Engineers discover nanoscale balancing act that mirrors forces at work in living systems
(PhysOrg.com) -- A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size---an attribute that's important for many nanotech applications but hard to ...
Self-assembling structures open door to new class of materials
Researchers at the University of Illinois and Northwestern University have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres.
Bioengineers discover how particles self-assemble in flowing fluids
(PhysOrg.com) -- From atomic crystals to spiral galaxies, self-assembly is ubiquitous in nature. In biological processes, self-assembly at the molecular level is particularly prevalent.
New project aims for fusion ignition
Russia and Italy have entered into an agreement to build a new fusion reactor outside Moscow that could become the first such reactor to achieve ignition, the point where a fusion reaction becomes self-sustaining ...
Surprising discovery: X-rays drive formation of new crystals
detect broken bones, tumors and dental cavities, analyze atoms in diverse materials and screen luggage at airports -- but who knew they could cause crystals to form?
Theorists Close In on Improved Atomic Property Predictions
(PhysOrg.com) -- Scientists at the National Institute of Standards and Technology and Indiana University have determined the most accurate values ever for a fundamental property of the element lithium using a novel approach ...
