This company’s double planetary mixers are now available with a slightly tilted configuration of the stirrers to effect more effective and complete discharge of flowable products. Double planetary mixers are used in the preparation of pastes and gels, as well…
Two dissimilar iron-making methods — a conventional blast furnace using coke from coal, and gas-based direct reduction of iron ore — are combined in a process being developed by Midrex Technologies, Inc. (Charlotte, N.C.; www.midrex.com) and Praxair Inc. (Danbury, Conn.;…
Transfinity elastomer composite products specifically are designed for use in anti-vibration applications. These products provide elastomer compound formulators the flexibility to control damping levels and achieve the highest levels of dynamic durability. This new flexibility in material formulation creates opportunities…
A system that continuously produces 10 ton/yr of nanoparticles has been developed by Tadafumi Adschiri, principal investigator at the Advanced Institute for Materials Research (AIMR) and professor at the Institute of Multidisciplinary Research for Advanced Materials and New Industry Hatchery…
The production rate (per amount of catalyst) for generating liquid hydrocarbons from syngas by the Fischer-Tropsch (F-T) process, using a slurry reactor or tubular reactor, is generally limited to about 30% of the maximum rate. The restraining factor is heat…
Petroleum-derived ethylene normally contains traces of acetylene, which interferes with the conversion of ethylene into polyethylene (PE). Because it is difficult to separate it, the acetylene is selectively hydrogenated to ethylene — without subsequent hydrogenation to ethane — using a…
Ajinomoto Co., Inc. (www.ajinomoto.com) and Bridgestone Corp. (Both Tokyo, Japan; www.bridgestone.com) have jointly developed a bio-based, high- cis-polyisoprene synthetic rubber. The two companies began an R&D cooperation in June 2011 to combine their know-how — Ajinomoto’s state-of-the-art fermentation technologies for…
A tube welder for sterile biopharmaceutical applications Sartorius Stedim Biotech The Biowelder Total Containment (TC) system features innovative technology that permits sterile connection of liquid-liquid thermoplastic tubing that has an outer diameter of up to 1 in. and that is…
The research groups of professor Yasuyuki Tsuji and assistant professor Tetsuaki Fujihara at Kyoto University (Japan; www.ehcc.kyoto-u.ac.jp) have developed a copper-catalyzed reaction for synthesizing carboxylic acids, such as acrylic acid, using carbon dioxide as a raw material. The reaction involves…
A group of scientists from Fudan University (Shanghai, China; www.fudan.ac.cn) China, has reported what it claims to be the first example of artificial single-molecular water channels that can transport water across lipid membranes. Transmembrane water transport — through water channel…
