Real-time technique for studying ionic liquids at electrode interfaces

This electron microscope-based imaging technique could help scientists optimize the performance of ionic liquids for batteries and other energy storage devices.

Precision measurement on heavy ions contradicts theory of interaction between atomic nucleus and electron

For the first time, a team of researchers under the leadership of TU Darmstadt has succeeded in measuring the transition between energy levels of the lithium-like ions of bismuth with such precision that it has become possible to reassess underlying theories. This has led to a surprising result—the understanding of the interaction between an electron and an atomic nucleus that we have had until now might be erroneous.

Energy decay in graphene resonators

Researchers have observed a new way of energy dissipation in graphene nano-resonators, outlines a new report.

Preparations for a new season of physics at the Large Hadron Collider

Last week, the detectors of the Large Hadron Collider (LHC) witnessed their first collisions of 2017. These test collisions were not for physics research, instead they were produced as part of the process of restarting the LHC. But have patience, data taking for physics will start in another few days.

Swirling swarms of bacteria offer insights on turbulence

In the bacterial world, as in the larger one, beauty can be fleeting. When swimming together with just the right amount of vigor, masses of bacterial cells produce whirling, hypnotic patterns. Too much vigor, however, and they descend into chaotic turbulence.

New ATLAS precision measurements of the Higgs Boson in the 'golden channel'

The discovery of a Higgs boson in 2012 by the ATLAS and CMS experiments marked a milestone in the history of particle physics. It confirmed a long-standing prediction of the Standard Model, the theory that comprises our present understanding of elementary particles and their interactions.

Solving one of nature's great puzzles: What drives the accelerating expansion of the universe?

UBC physicists may have solved one of nature's great puzzles: what causes the accelerating expansion of our universe?

Quantum reservoir for microwaves

Researchers use a mechanical micrometer-size drum cooled close to the quantum ground state to amplify microwaves in a superconducting circuit.

Entropy landscape sheds light on quantum mystery

By precisely measuring the entropy of a supercooled cerium copper gold alloy with baffling electronic properties, physicists have provided further evidence about the common causes of high-temperature superconductivity and similar phenomena.

'Switchable' smart windows reduce energy consumption significantly

Smart windows that act as blinds in the summer and let all the sunlight through in the winter. That's the idea of the reflective windows that are able to reflect invisible infrared light but allow visible light through. In addition these windows can be 'switched on and off'. This new technology cuts the energy consumption for cooling and heating buildings by 12%.
