How Negative Thermal Expansion Alloys Are Reshaping Telescope Stability for Exoplanet Discovery
When the search for habitable exoplanets requires a 1,000 times more stable telescope than James Webb Space Telescope, even minimal material expansion down to a fraction of the width of an atom is the ...
The elastic modulus and coefficient of thermal expansion are fundamental properties of elastically stiff molecular materials and are assumed to be the same (symmetric) under both tension and ...
Most materials expand when heated. A few, such as water just above freezing, contract. Now, for the first time, physicists have found a material that switches from expanding to contracting in the ...
A research collaboration has created a pyrochlore magnet alloy with near-zero thermal expansion, outperforming Invar. This breakthrough, based on advanced computer simulations, stabilizes materials ...
In this interview, Venkat Nandivada Manager of Technical Sales at Master Bond Inc talks to AZoM about the tricky task of bonding two dissimilar substrates together. In your opinion, what is one of the ...
