Cubic Crystal System

'Moonglass' made from the lunar surface might be particularly radiation-resistant.

A quantum leap in material science may soon make ultra-hard carbon a tangible reality.

In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.

There are a lot of myths about crystals − for example, that they are magical rocks with healing powers. An earth scientist explains some of their amazing...

The McDermitt Caldera on the Oregon-Nevada border may be the largest lithium deposit on Earth. So, how did it get there?

α-FAPbI3, a promising solar cell material with a cubic perovskite structure that is metastable at room temperature, can be stabilized by introducing a pseudo-halide ion like thiocyanate (SCN–) into its structure, as demonstrated by Tokyo Tech researchers in a new study. Their finding provides new insights into the stabilization of the α-phase via grain boundary and pseudo-halide engineering.

The invention of the printing press revolutionized duplication of the written word, giving the hands of tired scribes a break and making written material more accessible. A similar breakthrough has happened in reverse in the McKelvey School of Engineering at Washington University in St. Louis.

Using novel materials that have been widely studied as potential new solar photovoltaics, researchers at MIT have shown that nanoparticles of these materials can emit a stream of single, identical photons.

A group of researchers from Tohoku University has unveiled a new material that exhibits enormous magnetoresistance, paving the way for developments in non-volatile magnetoresistive memory (MRAM).

A 1-week schedule of 30 Gy delivered in five daily fractions was safe and effective in patients with early breast cancer. The study was published as a preprint and has not been peer reviewed.

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel. Not only is the metal exceptionally strong and ductile, its properties become enhanced as it gets colder. This runs counter to most other materials in existence.

New insight into the geochemistry of ancient environments can be gained through structural and chemical analyses of nanometer-scale features within mi…

The world is running out of helium. Helium is the only element cold enough to keep MRI machines cool enough to function. Without it, doctors lose a valuable ...

The preparation of quantum silicon nanowires, materials with potential application in high-performance nanodevices, is challenging. Here, the authors synthesize vertically aligned sub-5 nm silicon nanowires via a vapor phase silicon etching process; the resulting material features unusual lattice reduction and significant phonon and electronic confinement effects.

A new formation method for rare "lonsdaleite" diamonds may illuminate a better way to produce them on Earth

Lonsdaleite, a rare hexagonal form of diamond found in ureilite meteorites, formed shortly after an inner solar system dwarf planet collided with a large asteroid about 4.5 billion years ago.

Visualizing the amount of CO2 averted by nuclear reactors

The weapon, forged from an iron meteorite, may have come from beyond ancient Egypt's borders.

Just as an electrical switch regulates the flow of electric current, thermal switches can control the flow of heat. These switches serve as thermal control devices and are useful for thermal management applications. For example, they can be used in industries to reduce waste heat, resulting in cost and energy savings. These switches require materials whose thermal conductivity (κ) can be modulated to a large…

Both the mission and physics of ITER can be reduced to a single letter: Q. To understand the Q of ITER is to understand its most essential operating parameter [...]
