Topic: Recent Advances in Negative Thermal Expansion and Related Materials
Guest Editor
Special Topic Introduction
The vast majority of materials expand as the temperature increases, giving problems in many technological and engineering applications, such as fracture due to thermal stress or changes in properties of devices arising from their dimensional changes. For this reason, the development of materials with zero thermal expansion or, even better, with controlled thermal expansion, represents a challenge for materials design.
After the discovery in 1996 of a large negative thermal expansion (NTE) over a wide temperature range in zirconium tungstate, the interest in NTE has rapidly grown and the goal of controlling thermal expansion has become possible. NTE phenomenon is known to arise from a range of different mechanisms, such as low-energy vibrational modes in open-framework materials, magnetic and ferroelectric transitions, or charge transfer in the case of intermetallic compounds. To date, many NTE materials have been discovered and different methods are under investigation to achieve the control of thermal expansion, but there is still a long way to go.
This Special Issue aims to collect research papers and review articles of the 4th International Symposium on Negative Thermal Expansion and Related Materials (ISNTE-4), scheduled on July 5-7, 2023, in Padua, Italy, but is also open to external contributions. The Special Issue will focus on the recent advances in negative thermal expansion and related materials and will include (not limited to) the following subjects:
● NTE phenomena of phonon, electronic and magnetic origin;
● NTE materials (oxides, fluorides, metal organic frameworks, intermetallics, organic molecular materials, polymers, meta materials, etc.);
● different strategies for controlling the thermal expansion of materials and related applications;
● relationship between thermal expansion and thermo-responsive properties.
