Abstract
Energy conversion from the environment into electricity is the most direct and effective electricity source to sustainably power off-grid electronics, once the electricity requirement exceeds the capability of traditional centralized power supply systems. Normally photovoltaic cells have enabled distributed power generation during the day, but do not work at night. Thus, efficient electricity generation technologies for a sustainable all-day power supply with no necessity for energy storage remain a challenge. Herein, an innovative all-day power generation strategy is reported, which self-adaptively integrates the diurnal photothermal and nocturnal radiative cooling processes into the thermoelectric generator (TEG) via the spectrally dynamic modulated coating, to continuously harvest the energy from the hot sun and the cold universe for power generation. Synergistic with the optimized latent heat phase change material, the electricity generation performance of the TEG is dramatically enhanced, with a maximum power density exceeding 1000 mW m-2 during the daytime and up to 25 mW m-2 during the nighttime, corresponding to an improvement of 123.1% and 249.1%, compared with the conventional strategy. This work maximizes the utilization of ambient energy resources to provide an environmentally friendly and uninterrupted power generation strategy. This opens up new possibilities for sustained power generation both daytime and nighttime.

Abstract
The rapid development of the Internet of Things has triggered a huge demand for self-sustained technology that can provide a continuous electricity supply for low-power electronics. Here, a self-sustained power supply solution is demonstrated that can produce a 24 h continuous and unipolar electricity output based on thermoelectric devices by harvesting the environmental temperature difference, which is ingeniously established utilizing radiation cooling and selective photothermal conversion. The developed prototype system can stably maintain a large temperature difference of about 1.8 K for a full day despite the real-time changes in environmental temperature and solar radiation, thereby driving continuous electricity output using the built-in thermoelectric device. Specifically, the large output voltage of >102 mV and the power density of >4.4 mW m-2 could be achieved for a full day, which are outstanding among the 24 h self-sustained thermoelectric devices and far higher than the start-up values of the wireless temperature sensor and also the light-emitting diode, enabling the 24 h remote data transmission and lighting, respectively. This work highlights the application prospects of self-sustained thermoelectric devices for low-power electronics.

Abstract
The rising need for energy to actively heat and cool human-made structures is contributing to the growing energy crisis and intensifying global warming. Consequently, there's a pressing need for a sustainable approach to temperature management that minimizes energy consumption and carbon emissions. The substantial temperature differences between the Sun (approximately 5800 K), Earth (around 300 K), and outer space (about 3 K) offer a unique opportunity for passive thermal regulation on a global scale. Recent research indicates the possibility of addressing this issue through various low-carbon, passive technologies such as solar heating and radiative cooling. However, their practical application is often limited to certain seasons and climatic regions due to their static and single-function nature in managing temperature. In this context, we introduce a concept of phase-change metamaterials that provide passive, dynamic, and adjustable radiative thermal control, suitable for widespread engineering applications. Our designed metafilm comprises a Polydimethylsiloxane (PDMS) layer infused with vanadium dioxide (VO2) nanoparticles, backed by a layer of broadband-reflective silver (Ag). This metafilm exhibits a self-adjusting solar absorptance, shifting from 0.96 to 0.25 at a pivotal temperature while maintaining a nearly constant thermal emittance. We can finely tune the metafilm's optical characteristics by altering the VO2 nanoparticle concentration and PDMS layer thickness. To demonstrate its efficacy in solar thermal management and radiative cooling, we simulate its temperature behavior under various weather conditions.

Integration of plasmonic AgPd alloy nanoparticles with single-layer graphitic carbon nitride as Mott-Schottky junction toward photo-promoted H 2 evolution. Sci Rep 2022; 12:13583.

Abstract
Plasmonic AgPd alloy nanoparticles (AgPdNPs) decorated on single-layer carbon nitride (AgPdNPs/SLCN) for the designing of the Mott-Schottky junction were constructed with the ultrasonically assisted hydrothermal method and used toward photo evolution H2 from formic acid (FA) at near room temperature (30 °C). The Pd atom contains active sites that are synergistically boosted by the localized surface plasmon resonance (LSPR) effect of Ag atoms, leading to considerably enhanced photocatalytic properties. The photoactive AgPdNPs/SLCN obtained supreme catalytic activity to produce 50 mL of gas (H2 + CO2) with the initial turnover frequency of 224 h-1 under light irradiation. The catalyst showed stable catalytic performance during successive cycles.
