Tiny sensors tucked into cell phones could map airborne toxins in real time


A tiny silicon chip that works a bit like a nose may one day detect dangerous airborne chemicals and alert emergency responders through the cell phone network. If embedded in many cell phones, its developers say, the new type of sensor could map the location and extent of hazards like gas leaks ...

Going off on a tangent


Ji-Woong Park, Jae-Suk Lee and colleagues from the Gwangju Institute of Science and Technology, investigated the structures formed when amphiphilic rod-coil block copolymers were dissolved in a solvent specific for the rod block of the copolymer. Park and colleagues have discovered that placing ...


Facile synthesis of nanoparticles with multiple functions advanced in Singapore

Metals that dissolve in water successfully extracted, transferred into layer of organic solvent that floats on water


Nanostructured materials have garnered great interest worldwide due to their unique size-dependent properties for chemical, electronic, structural, medical and consumer applications. Singapore's Institute for Bioengineering and Nanotechnology (IBN) has discovered a new environmentally friendly ...


Ruthenium in a clinch

Selectively and under mild conditions: Primary amines from alcohols and ammonia with a ruthenium catalyst


Amines are needed for the production of pharmaceuticals, fine chemicals, agrochemicals, plastics, dyes, pigments, and additives. Most important are compounds with a terminal amino group (–NH2), known as primary amines. However, the selective synthesis of primary amines remains a challenge. David ...


University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures


Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate." Researchers took advantage of the elastic instability of a widely used, ...


For Clean Air

Porous manganese oxide garnished with gold nanoparticles removes volatile organic compounds from air and breaks them down


In addition to nitrogen oxides and sulfur oxides, many volatile organic compounds (VOCs) in air contribute to smog and high ozone levels, as well as potentially damaging human health. Clean-air laws are thus rightly continuing to become stricter. Most modern air-purification systems are based on ...


Uhde to build turnkey plant for Ruhr Oel refinery in Germany


Ruhr Oel GmbH, represented by the operating company BP Gelsenkirchen GmbH, has commissioned Uhde to design and build a turnkey plant for reformate separation at their refinery site in Gelsenkirchen, Germany. The scope of services will include the extended basic engineering, detail engineering, ...


Aromatics plant based on innovative Uhde technology successfully commissioned for ARAL Aromatics


Uhde has gained yet another important reference in the field of refining technologies in successfully commissioning an aromatics plant for ARAL Aromatics GmbH in Gelsenkirchen, Germany. The plant is based on the improved Uhde Morphylane® process, by means of which high-purity toluene is produced ...


Measurement of lower aldehydes especially acrolein with the 2-HMP method - GC method


Guideline 3892 Part 5 describes a method for the determination of lower aldehydes especially acrolein (2-propenal) in waste gases of e.g. firing plants (especially wood firing), of internal-combustion engines or smokehouses as well as of foundries or chemical productions. The present Guideline ...


Showa Denko and Kyowa Hakko Starts up New Ethyl Acetate Plant


Japan Ethyl Acetate Co., Ltd., a joint venture established by Showa Denko K.K. and Kyowa Hakko Kogyo Co., Ltd. in August 2003, held a ceremony at SDK's Oita Petrochemical Complex to celebrate the smooth start-up of the JV's new 100,000-ton-a-year ethyl acetate plant. Demand for ethyl acetate ...
