Researchers from the University of Wollongong (Australia; www.uow.edu.au), led by professor Gordon Wallace and Caiyun Wang, built a battery with electrodes and a solid electrolyte out of silk. Previous attempts at making such biodegradable, dissolvable batteries used natural, biocompatible materials…
Many ZnO@TiO2 core-shell nanorod arrays (the notation means ZnO is the core inside the TiO2 shell) with good photocatalytic activity have been designed and synthesized. There has been an increasing interest in the design and synthesis of those arrays to…
Carbon fibers, an increasingly essential component for lightweight materials, are typically made from polyacrylonitrile (PAN) in a three-step process consisting of oxidation/stabilization, carbonization and surface treatment/sizing. 4M Industrial Oxidation, LLC (Knoxville, Tenn.; www.4mio.com) intends to commercialize a technology to produce…
An international group of researchers, coordinated by the Institute of Solar Research of the German Aerospace Center e.V. (DLR; Cologne, Germany; www.dlr.de), is developing a sulfur-based storage system for solar power. Large-scale chemical storage of solar power and its overnight…
Construction has been completed on a 1,000-ton/yr facility to produce surfactants — mainly sucrose esters for use as additives in dairy products and beverages. The plant will be operated by TMT Co. — a joint venture (JV) established by Microwave…
Polymer electrolyte membrane fuel cells (PEMFCs) running on hydrogen are an attractive proposition, particularly as a power source for motor vehicles. In situ release of the required H2 from a stable liquid ensures its safe storage and transportation before use.…
A new fuel-upgrading catalyst for petroleum refineries has several features that boost sustainability and minimize environmental impact. In March, specialty chemical maker Clariant (Muttenz, Switzerland; www.clariant.com) launched PolyMax 850, a new generation of its PolyMax catalyst series. The new catalyst,…
Biopharmaceutical companies — especially those involved in manufacturing vaccines — spend a lot of effort and money to remove host cell nucleic acid (DNA and RNA) impurities from fermentation batches. The total downstream processing costs can account for up to…
Graphene-oxide-based materials are lamellar carbon compounds that are approximately 1-nm thick, and are expected to show excellent properties for various functional materials, such as innovative battery materials, lubricants, water-treatment membranes and catalysts. However, because these materials have been synthesized by…
China has successfully brought onstream the world’s first demonstration plant that converts coal to ethanol, according to an announcement by the Chinese Academy of Sciences. Located at Shaanxi Yanchang Petroleum in China’s Shaanxi province, the plant uses process technology that…
