Converting sunlight into fuelPhotoelectrochemical cells are promising for the conversion of sunlight into fuel, for example, water into hydrogen, or CO2 into organic molecules. To realize this, a higher efficiency of the photocathode, often based on NiO, is needed. An important and unknown question is the role of water molecules adsorbed on the NiO surface. Kaijian Zhu performs research on the effects of this adsorption.Read more
Logical switching using one single moleculeLogic gates, the basic elements of our digital world, can now be built using one single molecule. An example is ‘XOR’, with two inputs. Is at least one of them ‘1’, than the output is ‘1’ as well, otherwise it is 0. These logic gates have a size less than two nanometer. They are based on ‘single electron transistors’, capable of assemblying and organising themselves on a surface. Molecular logic not only reduce the on-chip dimensions and lower energy consumption: it might well be that these circuits have similarities with the way our brain processes signals, says Prof Christian Nijhuis, who published his results in Advanced Materials.Read more
