Breakthrough in 3D magnetic nanostructures could transform modern-day computing
Scientists have taken a step towards the creation of powerful devices that harness magnetic charge by creating the first ever three-dimensional replica of a material known as a 'spin-ice'. Spin ice materials are extremely unusual as they possess so-called defects which behave as the single pole of a magnet.

It takes some heat to form ice
It takes some heat to form ice
Researchers from TU Graz in Austria and the Universities of Cambridge and Surrey succeeded to track down the first step in ice formation at a surface, revealing that additional energy is needed for water before ice can start to form. Picture material for download at the end of the message Water freezes and turns to ice when brought in contact with a cold surface - a well-known fact.

Zero-carbon energy from sea water a step closer
Researchers at McGill University have demonstrated a technique that could enable the production of robust, high-performance membranes to harness an abundant source of renewable energy. Blue energy, also known as osmotic energy, capitalizes on the energy naturally released when two solutions of different salinities mix - conditions that occur in countless locations around the world where fresh and salt water meet.

Study of promising photovoltaic material leads to discovery of a new state of matter
Researchers at McGill University have gained new insight into the workings of perovskites, a semiconductor material that shows great promise for making high-efficiency, low-cost solar cells and a range of other optical and electronic devices. Perovskites have drawn attention over the past decade because of their ability to act as semiconductors even when there are defects in the material's crystal structure.

Harnessing the hum of fluorescent lights for more efficient computing
The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity. A team led by University of Michigan researchers has developed a material that's at least twice as "magnetostrictive” and far less costly than other materials in its class.

Parallel universes cross in Flatland
Parallel universes cross in Flatland
Physicists at the University of Bath observe modified energy landscapes at the intersection of 2D materials. Last updated on Tuesday 11 May 2021 In 1884, Edwin Abbott wrote the novel Flatland: A Romance in Many Dimensions as a satire of Victorian hierarchy. He imagined a world that existed only in two dimensions, where the beings are 2D geometric figures.

A material-keyboard made of graphene
A material-keyboard made of graphene
Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.

Africa's oldest human burial site uncovered
Africa’s oldest human burial site uncovered
The discovery of the earliest human burial site yet found in Africa, by an international team including several CNRS researchers 1 , has just been announced in the journal Nature . At Panga ya Saidi, in Kenya, north of Mombasa, the body of a three-year-old, dubbed Mtoto (Swahili for 'child') by the researchers, was deposited and buried in an excavated pit approximately 78,000 years ago.

Ion Beams Mean a Quantum Leap for Color-Center Qubits
Ion Beams Mean a Quantum Leap for Color-Center Qubits
A new way to form self-aligned 'color centers' promises scalability to over 10,000 qubits for applications in quantum sensing and quantum computing. -By Joe Chew Achieving the immense promise of quantum computing requires new developments at every level, including the computing hardware itself. A Lawrence Berkeley National Laboratory (Berkeley Lab)-led international team of researchers has discovered a way to use ion beams to create long strings of "color center" qubits in diamond.

Advances for the application of nanofluids to energy storage systems
Advances for the application of nanofluids to energy storage systems
Energy storage systems are key technologies for achieving the transition to renewable energies, which can become more viable if the energy efficiency of the former improves. At present, more than 70% of concentrated solar power systems have integrated thermal energy storage (TES). Such power plants reached an installed capacity of 4.5 GW at the end of 2019.

Inspired by nature, the research to develop a new load-bearing material
Engineers have developed a material that mimics human cartilage - the body's shock absorbing and lubrication system, and it could herald the development of a new generation of lightweight bearings. Cartilage is a soft fibrous tissue found around joints which provides protection from the compressive loading generated by walking, running or lifting.
