This one-step route to cellulosic ethanol features a multitasking yeast
The research group of professor Akihiko Kondo at Kobe University (Kobe City, www2.kobe-u.ac.jp/~akondo/index_English.htm) has developed a one-step, pretreatment process for making bioethanol from cellulose and lignocellulose. The process uses an ionic liquid — which converts cellulose into a gel —…
Process for renewably sourced polyols licensed
A process for making polyols from soybean oil and glycerin has been licensed by its developer, Battelle (Columbus, Ohio; www.battelle.org), to Emery Oleochemicals Americas (Cincinnati, Ohio; www.emeryoleo.com), who intends to produce the renewably sourced polyols at prices similar to those…
Lightweight diamond aerogel
Researchers at Lawrence Livermore National Laboratory (LLNL; Livermore, Calif.; www.llnl.gov) have created a nanocrystalline diamond aerogel. The new aerogel was produced by compressing a standard carbon-based aerogel precursor in a laser-heated diamond anvil cell, which consists of two opposing diamonds.…
Rubber manufacturing process allows in-mold curing
Along with an innovative elastomeric compound, scientists at Federal Mogul Corp. (Southfield, Mich; www.federalmogul.com) have developed a rubber manufacturing process that eliminates the need for curing in a batch oven after molding. The proprietary compound, known as K16, is intended…
A platinum-free fuel-cell catalyst
A research team from Los Alamos National Laboratory (Los Alamos, N.M.; www.lanl.gov) has developed a novel catalyst for the cathode of a fuel cell that avoids using expensive ($1,800/oz.) platinum metal. The cathode catalyst is on based carbon, partially derived…
Biodegradation system for VOCs poised for expansion
A system that utilizes existing biological wastewater-treatment facilities for destruction of biodegradable volatile organic compounds (VOCs) and other organic hazardous air pollutants (HAPs) has been demonstrated at three U.S. petroleum-refining and chemical facilities, and the developer has plans to extend…
Low-cost process for bioethanol fuel demonstrated in Japan
Mitsubishi Heavy Industries Ltd. (MHI; Tokyo, www.mhi.co.jp) says it has established technology to produce bioethanol for automobile use by using soft-cellulose, such as wheat straw and rice straw, as raw materials. MHI estimates the fuel cost for a full-scale production…
A new way to grow functional MOFs
A team from CSIRO Materials Science and Engineering (Melbourne, Australia; www.csiro.au) has developed a new technique for growing smart materials known as metal-organic frameworks (MOFs), which can be used in pollution control, or as catalysts, or for transporting drugs in…
Commercial production of ‘Bio-cokes’
Last month, construction was completed on the world’s first commercial plant to produce a next-generation solid fuel, called Bio-cokes, at Takatsuki, Japan. The renewable material is produced from forest residues and can be used as an alternative to coal-based coke…
A comprehensive zeolite database
A team led by Rice University (Houston; www.rice.edu) researcher Michael Deem has assembled a database of 2.6 million possible unique zeolites — porous silicate minerals often used as catalysts or molecular sieves. The database of potential structures could inform efforts…
