Long-term stability is crucial for the future application of perovskite solar cells, a promising low-cost photovoltaic technology that has rapidly advanced in the recent years. Here, we designed a ...

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.

Despite massive strides in understanding HIV, there are still important gaps. A new study shows a method interferometry to capture extremely high-resolution visualizations of millions of molecules ...

Particles - molecules or ions - in a liquid and a gas are constantly moving randomly. Because of this movement, particles will spread themselves evenly throughout. Diffusion is one of the processes ...
