T$_c$ and the elastocaloric effect of Sr$_2$ RuO$_4$ under 〈110〉 uniaxial stress: No indications of transition splitting [PDF]
There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus 66 at the critical temperature , observed in ultrasound measurements.

Achieving multiple effects of 3D-printed NiTi-based alloys via laser beam manipulation and their mutual collaboration for heat-driven elastocaloric cooling [PDF]
NiTi alloys can be made to demonstrate multiple effects including the shape memory effect (SME), superelastic effect (SE), and elastocaloric effect (eCE), by finely tailoring the Ni content. Notably, laser 3D printing technology has shown great potential

Evaluation of NiTi under low-amplitude cyclic loading by means of thermographic harmonic analysis [PDF]
Nitinol is a shape memory alloy exhibiting superelastic behaviour above a specific temperature. This property has allowed the design of a new breed of collapsible/expandable cardiovascular medical devices, which are generally characterised by high-risk ...

Research Update: The Mechanocaloric Potential of Spin Crossover Compounds
, 2016 We present a first evaluation of the potential for spin crossover (SCO) compounds to be considered as a new class of giant mechanocaloric effect materials. From literature data on the variation of the spin crossover temperature with pressure, we estimate
