An efficiency boost for solar hydrogen
The New Energy and Industrial Technology Development Organization (NEDO, Kawasaki, Japan; www.nedo.go.jp) and the Japan Research Association of Artificial Photosynthetic Chemical Process (ARPChem) achieved a world-leading solar-energy conversion efficiency of 2% in the photocatalytic splitting of water to make H2…
Micronized rubber powder improves polymer loadings
A new process for partially devulcanizing and functionalizing micronized rubber powders (MRP) may allow the use of higher levels of the material than originally allowed in vehicle tires and other applications. Currently, MRP from end-of-life rubber is being used in…
Making hydrogen directly from Si nanoparticles
A safe, low-cost technology for supplying H2 to fuel-cell powered vehicles is being developed by researchers at Nisshin Kasei Co. (Osaka, Japan; www.nisshinkasei.co.jp). Unlike alternative methods that store H2 by adsorption on solid materials at high pressure, Nisshin is utilizing…
Pilot plant slated for a fast-pyrolysis process that converts biomass into fuels
Plans are underway to build a pilot plant for a fast-pyrolysis process that will convert 10 ton/d of biomass into bio-oil and bio-char. The bio-oil can be used as renewable fuel oil or catalytically upgraded to transportation fuels, while the…
A smart app for pump monitoring
At Achema 2015 (June 15–19; Frankfurt, Germany), KSB AG (Frankenthal, Germany; www.ksb.com) will launch a new smartphone application (app) that enables non-specialists to quickly determine the power consumption of a pump during operation. Within seconds, the user can know if…
Smart polymers enhance coatings to reduce fouling
Scientists from Singapore, including Vivek Vasantha from A*STAR – The Agency for Science, Technology and Research (www.a-star.edu.sg) – developed a new block copolymer that can change its structure when placed in an electrolyte solution, such as salt water. The monomers…
Catalytic hot-gas filters reduce dust and pollutants
In late April, Unifrax I LLC (Tonawanda, N.Y.; www.unifrax.com) and Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) signed a partnership agreement to begin a joint global effort to commercialize an innovative new line of catalytic filter candles. This new product family…
Separating rare earth metals with UV light
Researchers from the Dept. of Chemical Engineering of KU Leuven (Belgium; www.cit.kuleuven.be), in collaboration with KU Leuven chemists, have discovered a method to separate two rare-earth elements — europium and yttrium — with ultraviolet (UV) light. The study, published earlier…
May Chementator Briefs
A natural fungicide An international research team, led by Yoshikazu Ohya at the University of Tokyo (www.ib.k.u-tokyo.ac.jp), has discovered a new chemical compound that inhibits the growth of pathogenic fungi. The new compound, called poacic acid, was isolated from hydrolyzed…
An effective graphene-based desalination membrane
Researchers from Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have demonstrated an efficient desalination process using a porous graphene-based desalination membrane. While the thinness of the freestanding graphene (roughly 0.3 nm) allows for significantly higher flux than traditional…
