New insights on wildfire smoke could improve climate change models
(Phys.org) —Where there's wildfire, there's smoke—a lot of it. And those vast, carbon-laden clouds released by burning biomass can play a significant role in climate change.
Deciphering butterflies' designer colors: Findings could inspire new hue-changing materials
Butterfly wings can do remarkable things with light, and humans are still trying to learn from them. Physicists have now uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly ...
New quantum dot technique combines best of optical and electron microscopy
It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology have developed a new microscopy technique that uses a process similar to how an old tube television ...
Cheap and quick HIV testing made possible with DVD scanners
Thanks to USB sticks and video streaming, DVD players are becoming all but obsolete. But their cheap optics may find a new life in a cost-effective and speedy technique for on-the-spot HIV testing and other ...
Video of the inside of a fly's eye: Scientists develop laser optics which support high-resolution 3D microscopy
Ultra-microscopes developed at the Vienna University of Technology can look into biological tissue, creating high-resolution 3-D images. A video has been created, showing a 3D-scan through a fly's head.
New freeform standards to support scanning CMMs
The National Physical Laboratory (NPL), the UK's National Measurement Institute, has developed a new range of three dimensional standards for verifying freeform coordinate measurement machines (CMMs). The standard allows ...
New imaging technique homes in on electrocatalysis of nanoparticles
(Phys.org)—By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena and everyday life. They may be used for the production ...
European researchers identify materials at the nanoscale
Spanish and German researchers have made a new instrumental development that solves a key materials science and nanotechnology question: how to chemically identify materials at the nanometre scale.
Superparamagnetic iron oxide nanoparticles could help track stem cells in the body
Researchers at the University of Liverpool have developed new methods to track stem cells and further understanding of what happens to them after they have been in the body for a significant period of time.
Microscopy reveals 'atomic antenna' behavior in graphene
Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices, according to a study led by researchers at the Department of Energy's Oak Ridge National Laboratory.
A breakthrough in superlens development: Cheap, simple lens to let us see a single virus
A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in ...
