Cellulose-based nanocomposite aerogels were prepared by incorporation of aluminum hydroxide(AH) nanoparticles into cellulose gels via in-situ sol-gel synthesis and following supercritical CO_2 drying. The structure and properties of cellulose/AH nanocomposite aerogels were investigated by Fourier transform infrared spectroscopy, scanning electron microscopy,ultraviolet-visible spectrometry, N_2 adsorption, thermogravimetric analysis, and micro-scale combustion calorimetry. The results indicated that the AH nanoparticles were homogeneously distributed within matrix, and the presence of AH nanoparticles did not affect the homogeneous nanoporous structure and morphology of regenerated cellulose aerogels prepared from1-allyl-3-methylimidazolium chloride solution. The resultant nanocomposite aerogels exhibited good transparency and excellent mechanical properties. Moreover, the incorporation of AH was found to significantly decrease the flammability of cellulose aerogels. Therefore, this work provides a facile method to prepare transparent and flame retardant cellulose-based nanocomposite aerogels, which may have great potential in the application of building materials.

Near-perfect replication on amorphous alloys through active force modulation based on machine learning/neural network parameter prediction

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 181-191页

作者： Senkuan Meng Zheng Wang Ruisong Zhu Ruijie Liu Jiang Ma Lina Hu Weihua Wang Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials (Ministry of Education) School of Materials Science and Engineering Shandong University college of Mechatronics and Control engineering Shenzhen University Songshan Lake Materials Laboratory Institute of Physics Chinese Academy of Sciences

As a microforming technique, micro/nano-structural replication possesses advantages of high precision and efficiency. With the remarkable superplasticity in the supercooled liquid region, amorphous alloys or metallic glasses(MGs) are regarded as ideal materials for miniature fabrication. However, due to the intrinsic metastable nature of supercooled liquids, the design of imprinting processes for MGs poses a challenge. In the past, process parameters have largely relied on trial-and-error *** this work, a low-frequency active force modulation system is employed to apply a stable, precise, and real-time feedback stress field for imprinting of MG samples. Low-frequency vibrations can facilitate the filling of microstructures on the template surface by reducing the effective viscosity of the supercooled liquid. With the dataset composed of orthogonal experiments, a machine learning strategy based on back-propagation(BP) neural networks was utilized to construct a 3D parameter space for temperature, stress, and time, and to predict the corresponding filling ratio. Furthermore, the optimal combination of imprinting process parameters was identified, and its filling ratio was experimentally validated to reach as high as 0.94. The near-perfect replication of microstructures confirms the superiority of the active force modulation system and the data-driven strategy of machine learning-assisted parameter design. At the same time, this one-step microforming process provides a new approach to addressing the accuracy-cost trade-off dilemma in precision manufacturing.

活性氧是肿瘤化学动力学治疗具有突出效果的关键,但是肿瘤组织缺氧和高浓度谷胱甘肽的微环境阻碍了活性氧的产生.在此,我们构建了透明质酸修饰和过氧单硫酸盐负载的中空二氧化锰纳米颗粒（HA@HMn/PMS）,其不仅可以实现肿瘤微环境响应性药物释放,而且还可作为活性氧供体来增强肿瘤化学动力学疗效. HA@HMn/PMS在肿瘤部位富集后,消耗局部谷胱甘肽并将二氧化锰还原为二价锰离子,然后通过类芬顿反应和催化过氧单硫酸盐分别生成·OH和·SO4-自由基.·SO4-是一种罕见的自由基,具有优异的氧化能力和非氧依赖特性,它的产生和作用打破了传统活性氧的局限性,并且可以对肿瘤细胞造成严重的损伤.在异植瘤小鼠模型中,研究表明HA@HMn/PMS能够显著抑制小鼠肿瘤生长.本研究通过结合谷胱甘肽的消耗和多种自由基在肿瘤治疗中的协同作用,激发了化学动力学治疗在多功能纳米系统应用方向的潜力.
