Nanosuits help small creatures survive a vacuum
Research show mechanism behind wear at the atomic scale
(Phys.org)—Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on ...
New structures self-assemble in synchronized dance (w/ video)
With self-assembly guiding the steps and synchronization providing the rhythm, a new class of materials forms dynamic, moving structures in an intricate dance.
Designer materials: Entropy can lead to order, paving the route to nanostructures
(Phys.org) -- Researchers trying to herd tiny particles into useful ordered formations have found an unlikely ally: entropy, a tendency generally described as "disorder."
New 3-D photonic crystal has both electronic, optical properties
In an advance that could open new avenues for solar cells, lasers, metamaterials and more, researchers at the University of Illinois have demonstrated the first optoelectronically active 3-D photonic crystal.
Tiny generators turn waste heat into power
The second law of thermodynamics is a big hit with the beret-wearing college crowd because of its implicit existential crunch. The tendency of a closed systems to become increasingly disordered if no energy is added or removed ...
Deep-sea rocks point to early oxygen on Earth
Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists.
Safer nanoparticles spotlight tumors, deliver drugs
(PhysOrg.com) -- Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule ...
Beaming new light on life: From beetles to aircraft, nanoparticles aid microscope views
(PhysOrg.com) -- University of Utah physicists and chemists developed a new method that uses a mirror of tiny silver "nanoparticles" so microscopes can reveal the internal structure of nearly opaque biological ...
Nano 'beads on a string' could advance battery technology
Tiny beads of silicon, about ten thousand times thinner than a piece of paper, could someday make electric vehicles travel farther on a single charge or extend the life of your laptop's battery, say scientists ...
'Nano machine shop' shapes nanowires, ultrathin films
(Phys.org)—A new "nano machine shop" that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties.
Team creates new tech for complex micro structures for use in sensors, other apps
(Phys.org) -- University of Maryland Chemistry Professor John Fourkas and his research group have developed new materials and nanofabrication techniques for building miniaturized versions of components needed ...
Microscope probe-sharpening technique improves resolution, durability
(Phys.org) -- A simple new improvement to an essential microscope component could greatly improve imaging for researchers who study the very small, from cells to computer chips.
New printing method for nanostructures
(Phys.org) -- Swiss researchers have developed an economic, fast and reproducible method for printing tiny structures with a simple printing method. Now they are planning a spin-off.
