Russian scientists have conducted a theoretical study of the effects of defects in graphene on electron transfer at the graphene-solution interface. Their calculations show that defects can increase the charge transfer rate by an order of magnitude. Moreover, by varying the type of defect, it is possible to selectively catalyze the electron transfer to a certain class of reagents in solution.
Sauvignon Blanc, Semillon, or Chardonnay -- when you reach for your favourite white, it's the clean, clear sparkle that first catches your eye. Or does it? When white wines look cloudy it's a sign of protein instability, and a sure-fire way to turn customers away. Now, new research is ensuring white wines will always look their best as novel magnetic nanotechnology is proving to quickly and efficiently remove haze-forming proteins in white wine.
Scientists at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) in Germany have presented a non-contact method for detecting the state of charge and any defects in lithium-ion batteries.
Stanford engineers demonstrate a technology that could one day be scaled up to power a car moving down the road. In the nearer term, the system could soon make it practical to wirelessly recharge robots as they move around in warehouses and on factory floors -- eliminating downtime and enabling robots to work almost around the clock.
Freiburg researchers show how to control individual components of self-assembling molecular structures.
Quantum technology was once considered to be something very expensive and available only to the largest research centers. However, in our days it's widely used in many applications, and one of them is magnetic resonance imaging.
Thanks to its magnetic properties, the material -- zinc-doped manganese chromite -- can be used in a range of products, from gas sensors to data storage devices.
The Princeton University Department of Chemistry publishes research this week proving that an applied magnetic field will interact with the electronic structure of weakly magnetic, or diamagnetic, molecules to induce a magnetic-field effect that, to their knowledge, has never before been documented. With the experimental application of magnetic fields up to 25 Tesla, molecules with little intrinsic magnetism exhibit magneto-sensitive optical and photophysical properties.
Not only does a universal constant seem annoyingly inconstant at the outer fringes of the cosmos, it occurs in only one direction, which is downright weird.
Researchers have found a way to convert heat energy into electricity with a nontoxic material. The material is mostly iron which is extremely cheap given its relative abundance. A generator based on this material could power small devices such as remote sensors or wearable devices. The material can be thin so it could be shaped into various forms.
