These batteries can handle the cold

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…

A panel reactor for splitting water into hydrogen

A group of Japanese researchers have developed a photocatalytic panel reactor with large area (1 m2) that splits water into H2 and O2 using only natural sunlight. The NEDO (www.nedo.go.jp)-supported project — which includes partners Japan Technological Research Association of…

Catalytic conversion of sugars to acrylonitrile

Acrylonitrile (ACN) — a precursor in nearly all carbon fibers — is typically produced from propylene and ammonia, but a new method uses biomass-derived second-generation sugars. The process was developed by Southern Research (Durham, N.C.; www.southernresearch.org) and seeks to provide…

An explosive way to make porous organic networks

A team from Ulsan National Institute of Science and Technology (Ulsan, South Korea; www.unist.ac.kr), led by professor Jong-Beom Baek has introduced a synthetic methodology for fabricating a three-dimensional porous organic network with a high specific surface area via a solid-state…

These highly selective membranes mimic biological ion channels

New membranes developed at Tufts University (Medford, Mass.; www.tufts.edu) can effectively separate similar chemicals based on not only size but on electrostatic charge. “Currently, there are no commercial membranes that are designed to separate organic molecules of similar size but…

A more direct chemical route to ketones

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…

A push for ‘green’ steel

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…

‘One-pot’ synthesis of conjugated polyenes

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…

A bio-based caprolactam joint-development project is now underway

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…
