Bionic wing flaps improve wind energy efficiency

Mar 22, 2022 (Nanowerk News) Wind energy relies on efficient wind turbine blades, which act as airfoils, structures akin to an airplane wing. Air flow control accessories similar to those found in aircraft improve the turbine blade's aerodynamic performance. In the Journal of Renewable and Sustainable Energy ("Using the combined...

Attosecond pulses: 100 times more

Mar 22, 2022 (Nanowerk News) Attosecond laser pulses in the extreme ultraviolet (XUV) are a unique tool enabling the observation and control of electron dynamics in atoms, molecules, and solids. Most attosecond laser sources operate at a pulse repetition rate of 1 kHz (1000 shots per second), which limits their...

Kirigami-style, self-folding circuit boards

Mar 22, 2022 (Nanowerk Spotlight) In an effort to develop simpler ways to fabricate complex 3D (nano)structures for use in electronics and other areas, researchers have repeatedly made use of kirigami at the nanoscale (see for instance our previous Nanowerk Spotlight on "kirigami-structured graphene-polymer hybrid nanocomposite for strain sensors"). Kirigami...

New experiment could confirm the fifth element

Mar 21, 2022 (Nanowerk News) An experiment which could confirm the fifth state of matter in the universe - and change physics as we know it - has been published in a new paper from the University of Portsmouth. Physicist Dr Melvin Vopson has already published research suggesting that information...

Leveraging AI to work with cells

Mar 21, 2022 (Nanowerk News) One of the ultimate goals of medical science is to develop personalized disease diagnostics and therapeutics. With a patient’s genetic information, doctors could tailor treatments to individuals, leading to safer and more effective care. Recent work from a team of Northwestern Engineering researchers has moved...
