Summary: In conventional photo-thermal-electric conversion systems, energy loss is caused by the physical contact interface between the photo-thermal conversion module and the thermoelectric conversion module. A new integrated support material has been developed to solve this problem, where the modules are connected without an apparent physical interface. This reduces heat loss and improves the water evaporation rate and open-circuit voltage of the system compared to non-integrated systems.

The study demonstrates a temperature-programmed synthetic approach to produce monolithic covellite nanodisks with controllable thickness and lateral diameters, expanding their plasmonic tunability across different infrared ranges. Additionally, the transformation of covellite nanodisks into multicrystalline digenite nanorings through a phase-transitioning process leads to modified plasmonic properties and energy shifts of the nanoparticles.

Summary: Due to their low operation voltage, high transconductance, and good aqueous compatibility, organic electrochemical transistors (OECTs) have found wide applications in sensing small redox-active molecules. However, selective detection of dopamine can be challenging. To improve the selectivity, a polypyrrole film was electrochemically deposited on the Pt gate electrode and then overoxidized, resulting in an OECT sensor with an overoxidized MIP (o-MIP/Pt) gate. This o-MIP/Pt gate showed similar detection limit as the bare Pt gate, but achieved a good selectivity towards dopamine compared to the interferent ascorbate.
