Summary: Carbon dots/graphite carbon nitride (CDs/g-C3N4), a novel composite photocatalyst, has great potential for energy regeneration and environmental remediation due to its advantages of being metal-free, low cost, easily tunable, and excellent photocatalytic performance. This study reviews the development of synthetic strategies, photocatalytic enhancement mechanisms, and applications of CDs/g-C3N4 in various areas. The composite strategies of CDs and g-C3N4, as well as their advantages and disadvantages, are outlined. The photocatalytic enhancement mechanism is explained based on the changes in band structure, electronic properties, light absorption range, and interfacial charge transfer. The applications of CDs/g-C3N4 in hydrogen evolution, pollutant degradation, CO2 reduction, and bacterial disinfection are systematically reviewed.

Summary: Heterogeneous photocatalysis using advanced oxidation processes has a wide range of applications in water purification and environmental remediation. One promising material for this purpose is graphitic carbon nitride (g-C3N4), a metal-free polymer with excellent structural and physicochemical properties. However, challenges such as high recombination rate of electron-hole pairs, smaller specific surface area, and lower electrical conductivity limit the catalytic efficacy of g-C3N4. To overcome these challenges, magnetic nanocomposites (NCs) have been used to enhance the efficiency and reusability of the catalyst. This review summarizes the latest progress in the design and development of magnetic g-C3N4-based NCs and their applications in photocatalytic systems.

Summary: In this study, poly[(pyrene-1,3,6,8-yl)-phenyl-1,4-yl)-tri-phen] (PPyPP) loaded g-C3N4 nanocomposites were synthesized by one-step in situ thermal condensation method. The composites were characterized and compared to pure g-C3N4. The results showed that PPyPP/g-C3N4 composites exhibited significantly improved H-2 evolution rate (HER) and degradation of neutral red (NR) under visible light irradiation, due to the formation of a polymer heterojunction and effective charge transfer between PPyPP and g-C3N4.

Summary: Time-resolved EPR technique was used to study the formation of well-defined spin triplet excitons in carbon nitride. The mobility of the triplet excitons was revealed through the analysis of temperature-dependent TR-EPR signal. It was found that the energy of the spin triplet is approximately 0.2 eV higher than the conduction band edge, suggesting the inversion of singlet-triplet in carbon nitride materials. This study provides important insights into the response of carbon nitride to light and the nature of photoexcited states.

Summary: This study aims to examine whether adherence to ideal cardiovascular health (CVH) can mitigate the genetic risk of coronary artery disease (CAD) in non-European populations. The results showed that individuals with a favourable CVH profile demonstrated similar relative effects across Polygenic Risk Score (PRS) categories, reducing the CAD relative risk by a similar magnitude. Individuals with high PRS achieved the greatest benefit from favourable CVH, mitigating the risk to the average level of the population. Attaining favourable CVH should be encouraged for all individuals, especially those with high genetic susceptibility.

Summary: In this study, an intelligent optimization method integrating the BIM-DB and PSO-RF-NSGA-III methods was established for the energy saving design and optimization of near-zero-energy-consumption buildings (NZEBs). The method was applied to explore multiobjective optimization problems in four typical climate regions in China. The results showed that the PSO-RF algorithm efficiently predicted building energy consumption, carbon emissions, and thermal comfort. After optimization, the energy consumption levels in the four regions were reduced by 39.72%, 32.22%, 26.94%, and 35.37%, respectively, and other goals were also optimized. The optimized building design parameters met the standards for NZEBs, with varying influencing factors and measures across different regions.

Summary: We aim to enhance the ability of coupled phase oscillators to maintain synchronization under stochastic disturbances by proposing an optimization method. We model the disturbances as Gaussian noise and measure synchronization stability using mean first hitting time. The optimization method increases the mean first hitting time and identifies vulnerable edges in the system, increasing synchronization stability.

Summary: A giant enhancement of up to 34000 for out-of-plane (OP) exciton emission in indium selenide (InSe) is achieved via a designed plasmonic nanocavity consisting of a silver nanocube over a gold film. The large enhancement is attributed to the induced OP local electric field (Ez) within the nanocavity, which facilitates effective OP exciton-plasmon interaction. The nanoantenna effect resulting from the interaction also improves the directivity of spontaneous radiation, providing a potential avenue for designing on-chip photonic devices with an OP dipole orientation.

Summary: Exciton polariton condensation in an annular potential landscape can be controlled by an external field, resulting in rotational polariton flow with different orbit indexes. By using ring-shaped pumping in a planar perovskite microcavity, linear coupled counter-rotating polariton states and a vortex pairs-petal state have been demonstrated. The diameter of the pumping ring and the detuning energy can control the azimuthal indices and flowing velocity of the polaritons.
