Researchers have fabricated nanoscale color pixels that utilize three-dimensional space to improve and control the brightness of individual pixels with nanoscale lateral dimensions. Specifically, this novel method utilizes 3D printing of vertically freestanding nanostructures containing red, green, or blue light-emitting quantum dots embedded in polymer nanowires. The emission brightness of the pixels linearly increases with the height of the pixels due to the increase in the number of quantum dots due to the increased volume. The 3D geometry enables a 2-fold increase in brightness without causing significant changes in the lateral dimensions of the pixel.

A research team has developed a new technique to detect nano-sized imperfections in materials. They believe this discovery will lead to improvements in the optical detectors used in a wide range of technologies, from cell phones to cameras and fiber optics, as well as in solar cells.
Researchers are using new quantum chemistry computing procedures to categorize hypothetical electrocatalysts that are 'too slow' or 'too expensive', far more thoroughly and quickly than was considered possible a few years ago.
New research demonstrates atomic force microscopy imaging that gets around the challenges of exciting very small cantilevers at their high megahertz resonance frequencies. The approach accomadates wide frequency bandwiths, and is applicable for photosensitive materials in a wide range of liquids.
Scientists have developed the first micro-structured fibers with a viscous metal inside - a perfect example of what cross-disciplinary teamwork can achieve.
Researchers have developed a one-step lithography technique, also named direct nanocutting, for monolayer 2D materials using a thermomechanical indentation method.
What happens when you pull a DNA molecule? It behaves quite differently than we are used to from macroscopic objects. Scientists were now able to explain this.
