The equiatomic CoCrFeMnNi alloy and the quaternary alloys with no addition of one element were fabricated, roles alloying elements in corrosion resistance clarified. In 1 M H2SO4, passivity was mainly due to Cr. Co Fe additions also contributed decrease current density. While Ni found suppress active dissolution, Mn increased dissolution rate. without indicated superior pitting 0.1 NaCl. To imp...

We report the detection of H emission in the T dwarf (methane brown dwarf) 2MASSW J1237392+652615 over three days using the Keck Low Resolution Imaging Spectrograph. The measured line ux, log(L H /L bol) = ?4.3, is roughly consistent with early M dwarf activity levels and inconsistent with decreasing activity trends in late M and L dwarfs. Similar emission is not seen in two other T dwarfs. We ...

We report the detection of Hα emission in the T dwarf (methane brown dwarf) 2MASSW J1237392+652615 over three days using the Keck Low Resolution Imaging Spectrograph. The measured line flux, log(LHα/Lbol) = −4.3, is roughly consistent with early M dwarf activity levels and inconsistent with decreasing activity trends in late M and L dwarfs. Similar emission is not seen in two other T dwarfs. We...

High altitude pulmonary edema (HAPE) is a paradigm of pulmonary edema. Mutations in regulator of telomere elongation helicase1 (RTEL1) represent an important contributor to risk for pulmonary fibrosis. However, little information is found about the association between RTEL1 and HAPE risk. The present study was undertaken to tentatively explore the potential relation between single-nucleotide po...

Using natural plant extracts on metallic substances is the most frequently studied green corrosion inhibition approach in science. In this work, Coriaria nepalensis Stem Alkaloid (CNSA) has been successfully extracted and characterized by qualitative chemical (Mayer’s Dragendroff’s) test spectroscopic (UV FTIR) measurement. CNSA employed as a inhibitor for Mild Steel (MS) subjected to 1 M H2SO4...

Anomalous excess heat in Pd|D2O+H2SO4 electrolytic cells was confirmed using an accurate method of heat measurement, Seebeck Envelope Calorimetry. A cell was placed in the calorimeter, which measures the output heat flux directly and avoids many of the problems other methods have. The maximum excess power thus far was 1.3 W (or 11 W cm3) with input power of 13 W at a current density of 0.4 A c...

The influence of 3-methyl-2,6-diphenyl piperidin-4-one (MDPO) and 2phenyl decahydroquinoline-4-one (PDQO) synthesised in the laboratory on hydrogen permeation and corrosion inhibition of mild steel in 1N H2SO4 has been studied using weight loss and various electrochemical AC and DC corrosion-monitoring techniques. Both the compounds inhibit the corrosion of mild steel in H2SO4. Potentiodynamic ...

The corrosion inhibition behavior of cefuroxime was investigated on mild steel in 2 M H2SO4 solution using electron impedance spectroscopy measurement and Quantum chemical studies. inhibitive effects the studied compound increase with increasing concentration study revealed that is a mixed-type inhibitor studies corroborate experimental results.
