When compared to traditional refrigeration cycles, Peltier (thermoelectric) technology has many benefits, including no moving parts and no hazardous refrigerant chemicals. However, it has not yet been widely adopted into large-scale industrial processes (due to poor efficiency, inability to scale…
Scientists at Oregon State University (Corvallis; www.oregonstate.edu) have for the first time demonstrated the use of hydronium ions (H3O+) as charge carriers. The research opens another avenue of exploration for high-power, sustainable batteries for stationary power-storage applications. The research team,…
Efficient distillation Toyo Engineering Corp. (Toyo; Chiba, www.toyo-eng.co.jp) has completed construction for an energy-saving distillation system used in a project for Maruzen Petrochemical Co. (Tokyo, Japan; www.chemiway.co.jp). This system, tradenamed SuperHIDiC, has achieved an energy saving of over 50% compared…
Researchers from the Agency for Science, Technology and Research (A*STAR, Singapore; www.a-star.edu.sg) have developed low-cost, environmentally friendly iron-hydroxide coatings with unique fin-like shapes that absorb large amounts of pollutants, such as dyes, from drinking water, by means of a simple…
Today, ammonia continues to be manufactured by the Haber-Bosch process — an energy-intensive process that operates at high temperatures and pressures (above 400°C and 100 bars). For decades, researchers around the world have been looking for alternative routes to making…
United Technologies Research Center (UTRC; East Hartford, Conn.; www.utrc.utc.com) has been awarded a $2.7-million cooperative research agreement to further develop two technologies aimed at lowering the capital cost of flow batteries for electrical grid-energy storage. UTRC will lead the U.S.…
Scientists at Living Ink Technologies (Denver, Colo.; www.livinginktechnologies.com) have developed biodegradeable printing ink made from natural cyanobacteria and algae as a sustainable and non-toxic alternative to conventional petroleum-derived printing inks. Living Ink’s method involves using sunlight and carbon dioxide to…
A suitable catalyst for splitting water to make hydrogen must exhibit high H2-conversion efficiency, excellent durability, and must operate well under low voltage. For an efficient H2-evolution reaction, the catalyst must be able to trigger proton reduction with minimal overpotential…
The NiWest Nickel Laterite Project located at Murrin Murrin in the North Eastern Goldfields of Western Australia, has the potential to become a significant long-term, low-cost nickel producer through the development of heap leaching. The project is 100% owned by…
Achieving silicon of acceptable purity for solar-energy applications typically requires several purification steps. Now, a new process has been demonstrated that can produce high-purity Si from low-quality quartz in a single step. The PureVap technology from PyroGenesis Canada Inc. (Montreal,…
