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…
Shell Thiogro (www.shell.com/sulphur/thiogro) and Uhde Fertilizer Technologies (UFT; www. uhde-fertilizer-technology.com), part of thyssenkrupp Industrial Solutions AG (Essen, Germany), have established a partnership to integrate UFT’s fluidized-bed (FB) granulation technology with Shell’s Urea-ES (enhanced sulfur) technology, which was introduced in May…
A design-of-experiments (DoE) approach has resulted in better-performing fluids for metal grinding, cutting and machining applications. These fluids serve to lubricate cutting surfaces, remove heat, prevent corrosion and carry away fine particulates that can distort machined surfaces. In recent years,…
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 multi-company partnership has achieved the largest-ever use of molybdenum/tungsten (Schrock-type) catalysts for a metathesis process involving ethylene and renewable oils. The reaction run, which produced primarily 1-decene and 9-decenoic acid methyl ester from ethylene and plant oils, represented a…
Milliken & Co. (Spartanburg, S.C.; www. millikenchemical.com) has optimized its core clarifying technology for polypropylene (PP) resin to raise the clarity level to compete with that of polyethylene terephthalate (PET), polystyrene (PS) and polycarbonate (PC). The optimized technology allows the…
