http://www.azonano.com The Lastest Nanotechnology and Nanoscience News from AZoNano - The A to Z of Nanotechnology en Copyright 2001-2008, AZoM.com Pty Ltd Imaging soft biological samples in liquid with Atomic Force Microscope (AFM) has long stood as a very challenging task. The XE-series AFM with crosstalk elimination (XE) has successfully solved the problems by operating in the "True Non-Contact Mode" instead of tapping mode. http://www.azonano.com/details.asp?ArticleID=2544 Dye-sensitized solar cells have received considerable attention as a cost-effective alternative to conventional solar cells. DSSCs operate on a process that is similar in many respects to photosynthesis, the process by which green plants generate chemical energy from sunlight. http://www.azonano.com/details.asp?ArticleID=2542 Nanotechnology offers new engineering tools that can help us address the design problems associated with building better implants. Rrecent technological advancements mean that we now have the ability to manipulate materials (and their surfaces) with nanometer scale accuracy. http://www.azonano.com/details.asp?ArticleID=2540 Sigma-Aldrich can supply Barium Titanate Nanopowder with a particle size of less than 100nm and purity of greater then 99%.
