A novel food-packaging material that is free from chemical additives and that can slow down fungal growth — doubling the shelf-life of perishable foods — has been developed by researchers from the National University of Singapore (www.nus.edu.sg). The researchers used…
Researchers at the Massachusetts Institute of Technology (MIT; Cambridge, Mass.; www.mit.edu) have demonstrated a two-stage process to convert synthesis gas (syngas) into lipids that can be used in biodiesel production. Eventually, such a process could be used to convert waste…
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…
The field of additive manufacturing (AM) — often referred to as 3-D printing — has seen explosive growth in recent years (Chem. Eng., February 2015, pp. 20–23; www.chemengonline.com/3-d-printing-accelerates-creating-cpi-opportunities). In AM, no tools or molds are required to shape the desired…
The research group of Ayumi Minoda at the University of Tsukuba (Japan, plmet.biol.tsukuba.ac.jp) has discovered that the cellular surface layer of the sulfothermophilic red algae, Galdieria sulphuraria, can efficiently adsorb gold and palladium ions, even in highly acidic conditions. G.…
Research groups at Keio University (Hiyoshi; www.bio.keio.ac.jp/labs/kmiyamoto) and Kyoto Institute of Technology, in collaboration with Teijin Ltd. and Adeka Corp., have discovered a bacterium that can degrade and assimilate poly(ethylene terephthalate) (PET), and have clarified the decomposition mechanism. This is…
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…
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…
