Super solar cells26 April 2007 Supramolecular dyes could boost efficiency in solar cells, say scientists from the UK. Saif Haque, from Imperial College, London, found that supramolecular dyes gave a 25% improvement in performance as compared to conventional, non-supramolecular dyes. Dye-sensitized solar cells typically consist of a dye-sensitised titania film and an organic semiconductor tha...
A team of Italian scientists has created a sunlight-powered cell that produces pure hydrogen from water. The team from the University of Milan and the University of Pavia are studying environmentally friendly ways to generate hydrogen, which could in future replace fossil fuels as a major energy source. The new cell has two compartments filled with water and separated by an electrode made of ...
图片说明:透射电子显微镜得到的图像表明,碳纳米管(深色区域)进入了细胞核。 (图片来源:Alexandra Porter) 英国科学家的一项最新研究,首次对碳纳米管进入人类细胞全过程进行了直接观测。研究人员发现,碳纳米管是否会造成细胞死亡取决于剂量和接触时间。这一成果为最终确定碳纳米管的毒性开辟了道路。相关论文发表于11月的《自然—纳米技术》上。 自从纳米技术兴起后,关于纳米材料毒性的争论就从未停止过。一些研究发现,纳...
