Barocaloric (BC) materials offer the potential for highly energy-efficient refrigeration by generating heat absorption through the effect of pressure on a solid-solid phase transition. However, very few of the known materials have the required phase transition in the temperature regions necessary for domestic refrigeration or air conditioning. We introduce organic ionic plastic crystals (OIPCs) as a new family of BC materials.

Thermal energy storage materials in combination with a Carnot battery could revolutionize the energy storage sector. However, a lack of stable, inexpensive and energy-dense thermal energy storage materials impedes the advancement of this technology.

- A study was conducted to analyze how often dermatologic surgeons face challenges in identifying the locations of skin cancer tumors before surgery.
- Out of over 17,000 cases, only 0.60% involved uncertain sites, with these cases more common in older, male patients who had biopsies done over a month prior.
- Surgeons commonly used various methods to confirm tumor locations, achieving success in identifying 82% of these uncertain sites, while some surgeries were delayed, especially for non-facial tumors.
