    Enabling ultra-flexible inorganic thin-film-based thermoelectric devices by introducing nanoscale titanium layers by Ming Tan, Xiao-Lei Shi, Wei-Di Liu, Yong Jiang, Si-Qi Liu, Tianyi Cao, Wenyi Chen, Meng Li, Tong Lin, Yuan Deng, Shaomin Liu, Zhi-Gang Chen

    Published 2025-01-01
    “…The 10 nm Ti contact layer creates a strong bond between the substrate and the Cu electrode, while the 10 nm Ti barrier layer significantly reduces internal resistance and enhances the tightness between thermoelectric thin films and Cu electrodes. This enables both exceptional flexibility and an impressive power density of 108 μW cm−2 under a temperature difference of just 5 K, with a normalized power density exceeding 4 μW cm−2 K−2. …”

    Nano‐silicon fertiliser increases the yield and quality of cherry radish by Xinxin Xu, Yaozu Guo, Yi Hao, Zeyu Cai, Yini Cao, Wanzhen Fang, Bangyin Zhao, Christy L. Haynes, Jason C. White, Chuanxin Ma

    Published 2023-09-01
    “…The nutritional content of the edible tissue was significantly enhanced, with an increase of 23.7% in reducing sugar, 24.8% in total sugar, and 232.7% in proteins; in addition, a number of nutritional elements (Cu, Mn, Fe, Zn, K, Ca, and P) were increased. Si‐based NMs exposure positively altered the phytohormone network and decreased abscisic acid content, both of which promoted radish fresh weight. …”

    Development of sustained-release extemporaneous moxifloxacin loaded commercial soft hydrogel contact lenses by Duy Toan Pham, Pratthana Chomchalao, Kunasin Bunneramit, Phurichaya Kladcharoen, Rossukon Khotcharrat, Waree Tiyaboonchai

    Published 2025-02-01
    “…Isothermally, the moxifloxacin molecules were adsorbed onto the contact lenses surfaces via physical adsorptions by weak interactions of van der Waals forces, ionic bonding, and hydrophobic interactions. Furthermore, both the eye drops brands (Moximac and Zomoxin), the loading pH (6.7 and 6.0), and the loading time (24 h and 2 h) had no significant effects on the loading and release of moxifloxacin, indicating the system versatility. …”
