An isopropanolic extract of serum can be made suitable for the simultaneous estimation of cholesterol and triglycerides by passing it through a commercially-available chromatographic column containing activated metallic oxides in which alumina predominates. No centrifugation step nor phase separation is required. Use of the purified extract allows existing methods to be simplified and shortened...

Compact and defect-free high melting point oxide strengthened metallic matrix configurations are promising to resolve the hydrogen permeation brittleness issues relevant fusion research community. Previous studies on addition demonstrated a mitigation in behavior, while deposition techniques material still be investigated. Thus, here, we report structural, morphological, mechanical characteriza...

in this research, nano materials with tubular structures are added to sae 20w50 engine oil to study the rate of their effects on the properties of engine oil. multi-walled carbon nanotubes (mwcnts) and vanadium oxide nanotubes (vonts) has been used as two different additive materials, one of them is carbonic and the other is metallic oxides and their effect on  different parameters containing v...

The measurement of the heats of formation of organo-metallic compounds presents, usually, a difficult task to the experimental thermochemist. Thus the method of combustion in a conventional bomb-calorimeter, although it has been applied to a number of metallic alkyls in recent years! and yielded valuable results, is nevertheless not entirely satisfactory. The difficulty is that complete oxidati...

Two new oxides have been unambiguously identified as Bi2Tc2O7-delta with delta = 0.14(1) and Bi3TcO8 through X-ray absorption near-edge structure spectroscopy and neutron powder diffraction. The compound Bi2Tc2O7-delta has a cubic pyrochlore-type structure with a = 10.4746(1) A, space group Fd3m (origin choice 2), and Z = 8. The compound Bi3TcO8 is also cubic, a = 11.5749(1) A, space group P2(1...
