Edible holograms could someday decorate foods

Holograms are everywhere, from driver's licenses to credit cards to product packaging. And now, edible holograms could someday enhance foods. Researchers reporting in ACS Nano have developed a laser-based method to print ...

High-resolution lithography for nanoporous thin films

Researchers at KU Leuven (Belgium) developed a high-resolution lithography process to pattern metal-organic framework (MOF) films. This work, published in Nature Materials, will speed up the integration of these materials ...

Plasma electrons can be used to produce metallic films

Computers, mobile phones and all other electronic devices contain thousands of transistors linked together by thin films of metal. Scientists at Linköping University, Sweden, have developed a method that can use the electrons ...
