They simply call it Alloy 30, probably on account of the fact that is shows a -30 ppm/°C coefficient of thermal expansion at room temperature – in words we can all understand, a one-meter (3.3 ...

Even materials such as Invar and ZERODUR®, renowned for having low or even-zero coefficients of thermal expansion (CTE), have not been enough for this new generation of ultra-precision.

Researchers have discovered a negative thermal expansion material that shrinks by a record-breaking amount when heated, and which could help control materials' thermal expansion. The volume of the ...

In a groundbreaking development, NASA has announced a new alloy that could be the key to unlocking ultra-stable space telescopes needed to detect exoplanets and their potential for habitability. This ...

Takenaka notes that, "NTE materials will expand our capability of thermal-expansion control, opening a new paradigm of materials science and technology thermal-expansion-adjustable composites." ...

Nagoya University researchers discovered a negative thermal expansion material that shrinks by a record-breaking amount when heated, and which could help control materials' thermal expansion. The ...

Jun 28, 2024: New method developed for measuring thermal expansion in atomically thin materials (Nanowerk News) Advanced materials, including two-dimensional or atomically thin materials just a few ...

In a study published in the journal Physical Review Letters on Oct. 21, researchers described how they printed lightweight metamaterials with negative thermal expansion using 3D.

It's one of the basic facts of science: Heat something and it expands. But a team of scientists from LLNL have gone counterintuitive and invented a 3D-printed material that shrinks when heated.

“Zero-thermal-expansion materials are the dream, I would say,” said UChicago PME Research Assoc. Prof. Minghao Zhang, a co-corresponding author of the work.
