Highest energy density all-solid-state batteries now possible

Scientists have developed a new complex hydride lithium superionic conductor that could result in all-solid-state batteries with the highest energy density to date.

Optical 'tweezers' combine with X-rays to enable analysis of crystals in liquids

Scientists have developed a new technique that combines the power of microscale 'tractor beams' with high-powered X-rays, enabling them to see and manipulate crystals freely floating in solution.

Coffee-based colloids for direct solar absorption

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal energy mostly rely on the indirect absorption of sunlight, where the efficiency is generally limited as a result of major convective heat losses into the surrounding environment. A promising alternative is the direct absorption of sunlight, where a fluid can serve as both solar energy absorber and heat carrier.

How spin dances with dipole

The key physical property of multiferroic materials is the existence of a coupling between magnetism and polarization. The origin and manifestations of magnetoelectricity can be very different in the available multiferroic systems, with multiple possible mechanisms hidden behind the phenomena. In a new review, researchers have described the fundamental physics that causes magnetoelectricity from a theoretical viewpoint.

ATLAS experiment finds evidence of three massive vector boson productions

The ATLAS Experiment at CERN has just released evidence for the simultaneous production of three W or Z bosons in proton–proton collisions at the Large Hadron Collider (LHC). The W and Z bosons are the mediator particles of the weak force – one of the four known fundamental forces – which is responsible for the phenomenon of radioactivity as well as an essential ingredient to our Sun's thermonuclear process.

Research elucidates why protons are at the heart of atoms spin

A major new finding about the fundamental structure of all matter has just been published. The research stems from an analysis of data produced by an experiment in polarized proton-proton collisions.

Dynamic hydrogel used to make 'soft robot' components and LEGO-like building blocks

A new type of hydrogel material could soon make assembling complex microfluidic or soft robotic devices as simple as putting together a LEGO set.

Engineers demonstrate metamaterials that can solve equations

The field of metamaterials involves designing complicated, composite structures, some of which can manipulate electromagnetic waves in ways that are impossible in naturally occurring materials.

Golden ball in a golden cage

Researchers have synthesized a tiny structure from 32 gold atoms. This nanocluster has a core of 12 gold atoms surrounded by a shell of 20 additional gold atoms. The unusual stability of this cluster results from electronic interactions with amido and phosphine ligands bound to its surface.

In a new quantum simulator, light behaves like a magnet

Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions.
