This study investigates the co-pyrolysis behavior and product distribution of peanut straw and polyethylene film blends through thermogravimetric analysis and gas chromatography-mass spectrometry. Thermogravimetric analysis results revealed distinct pyrolysis temperature intervals: 247-356°C for peanut straw, 448-505°C for polyethylene film, and an extended range of 247-510°C for their mixtures. Synergistic effects, quantified through experimental-theoretical deviations, demonstrated enhanced mass conversion rates and accelerated pyrolysis kinetics in blended systems. As the mass ratio of peanut straw to polyethylene increases from 1:1 to 1:7, the bio-oil yield increased from 62.1% to 76.86%, accompanied by elevated alkane from 20.84% to 31.41% and olefin from 24.73% to 42.89%. HZSM-5 catalyst further optimized product profiles, achieving 77.08% bio-oil yield with enhanced hydrocarbon selectivity (alkanes: 35.69%; olefins: 46.16%) while suppressing oxygenates from 20.07% to 8.85%. These findings establish that co-pyrolysis with catalytic intervention effectively promotes hydrocarbon production and inhibits oxygenated compounds, providing strategic insights for agricultural plastic waste valorization.
Optical neural networks (ONNs) offer a pathway toward low-latency, energy-efficient artificial intelligence (AI); however, their scalability in terms of parameter count remains constrained. Addressing this challenge, a research team from The Chinese University of Hong Kong has developed a metasurface-based optical learning machine that integrates 41 million parameters, achieving performance comparable to state-of-the-art AI models. This approach experimentally enables highly scalable machine vision, thereby offering a practical pathway toward large-scale, high-performance optical AI computing.
A research team from the Shenyang Institute of Automation, Chinese Academy of Sciences, together with Peking University and collaborating institutions, proposes the Embodied Context Protocol (ECP). Centered on semantic interfaces and declarative workflows, ECP is an interface protocol for orchestrating embodied systems, connecting simulation platforms, data acquisition, model training, and inference execution into a reusable and auditable workflow.
Catalytically powered micro-/nanomotors have become a compelling alternative to conventional catalysts for active and efficient removal of environmental pollutants in water remediation. We developed a novel biocatalytic nanomotor system by encapsulating catalase and peroxidase enzymes into metal–organic frameworks (MOFs), demonstrating exceptional speed and facilitated motion-induced convection and mass transfer. Leveraging a synergistic structural etching and surface engineering strategy using tannic acid (TA), we create a tailored microenvironment of the MOF’s framework with charge-selective and nanoconfinement properties. Both experimental and simulation results indicate that microenvironment modulation of MOF matrix could act in synergy with the encapsulated enzymes and significantly improve efficiency and selectivity in removing charged pollutants. Surface engineering of TA selectively preconcentrates target contaminants by modulating the MOF shell's surface charge, while etching-induced voids facilitate rapid mass transfer to the enzyme active sites. Finally, we also validated the applicability of these nanomotors in the transformative removal of pollutants from the aqueous phase into polymeric products via an enzyme-mediated polymerization pathway. This biocatalytic nanomotor system provides a promising water remediation paradigm for reducing carbon emissions and recycling chemical energy from emerging contaminants.
Australian scientists have made a significant leap forward in energy storage technology by developing and testing the world’s first proof-of-concept quantum battery, new research reveals. Researchers say the technology could transform how we store and use energy in the future, paving the way for super-fast charging of devices.
