Normally, only the ultraviolet (higher energy) component of the solar spectrum is usable for the photo-catalytic electrolysis of water into hydrogen and oxygen, which takes place in photochemical cells with an anode made of single-crystalline, rutile-type titanium oxide and a…
Researchers at Oxford Catalysts Ltd. (Oxford, U.K.; edlinks.chemengonline.com/7372-534) have shown that the method of preparation — rather than the identity or combination of metals used — has the greatest influence on the performance of hydrodesulfurization (HDS) catalysts. The results of…
A new roll-to-roll manufacturing process promises to overcome the major cost barriers impeding the widespread adoption of high-performance organic light-emitting diodes (OLEDs) for lighting, e-paper and display applications. The culmination of a four-year, $13-million research partnership between GE Global Research…
Because parts made from boron carbide have a higher rigidity and lower weight compared with those made from silicon carbide and alumina, boron carbide parts are important components for semiconductor manufacturing equipment and other components requiring high-temperature and abrasion resistance,…
Photovoltaics manufacturer Konarka Technologies, Inc. (Lowell, Mass; edlinks.chemengonline.com/7372-546) has successfully performed the first use of drop-on-demand inkjet printheads for the fabrication of organic solar cells. Using a Dimatix Materials Printer (DMP) provided by Fujifilm Dimatix (edlinks.chemengonline.com/7372-547), Konarka’s process suggests an…
Last month, Henkel KgaA (Düsseldorf, Germany; edlinks.chemengonline.com/7372-552) introduced a new conversion coating process called TecTalis, which replaces zinc phosphate, thereby offering "significantly" reduced cost and environmental footprint, says the firm. The new technology is easily applicable in existing lines. The…
IQTex (Hamburg; Germany; edlinks.chemengonline.com/7372-553) has developed a ventilation element — integrated into the soles of shoes — that functions like a flower, which closes up in the rain and reopens when dry. As a result, stepping in a puddle causes…
Demands in the chemical processing industry to reduce energy consumption and carbon footprint are higher than ever before. Correct sizing and selection of vacuum systems can contribute significantly to optimizing throughput and efficiency, thus reducing energy consumption, capital and running…
Unidym, Inc., (Menlo Park, Calif.; edlinks.chemengonline.com/7371-549) has entered into a joint development agreement with Nippon Kayaku (Tokyo, Japan; edlinks.chemengonline.com/7371-550), to integrate their printable transparent electrodes into the Japanese firm’s thin-film photovoltaic cells. It’s expected that Unidym’s transparent, carbon-nanotube-based electrodes (…
GEMÜ GmbH & Co. KG (Ingelfingen-Criesbach, Germany; edlinks.chemengonline.com/7371-551) has developed a new EPDM diaphragm for use at high temperatures and steam for the biotechnological and pharmaceutical industries. Service life is said to be up to three times longer compared to…
