Precise control of copper's oxidation states in nanorod catalysts enables simultaneous nitrate wastewater purification and glycerol upcycling. Partially reduced copper oxide nanorods convert nitrate to ammonia at 96.8% efficiency, while fully oxidized versions transform glycerol into formate at 93% efficiency. The integrated system slashes energy consumption by 53.5%, offering a sustainable path for chemical production and environmental remediation.

Thermal stability and environmental sustainability are paramount to the practical deployment of perovskite solar cells (PSCs), which are designed to harness solar energy through high-efficiency and low-cost photovoltaic technology. Pseudo-halide thiocyanate anions (SCN⁻), employed as a crystallization modulator, have emerged as an ideal candidate for tailoring the formation of high-quality mixed-cation perovskite films, paving the way for a new era of efficient and high-quality PSCs.

The application of electromagnetic technology is becoming increasingly widespread, constantly expanding the scope of people's lives. However, the promotion and application of these electromagnetic products will also generate a large amount of electromagnetic waves (EMW), causing serious electromagnetic pollution. The design and preparation of high-performance EMW absorption materials is crucial, and composite materials with multiphase non-uniform interfaces are an ideal research object.

A breakthrough in battery technology has been made with the development of a polyvinylidene fluoride (PVDF)-Li₂CO₃ nanofiber network. This new material, developed through electrospinning, serves as a host for stable lithium metal plating and stripping, enabling a lithium metal anode for a battery. By integrating lithium carbonate into the nanofiber structure, researchers have created a more uniform lithium deposition, reducing dendrite formation and enhancing battery performance.

Light-sheet fluorescence microscopy (LSFM), with its innovative design of selective plane illumination and orthogonal detection optics, significantly reduces phototoxicity and photobleaching inherent in conventional microscopy, providing a revolutionary tool for long-term dynamic imaging of living specimens.

In a recent study published in Science China Earth Sciences, a team of researchers proposed using an orthogonal conditional nonlinear optimal perturbations (O-CNOPs) method to tackle the challenge of forecasting unusual tropical cyclone (TC) tracks. Their findings revealed that this method exhibits exceptional capability in generating ensemble members that accurately predict sharp TC turns. The O-CNOPs method holds potential as a transformative tool for addressing the forecasting challenge, offering a more precise and reliable solution for predicting TC behavior.

Forecasting unusual TC tracks has long been a persistent challenge in TC prediction, with limited progress made over the years. However, this study demonstrated that the O-CNOPs outperformed traditional methods [singular vectors (SVs) and bred vectors (BVs)] by providing more stable and reliable improvements in TC track forecasting skills. Notably, at lead times of one to five days, the O-CNOPs showed superior ability to generate ensemble members that accurately predict sharp TC turns. Thus, the study offers a new ensemble forecasting technology to enhance the accuracy of unusual TC track forecasts, with potential for becoming a valuable approach to address this forecasting challenge.

High-voltage lithium-ion batteries can deliver greater energy density but often suffer from severe electrolyte decomposition, transition-metal dissolution, and interfacial degradation—particularly under elevated temperatures. Researchers have now developed a kind of polyetherimide/polyimide (PEI/PI)-coated gradient-functional separator (PAP) that actively modulates interphasial solvation structures, forming a highly stable cathode–electrolyte interphase (CEI). This innovation enables lithium cobalt oxide (LCO) cells to operate at 4.6 V and 60 °C with markedly enhanced cycling stability, offering a promising pathway toward safer, high-energy-density batteries.
