Last month, Krohne Messtechnik GmbH (Duisburg, Germany; www.krohne.com) launched SmartSens, the first family of two-wire, loop-powered analytical sensors with integrated transmitter technology. Prior to this, analytical sensors have required an external proprietary transmitter onsite to deliver the sensor signals to the process control system. Krohne has...

Two new coating products for sand proppants used in hydraulic fracturing operations in the oil and gas industry overcome the challenges of traditional phenolic coatings, which can leach environmentally hazardous chemicals. The coatings, developed by Preferred Sands LLC (Radnor, Pa.; www.preferredsands.com), are based on a specialized polyurethane developed over the past three years with partner The Dow...

Researchers from the group of Atsushi Fukuoka at the Catalysis Research Center of Hokkaido University (Sapporo; www.cat.hokudai.ac.jp), and Showa Denko K.K. (SDK; Tokyo, both Japan; www.sdk.co.jp) have developed a new catalyst that efficiently decomposes biomass into sugars. The activated-carbon-based catalyst achieves high yields of both C6 and C5...

The research groups of Keiichi Fujishige at Tohoku University (Sendai, www.che.tohoku.ac.jp/~erec) and Daicel Corp. (Osaka, both Japan; www.daicel.com) have developed a process for making 1,3-propanediol (1,3-PDO) from glycerin, a byproduct of biodiesel-fuel production. The researchers improved a catalyst developed by Fujishige to be applied to a rather simple reaction process. They are expecting that...

Heap-leaching for REs Studies conducted by Texas Rare Earth Resources Corp. (Sierra Blanca, Tex.; www.trer.com) indicate that heap leaching with 15% (~150 g/L) sulfuric acid has the potential to dissolve minerals containing rare-earth (RE) elements from host rock at an RE mineral site near El Paso, Texas. Research conducted by the heavy RE exploration company on the minerology, geochemistry and...

The Circa Group (Melbourne, Australia; www.circagroup.com.au) and the Green Chemistry Center of Excellence at the University of York (U.K.; www.york.ac.uk) have signed an agreement to develop and commercialize a novel “green” solvent called Cyrene. Cyrene is a polar aprotic solvent — a solvent that lacks an acidic hydrogen and has a high dielectric constant and a high dipole moment...

The first commercial application of a newly developed process for the treatment of oxides of nitrogen (NOx) waste gas has been established at a milling operation in Los Angeles, Calif. Developed by Pacific Rim Design and Development (PRDD; Reno, Nev.; prdd.net), along with DuPont (Wilmington, Del.; www.dupont.com), the process uses gas-phase chlorine dioxide to react with both NO and NO2 to form nitric and...

Last month, Air Products (Allentown, Pa.; www.airproducts.com) announced that it has licensed its proprietary adsorption-based, monomer recovery process to custom process equipment supplier Cryo Technologies (Allentown, Pa.; www.cryotechnologies.com). The hybrid Air Products technology combines a partial condensation unit with a pressure-swing adsorption (PSA) process to recover unreacted ethylene and...

A team of researchers from Novasep (Pompey, France; www.novasep.com) has discovered and characterized the explosive properties of the so-called Togni reagent II and intermediates at the Novasep Leverkusen site in Germany. Invented by professor Antonio Togni at the Laboratory of Inorganic Chemistry, ETH Zürich (Switzerland; www.eth.ch) Togni reagent II...

A newly launched gas chromatography (GC) device from Analytical Pixels Technology (APIX; Grenoble, France; www.apixtechnology.com), called GCAP, uses a nanoscale silicon-beam resonator to detect mass. A piezoelectric cross-beam initiates the vibration of the nanoscale silicon resonator, and the resonance frequency varies with the mass in contact with the silicon resonator. Because GCAP’s architecture...

Ken-ichi Tominaga and colleagues at the National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba, Japan; www.aist.go.jp) have developed a hybrid catalyst system that can be used to convert cellulose into levulinic acid. The catalyst consists of two types of acid: indium(III) trifluoromethanesulfonate (In(OTf)3), a Lewis acid; and p-toluenesulfonic acid...

Detection of extremely small quantities of dangerous or hazardous substances is important in many areas, including national security, safety of public utilities and radiation prevention. Several analytical methods have been developed using structural, functional and electronic properties of nanomaterials. In particular, noble-metal quantum clusters (QCs), a family of nanomolecules exhibiting intense...

Capacitive desalination, in which salt ions are electrically removed from saltwater, has been researched for decades as a potentially cheaper alternative to energy-intensive reverse osmosis (RO) and distillation, but so far its application has been limited to waters with very low salt concentrations. A new method, which may change that, is being developed by researchers at Lawrence Livermore National...

An Australian team has developed a structure made of a metal organic framework (MOF) that captures and then releases CO2 using natural sunlight. The team includes researchers from: CSIRO Division of Materials Science and Engineering, (Clayton South, Victoria; www.csiro.au) the Dept. of Chemical Engineering, Monash University (www.monash.edu.au) and the School of Chemistry, University of Sydney...

Biosteel The worlds first artificial-silk fiber that is entirely made of recombinant spider-silk proteins has been produced by AMSilk GmbH (Planegg/Martinsreid, Germany; www.amsilk.com), a spin-off company of the Technical University of Munich. The fibers tensile strength is comparable to that of natural spider silk, and has thus been tradenamed Biosteel. Fiber prototypes are smooth to the touch...
