This portable pesticide detector offers a quick check of produce
A micro portable pesticide detector for food analysis, called a Handheld Pesticide Residue Detector, has been developed by the Smart Microsystems Technology Center of the Industrial Technology Research Institute (ITRI, Hsinchu City, Taiwan; www.itri.org.tw). The detector is based on the…
This hybrid power-generation system combines SOFC and a gas turbine
Last month, Mitsubishi Hitachi Power Systems, Ltd. (MHPS; Yokohama, Japan; www.mhps.com) launched a new, pressurized, hybrid power-generation system (photo) that integrates solid-oxide fuel cell (SOFC) stacks with micro gas turbines (MGT). The hybrid system (diagram) has a broad range of…
Ammonia as a H2 carrier enabled by a catalytic membrane
A major challenge in using hydrogen to power motor vehicles is the difficulty in transporting H2 to refueling stations. Researchers at CSIRO Energy (Melbourne, Australia; www.csiro.au/energy) have responded to the challenge by converting H2 to NH3 and then using existing…
Winning iron and titanium while making vanadium electrolyte
VanadiumCorp Resource Inc. (Vancouver, B.C., Canada; www.vanadiumcorp.com) has achieved direct and consistent recovery of vanadium electrolyte, vanadium oxides and titanium from vanadiferous titanomagnetite (VTM; vanadium-rich Fe3–xTixO4) using hydroelectricity, from the company’s Lac Dore Vanadium Project in Quebec. The company has…
Oxy-fuel burner restores air-fuel regenerative furnaces to full production
Engineers at Air Products (Lehigh Valley, Pa.; www.airproducts.com) have commercialized an improved version of the company’s Cleanfire ThruPort oxy-fuel burner for avoiding downtime during repairs and extending the lifetime of air-fuel regenerative furnaces in glass-making plants. The company’s original Cleanfire…
Carbon nanotube technology toughens carbon-fiber composite materials
Under mechanical stress, carbon-reinforced epoxy-resin composite materials can experience cracking and de-lamination at the junctures between layers of material, where the composites are resin-rich. Placing vertically aligned carbon nanotubes (VACNTs) into the inter-laminar regions can toughen the composite and prevent…
Dual-functioning MOFs maintain a comfortable room humidity
Researchers from the King Abdullah University of Science and Technology (KAUST; Thuwal, Saudi Arabia; www.kaust.edu.sa) have developed a metal-organic framework (MOF) material that can regulate the humidity levels within the “window” established by the American Society of Heating, Refrigeration and…
Magnetized viruses attack challenging bacteria in water-treatment systems
Biofilms in water-treatment systems may harbor problematic bacteria and pathogens since chemical disinfectants typically do not penetrate the biofilm. Now, a new treatment approach developed in the laboratory of Pedro Alvarez at Rice University (Houston; www.rice.edu) could enable the controlled…
Bioethanol from bagasse
Tsukishima Kikai Co. (www.tsk-g.co.jp) and JFE Engineering Corp. (both Tokyo, Japan; www.jfe-eng.co.jp) have demonstrated a process that produces bioethanol from bagasse, a waste product in the production of sugar from sugarcane. With support from NEDO under a four-year, $10-million project,…
A new zeolite catalyst promises to significantly improve naphtha cracking
Chiyoda Corp. (Yokohama, www.chiyoda-corp.com) has been working on a new naphtha cracking process with the aim of producing more propylene and consuming less energy than existing naphtha thermal-cracking methods. The company has recently developed a new catalyst based on iron-…
