Active surfactants are those that are responsive to an external stimulus, such as temperature, light, electric or magnetic fields or chemical agents. Scientists from the Institute for Basic Science (Daejeon, South Korea; www.ibs.re.kr) have developed surfactants based on functionalized nanoparticle…
It has been a challenge to find materials that can reliably detect volatile organic compounds (VOCs) and toxic gases in air at the parts-per-billion (ppb) level, or that can be used for therapeutic diagnosis from breath analysis. That’s because two…
Waste to chemicals A consortium of companies, including Air Liquide (Paris, France; www.airliquide.com), AkzoNobel Specialty Chemicals (Amsterdam, the Netherlands; www.akzonobel.com), Enerkem Inc. (Montreal, Canada; www.enerkem.com) and the Port of Rotterdam, has signed a project development agreement covering initial investments in…
Lithium-ion batteries based on intercalation compound electrodes exhibit poor performance at temperatures below 0°C. Insufficient ionic conductivity and freezing of the electrolyte are generally seen as the main reasons for the poor performance of rechargeable batteries at low temperatures. Although…
Using a simple, ligand-free palladium catalyst system, researchers at McGill University (Montreal, Que., Canada; www.mcgill.ca) have demonstrated that metal carbonylation — a core chemical reaction for many industrial products — can be used to synthesize ketones directly from hydrocarbons. The…
Last month, the so-called Hybrit initiative (www.hybritdevelopment.com) was given the go-ahead to build a pilot plant for making fossil-free steel. The announcement follows a pre-feasibility study conducted by Swedish partners SSAB AB (Stockholm; www.ssab.com), LKAB (Luleå; www.lkab.com) and Vattenfall AB…
The research group of professor Masafumi Hirando at Tokyo University of Agriculture and Technology (TUAT; Koganei City, Japan; www.tuat.ac.jp) has performed the world’s first one-pot synthesis of conjugated polyenes, which normally require at least seven steps by conventional methods. This…
Glycolic acid Researchers from the group of professor Miho Yamauchi at the International Institute for Carbon-Neutral Energy Research (I2CNER) of Kyushu University (Fukuoka City, Ito Campus, i2cner.kyushu-u.ac.jp) have fabricated a liquid flow-type electrolyzer that can continuously produce an alcohol from…
Last month, Genomatica (San Diego, Calif.; www.genomatica.com) and Aquafil (Trento, Italy; www.aquafil.com) announced a partnership to commercialize a Genomatica process for making caprolactam derived from renewable feedstocks, rather than from petroleum. The cyclic amide caprolactam is a key intermediate for…
In what is said to be the largest municipal wastewater application using peracetic acid (PAA) disinfectant to date, the Metro Wastewater Reclamation District in Denver, Colo. recently began disinfecting wastewater effluent with a PAA formulation from Enviro Tech Chemical Services,…
