First theoretical analysis of the nuclear spin conversion in ethylene molecules

Application of Zeotype SAPO-34 Molecular Sieve as a Selective Adsorbent for Separation of Ethylene from Ethane

The process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. In this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. Effective separation techniques are required for separation of ethylene from unreacted ethane. Here a new adsorbent approach...

Design, Synthesis and Biological Evaluation of Novel Peptide-Like Analogues as Selective COX-2 Inhibitors

A new series of peptide-like derivatives containing different aromatic amino acids andpossessing pharmacophores of COX-2 inhibitors as SO2Me or N3 attached to the para positionof an end phenyl ring was synthesized for evaluation as selective cyclooxygenase-2 (COX-2)inhibitors. The synthetic reactions were based on the solid phase peptide synthesis methodusing Wang resin. One of the analogues, i...
