    Enhancing proximal and remote sensing of soil organic carbon: A local modelling approach guided by spectral and spatial similarities by Qi Sun, Pu Shi

    Published 2025-05-01
    “…Increasing the weight assigned to geographical similarity during local learning enabled the selection of compositionally similar samples, which improved SOC prediction accuracy by 10.87 %, 2.50 %, and 7.21 % for RGB, DRS, and RSBS datasets compared to models relying on spectral similarity alone. …”

    Mechanical properties of natural gas wellbore structure under non-uniform load by Dongyin LI, Mingliang LI, Wen WANG, Yuxi HAO, Shen WANG, Hongbin LI

    Published 2025-03-01
    “…In areas where natural gas and coal resources overlap, the movement of overburden caused by high-intensity coal mining causes radial compression and deformation or even destruction of the natural gas well body structure within the protective coal pillar. The natural gas diffused from the damaged area can easily lead to fire, explosion or personnel poisoning accidents in coal mines. …”

    Recent advances in H2 purification and CO2 capture: Evolving from flat sheet to hollow fiber membranes by Jun Yi Teh, Wai Fen Yong

    Published 2024-12-01
    “…Additionally, H2/CO2 separation remains particularly challenging because H2, being diffusivity-selective, permeates more quickly through the membrane due to its smaller molecular size and higher kinetic energy, while CO2, being solubility-selective, has a high affinity for dissolving in most polymeric membranes. …”

    Preparation of Magnetic Photocatalyst Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>@Fe-TiO<sub>2</sub> and Photocatalytic Degradation Performance of Methyl Orange in Na<sub>2</sub>SO... by Li Sun, Zilong Li, Zhigang Yuan, Ying Liu, Shunqi Mei, Fanhe Meng, Xingyu Ouyang, Yi Xiong, Ke Zhang, Zhen Chen

    Published 2025-03-01
    “…In this study, Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>@TiO<sub>2</sub> (FS-FT (0 g)) photocatalysts, featuring a magnetic core–shell structure, and Fe-doped Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>@Fe-TiO<sub>2</sub> (FS-FT (x g)) photocatalysts, were fabricated via the sol–gel method. Structural and compositional analyses of the processed samples were systematically conducted through X-ray diffraction (XRD), transmission electron microscopy (TEM) with selected area electron diffraction (SAED), surface-sensitive X-ray photoelectron spectroscopy (XPS), and optical property assessment via UV-Vis diffuse reflectance spectroscopy (UV-DRS). …”
