A new dimension for promoting electrocatalysis performance by noble metal aerogels
Noble metal aerogels (NMAs) are an emerging class of porous materials embracing nano-sized highly-active noble metals and porous structures, displaying unprecedented performance in diverse electrocatalytic processes. However, various impurities, particularly organic ligands, are often involved in ...
Molecular vibrations reduce the maximum achievable photovoltage in organic solar cells
Scientists at TU Dresden and Hasselt University in Belgium investigated the physical causes that limit the efficiency of novel solar cells based on organic molecular materials. Currently, the voltage of such cells is still too low - one reason for their still relatively low efficiencies. In ...
World record in research on π-electron structures
A team of international scientists led by of Francesca Moresco (Center for Advancing Electronics Dresden – cfaed at TU Dresden) and Diego Peña Gil (Center for Research in Biological Chemistry and Molecular Materials – CiQUS at University of Santiago de Compostela) has achieved a breakthrough in ...
A Dream Finally Comes True
Scientists at the Center for Advancing Electronics Dresden (cfaed) at TU Dresden have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic ...
Thanks to intensive research in the past three decades, organic light-emitting diodes (OLEDs) have been steadily conquering the electronics market - from OLED mobile phone displays to roll-out television screens, the list of applications is long. Current OLED research focuses in particular on ...
Organic semiconductors enable the fabrication of large-scale printed and mechanically flexible electronic applications, and have already successfully established themselves on the market for displays in the form of organic light-emitting diodes (OLEDs). In order to break into further market ...
Porosity is the key to high-performance materials for energy storage systems, environmental technologies or catalysts: The more porous a solid state material is, the more liquids and gases it is able to store. However, a multitude of pores destabilizes the material. In search of the stability ...
Organic light-emitting diodes (OLEDs) truly have matured enough to allow for first commercial products in form of small and large displays. In order to compete in further markets and even open new possibilities (automotive lighting, head-mounted-displays, micro displays, etc.), OLEDs need to see ...
Researchers reveal the nature of optical excitations
When light of specific frequency hits a semiconductor crystal, it is absorbed and produces a excitation, a state of higher energy. In solar cells, this energy can be converted into electricity and used. In two-dimensional crystals, which consist of only a few atomic layers, so called “excitons” ...
Physicists from Dresden and Würzburg have developed a novel method for optical microscopy. Using biological motors and single quantum dots, they acquire ultra-high-resolution images. The resolution of conventional optical microscopy is limited by the fundamental physical principle of diffraction ...
