The phenyl lactam scaffold filling one of the subsites in the catalytic site, S4 pocket, with significant aromatic π-π stacking interactions, allows this frame to be invariably located with accuracy, because of the six membered lactam ring attached to an aromatic benzene ring. We anticipated that the addition of an alkyne unit would enable the exploration of the first section of S1 pocket, in this way producing a better molecule optimizing binding between our potential inhibitor and the active site of FXa. A fluorimetric assay was performed to determine IC50 values on the proposed molecules. All these findings were rationalized by docking energy delta and theoretical structure, vibrational and reactivity analysis to formulate a more accurate explanation about which structure has is the optimal inhibitor for this therapeutic target in the blood coagulation cascade.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"68 1","pages":"34-41"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84086727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mainly comprise chemical, semiconductor production, material industries etc. Separation of CO2 and other gasses from different materials, generating impurities and compromising material’s electrical and mechanical properties are of prime importance. CO2 absorption of a film flow of poly-ethylene terephthalate (PET) on a rotating disc is taken as a sample case for investigation through advanced computational fluid dynamics (CFD) modelling. A survey was conducted for different degrees of polymerization and angular velocities. The Volume of Fluid model (VOF) was used to measure the layer thickness of the molten PET, which can affect the mass transfer phenomenon. The profile of the concentration of CO2 was also investigated through user defined scalar (UDS) transport equations. This work is based on observation and investigation of the concentration profiles at different positions over the disc which emphasised the effects of the convective forces in the mass transfer phenomenon particularly at higher radial position. The results revealed that mass transfer of CO2 depends on the thickness of PET layer and fluid viscosity. It was also observed that convection transport strongly influences the rate of absorption over different disc positions.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"36 1","pages":"18-22"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75305772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transient pressure changes were measured and compared. The results of experiments show that: After the installing of the metal material, the peak value of the explosion pressure of the explosion is significantly reduced, indicating that the installing metal material can effectively inhibit the explosion of the combustible gas. It also can be seen that the magnetic metal materials nickel and iron have better inhibition performance than the non-magnetic metal material aluminum and copper in the gas explosion. And with the increase of the molecular weight and concentration of combustible gas, the explosion inhibition performance of magnetic metal materials become more obviously. The magnetic field effect of the magnetic metal can effectively affect the motion law of the free radicals during the explosion reaction, thus affecting the release of the explosive reaction energy.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"15 1","pages":"175-179"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76453709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
