Abstract: Heating and cooling combined constitute the world's largest form of end-use energy and the largest source of carbon emissions. It is therefore interesting to explore heat pumps based on caloric materials, which offer promising and environmentally friendly alternatives to gas combustion and vapor compression. The possibility of replacing these traditional methods of heating and cooling motivates the current research on caloric materials and devices. Here, we report the latest developments from the second biennial Calorics conference.
Highlights:
Discussion: How can caloric technologies be made more energy efficient to ensure they outperform traditional vapor-compression systems?What are the most significant barriers to scaling caloric materials and devices from lab-scale prototypes to commercial applications?Could integrating caloric technologies with renewable energy sources, such as solar or waste heat recovery, offer sustainable solutions for heating and cooling?

Electroactive bacteria (EAB) hold great promise for the development of electrochemical biosensors given their unique ability to transfer electrons extracellularly via specialized pathways, a process termed extracellular electron transfer (EET). Ongoing research aims to overcome current limitations and fully harness the potential of EABs for high-performance biosensing applications. Herein, we report the fabrication of an electrochemical microsensor based on biomineralized electroactive bacteria, specifically MR-1.

Inverted quantum dot light-emitting diodes (QLEDs) show great promise for next-generation displays due to their compatibility with integrated circuit architectures. However, their development has been hindered by inefficient exciton utilization and charge transport imbalance. Here, we present a strategy for regulating charge-exciton dynamics through the rational design of a multifunctional hole transport layer (HTL), incorporating polyethylenimine ethoxylated (PEIE) as a protective interlayer in fully-solution-processed inverted red QLEDs.

Bismuth ferrite (BiFeO) is a semiconductor with multiferroic properties, synthesized by the sol-gel method. While static high-pressure studies have advanced our understanding of the phase behavior of BiFeO, the effects of dynamic pressure acoustic shock waves remain unexplored. In this study, BiFeO was subjected to 100 shock pulses with 0.
