Polymorphism

Lithium batteries are in the news constantly. But lithium has plenty of other uses. It's a drug for bipolar disorder. It used to be put in soda for hangovers, and it saved the lives of the Apollo 13 astronauts. A little about lithium - a fascinating element.

MIT researchers fabricated 3D chips with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon between layers, leading to better and faster computation, for applications like more efficient AI hardware.

Scientists have analyzed images of the twin asteroids Didymos and Dimorphous taken by NASA's DART mission before it impacted the smaller space rock...

Promethium, one of the rarest and most mysterious elements in the periodic table, has finally given up some crucial chemical secrets

Alloying is a key process in creating new materials. By combining metals with desirable traits, scientists can produce alloys with suitable properties. For example, stainless steel, formed by combining iron with chromium, nickel, and other elements in smaller quantities is highly resistant to corrosion.

In a study led by Prof. Wei Xu (Interdisciplinary Materials Research Center, School of Materials Science and Engineering, Tongji University) and published in the journal National Science Review, a research team achieved the successful synthesis of a one-dimensional carbon chain on the Au(111) surface, with the longest chain containing approximately 120 carbon atoms, and the polyynic nature of the carbon chain was…

Vaterite is one of the three forms of calcium carbonate, along with calcite and aragonite. Nanosized vaterite is valuable for various applications, such as drug delivery, cosmetics, and bone defect filling, owing to its biocompatibility, high porosity, solubility, and large specific surface area.

Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique developed by a team of international scientists could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing…

Carbon nanotube (CNT) hybrid composites were formed by combining a CNT and silicone elastomer solution with Kevlar yarn, Kevlar fabric, and Kevlar veil materials. The integration of a CNT-silicone matrix with Kevlar yarn and fabric materials produced a composite with moderate electrical and thermal conductivity due to CNT fabric combined with the strength of Kevlar fabric or yarn. In the material synthesis, a…

The asteroid Dimorphous, three months after it was hit by a spacecraft

Material scientists at the University of Bayreuth in Germany have developed a glass that is more than twice as strong as Gorilla Glass. Corning's Gorilla Glass Victus...

The Hubble Space Telescope has snapped the results of smashing a spacecraft into the asteroid Dimorphous

Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia. To make space for the electrons a cavity forms in the liquid that the two electrons occupy.

A probe on Mercury used for the purpose of "surface-space-environment-geochemistry-and-ranging" abbreviated as the MESSENGER mission to Mercury, resulted in the discovery of geological structures known as hollows. Such landforms are quintessentially extraterrestrial with no close counterpart on the airless silicate bodies. Astrogeologists had used multispectral images and geochemical measurements via probes to show…

Asteroid 2023 FL2 is 35 meters, which is as much as almost 33 nine-banded armadillos lined up tail-to-snout. However, it won't hit us, and armadillos might even be more dangerous.
