The morphology of semiconductor blends greatly affects their performance in solar cells. Advances in scanning probe potentiometry are making it possible to image directly the build up of charge after a cell is illuminated.
The giant response of thermoelectric voltage to magnetic field in experiments on a model granular magnetic system is attributed to asymmetric spin-flip processes.
Mathematical modelling of materials' behaviour has become an indispensable tool that is urgently required for the development of the next generation of nuclear and fusion technology.
Choosing a porous solid for catalysis usually involves a trade-off between reactivity and mass-transport properties. Polycrystalline zeolite aggregates with adjustable mesoscopic pores make both available in one material.
