Their approach to designing the tiny light beam on a chip could also be used to create a variety of other nano flashlights with different beam characteristics for different applications. Think of a wide spotlight versus a beam of light focused on a single point.
An illustration shows bubbles of oxygen rising from the edges of six-sided, plate-like catalyst particles, 200 times smaller than a red blood cell, as they carries out a reaction called OER that splits water molecules and generates oxygen gas.
Bowel cancer survival rates could be improved if chemotherapy drugs were delivered via tiny nanoparticles to the diseased organs rather than oral treatment.
In a feat worthy of a laboratory conceived by J.K. Rowling, MIT researchers and colleagues have turned a "magic" material composed of atomically thin layers of carbon into three useful electronic devices.
