Researchers developed a three-dimensional porous carbon-based current collector material and applied it to secondary batteries and supercapacitors to improve energy density and lifespan at the same time.
Scientists have developed a new method, called time-resolved momentum microscopy, for imaging individual quantum states in two-dimensional crystals of tungsten disulfide, which is crucial for understanding the interplay of these states and potentially unlocking their use in next-generation nanoscale solar cells or electronic sensors.
