EPFL engineers develop 3D-printed acoustic cavities for sound-powered robots
48+ min ago (401+ words) EPFL engineers have developed hollow acoustic cavities that can convert sound waves into directional thrust, a technique they say could enable small robots and ultralight aerial vehicles to move without conventional on-board actuators or electronics. The research, conducted by the…...
First Graphene builds one of the industry's broadest and most commercially advanced graphene platforms
2+ hour, 2+ min ago (856+ words) First Graphene (ASX:FGR, FRA:M11, OTCQB:FGPHF) is emerging as one of the most commercially advanced companies in the global graphene industry, through delivery of a viable and scalable product range, proven to enhance performance of materials across a wide…...
How Core-Shell Nanofibers Could Make Flexible Batteries More Heat-Resistant
3+ hour, 15+ min ago (310+ words) Microscopic analysis showed that the composite fibers had an outer diameter of 1.03 micrometers, a core diameter of 0.54 micrometers, and a shell thickness of 0.25 micrometers. Gel permeation chromatography confirmed that the mild, non-thermal fabrication process preserved polymer chain integrity without significant…...

Scientists Observe Quantum Heat Waves at Room Temperature For The First Time
9+ hour, 3+ min ago (254+ words) We've got another notable first in the field of physics to report: A specific type of quantum behavior in waves of heat has now been observed at room temperature, rather than at the ultra-low cryogenic temperatures that are usually required....
Crystalline polymer catalysts edge closer to efficient green hydrogen production
9+ hour, 25+ min ago (104+ words) Empa’s Proton highway project uses neutron crystallography and lattice dynamics to unlock faster proton transport in ceramic membranes, aiming to boos… Prof. Li’s team at PolyU has developed nanostructured cobalt catalysts to crack ammonia into hydrogen more efficiently, powering a…...
Scientists turn tiny “defects” into a 5.5x heat transfer boost
15+ hour, 24+ min ago (806+ words) Why Condensation Matters for Heat Transfer Condensation occurs when water vapor changes into liquid water. A familiar example is the layer of droplets that appears on the outside of a cold drink. In industry, condensation plays an important role in…...
