    Published 2022-03-01
    “…In general, the interpretation of a heating structure as a bread oven necessitates an absence of nearly any other type of evidence of use, i.e. traces linked to the working of metals or glass or of hearth vitrification. In the same way, basing one’s interpretation of an oven as a bread oven based on the discovery of plant remains is a technical contradiction. …”

    Development of novel composite hollow fiber membranes for CO2 removal from biogas using membrane contactor by Xu, Yilin

    Published 2019
    “…Inspired by better gas selectivity along with tunable pore size and facile functionalization of metal-organic frameworks (MOFs), a highly efficient aminosilane-modified zeolitic imidazolate framework-8 (mZIF-8) based composite hollow fiber membrane with a dense skin layer was successfully fabricated for biogas upgrading in the GLMC process by dispersing mZIF-8 into dense polydimethylsiloxane (PDMS) matrix and depositing on a porous PVDF substrate. (3-aminopropyl)triethoxysilane was introduced to modify the ZIF-8 nanocrystals in order to cross-link with PDMS chains for further hydrophobicity enhancement. …”
