Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.che.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal ions in water. Up to now, existing test strips for metal ions have not been sensitive enough to detect ppb...

A single-step process for making phenol from benzene and carbon monoxide has been developed by Daicel Chemical Industries, Ltd. (Tokyo; edlinks.che.com/5826-543) with cooperation from Yasutaka Ishii, professor of applied chemistry at Kansai University (Osaka, Japan; edlinks.che.com/5826-544). Other attempts to make phenol directly, such as the reaction of benzene with hydrogen and oxygen over a...

Using lithium metal as the anode of secondary Li-ion batteries would double the energy density of conventional batteries, which use anodes based on carbon. However, Li-based anodes suffer from the problem of dendrite crystal formation during the charge and discharge cycles of the battery. The needlelike projections of these dendrite crystals can result in short...

Ultrasound Brewery Co. (Naruto, Japan; edlinks.che.com/5825-535) has developed a process that separates the water from dilute solutions of alcohol to achieve 99.5%, without using conventional evaporation or distillation. The company has tested the process in a pilot plant that produces 600–700 L/d of 99.5% ethanol from a 10–15% solution. The process, which combines irradiation with ultrasound...
