Nitrogen fixation The research groups of Yoshiaki Nishibayashi at the University of Tokyo (Japan; park.itc.u-tokyo.ac.jp/nishiba) and Kazunari Yoshizawa at Kyushu University (Fukuoka, Japan; trout.scc.kyushu-u.ac.jp/yoshizawaJ/indexe.html) have demonstrated the production of silylamine [N(SiMe3)3] from nitrogen gas using an iron-based catalyst. The reaction…
This pipe-cladding process applies corrosion-resistant coatings faster
The surface engineering company MesoCoat, Inc. (Euclid, Ohio; www.mesocoat.com) recently started up a facility for manufacturing clad pipe for the oil-and-gas industry that uses the company’s proprietary fusion-cladding technology to apply corrosion-resistant alloys to carbon-steel pipes. Because the cladding can…

Soy polyurethanes Scientists at Battelle (Columbus, Ohio; www.battelle.org) have developed a water-based polyurethane (PU) that uses soy oil instead of petroleum to produce the polyol precursor. Whereas standard water-based PUs require adding N-methyl-2-pyrrolidone (NMP) tolower viscosity, Battelle's process eliminates…
A low-cost route to ultrathin Pt films
Researchers at the U.S. National Institute of Standards and Technology (NIST; Gaithersburg, Md.; www.nist.gov) have developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms onto a surface. The technique may lead to a…
Nanoparticles help generate hydrogen
A research team is using clusters of gold atoms at sub-nanometer sizes to enhance the photocatalytic production of hydrogen from water. Sustainable H2 production from a non-fossil-fuel source could have significant environmental and energy-efficiency benefits. The scientists, from Stony Brook…
Scale up planned for a new CO2-capture process
Plans are underway to field-test a process that removes more than 90 % of the carbon dioxide from power-plant flue gas, while reducing both the energy input and operating costs by 50 % compared to conventional amine-based CO2-scrubbing technology. The…
Membrane reactor may reduce wastage of natural gas
A small-scale ceramic membrane reactor to convert natural gas to transportable liquids in a single step is being developed by Ceramatec, Inc. (Salt Lake City, Utah; www.ceramatec.com) under a $1.7-million grant from the U.S. Dept. of Energy’s Advanced Research Project…
Using sunlight to incorporate CO2 into alpha-amino ketones
The research group of Masahiro Murakami at Kyoto University (Kyoto, Japan; www.sbchem.kyoto-u.ac.jp/murakami-lab) have synthesized a promising pharmaceutical precursor using only sunlight (as energy source) and CO2 (as co-reagent). The solar-driven process involves two consecutive reactions (diagram): first, light transforms an…
A starch-based cationic polymer for oil recovery
Cationic polymers have been used in the petroleum industry as shale-control agents, demulsifiers, blocking agents, and filtrate reducers for drilling fluids, but process complexity and high cost have limited their application. Now researchers from Zhejiang Normal University (Jinhua; www.zjnu.edu.cn) and…
A step towards artificial photosynthesis
A photocatalyst that reduces CO2 into carbon monoxide is being commercialized by Tokyo Chemical Industry Co. (Tokyo, Japan; www.tcichemicals.com/en/jp/index.html). Developed by Osamu Ishitani and his research group at Tokyo Institute of Technology (TiTech; Japan; www.chemistry.titech.ac.jp/~ishitani/index-jp.htm), the catalyst is a step…
