Scientists from Stanford and Illinois have created a heat-resistant thermal emitter that could significantly improve solar cell efficiency. The novel component is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity - a technology known as thermophotovoltaics.
The process can be carried out under any conditions, whatever the characteristics of the medium. This new click reaction can be used to connect two components (molecules, proteins, nanoparticles, etc.) in biological media as complex as human blood.
A team of MIT engineers has developed a way to detect blood clots using a simple urine test. The noninvasive diagnostic relies on nanoparticles that detect the presence of thrombin, a key blood-clotting factor.
Comparable to nanoscale Navy Seals, Cornell scientists have merged tiny gold and iron oxide particles to work as a team, then added antibody guides to steer the team through the bloodstream toward colorectal cancer cells. And in a nanosecond, the alloyed allies then kill the bad guys - cancer cells - with absorbed infrared heat.
RIKEN, the University of Tokyo and NIMS revealed that the size and helicity of a skyrmion, a magnetic structure consisting of electron spins arranged in a vortex shape, can be controlled by changing the concentration ratio of manganese and iron in Mn1-xFexGe.
The American Physical Society has awarded Rice University researchers Naomi Halas and Peter Nordlander the 2014 Frank Isakson Prize for Optical Effects in Solids in recognition of their groundbreaking research in nanophotonics.
Mapping of the chemical contents and their spatial distribution in a complex biological environment such as cells can be achieved by a new imaging modality: time-lens based hyperspectral stimulated Raman scattering.
Researchers are aiming to use ocean waves to produce energy by making use of contact electrification between a patterned plastic nanoarray and water. They have introduced an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy and as a chemical or temperature sensor.
