Scientists at Carbon Sciences Inc. (Santa Barbara, Calif.; www.carbonsciences.com) have successfully demonstrated a CO2-to-fuel process that proceeds under mild conditions using fluegas emissions as a carbon dioxide source and brackish water as a hydrogen source. The modular, three-step process is…
A hard biomaterial Researchers at the Fraunhofer Institute for Manufacturing Engineering and Applied Materials Research (IFAM; Bremen, Germany; www.ifam.fraunhofer.de) have developed a granulate form of a biomaterial that may replace titanium used as screws and other hardware in medical applications.…
Next year IHI Corp. (IHI; Tokyo, Japan; www.ihi.co.jp) plans to construct a demonstration plant in Indonesia that will gasify 50 ton/d of lignite (brown coal) into synthesis gas (syngas; predominantly hydrogen and carbon monoxide) using IHI’s twin-tower, bubbling fluidized-bed gasification process.…
Researchers at Texas A&M University (College Station, Tex.; www.tamu.edu) are poised to complete assembly of a pilot project that seeks to demonstrate the commercial viability of advanced vapor-compression desalination, an updated version of a decades-old distillation technology first developed for…
The process, developed by Masateru Nishioka at the Research Center for Compact Chemical Process, Institute of Advanced Science and Technology (AIST; Sendai; www.aist.go.jp) in collaboration with Shinko Kagaku (Koshigaya; www.shinkou-kagaku.co.jp), uses a microwave-assisted flow reactor developed by AIST and IDX…
Professor Tetsu Yonezawa at the Materials Science Div. of Hokkaido University (Sapporo; labs.eng.hokudai.ac.jp/labo/limsa/english/), in collaboration with Arios, Inc. (Akishima; www.arios.co.jp) and Suga (Hokuto, all Japan; www.suga.ne.jp), has developed a microwave-assisted device that can continuously generate a plasma under water. In…
Steam reforming of methane into hydrogen takes place in catalyst-packed alloy tubes that are heated in a furnace. Up to now, this energy-intensive reaction has used catalyst-impregnated ceramic pellets, which are poured into the tubes. However, these ceramic pellets do…
A research team at Princeton University (Princeton, N.J.; www.princeton.edu) led by Michael McAlpine and Yi Qi has devised a process for integrating nanoscale piezoelectric ribbons into flexible rubbers, enabling development of flexible, energy-harvesting materials. Efficient, flexible energy-conversion materials could be…
In January, the world’s first commercial plant to use the ITmk3 process began production of iron nuggets, which are used in steelmaking. The plant, constructed by Kobe Steel, Ltd. (Tokyo; www.kobelcom) and Steel Dynamics, Inc. (Fort Wayne, Ind.; www.steeldynamics.com) at…
A 1.5-mm-thick layer of a new filter material based on nanoscale alumina has shown the ability to filter greater than 99% of 0.03-µm latex spheres or 0.025-µm MS2 viruses with sustainable water velocities of around 1.5 cm/s at pressures of…
