High-performance polymers can compete with metallic systems in harsh processing environments and may offer potential benefits ...

State Key Laboratory of Petroleum Molecular & Process Engineering, School of Chemistry and Molecular Engineering, East China Normal University, Shanghai 200062, China Shanghai Key Laboratory of Green ...

Lipid content was determined gravimetrically after extraction with petroleum ether. Ash weight was measured after combusting samples at 550°C. Protein content was calculated as the difference between ...

These aromatic extracts are produced as by-products during the refining of crude oil. These DAEs can be blended to make other petroleum substances. Due to their untreated nature, these substances have ...

A short and efficient synthesis of heptadeuterated 2,2,4,4,5,7,7-d7-cholestane (1) from cholesterol (3) is described. The deuterated material will be useful for the analysis of different sources of ...

Furthermore, the obtained mass spectra agree with their in silico prediction by CFM-ID 4.0, (50) which also proposed the product ion structure for the most intensive masses. Fourier-transform infrared ...
