    Abstract: The objective of this work is to design new compounds more active against SARS-CoV-2. This design study of new inhibitors on the main protease source of coronavirus (3CLpro) was conducted on ten molecules using Molecular Modeling techniques (Docking, QSAR, ADMET). Molecular docking between M5, M8 and M1 showing best, medium and low scores respectiv... Show More

    Abstract: Natural gas hydrate is an important potential energy source. Hydrates are easy to decompose at room temperature and pressure. In this paper, the laser Raman technology is used to quickly detect mixed gas hydrates at room temperature. The spectral characteristics show that: (1) The peak area ratio of the Raman spectrum is analyzed to obtain the mixe... Show More

    Abstract: A novel synthesis of 2-oxazolines from diketene by using DAST via Beckmann rearrangement as been described. The route involves a one-pot amidation of diketene with different amines at 70°C in the presence of toluene to form corresponding amides followed by reacting the amides with K2CO3 and DMF at room temperature to form corresponding carboxamides...
