Nanotechnology and nanoscience are enabled by nanofabrication. Electron-beam lithography (EBL), which makes patterns down to a few nanometers, is one of the fundamental pillars of nanofabrication. In the past decade, significant progress has been made in electron-beam-based nanofabrication, such as the emerging ice lithography (IL) technology, in which ice thin-films are used as resists and patterned by a focused electron-beam. The entire process of IL nanofabrication is sustainable and streamlined because spin coating and chemical developing steps commonly required for EBL resists are made needless.

Perovskite solar cells tested for real-world performance—in the lab
It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

Imaging results, health data combine in AI model to predict breast cancer
Women know the drill: Breast cancer is too commonly a cancer diagnosis to be ignored, as early detection could make a difference. While false positives may cause an enormous amount of undue stress, false negatives have an impact on how early a cancer is detected and subsequently treated.
