Scientists have developed a new, inexpensive material that has the potential to capture and convert solar energy - particularly from the bluer part of the spectrum - much more efficiently than ever before.
Electrical engineers have taken the first steps in a project to develop fast-blinking LED systems for underwater optical communications. They show that an artificial metamaterial can increase the light intensity and 'blink speed' of a fluorescent light-emitting dye molecule.
Winzige Röhren aus Kohlenstoff haben als effiziente Wandler von Licht zu Elektrizität ein größeres Potenzial als bisher geglaubt. Diese Eigenschaft, die Würzburger Forscher offengelegt haben, könnte für optische Sensoren und die Solartechnik dienlich sein.
If the chemical bonds that hold together the constituent atoms of a molecule could be tuned to become stronger or weaker, certain chemical properties of that molecule might be controlled to great advantage for applications in energy and catalysis. Researchers were able to accomplish this feat by using an applied voltage and electric current to tune the strength of chemical bonds in fullerene or 'buckyball' molecules.
Maya Mexican oil type has up to 30 parts per million of sulfur, labeling it as heavy oil, meaning, too pollutant for the environment when used as raw material for fuels. Looking to reduce the national hydrocarbon emissions, a team of scientists has created a catalyst for the oil industry.
The 2014 International Group IV Photonics Conference, sponsored by the IEEE Photonics Society, announces a Call for Papers seeking original research on the Electro Photonic Convergence on Silicon; Novel Materials and Structures; and Photonic Devices and Nanophotonics.
A new injectable material designed to deliver drug therapies and sensor technology to targeted areas within the human body is being developed by a biomedical engineer who says the system can lock its payload in place and control how it is released.
When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images - and those movements are virtually impossible to prevent. Now microscopy researchers at North Carolina State University have developed a new technique that accounts for that movement and eliminates the distortion from the finished product.
In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation of nanomaterials with unprecedented properties.
