A Korean team, headed by professor Sang Yup Lee of the Korea Advanced Institute of Science and Technology (Daejeon, South Korea; www.kaist.ac.kr), has obtained various forms of PLGA [poly(lactate-co-glycolate)] from natural sources, allowing plastics to be made in an environmentally…
Fe-free HTS catalyst Last month at the Nitrogen + Syngas 2016 conference (Berlin, Germany; February 29–March 3), Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) introduced SK-501 Flex, a new high-temperature shift (HTS) catalyst with the unique ability to operate at any…
Conventional catalytic converters in automobiles are based on heterogeneous catalyst systems with precious metals (such as Pt and Pd), rare earth elements and Ce (in the form of CeO2). However, the cost and limited resources of such metals is driving…
Professor Hisao Hori and his research group at Kanagawa University (Hiratsuka City, Japan; www.kanagawa-u.ac.jp) have reported what is said to be the first photo-induced recovery of rhenium from aqueous solutions — an achievement with implications for an inexpensive way to…
A process for the separation and recovery of stranded and associated natural gas is being developed by Framergy, Inc. (Wilmington, Del.; www.framergy.com), with support from the National Science Foundation’s Small Business Innovation Research (SBIR) Phase I program. The company is…
A recently introduced heat-transfer fluid is made from corn sugar, rather than from petroleum. Known as So-Blu, the fluid was developed through a joint effort of Dupont Tate & Lyle BioProducts (Loudon, Tenn.; www.duponttateandlyle.com) and SolarUS Inc. (Branford, Conn.; www.solarus.com),…
A scalable technology for allowing the cost-effective manufacture of superhydrophobic metallic coatings has been demonstrated in the laboratory. The method could have applications for heat exchangers, condensers, high-temperature and high-conductivity applications and other types of equipment. The startup company Maxterial…
Vigorous microbial growth in bioreactors raises cell density, which is a source of heat stress and can hinder production efficiency. To address the issue, scientists have tried introducing genes for heat-shock proteins (HSPs) into workhorse industrial bacteria like Escherichia coli,…
Light olefins, such as ethylene and propylene, are primarily made by the catalytic cracking of crude oil. Alternatively, two other methods were developed during the time of high oil prices, both of which convert synthesis gas (syngas) to olefins: the…
The first commercial-scale, natural-gas-fermentation facility in the U.S. will break ground by the end of 2016, according to Alan Shaw, CEO of Calysta Inc. (Menlo Park, Calif.; www.calysta.com). In a collaboration with agricultural giant Cargill Inc. (Minneapolis, Minn.; www.cargill.com), Calysta…
