Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University report in Small Methods the 3D imaging of a suspended nanostructure. The technique used is an extension of atomic force microscopy and is a promising approach for visualizing various 3D biological systems.

Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.

Research at Kanazawa University as reported in Scientific Reports 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.
