Generation and Trapping of Ketenes in Flow
Ketenes were generated by the thermolysis of alkoxyalkynes under flow conditions, and then trapped with amines and alcohols to cleanly give amides and esters. For a 10 min reaction time, temperatures of 180, 160, and 140 °C were required for >95 % conversion of EtO, iPrO, and tBuO alkoxyalkynes, respectively. Variation of the temperature and flow rate with inline monitoring of the output by IR ...
متن کاملDehalogenation of trihalomethanes by a micro-alloyed aluminium composite under flow conditions
A new method for dehalogenation of trihalomethanes (THMs) by a low-cost and highly effective micro-alloyed aluminium composite (MAlC) in a semi-flow system (SFS) was studied. Addition of micro-alloyed elements significantly accelerated the rate of Al corrosion and enhanced reduction activity by destabilising the oxide film. THM dehalogenation by the MAlC followed pseudo first-order kinetics wit...

متن کاملEndothelial C-reactive protein increases platelet adhesion under flow conditions.
While data regarding the pathogenetic role of C-reactive protein (CRP) in atherothrombosis are accumulating, it is still controversial whether local CRP secretion is of any pathobiological significance. The present study examined whether endothelial-derived CRP modulates autocrine prothrombotic activity. Endothelial cells were isolated from hearts of mice transgenic to human CRP and grown in pr...
متن کاملUnder Blood Flow Conditions
A human ex vivo thrombosis model was used to investigate whether recombinant annexin V (rANV) can prevent thrombus formation under venous and arterial blood flow conditions. In this model, blood from an antecubital vein of healthy donors was allowed to flow directly over the extracellular matrix of tumor necrosis factor-stimulated endothelial cells (TNF-ECMs). TNF-ECMs were preincubated with rA...
