  • Patent number: 9707251
    Abstract: Two siloxane-based mixtures combine to form a soft or semi-solid matrix for forming an artificial blockage to control bleeding, particularly moderate to severe bleeding. The first component includes a homogeneous mixture or solution that includes a polymeric matrix, a surfactant, filler(s) and metal compound(s). The second component includes a homogeneous mixture or solution that includes a polymer(s), a filler(s), a surfactant, and hydrogen peroxide. The combination of the two components is carried out with adequate mixing using mechanical and micro-kinetic mixing mechanisms and can be performed in a field-ready delivery device.

  • Publication number: 20160153094
    Abstract: A process to etch hierarchical, re-entrant texture into the surface of metals and their alloys using salt-based etching solutions. The process imbues superhydrophobic, oleophobic or superoleophobic, omniphobic or superomniphobic properties by further imparting a low surface energy coating onto the etched surfaces by chemical functionalization by low surface energy hydrophobilizing compounds.

  • Patent number: 7288672
    Abstract: The present invention relates to a process for the preparation of esters of hydroxy tiglic aldehydes which are the key intermediates for Vitamin-A acetate synthesis and various perfumistic products, said process relates to the hydroformylation of biscarboxylic esters of but-2-ene-1,4-diol, followed by deacetoxylation of its hydroformylation compound, in the presence of heterogeneous catalyst having rhodium complex entrapped, anchored or teethered on the acidic support, said acidic support causes deacetoxylation in the reaction mixture immediately after hydroformylation, to give 100% selectivity to the carboxylic esters of hydroxyl tiglic aldehydes in a single step.
