A compressible mixing layer facility CAD schematic. Credit: University of Illinois Department of Aerospace Engineering More Many of today’s scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life data. Providing validation data, using up-to-date methods,

Credit: CC0 Public Domain More Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes of behaviour and identify the important new ones. Their findings, published in the Proceedings of the National Academy of Sciences (PNAS),

The gold tip is moved across the surface of the topological insulator and experiences energy loss only at discrete, quantized energies. This is related to the image potential states that are formed over the conducting surface of the topological insulator. Credit: University of Basel, Departement of Physics More Topological insulators are innovative materials that conduct

Origami tiles represent crease motifs and can be put together like a jigsaw puzzle to create larger patterns. A completed puzzle is a code for a crease pattern that can be folded into multiple target shapes. Credit: source AMOLF More How can a single origami crease pattern be folded into two precisely defined target shapes?

Schematic of the 3D-integrated metasurfaces for full-color holography by vertically stacking a color-filter microarray with a hologram metasurface. (a) Exploded view of the 3D-integrated metasurfaces. The color-filter microarray can be specifically arranged to form a color microprint under white-light illumination (e.g., a mass-energy equation image), while the hologram metasurface can encode hologram information. When the

(a) Crystalline structure of the newly created superconductor. It has four sublayers in the conducting layer. This is in contrast to (b) and (c) which only have 1 and 2 layers respectively. The newly developed structure allows more customization to tune its superconducting properties. Credit: Tokyo Metropolitan University More Scientists from Tokyo Metropolitan University have
