New catalysts for Baeyer-Villiger oxidation reactions

Kazuaki Ishihara and his group at Nagoya University (Japan; www.ishihara-lab.net) have established a new, environment friendly reaction technology — using Baeyer-Villiger oxidations — for selectively oxidizing ketones into esters. The reaction uses hydrogen peroxide as the oxidant, and has potential…

A little gold can reduce the Pt loading in fuel cells

A challenge in the development of polymer-electrolyte membrane fuel cells is the durability and electrocatalytic activity of platinum-based electrocatalysts. The sluggishness of the oxygen reduction reaction (ORR) causes the fuel cell performance to be limited by the cathodic reaction, and…

Save energy (and more) with this hybrid compressor system for EOR

Last month, Lewa GmbH (Leonberg, Germany; www.lewa.de) and Burckhardt Compression AG (Winterthur, Switzerland; www.burckhardtcompression.com) signed an agreement to commercialize hybrid compression systems for enhanced-oil-recovery (EOR) applications. EOR — injecting high-pressure CO2 into oil wells to both reduce the crude oil’s…

A commercial move toward algae farming for CO2 recovery

Advanced Algal Technologies (Sydney, Australia; www.advancedalgal.com) has signed a $100-million deal with Fuzhou Xiangli Enterprise Management Consulting (Fuzhou, China) — an LED-lighting manufacturer — for a license to build 500 algal-farming-conveyor modular units per year. These units will be used…

Sterile ice fog improves control of freeze-drying

Linde Gases (Murray Hill, N.J.; www.linde-gases.com) has developed a novel cryogenic technology that promotes uniformity in the formation of ice crystals during freeze-drying (lyophilization) processes for proteins, vaccines and other injectable pharmaceutical products. Lyophilization involves freezing a solution of the…
