Allowing the direct observation of biomolecules in dynamic action, high-speed AFM has opened a new avenue to dynamic structural biology. An enormous amount of successful applications within the last 15 years provide unique insights into essential biological processes at the nanoscale - visualizing, for example, how molecular motors execute their specific functions.
Mass adoption of perovskite solar cells will never be commercially viable unless the technology overcomes several key challenges, according to researchers.
Scientists have fabricated a new type of transistor from a germanium-tin alloy that has several advantages over conventional switching elements. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation.
