Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley.
The far-ranging potential applications of this technology include DOE’s hydrogen fuel cell-powered “Freedom CAR,” and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices.

Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production.
Fabrication technique could yield low-cost, scalable nanowire photonic and electronic circuits
Spearheaded by graduate student Mariano Zimmler and Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, both of Harvard’s School of Engineering and Applied Sciences (SEAS), and Prof. Carsten Ronning of the University of Jena, the findings will be published in Nano Letters. The researchers have filed for U.S. patents covering their invention.

Ceramic Bearings – Replacing Steel Bearings with Alumina Bearings in Circulator Pumps by Morgan Technical Ceramics
Background
With an annual production of approximately 10 million products a year and manufacturing operations in 12 countries Grundfos is one of the most recognised and respected pump manufacturers in the world. Dedicated to making its products as reliable and durable as possible, Grundfos works with partners, education institutions and suppliers to research and develop the best pump technology for its products. One of the longest relationships of this kind is with Morgan Advanced Ceramics, which supplies the manufacturer with bearings, shafts and washers for its circulator pumps.
Case Study – Ceramic Bearings for Circulator Pumps
Circulator pumps are used in central and district heating systems and domestic service systems. They need to be able to run quietly and consistently for long operational periods - often up to 5,000 hours a year. As part of its on-going work to improve its products, Grundfos realised that the traditional steel-shaft carbon bearings used in the pump were having a direct impact on the pump’s longevity and noise.
