Physicists at Leipzig University have once again gained a deeper understanding of the mechanism behind superconductors. This brings the research group led by Professor Jürgen Haase one step closer to their goal of developing the foundations for a theory for superconductors that would allow current to flow without resistance and without energy loss. The researchers found that in superconducting copper-oxygen bonds, called cuprates, there must be a very specific charge distribution between the copper and the oxygen, even under pressure.

This confirmed their own findings from 2016, when Haase and his team developed an experimental method based on that can measure changes that are relevant to superconductivity in the structure of materials. They were the first team in the world to identify a measurable material parameter that predicts the maximum possible —a condition required to achieve superconductivity at . Now they have discovered that cuprates, which under pressure enhance superconductivity, follow the charge distribution predicted in 2016. The researchers have published their new findings in the journal PNAS.

“The fact that the transition temperature of cuprates can be enhanced under pressure has puzzled researchers for 30 years. But until now we didn’t know which mechanism was responsible for this,” Haase said. He and his colleagues at the Felix Bloch Institute for Solid State Physics have now come a great deal closer to understanding the actual mechanism in these materials.

It generates energy by forcing the stream to form a vortex.

Without employing any blades, the transportable hydraulic turbine SETUR from Vortex Hydrokinetics serves as a power source. The water source could be rivers, tidal streams, ocean currents, or even canals.

The portable equipment is lightweight as a result of the 3D-printed bladeless hydraulic turbine.

Scientists from UNSW Sydney have demonstrated a novel technique for creating tiny 3D materials that could eventually make fuel cells like hydrogen batteries cheaper and more sustainable.

In the study published in Science Advances, researchers from the School of Chemistry at UNSW Science show it’s possible to sequentially “grow” interconnected in 3D at the nanoscale which have unique chemical and to support energy conversion reactions.

In chemistry, hierarchical structures are configurations of units like molecules within an organization of other units that themselves may be ordered. Similar phenomena can be seen in the , like in flower petals and tree branches. But where these structures have extraordinary potential is at a level beyond the visibility of the human eye—at the nanoscale.

Photosynthesis is the greatest natural process converting sunlight into chemical energy on a massive scale and maintaining life on Earth. There are basically two successive stages of oxygenic photosynthesis.

Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.

I remember when this was a guitar.

The Flying-V, an experimental aircraft that promises significantly greater fuel efficiency over more conventional commercial jet designs, is moving towards a larger, more detailed version since the scaled, 10-foot model took flight in 2020 in Germany.

The 315-passenger jet flies like other commercial airliners its size, according to recent tests, but is 20 percent more fuel efficient. Plus, it just looks a lot cooler.

Australia has all the key critical minerals to power the next 100 years.

An Australian-based startup, Recharge Industries Pty, is planning to build a A$300 million (US$210 million) factory that can build lithium-ion batteries that do not have materials imported from China, Bloomberg.

Though Australia is the world’s largest supplier of lithium, a vital battery metal, it currently sends most of its battery raw materials to be processed into components in China.

With the explosive growth of technology, businesses are more vulnerable than ever to malicious cyber attacks. And as cybercriminals become more sophisticated, new methods of attack are popping up left and right.

To add fuel to the fire, the average cost of a data breach increased from $3.86 million to $4.24 million in 2021. That’s costly enough to put most SMBs into the red. Not to mention the reputational damage it can cause for your brand.

Piasecki Aircraft Corp. (PIAC) and edm aerotec have signed an agreement to develop the world’s first hydrogen-powered helicopter. Based in Pennsylvania, PIAC has a long history of designing experimental aircraft for civil and military applications.

CEO John Piasecki told a recent symposium at the Vertical Flight Society that his company would be performing the world’s first human-carrying flight tests aboard edm aerotec’s CoAX-2D helicopter. The hydrogen-powered CoAX-2D would use an 80-kW HyPoint high-temperature proton-exchange membrane (HTPEM) fuel cell, according to EVTOL.news.
