New discovery makes fast-charging, better performing lithium-ion batteries possible
Posted by James Christian Smith in categories: electronics, transportation
Creating a lithium-ion battery that can charge in a matter of minutes but still operate at a high capacity is possible, according to research from Rensselaer Polytechnic Institute just published in Nature Communications. This development has the potential to improve battery performance for consumer electronics, solar grid storage, and electric vehicles.

Inside the lab using mind-changing psychology experiments to solve the Israel-Palestine conflict
Posted by Genevieve Klien in categories: electronics, neuroscience
To read a man’s mind, first you have to outline his skull.
Last November, I watched a psychologist use a digital pen to draw the circumference of a man’s head. The coordinates of his brain were quickly mapped, pinpointing the precise areas within his skull that process emotions. Behind him, a massive magnetic mind-reader—a neuroimaging device called a magnetoencephalography, or MEG—emerged from the wall, funneling into an oversized white helmet. It took two scientists to slowly maneuver the apparatus into position around his head.

A single superconducting artificial atom senses solid-state spins
Posted by Genevieve Klien in categories: electronics, particle physics
An electron spin resonance spectrometer using an artificial atom (a superconducting flux qubit) is realized, featuring both high sensitivity (400 spins/√Hz) and high spatial resolution (0.05 pL).

LHC beam pipe to be mined for monopoles
Posted by Quinn Sena in categories: electronics, particle physics
In February, the CMS and MoEDAL collaborations at CERN signed an agreement to hand over to MoEDAL a section of the LHC beam pipe that was located inside CMS between 2008 and 2013. The delicate object, 6 metres long and made of beryllium, will now be sliced and fed into a highly precise magnetic sensors in order to allow MoEDAL to look for magnetic monopoles: hypothetical particles with only a single magnetic pole – north or south – unlike north-south dipoles we are familiar with.
Paul Dirac posited the existence of magnetic monopoles in 1931, and, although never observed, they could be produced in collisions within the LHC. They would not travel very far after being produced, binding with the beryllium nuclei of the beam pipe and remaining there awaiting discovery.
The MoEDAL collaboration will cut the beam pipe at a special facility at the Centre for Particle Physics at the University of Alberta in Canada and ship the pieces back across the Atlantic to ETH Zurich in Switzerland to look for electromagnetic anomalies in them. Many theories attempting to unify all of the known forces into a single force (so-called “Grand Unified Theories”) require the existence of monopoles and finding them could open the door to all-new physics.

Physicists Have Finally Solved a Fundamental Mystery Concerning The Insides of Atoms
Posted by Quinn Sena in categories: electronics, particle physics
Something about atoms has never added up. Fundamental particles called quarks get kind of sluggish once they’re caught up in crowds of protons and neutrons – and quite frankly, they shouldn’t.
For decades, physicists have hunted for clues on the quark’s tendency to slow down in larger atoms, but have come up empty-handed. But now, a closer look at old data has finally revealed a clue to explain this strange phenomenon.
A massive team of physicists known as the CLAS Collaboration (after the CEBAF Large Acceptance Spectrometer) recently ran through data gathered from previous experiments at the Jefferson Lab’s Continuous Electron Beam Accelerator Facility.
