copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

The outstading mechanical properties of bimodal ultrafine eutectic composites (BUECs) containing length scale hierarchy in eutectic structure were demonstrated by using AFM observation of surface topography with quantitative height measurements and were interpreted in light of the details of the deformation mechanisms by three different interface modes. It is possible to develop a novel strain ...

Abstract Examinations of two-component mixtures, namely: triphenylamine + centralite I (TPA CI) and akardite II AkaII) were carried out using differential scanning calorimetry (DSC), which served to determine phase diagrams. Experimental data described with NRTL model eutectic points for both systems determined. For TPA CI system, they equal x Eu,TPA = 0.2899, T Eu 62.9 °C, whereas AkaII system...

The electrodeposition of copper onto Au(111) from Deep Eutectic Solvents (DESs) type III has been studied by cyclic voltammetry. Investigations were carried out with mixtures choline chloride (ChCl) and ethylene glycol (EG) or trifluoroacetamide (TFA). eutectic compositions temperatures determined differential scanning calorimetry (DSC). For the ChCl/EG DES, a ratio 16 : 84 (ChCl:EG) was found ...

Essential oils (EOs) offer interesting biological properties that can be altered by their high volatility and low solubility. This study examined, for the first time, effect of combination different choline chloride (ChCl) based-deep eutectic solvents (DESs), water cyclodextrins (CDs) on retention solubilization Eucalyptus citriodora EO its major component, citronellal. The density, viscosity p...

Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of so...

[1] Using first-principles molecular dynamics (MD) simulations, we study the solubility of argon in molten iron at high pressures and temperatures. In particular we explore whether the low pressure immiscibility of liquid Fe and Ar persists to high pressure (130 GPa) and temperature (4500K), or whether they mix. Starting from a variety of Fe/ Ar mixtures we find that they always separate rapidl...
