Researchers have proposed a new thermo-elasto-plasticity constitutive model based on the interatomic potential and solid mechanics for metal crystals. Through this new model, the material behavior at different temperatures could be described accurately and conveniently.
Researchers have developed a method to improve the resolution of a conventional wide-field optical microscope. Scattered light usually reduces the resolution of conventional optical microscopes. The team however found a simple and efficient way to actively use scattered light to improve the resolution of images.
The U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) today announced more than $3.8 million in funding to support grants focused on using nanotechnology to find solutions to societal challenges such as food security, nutrition, food safety, and environmental protection.
This article describes investigations towards the development of innovative biomaterials able to direct the formation of complex tissues as well as their release from the biomaterial template with enormous implications in tissue engineering and regenerative medicine.
A microscopic tool, more than 1000 times thinner than the width of a single human hair, uses vibrations to simultaneously reveal the mass and the shape of a single molecule - a feat which has not been possible until now.
Building on their creation of the first-ever mechanical device that can measure the mass of individual molecules, one at a time, a team of scientists has created nanodevices that can also reveal their shape. Such information is crucial when trying to identify large protein molecules or complex assemblies of protein molecules.
They may deal in gold, atomic staples and electron volts rather than cement, support beams and kilowatt-hours, but chemists have drafted new nanoscale blueprints for low-energy structures capable of housing pharmaceuticals and oxygen atoms.
The study investigates the ability of amino-functionalized multi-walled carbon nanotubes to cross the Blood-Brain Barrier (BBB) by two ways: in vitro using a co-culture BBB model comprising primary porcine brain endothelial cells and primary rat astrocytes and, in vivo, following a systemic administration of radiolabelled f-MWNTs.
Ash trees in 22 eastern states of U.S.A. are being decimated by emerald ash borers (EABs), an Asian beetle that arrived in Michigan more than two decades ago. The pest has even spread westwards into Kansas and Colorado. Nothing seemed to be effective against EABs, until decoys designed to mimic female EABs were found in 2012 by a group of researchers to be successful in enticing male EABs for mating. Last year, the same researchers found the decoys could be used to electrocute and kill the seduced males.
