New material promises to enhance performance of gas-separation membranes
Harnessing its polymer technology and carbon-fiber expertise has enabled Toray Industries, Inc. (Tokyo, Japan; www.toray.com) to create a porous carbon fiber with uniformly continuous pores (diagram) — claimed to be a world’s first. Using this fiber as a support layer…
A Pt-free electrode promises to cut costs for fuel cells and metal-air batteries
Hiroya Abe and colleagues at Tohoku University (Sendai, www.tohoku.ac.jp) and Hokkaido University have developed a method to fabricate a highly active catalyst electrode for performing the oxygen reduction reaction (ORR) in fuel cells and metal-air batteries. Currently, such fuel cells…
Non-halogenated flame-retardant material
Dynamic Modifiers LLC (Atlanta, Ga.; www.dynamicmodifiers.com), a maker of custom polyolefin compounds, recently introduced PAL…VersaCHAR, a non-halogenated flame-retardant polymer designed to be molded over other materials. When exposed to flame, the formulation’s surface chars quickly, which prevents flame spread and…
Cascade reactions on ‘nanozymes’ make chemicals from CO2
An international team of researchers has developed metallic nanoparticles that imitate enzymes to convert carbon dioxide into ethanol and propanol, which are common raw materials for the chemical industry. The team includes professors Justin Gooding and Richard Tilley from the…
A new method to study nanoparticles
Researchers from the Singapore-MIT Alliance for Research and Technology (Singapore; https://smart.mit.edu) have discovered a way to study the properties of a nanoparticle without damaging it, which has not been possible so far. The work was led by Michael Strano, a…
