Cicada wings could inspire next-gen surface technologies

Cicada wings could inspire next-gen surface technologies
Researchers are looking to insects - specifically cicadas - for insight into the design of artificial surfaces with de-icing, self-cleaning and anti-fogging abilities. Their wings allow cicadas to fly, of course, but they also are good at repelling water - a condition that humans can appreciate, too. "Our work with cicadas is letting us explore a field called bioinspiration," said Nenad Miljkovic, a University of Illinois mechanical science and engineering professor who co-led a new study of cicada wings.

Dynamic templates critical to printable electronics

Dynamic templates critical to printable electronics
Researchers at the University of Illinois have developed bio-inspired dynamic templates used to manufacture organic semiconductor materials that produce printable electronics. It uses a process similar to biomineralisation—the way that bones and teeth form. This technique is also eco-friendly compared with how conventional electronics are made, which gives the researchers the chance to return the favor to nature.

GaN-on-Silicon optimises high electron mobility transistors

GaN-on-Silicon optimises high electron mobility transistors
A team of researchers at the University of Illinois at Urbana-Champaign has advanced gallium nitride (GaN)-on-silicon transistor technology by optimising the composition of the semiconductor layers that make up the device. Working with industry partners Veeco and IBM, the team created the high electron mobility transistor (HEMT) structure on a 200 mm silicon substrate with a process that will scale to larger industry-standard wafer sizes.

Demonstrating tunable wetting and adhesion of graphene

Demonstrating tunable wetting and adhesion of graphene
Researchers from the University of Illinois at Urbana-Champaign have demonstrated doping-induced tunable wetting and adhesion of graphene, revealing unique opportunities for advanced coating materials and transducers. "Our study suggests for the first time that the doping-induced modulation of the charge carrier density in graphene influences its wettability and adhesion," explained SungWoo Nam, an assistant professor in the Department of Mechanical Science and Engineering at Illinois.
