Q&A: Plastic to metal, steel to aluminum—the future of welding and lightweight vehicles
Smarter 3D printing makes better parts faster
Software for powder bed fusion printers optimizes laser’s printing path.
Twisted vibrations enable quality control for chiral drugs and supplements
Terahertz light creates twisting vibrations in biomolecules such as proteins, confirming whether their compositions and structures are safe and effective.
Nanotechnology: Theory predicts new type of bond that assembles nanoparticle crystals
Turns out entropy binds nanoparticles a lot like electrons bind chemical crystals.
Nanostructures get complex with electron equivalents
Nanoparticles of two different sizes break away from symmetrical designs.
Mimicking a human fingertip’s sensitivity and sense of direction for robotic applications
With the help of 1.6 million GaN nanopillars per sensor, the University of Michigan team was able to provide human-level sensitivity with directionality on a compact, easily manufactured system
