Researchers at the Faculty of Engineering, Lund University (Sweden; edlinks.chemengonline.com/7373-545) have used nanotechnology to develop a transistor that is said to be 50 times more energy efficient that conventional models. The prototype transistor is made of indium arsenide, where the…
Honeywell Specialty Materials (Morristown, N.J.; edlinks.chemengonline.com/7373-546) has launched PowerShield PV325, a material that protects photovoltaic (PV) modules — including the critical components that convert sunlight into electricity — in all types of environments. The material is ultraviolet, moisture and weather…
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…
At last month’s CosmoProf exhibition (April 10 – 14; Bologna, Italy), VMI-Rayneri (Montaigu, France; edlinks.chemengonline.com/7372-531) introduced a new vacuum-injection process for dispersing powder-like solids into liquids or pastes during the production of cosmetics, pharmaceuticals, food or other chemical products. Normally,…
The Jiashan Yao-chuang wastewater treatment plant in China’s Zhejiang Province has successfully pilot-tested a three-stage, biologically active reactor system that reduces effluent levels to within the nation’s Class 1A standards. (The standards require < 10 mg/L for biological oxygen demand…
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 process in which sulfur is extracted from natural gas in the field and converted to sulfur dioxide, which is then injected into the gas reservoir and reacts with hydrogen sulfide in situ to produce elemental sulfur, has been developed…
Verenium Corp. (formerly Celunol; Cambridge, Mass.; edlinks.chemengonline.com/7372-537) is starting up a 1.4-million gal/yr demonstration-scale facility at Jennings, La., which will produce ethanol from regional feedstocks (including sugarcane bagasse and specially bred "energy cane") via proprietary cellulosic-ethanol technology. The technology was…
