Summary: The synergistic effect between metal ions and increased surface area allows for the creation of supercapacitor materials with high capacities. Transition metal selenide compounds are predicted to be ideal electrode materials for supercapacitors. However, poor conductivity and volume expansion are fundamental problems that need to be addressed. In this study, a cobalt-nickel selenide nitrogen-doped carbon (H-CoNiSe2/NC) hollow polyhedral composite structure was successfully synthesized using ZIF-67 as a precursor. The electrodes made from this composite showed high specific capacity, excellent cyclic stability, and ultrahigh energy density and power density in a hybrid supercapacitor configuration. This research provides a potential solution for developing high-capacity supercapacitor electrode materials for energy storage devices.

Summary: Designing bi-functional materials is crucial for sustainable energy storage and conversion. NiO electrodes show promise as supercapacitors and electrocatalysts, but their poor cycling stability hinders practical applications. To address this, we prepared core-shell structured NiO@CoSe2 samples through a multi-step hydrothermal method. These samples exhibited a specific capacitance of 1130 C g(-1) at a current density of 1 A g(-1). The assembled asymmetric device using the obtained product as the cathode delivered an energy density of 103.8 W h kg(-1) at 2700 W kg(-1). As an electrocatalyst for hydrogen evolution reactions, the NiO@CoSe2 sample showed an overpotential of 82.8 mV@10 mA cm(-2) and a Tafel slope of 72.14 mV dec(-1), respectively.

Summary: In this study, elastomeric micropyramid arrays with different heights were designed to redistribute strain and address the challenges of achieving high sensitivity and low hysteresis in piezoresistive tactile sensors. Single-walled carbon nanotubes were mixed into the micropyramids to compensate for conductivity loss and increase adhesion strength. The resulting sensor exhibited high sensitivity (1.28 x 106 kPa-1) and a broad detection range (4.51-54837.06 Pa) due to the synergistic effects of percolation, tunneling, and multistage strain distribution. Successful applications in health monitoring and human-machine interaction were demonstrated.

Summary: In recent years, there has been an increase in the proposal of passive radiative cooling materials, with a focus on silica (SiO2) due to its stability, non-toxicity, and availability. However, the bulk phonon-polariton band of SiO2 results in a reflection peak within the atmospheric transparency window, leading to a decrease in emissivity and posing a challenge for achieving sub-ambient passive radiative cooling. Therefore, the latest developments in this field aim to design engineered SiO2 photonic structures to enhance the cooling potential of SiO2 radiative coolers.
