One step closer to nanoparticle factories to produce medicine within the...
Could it be possible to one day deliver miniscule factories to the human body to produce medicine? In an article in the American Chemical Society’s journal Nano Letters, scientists described...
View ArticleMetamaterials + NanoCavities = Better, Smaller Lasers
The US Department of Energy’s Lawrence Berkeley National Laboratory and the University of California Berkeley have created the world’s smallest three-dimensional optical cavities. Most lasers use...
View ArticleProtein dynamics include scattering neutrons
Young collaborators and researchers at OakRidge National Laboratory prepare protein samples for neutron scattering on the Cold Neutron Chopper Spectrometer (CNCS). This goal is to understand protein...
View ArticleNanotherapeutics mimic blood platelets to dissolve clots
Researchers at Harvard University’s Wyss Institute have developed a new biomimetic strategy to deliver blood-clot-dissolving nanotherapeutics directly to obstructed blood vessels. This technique uses...
View ArticleElectricity from Friction
Friction is everywhere, and with the help of Georgia Tech researchers we are now a step closer to tapping into it for our electricity needs. While the principle of producing charge with friction is...
View ArticleRightie or leftie? Berkeley researchers change chirality
Handed, more often referred to as "chirality," is an important characteristic in the micro- and nano-scopic world. Many molecules we encounter in our everyday lives can come in two symmetric varieties...
View ArticleSilver's antibacterial properties: it's all in the ions
“We could not get consistent results,” he said. “It was very frustrating and really weird.” Zongming Xiu, a Rice postdoctoral researcher recently authored a paper describing his experiment. Xiu and his...
View ArticleSynthetic DNA vaccines
Vaccines are designed to mimic aspects of the microbe they hope the help the body build immunity to. Typically, this means dead or weakened versions of the microbe, or toxins and proteins that mimic...
View ArticleSmall hairy balls
Stable gold nanoparticles consist of a mere handful of gold atoms -- typically about one hundred. These "balls" of atoms are covered in organic molecule ligands (the "hair") which prevent the gold...
View ArticleAccidental, game-changing nanoparticle discovery
Penicillin, teflon, plastic, and now nanoparticles; all breakthrough discoveries stemming from scientific “failures.” University of Central Florida graduate student Soroush Shabahang was trying to...
View ArticleLogic gates from undoped nanowires
Overcoming the Schottky barrier, researchers have constructed the first ever logic gates from un-doped silicon nanowires. Silicon nanowires are one of the great hopes for the future of electronics,...
View ArticleGraphene properties depend on substrate
Graphene is pretty much as thin as it gets, being single-layered sheets of carbon molecules and all. As a result, graphene always needs to be supported by some other material. Silicon, for example....
View ArticleClean energy becomes a little cleaner
Cleanliness may be next to godliness, but it's also relevant for solar panel efficiency. "A dirty solar panel can reduce its power capabilities by up to 30 percent," says Seamus Curran, professor of...
View ArticlePrick-free diabetes testing
Nearly 300 million people worldwide live with diabetes, and regular testing is a crucial part of many of their lives. Purdue university researcher Jonathan Claussen and his team have created a device...
View ArticleSticking the non-sticky
The question seems almost philosophical: how do they get non-stick Teflon coating to stick to metal pans? At Kiel University in Germany, researchers are tackling a harder problem: how do you stick...
View ArticleNanocrystalline Algorithm Means More Alloys to Come
Trial and error is rarely fun, let’s be honest. Isolating effective metallic combinations for stable Nanocrystalline is likely no exception, though to be fair I have not been experimenting with alloys...
View ArticleRecycling silicon for batteries
Electronic waste is slowly becoming a large-scale problem for our technologically advanced society. Rice University researchers have developed a new way of recycling silicon into flexible components...
View ArticleSensing and preventing rust
The dominant method for evaluating rust characteristics of a metal in a certain environment is dead simple. Museums keen on the condition of their metal artworks, for example, will keep small metal...
View ArticleSupercomputer calculates isotopes allowed by laws of physics
A team at Oak Ridge National Laboratory used the Departments of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics. They applied density functional theory...
View ArticleWorld's smallest 3D nanoscale optical cavities hold promise for intense...
Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have developed the world’s smallest...
