Scientists Discover how a Pinch of Salt can Improve Battery Performance

When the MOF is carbonised it transforms into a nano-diatom, much like a dragon egg turns into a fire-born dragon after fire treatment in Game of Thrones.

Researchers at Queen Mary University of London, University of Cambridge and Max Planck Institute for Solid State Research have discovered how a pinch of salt can be used to drastically improve the performance of batteries. They found that adding salt to the inside of a supermolecular sponge and then

NUS Engineers Invent Smart Microchip That Can Self-Start And Operate When Battery Runs Out

BATLESS, a smart microchip developed by a team of researchers led by Associate Professor Massimo Alioto (center) from National University of Singapore's Faculty of Engineering, can self-start and continue to operate even when the battery runs out of energy. This novel technology could enable smaller and cheaper Internet of Things (IoT) devices.

The Internet of Things (IoT), while still in its infancy, is shaping the future of many industries and will also impact our daily lives in significant ways. One of the key challenges of moving IoT devices from concept to reality is to have long-lasting operation under tightly constrained energy sources, thus

Chemists Develop MRI-Like Technique to Detect What Ails Batteries

A team of chemists has developed an MRI-based technique that can quickly diagnose what ails certain types of batteries -- from determining how much charge remains to detecting internal defects -- without opening them up. Above is an illustration of measurement setup showing the cell and the holder with the detection medium (water in this case), and (d) showing both inserted within the magnet bore of an NMR magnet.

A Novel Voltage Peak in the Metal Nanowire-Superconductor Hybrid Structure

Non-local transport measurements reveal a novel voltage peak at superconducting transition temperature in gold nanowire with superconducting W electrodes. The voltage peak appears when cooling the sample across Tc, while the peak turns into dip in the warming process. Upper inset, a scanning electron microscope image of Au nanowire contacted by two superconducting W compound electrodes in the middle and two normal Pt electrodes at the ends. Lower inset, configuration of electrodes. In fact, the detected peak is irrelevant to the current, and similar phenomena can be observed even in the absence of current.

Superconductivity, known as a quantum state with zero resistance and perfect diamagnetism, has attracted great attention in physical science. Due to the quantum size effect, low dimensional superconducting systems can exhibit novel behaviors different from bulk situation. Particularly, the investigations on
