Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. In a new study, Edwin De Jong and co-workers at the interdisciplinary departments of Advanced Materials, Mechanical Engineering and Complex Molecular Systems developed an innovative "mechanowetting" technique to control droplet motion on changing surfaces based on the interfacial surface tension.

Ice lithography: Opportunities and challenges in 3-D nanofabrication
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.

Antibiotic resistance in spore-forming probiotic bacteria
New research has found that six probiotic Bacillus strains are resistant to several antibiotics. Genetic analysis of other Bacillus strains has shown genes that contribute to antibiotic resistance towards various types of drugs and methods in which they can still grow in their presence. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology.
