Strength with stress Shear forces usually break bonds in polymer materials, but a research team at Duke University (Durham, N.C.; www.duke.edu) has demonstrated for the first time synthetic polymers capable of forming new bonds in the presence of shear…
A process from Dow Water & Process Solutions (DW&PS; Edina, Minn.; www.dowwaterandprocess.com) uses a unique adsorbent resin to improve the taste of orange juice. Amberlite FPX66 is a macroreticular, non-functionalized adsorbent resin with a pore structure designed to capture a…
Lactose has been widely used as a pharmaceutical excipient, where the size and morphology of the particles of lactose significantly affect the functionality of the resultant drug product. Lactose particles produced by various methods exhibit various morphologies, such as spherical…
Although the inactivation of bacteria by high-power ultrasound has been extensively studied, the relationship between the effectiveness of ultrasound to inactivate bacteria and their physico-chemical properties is not yet well understood, says Muthupandian Ashokkumar, professor at the University of Melbourne…
Launched this month at drinktec (Trade Fair for the Beverage and Liquid Food Industry; September 16–20; Munich, Germany), Eco-IcePush is a new technology for recovering products during equipment purging, and is being offered by GEA Process Engineering A/S (Søborg, Denmark),…
Many investigations are ongoing to achieve ammonia synthesis at energy-saving mild conditions instead of the high temperatures and pressures (500°C, 300 atm) required by the commonly used Haber-Bosch process, which consumes more than 1% of the world’s power production. Now,…
High fluxes and micro-contaminant reduction have been achieved in a 2.5-m3/h pilot plant to test the performance of ceramic membranes and ozonation in treating wastewater at Melbourne Water’s (www.melbournewater.com.au) Eastern Treatment Plant. The project, to be completed in a few…
Researchers from EMPA, the Swiss Federal Laboratories for Materials Science and Technology (St. Gallen, Switzerland; www.empa.ch) have developed organic phosphorous-containing compounds, called phosphoramidates, that show promise as non-toxic alternatives to conventional halogenated flame retardants, such as tri(chloropropyl)phosphate (TCPP) or polybrominated…
The petroleum refining sector in India plays a vital role in the country’s industrial development and provides a major source to meet India’s energy requirements. Today, the refining sector satisfies about 30% of the total energy demand of India […
Researchers from the U.S. Dept. of Energys Joint BioEnergy Institute (JBEI; Emeryville, Calif.; www.jbei.org) have reported the first demonstration of a one-pot, wash-free process for the ionic-liquid pretreatment and saccharification of switchgrass — a leading potential biofuel feedstock. By combining…
