A research team, led by Prof. Tao Zhang of Beijing University of Aeronautics and Astronautics, has landed major progresses in preparing metallic glass and associated mechanism studies, and rolled out the amorphous alloy materials desirable for ma- king stretching mechanisms for satellite solar cell arrays. In the lab, solar array’s 20cm long titanium metallic glass spiral rod is able to reach the length of 2m when stretched out. Researchers also mixed metallic glass powder with lubricants.

Jinwoo Cheon and colleagues from Yonsei Univer- sity, the Korea Basic Science Institution and the Yonsei University College of Medicine in Korea have worked out how to maximize the heat pro- duced by magnetic nanoparticles to extraordinary effect in the treatment of cancer. The researcher demonstrate a significant increase in the efficiency of magnetic thermal induction by nanoparticles. The optimized core-shell magnetic nanoparticles have specific loss power values that are an order of magnitude larger than conventional iron-oxide na- noparticles. They also perform an antitumour study in mice, and find that the therapeutic efficacy of these nanoparticles is superior to that of a common anticancer drug. © Nature Nanotechnology

UCLA researchers and their colleagues from China and Japan have shown that by incorporating gold nanoparticles into organic photovoltaics – taking advantage of the plasmonic effect, by which metal helps to enhance the absorption of sunlight – they can significantly improve the cells‘ power con- version. They demonstrate how they sandwiched a layer of gold nanoparticles between two light-absor- bing subcells in a tandem polymer solar cell in order
