The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions.

In a paper published in January 2024, my team of materials researchers demonstrated that a next-generation semiconductor material called metal-halide perovskite can actually recover and heal itself from radiation damage.

This high-mobility film shows unprecedented potential.

Physicists at the University of Stuttgart under the leadership of Prof. Sebastian Loth are developing quantum microscopy which enables them for the first time to record the movement of electrons at the atomic level with both extremely high spatial and temporal resolution. Their method has the potential to enable scientists to develop materials in a much more targeted way than before.

The researchers have published their findings in the journal Nature Physics (“Terahertz spectroscopy of collective charge density wave dynamics at the atomic scale”).

“With the method we developed, we can make things visible that no one has seen before,” says Prof. Sebastian Loth, Managing Director of the Institute for Functional Matter and Quantum Technologies (FMQ) at the University of Stuttgart. “This makes it possible to settle questions about the movement of electrons in solids that have been unanswered since the 1980s.” However, the findings of Loth’s group are also of very practical significance for the development of new materials.

A research team led by the Department of Energy’s Oak Ridge National Laboratory has bridged a knowledge gap in atomic-scale heat motion. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.

An environmentally friendly innovation, solid-state cooling could efficiently chill many things in daily life from food to vehicles to electronics — without traditional refrigerant liquids and gases or moving parts. The system would operate via a quiet, compact and lightweight system that allows precise temperature control.

Although the discovery of improved materials and the invention of higher-quality devices are already helping to promote the growth of the new cooling method, a deeper understanding of material enhancements is essential. The research team used a suite of neutron-scattering instruments to examine at the atomic scale a material that scientists consider to be an optimal candidate for use in solid-state cooling.

Superconductors are materials capable of conducting electricity without any resistance when they are cooled below a specific temperature known as the critical temperature. These materials are used in various applications such as power grids, maglev trains, and medical imaging equipment. High-temperature superconductors, which operate at higher critical temperatures than conventional superconductors, hold great promise for enhancing these technologies. Nonetheless, the underlying mechanisms of their superconductivity are not yet fully understood.

Copper oxides or cuprates, a class of high-temperature superconductors, exhibit superconductivity when electrons and holes (vacant spaces left behind by electrons) are introduced into their crystal structure through a process called doping. Interestingly, in the low-doped state, with less-than-optimal electrons required for superconductivity, a pseudogap ­­–a partial gap in the electronic structure– opens. This pseudogap is considered a potential factor in the origin of superconductivity in these materials.

NASA ’s OSIRIS-REx mission returned a sample from asteroid Bennu, revealing it contains key solar system materials and possible signs of a watery past. This discovery provides valuable insights into the early solar system’s conditions and the potential origins of life.

A deep dive into the sample of rocks and dust returned from near-Earth asteroid Bennu by NASA’s University of Arizona-led OSIRIS-REx mission has revealed some long-awaited surprises.

Bennu contains the original ingredients that formed our solar system, the OSIRIS-REx Sample Analysis Team found. The asteroid’s dust is rich in carbon and nitrogen, as well as organic compounds, all of which are essential components for life as we know it. The sample also contains magnesium sodium phosphate, which was as a surprise to the research team, because it wasn’t seen in the remote sensing data collected by the spacecraft at Bennu. Its presence in the sample hints that the asteroid could have splintered off from a long-gone, tiny, primitive ocean world.

A new superconducting compound offers a bridge to more practicals with a potentially attractive range of applications, according to new research. And the new material’s strange magnetic behavior recalls classics of decades ago—but this time in a material that’s already demonstrated its near-room-temperature bona fides.

Lanthanum hydrides—which combine atoms of the rare earth metal lanthanum with atoms of hydrogen—contain a range of superconducting materials of varying properties. One noteworthy material is lanthanum decahydride (LaH₁₀), which boasts the world’s highest accepted superconducting transition temperature, at −23 °C. (The catch is that to achieve this feat, lanthanum decahydride must be subjected to 200 billion pascals of pressure.)

Now a different lanthanum hydride (La₄H₂₃) has revealed similar if not quite equally impressive superconductivity stats. (Its transition temperature is −168 °C at 122 billion Pa.) However, the new lanthanum hydride also has revealingly peculiar magnetic properties that suggest an unexpected family resemblance to the superstar of the superconductivity world, cuprates.

AMD is reportedly planning to develop Glass Substrate chips as early as 2025 as Intel & Samsung eye mass production for post-2025.

Glass Substrates Are Expected To Be The Next Big Thing For The Tech Industry, Intel & Samsung Eye Towards Establishing Their Production While AMD Aims Chip Development As Early As 2025

Glass substrates are used in packaging solutions to replace organic materials. They have numerous benefits, such as higher packaging strength, which ensures more extended durability & reliability, and a higher interconnected density since glass is usually much thinner than organic material. This allows the integration of multiple transistors into a single pack. It is said to overcome flaws associated with traditional methods and open a new wave of innovation for computing chips employing glass substrates.
