Chementator: New methods for solving differential equations
The behavior of many different phenomena can be modeled by systems of ordinary differential equations (ODEs), but most ODEs cannot be solved analytically, in which case an approximation to the solution is found by applying numerical integration methods. Dutch-sponsored mathematician…
Chementator: Non-invasive detector
Scientists at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory (Chilton, Didcot, U.K.; edlinks.chemengonline.com/7370-573) have developed a laser-based method for the characterization of the bulk-chemical content of pharmaceutical capsules — without opening the capsules. In collaboration with researchers…
Chementator: Grätzel cell
Researchers at the Fraunhofer Institute for Solar Energy Systems (ISE; Freiburg, Germany; edlinks.chemengonline.com/7370-575) have developed a solar-cell prototype that is semi-transparent, color-tunable and (thus far) resistant to weather degradation. A "classical Grätzel cell" according to Andreas Gombert head of Fraunhofer’s…
Chementator: Chiral synthesis
Scientists from the Center Biology at University College Dublin (Ireland; edlinks.chemengonline.com/7370-576) and the University of Bologna (Italy; edlinks.chemengonline.com/7370-577) have developed an enzymatic process that can be applied to the synthesis of chiral pharmaceutical intermediates. The researchers use an enzyme called…
Chementator: A push for Jatropha
Archer Daniels Midland Co. (ADM; Decatur, Ill.; edlinks.chemengonline.com/7369-547), Bayer CropScience AG (BCS; Leverkusen, Germany; edlinks.chemengonline.com/7369-548) and Daimler AG (Stuttgart, Germany) have signed a memorandum of understanding to explore the potential for a biodiesel industry based on Jatropha curcas L., a…
Chementator: Desalination barges based on reverse osmosis
Transfield Services Ltd. (edlinks.chemengonline.com/7369-549) and WorleyParsons Ltd. (both North Sydney, Australia; edlinks.chemengonline.com/7369-550) have been selected to construct two mobile-desalination units (MDU) for contingency use in the Brisbane River. The project is expected to provide 100-million L/d of potable water at…
Chementator: New ceramic-membrane system doubles rate and slashes cost for dehydrating ethanol
Hitachi Zosen Corp. (Hitz; Tokyo, Japan; edlinks.chemengonline.com/7369-531) is commercializing a new membrane for a hybrid-distillation system (HDS) that is especially suitable for dehydrating ethanol and isopropanol. The HDS can produce 99.7 vol.% ethanol from ethanol-water mixtures with 10 vol.% H2O…
Chementator: This platinum-free fuel cell runs on hydrazine
Daihatsu Motor Co., Ltd. (Osaka, Japan; edlinks.chemengonline.com/7369-532) has designed a fuel cell for powering automobiles, using nickel and cobalt for the electrodes (instead of conventional platinum and carbon), and hydrazine hydrate (N 2H4. H2O) as its fuel (instead of hydrogen).…
Chementator: Commercial production and debut of a new solid-acid catalyst for making biodiesel
Last month, Benefuel, Inc. (Mt. Prospect, Ill.; edlinks.chemengonline.com/7369-533) established an exclusive global agreement with Süd-Chemie India Pvt. Ltd. (SCIL; New Delhi) whereby SCIL will manufacture proprietary solid-acid catalysts for Benefuel’s biodiesel production facilities around the world. The patent-pending catalysts —…
Chementator: One less step to make activated carbon with dispersed metal nanoparticles
Nanostructured microporous carbons containing well-dispersed metal nanoparticles have the potential to improve the performance of fuel cells or catalysis. However, traditional techniques for embedding metal particles in porous carbons (post-synthesis treatment either by impregnation, adsorption, or ion exchange) can lead…
