Haldor Topsøe (Lyngby, Denmark; edlinks.che.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and the Type II active sites (edge sites) for direct...

The Technical Research Center of Finland (VTT; Rajamäki; edlinks.che.com/5826-542) has developed a process to make natural paper additives from starch, which can be used for making high-quality paper that is completely recycleable. The starch-based pigments can be used in conventional papermaking processes instead of inorganic minerals (such as clay, talc, carbonates) for fillers, and instead of...

Using lithium metal as the anode of secondary Li-ion batteries would double the energy density of conventional batteries, which use anodes based on carbon. However, Li-based anodes suffer from the problem of dendrite crystal formation during the charge and discharge cycles of the battery. The needlelike projections of these dendrite crystals can result in short...

Last month, “Series C” funding in the plastic-electronics development company, Plastic Logic Ltd. (Cambridge, U.K.; edlinks.che.com/5825-537), reached $24 million, with the addition of investments from four new companies, including BASF Venture Capital GmbH (Ludwigshafen, Germany; edlinks.che.com/5825-538). Other companies that have previously invested in the firm include Dow Chemical (Midland...

A prototype of what is called the world’s fastest, wide-ranging hydrogen gas sensor has been constructed by a team of researchers, led by Professor Kazushi Yamanaka at the Dept. of Materials Processing, Tohoku University (Sendai, Japan; edlinks.che.com/5828-531), together with Toppan Printing Co. and Yamatake Corp. (both Tokyo) and support from Ball Semiconductor Inc., (Allen, Tex.). The sensor...
