On December 7th, both professor Zhang of advanced materials department and professor Wang Qiangbin of nano biomedical research department invited professor Alexander Eychmüller of Tu Dresden University of Germany visited the Institute. Alexander was employed as a visiting professor of the Institute. During the meeting, Alexander Eychmüller gave an academic report entitled "nanoparticles from Dresden and what they are good for".
The theme of the report involves ordered superstructure of semiconductor nanoparticles, nanocrystals embedded in Macrocrystals of different components, gel and aerogels with different compositions of nanocrystals. Ordered superstructures (mesoscopic crystals) are assembled from IV-VI semiconductor nanocrystals / microcrystals. When the nanocrystals are embedded into the macro crystal of salt, they show remarkable light stability and enhanced emission quantum yield, which is expected to be applied in color change. Recently, disordered superstructures derived from nanocrystals, such as gelatin and aerogels prepared from different components of nanoparticles, have proved that nanomaterials can be organically integrated with macroscopical materials, making nanomaterials as easy to manipulate and process as macroscopical materials, while retaining some nano scale characteristics. These materials have very low density and open porous network structure, which makes them show great potential in many applications.
Alexander Eychmüller is the director of the Department of physical chemistry and electrochemistry of Dresden University of technology, Germany. He is the consultant and member of the senate of the basic science review committee of Dresden University of technology. He mainly focuses on the synthesis, structure and properties of submicron to atomic size semiconductor materials, and has made many remarkable achievements in the fields of photoelectric conversion, electrochemical sensing and biotechnology . More than 250 papers have been published in nature medicine, Nature Nanotechnology and other international high-level journals, cited more than 11000 times, invited to give reports by more than 120 international conferences, and his H factor is 54.
