space group FM-3M. We determine the electronic structure, phonon dispersion relations, Eliashberg spectral function, electron-phonon coupling constant (λ) and any superconductivity. The results indicate that this stru...

A new method was proposed for hydrogen sulfide removal from natural gas through the utilization of supersonic flow in a Laval nozzle. For this purpose, a mathematical model was established for the supersonic non-equilibrium condensation flow of the binary methane-hydrogen sulfide mixture. The co...

In the temperature range of 388–506 K in saturated vapor over 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMImTfO) ionic liquid along with the monomer neutral ionic pairs (NIP) C+A–, where C+ is EMIm+ (cation) and A– is TfO– (anion), the dimers (C+A–)2 were registered with a frac...

The conversion of furfuryl alcohol (FA) and selectivity towards dimers (C9-C10) and trimers (C14-C15) were investigated over molybdenum oxide (MoO3) catalyst. It was observed that FA conversion increased as an increase of reaction time. However, longer reaction time tended to limit the selectivi...

Temperature-dependent reactions of molybdates with histidine in weak acidic solution resulted in the isolations of coordinated and uncoordinated products Na[MoΛO3(S-His)]·H2O (1) (HHis = histidine, C6H9N3O2) and K4(S-H2His)2(Mo7O24)·16H2O (2) respectively. The former 1 can be reduced by hydra...

Niobium and cerium dopants of mesoporous cellular foams, MCF, have been recently considered as promoters enhancing the basicity of amino-organosilanes anchored to the supports. Thus, the knowledge of acid-basic properties of niobium and cerium containing MCFs is important. Therefore, in this wor...

Bismuth compounds have been widely used for the treatment of ulcers and Helicobacter pylori infection, and enzyme inhibition was thought to be crucial for bismuth anti-microbial activity. We have investigated the interaction of colloidal bismuth subcitrate (CBS) with alcohol dehydrogenase and ou...

The NikR protein is an essential DNA regulator of Helicobacter pylori, a human pathogen, which infects almost half of the world's population. Herein, we comprehensively characterized the interaction of a bismuth drug with Helicobacter pylori NikR. We show that Bi(III) can occupy the high-af...

Two different clay nanocomposites, as sepiolite-Ag and kaolinite-Ag, are studied as carriers for silver nanoparticles (AgNPs) oral administration as antimicrobial agent in additives for animal feed. A three-step digestibility assay, corresponding to stomach, small and large intestine simulations...

Although silver nanoparticles are the most widespread product of nanotechnology, the mechanisms underlying AgNP microbial toxicity remain the subject of intense debate. In this study, Bacillus subtilis has been used as model organism to elucidate the molecular interactions between this class of ...
