Pannexin1 (Panx1) forms ATP channels that play a critical role in the immune response by reinforcing purinergic signal amplification in the immune synapse. Platelets express Panx1 and given the importance of ATP release in platelets, we investigated Panx1 function in platelet aggregation and the potential impact of genetic polymorphisms on Panx1 channels. We show here that Panx1 forms ATP relea...

A comparison of adsorption efficiency of the three Granular Activated Carbon (GAC) produced from waste Nigerian Bamboo at different level of activation in a fixed adsorption bed is reported. Bamboo carbonization was done at temperature range of 200-400c and chemically activated at 400c with chloride salt at percentage range of 0-20%. The 0, 10 and 20% level activation were selected for water tr...

Pectin rich fruit juices need enzymatic treatment for clarification. As fruits are rich in pectin, pectinolytic treatment can efficiently reduce viscosity resulting in clarified fruit juice. Enzymatic treatment of mango pulp results in 80% recovery of total juice present in the fruit. Use of pectin degrading polygalacturonases increases both fruit juice extraction and clarification. Polygalactu...

Amorphous hydrogenated carbon films were prepared by hot filament Plasma Enhanced Chemical Vapor Deposition using acetylene as precursor. NiP-coated Al substrate was sputtered with thin layer of ruthenium film prior to carbon deposition for its impact on carbon film growth. Film thickness measured and fitted using X-ray Reflectometry showed carbon film growth is an exothermic reaction with appa...

Tracers are needed for the development of high-temperature geothermal resources. Several candidate tracers have been tested for that purpose in hydrothermal autoclaves at the Energy & Geoscience Institute in Salt Lake City, Utah. One gas tracer, SF6, and two of the two-phase tracers, the straightchain alcohols, were tested. They were tested at temperatures ranging from 220 to greater than 300C,...

Pt wires were fabricated by using electron-beam (EB) and Ga focused-ion-beam (FIB) irradiation while providing C5H5Pt(CH3)3 gas through a nozzle. Electron transport properties of the wires were investigated. The resistance of the EB-deposited wires was quite high as deposited but was reduced by 3–4 orders of magnitude after 400–500C annealing. The electron transport of the as-deposited EB-depos...

The effect of flux angle, substrate temperature and deposition rate on obliquely deposited germanium (Ge) films has been investigated. By carrying out deposition with the vapor flux inclined at 87 to the substrate normal at substrate temperatures of 250C or 300C, it may be possible to obtain isolated Ge nanowires. The Ge nanowires are crystalline as shown by Raman Spectroscopy.
