Development of in-born porous nature of zirconium hydroxide nanopowders through a facile hydrogen (H2) gas-bubbles assisted borohydride synthesis route using sodium borohydride (NaBH4) and novel information on the temperature-mediated phase transformation, pore geometry as well as pore hysteresis transformation of in-born porous zirconium hydroxide nanopowders with the help of X-ray diffraction...

This paper reports the results in the effort to destabilize lithium borohydride for reversible hydrogen storage. A number of metals, metal hydrides, metal chlorides and complex hydrides were selected and evaluated as the destabilization agents for reducing dehydriding temperature and generating dehydriding-rehydriding reversibility. It is found that some additives are effective. The Raman spect...

The specificity of a GC/MS assay of morphine and codeine was examined with particular regard to the potential interference due to hydromorphone and hydrocodone, compounds that cross-react extensively in opiate screening tests. A GC/MS method with solid-phase extraction and acetylation or trimethylsilylation was used. The equilibrium between keto and enol forms of the potential interferents was ...

Since the pioneer studies of Keilin and Hartree (l), considerable evidence has accumulated indicating that cytochrome c oxidase contains two heme moieties that react differently; hence the designation cytochrome U-Q. Reasons for this designat.ion include kinetic studies that show (a) differences in the rate of reduction and oxidation of cytochrome c oxidase measured at the a versus y absorption...

Direct Borohydride Fuel Cells (DBFCs) are considered as promising power sources for portable and mobile applications. Their advantages high theoretical energy density, cell voltage. Metallic Ni has recently emerged a electrode material DBFCs. In this work we combine electrochemical, operando Fourier-transform infrared spectroscopy (FTIRS), online differential electrochemical mass spectrometry (...

Electrochemical energy storage is considered a remarkable way to bridge the gap between demand and supply due intermittent renewable production. All-solid-state batteries are an excellent alternative known be safest class of batteries. In present scenario accomplish demands, high-capacity stable anodes warranted can play vital role in technology upgradation. Among variety anodes, alloying-type ...

Titanium dioxide is a very attractive material in catalysis. Although the titanium exhibits superior proper-ties ultra violet radiation, activity of catalyst can be improved by some modifications specially for daylight radiation. was colored thermal decomposition sodium borohydride at 400 0C. The gray nanotube-titanium obtained where molar ratio to borohydride, 1.2 and 0.6. black prepared makin...

We report that decomposition pathway of Ca(BH4)2 can be efficiently controlled by reaction temperature. That is, it decomposes into CaB6 at a lower temperature range of 320 to 350 °C, but into amorphous boron at 400 to 450 °C. We identified the formation of CaB2H6 as the crucial intermediate step on the way to CaB6 that only forms at 320 to 350 °C.
