  Artificial photosynthesis Scientists at Panasonic Corp.(Osaka, Japan; www.pana sonic.com) have developed an artificial photosynthesis system that utilizes sunlight to convert CO2 to organic materials (mainly formic acid) at what is said to be the highest efficiency yet achieved (0.2%). The efficiency level is comparable to that of plants. The keys to the Panasonic system are a nitride semiconductor, which is used as a photo-electrode for the reduction of CO2, and a metal catalyst to accelerate the reaction and increase selectivity. The research was presented at the International Conference on the Conversion and Storage of Solar Energy in July. The company hopes to use the development in a system to capture and converte waste CO2 from incinerators, power plants and other industrial processes.   Ion exchange The RecoPur system from Eco-Tec Inc. (Pickering, Ont.; www.eco-tec.com) improves the performance of the ion exchange process for treating produced water at oil drilling locations. The system features an ion-exchange resin with finer particles than conventional resins, and resin beds that are shorter, allowing higher flowrates in a more compact footprint. RecoPur is designed to efficiently remove calcium and magnesium…
