Researchers from Soochow University in China have developed a fast vapor-deposition strategy to fabricate twisted vertical heterostructures (TVHs) from two-dimensional organic crystals. By precisely controlling the deposition temperature through adjusting diffusion distance, the yield of vertical epitaxial structures is dramatically increased from below 20% to over 70%. The resulting TVHs exhibit a fixed 45° twist angle between crystal layers, enabling color-tunable interlayer coupling emission that ranges from blue to yellow-green. This work provides a practical approach for kinetic control of vertical heteroepitaxy and lays a material foundation for integrated photonics applications.

This study identified developmental stages and regulatory factors underlying stem quality of rapeseed (Brassica napus L.) under high-density planting. In two cultivars grown at low and high density, gibberellin (GA)-triggered early stem elongation was found to be associated with delayed secondary cell wall deposition and reduced stem mechanical strength under high density. Foliar application of the GA biosynthesis inhibitor uniconazole at the 10–11 leaf stage delayed GA activation and slowed stem elongation, increasing stem mechanical strength and yield.

The WHO Global Action Plan for Poliovirus Containment, 4th edition (GAPIV) describes the necessary conditions for the containment of poliovirus material in poliovirus-essential facilities (PEFs). The method used for validation of chemical products for poliovirus decontamination in this study was based on processes outlined in European Standard EN14476, as recommended by the WHO GAPIV guidelines. The disinfectants 5 % Microchem Plus and 1 % Virkon®S were evaluated for efficacy against high titre poliovirus in solutions with and without high organic load using an endpoint dilution assay. A poliovirus Sabin 1 strain was used as the reference virus with the titre 8.33 log10 CCID50 (50 % cell culture infectious dose) in 0.1 ml. Microchem Plus only partially inactivated poliovirus and cannot be relied upon as the sole decontaminant. In contrast, Virkon®S performed well for both high titre poliovirus in solutions with and without high organic load, achieving >4 log10 titre reduction for both, making Virkon®S a suitable disinfectant for poliovirus.

Using seawater for large-scale electrolysis offers a highly promising route for sustainable energy systems, but aggressive chloride ions typically cause rapid degradation of conventional anodic catalysts. Researchers from Hainan University and Swinburne University of Technology have developed a self-stabilizing boron-doped high-entropy selenide for the anodic oxygen evolution reaction. By coupling dynamic valence oscillations for active-site protection with a robust selenate layer to repel chloride, this catalyst achieves over 1000 hours of continuous operation at industrial-level currents in a harsh seawater environment.

Nanoporous carbon materials have attracted significant interest for applications in lightweight structural materials, microdevices, and bio-integrated systems due to their low density, chemical stability, electrical conductivity, and tunable mechanical properties. However, existing fabrication approaches often struggle to simultaneously achieve precise patterning, controllable porosity, and desirable mechanical performance. A research team led by Professor Min Qiu at Westlake University has developed a new fabrication strategy, termed Mix-ice lithography (Mix-IL), that enables direct construction of nanoporous carbon structures with tunable pore architectures and complex geometries. The study has been published in Science Bulletin.

Researchers from Shanxi University and Nanjing University have demonstrated on-chip two-mode squeezed light at audio frequency as low as 60 Hz, bringing integrated quantum noise reduction into the audio-frequency band. A weak, orthogonally polarized electro-optic reference comb stabilizes the homodyne measurement phase without placing a bright locking tone at the quantum frequencies. The experiment observed approximately 1 dB of squeezing from 60 Hz to 5 kHz, reconstructed the two-mode covariance matrix, and verified entanglement using the positive partial transposition criterion.

This study develops a novel “Panning for Gold” framework that integrates Koopman analysis with clustering algorithms to identify representative water quality dynamic data for wastewater treatment plants (WWTPs). Using a full-scale Anaerobic-Anoxic-Oxic process in southern China as a case study, the research demonstrates that machine learning models can maintain predictive accuracy with 43.59% less training data, establishing a low-data-requirement paradigm for efficient water system management.
