Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced. Here we suggest that the initial process enabling the a

Interestingly, many structural features observed during shear deformation of Al/Cu multilayer have some resemblances to the vortices emerging from Kelvin–Helmholtz (KH) instabilities in fluids (Supplementary Fig. 3), which have been ascribed by some researchers to be the underlying physical mechanism ...
We also note significant positive value of the asymmetry parameter (γ1) for majority of the US ETFs, which indicates stronger reaction of financial markets to bad news in comparison to good news. Finally, the tail coefficients are also significant across all the financial markets. Download: ...
In addition, as compared to the other two methods, CVD has the advantage that the nanotube catalyst structures used to initiate growth can be defined lithographically. Some current methods for creating long SWNTs in a CVD reaction chamber require the use of two or more furnaces. Other methods...
of various chemical and mechanical phenomena such as contact mechanics, lubrication models, chemical reaction that occur between slurry components and films being polished, electrochemical reactions, adsorption behavior and mechanism, temperature effects, and the complex interactions occurring at the wafer ...
According to previous studies [30, 31], the diffusion flux (J) toward the inclusion is proportional to the concentration gradient and can be calculated using Eq. (11). For the given reaction of MnS formation [Eq. (3)], it is assumed that at the interface, the diffusion fluxes of Mn ...
[2]. The main known mechanisms of Cd ion (Cd2+) toxicity in living organisms include its affinity for sulfhydryl groups in proteins and its ability to replace some essential metals in active sites of enzymes, thus causing inhibition of enzyme activities and protein denaturation [2,3]. ...
The early formation of NiSi2 has been observed during the solid state reaction between Ni(W,Pt) films and Si (001) substrates at a temperature of 295 °C. The maximum contents of W and Pt additions are ~28 at.%. In-situ X-ray diffraction (XRD) measurements and rapid thermal proc...
Schematic of hydrogen absorption by metal hydrides. Full size image Formic acid Given that the hydrogen produced from the reaction does not contain carbon monoxide, there is research interest in utilizing formic acid as a hydrogen storage material. The reaction employs ruthenium catalysts that are dis...
