To date, determination of the shear forces exerted on vessel walls by moving fluids has required inferring the value from other measurements. Now Lenterra Inc. (Newark, N.J.; www.lenterra.com) has introduced the first instrument capable of direct measurement of wall-shear forces…
The Brinkman method is one of several approaches used to predict the effective viscosity of oil-water mixtures, and is effective in simulations when one or the other phase is dominant. However, a significant level of uncertainty exists in mixtures where…
New cellulase enzyme Last month, Codexis, Inc. (Redwood City, Calif.; www.codexis.com) introduced the CodeXyme Cellulase enzyme product line for converting biomass to sugar. The company is in its final stages of customizing the enzymes with currrent partners, and plans…
Gold catalysts have been shown to have superior activities for oxidation reactions, especially at low temperature, compared to other metal-based catalysts. But the high price of gold makes it necessary to develop Au catalysts with ever-higher activities, reducing the amount…
