Sensors with a transmitter built in

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…

This biodiesel process requires no pre- or post-treatment

Naomi Shibasaki-Kitagawa at Tohoku University (Sendai, Japan; www.che.tohoku.ac.jp/~rpel/) has developed a continuous reactor for making biodiesel fuel from low-quality waste, such as cooking oil. Her production process uses an expanded-bed reactor packed with an anion-exchange resin that has both catalytic…

Making 1,3-PDO from glycerin

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…

First application of sulfuric acid heap leach to vanadium

Following a positive feasibility study, American Vanadium Corp. (Vancouver, B.C.; www.americanvanadium.com) will construct the world’s first sulfuric acid heap-leach mining operation for vanadium at a specific geologic formation in central Nevada, known as Gibellini Hill. The project is currently in…

New GC based on resonating nanosensor

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…
