The research groups of professor Yasuyuki Tsuji and assistant professor Tetsuaki Fujihara at Kyoto University (Japan; www.ehcc.kyoto-u.ac.jp) have developed a copper-catalyzed reaction for synthesizing carboxylic acids, such as acrylic acid, using carbon dioxide as a raw material. The reaction involves the hydrocarboxylation of alkynes with CO2 over a Cu catalyst. Two copper-based complexes showed high...

A group of scientists from Fudan University (Shanghai, China; www.fudan.ac.cn) China, has reported what it claims to be the first example of artificial single-molecular water channels that can transport water across lipid membranes. Transmembrane water transport — through water channel proteins called aquaporins — is of crucial importance in living organisms because it regulates the osmotic...

In the development process for coal-bed methane, water is produced from wells. It is high-salinity water, with total dissolved solids (TDS) generally at least 1,000 mg/L. The main concern with coal-bed methane co-produced water is the amount of Na+ and its influence on the environment. Therefore, the water must be treated before discharge and cost-effective technologies are needed to allow the use of the...

A recently launched, polymer-coated, fumed silica additive improves the performance of structural adhesives — those designed to bear loads. The new additive is capable of reducing the adhesive’s application viscosity, while simultaneously improving its ability to maintain a bead profile (sag resistance). Known as Cab-O-Sil Ultrabond, the additive was developed by Cabot Corp. (Boston, Mass....

There might be as many categories of catalysts as there are chemical processing applications. And, no matter what the specialty or application, most catalyst producers are in a constant state of research and development in order to meet the demands of their chemical processing customers, as well as to develop innovative catalysts for new applications and growing market areas. Recent efforts of some of the...

India holds large reserves of low-grade sulfide copper ore containing 0.3 wt.% copper, which cannot be processed through conventional routes since the cut-off grade for treatment in concentrators is about 0.45 wt.%. India is in short supply of copper and an appropriate technology for processing low-grade ores would contribute to India’s economy. Accordingly, a team from the Institute of Minerals...

Metals recovery Dinnissen Process Technology B.V. (Sevenum, The Netherlands; www.dinnissen.nl) has developed a purpose-built system to recover valuable metals — such as chrome and molybdenum — from highly viscous residual waste from the petrochemical industry. Such waste, which is often contaminated with wood, stone and iron particles, has been almost impossible to process, says the company...

For the first time, researchers from Riken (Saitama, Japan; www.riken.go.jp) have synthesized stable crystals (photo) of a so-called heavy ketone — a compound in which the carbon of the C=O bond is replaced by Si, Ge, Sn or Pb. These heavy ketones are highly reactive and prone to polymerization, which has made them difficult to synthesize and isolate to study...

A new process for removing oxides of nitrogen (NOx) from industrial foul-air and cool combustion exhaust uses ClO2 in a unique way to remove over 99% of both NO and NO2 with a single scrubbing stage. The reaction vessel is considerably smaller than those required by conventional wet-chemistry NOx removal processes, and according to the technology’s developer, Pacific Rim Design and Development (PRDD...
