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 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…
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 team from the Korea Advanced Institute of Science and Technology (Kaist; Daejeon, South Korea: www.kaist.ac.kr) and Seoul National University (www.useoul.edu) led by Kaist’s professor Keon Jae Lee, claims to have developed the first prototype of a fully functional all-flexible…
Professor Kenichoro Itami and his group at Nagoya University (synth.chem. nagoya-u.ac.jp) have synthesized a cage-type carbon nano-molecule, Carbon Nano-cage, composed of 20 condensed benzene rings — C120H78. The group used a procedure it developed four years ago to synthesize carbon…
Several drug delivery systems have been studied involving the encapsulation of molecules in a suitable structure and their transport through the human body. In particular, polymersomes — tiny hollow spheres that enclose a solution — formed using synthetic block copolymers…
A test method developed by SABIC (Saudi Basic Industries Corp.; Riyadh, Saudi Arabia; www.sabic.com) scientists drastically reduces the time needed to evaluate slow-crack growth resistance in high-density polyethylene (HDPE) that is used in pressure pipes. The strain-hardening test method allows…
Artificial photosynthesis Scientists at Panasonic Corp.(Osaka, Japan; www.pana sonic.com) have developed an artificial photosynthesis system that utilizes sunlight to convert CO2 to organic materials (mainly formic acid) at what is said to be the highest efficiency yet achieved (0.2%).…
A new hydraulically driven, positive-displacement-pump system can lower the energy requirements for pumping water by 10% in large seawater reverse osmosis (SWRO) desalination plants, where electricity typically represents the largest cost. Recently launched by GE Water & Power (www.ge-energy.com) at…
A move toward bio-based malic acid... Novozymes A/S (Copenhagen, Denmark; www.novozymes.com) has developed a strain of metabolically engineered Aspergillus oryzae fungus that is capable of producing the four-carbon, dicarboxylic acid compound malic acid. The chemical building block malic acid is…
