Personal drug delivery or nano-robotic systems could be a key concept for future medical applications. In this context, scientists around David Ng (Department of Professor Tanja Weil) of the Max Planck Institute for Polymer Research (MPI-P) have recently developed a technology to customize the shapes of polymers and polymeric nanoparticles using DNA. In both 2D and…

What happens in a solar cell when the lights go out depends heavily on the material being used. In conventional silicon solar cells, as found on rooftops or in pocket calculators, the answer is quite simple: the electrical current produced by the cell immediately goes to zero. It is different in so-called perovskite solar cells…

Organic light-emitting diodes (OLEDs) are used as light sources in high-quality smartphone displays and large-area high-end products such as OLED televisions. The main active component in an OLED is a light-emitting layer of an organic semiconductor, which converts electrical energy into visible light. In an OLED, the organic semiconducting layer is situated between two electrodes;…
