    Simultaneously Enhanced Permeability and Selectivity of Pebax-1074-Based Mixed-Matrix Membrane for CO<sub>2</sub> Separation by Rujing Hou, Junwei Xie, Yawei Gu, Lei Wang, Yichang Pan

    Published 2025-01-01
    “…Herein, branched polyethyleneimine (BPEI) containing a rich amino group was successfully grafted on the surface of the metal–organic framework (MOF) of AIFFIVE-1-Ni (KAUST-8) through coordination between N in BPEI and open metal sites in the MOF and with the resultant maintained BET surface area and pore volume. Both the strengthened CO<sub>2</sub> solubility coefficients coming from the additional CO<sub>2</sub> adsorption sites of amino groups in BPEI and the reinforced CO<sub>2</sub> diffusivity coefficients originating from the fast transport channels created by KAUST-8 led to the promising CO<sub>2</sub> separation performance for KAUST-8@BPEI/Pebax-1074 MMM. …”

    F. NIETZSCHE: KLASIKINIO MĄSTYMO METAFORINIS ARCHITEKTŪRIŠKUMAS IR JO SIMPTOMATIKA by Arūnas Mickevičius

    Published 2004-01-01
    “…Remiantis Nietzsche’s „valios siekti galios“ teorija, numatančia tik genealoginį, tipologinį ir simptomologinį pasaulio supratimą, siekiama parodyti, kad klasikinio mąstymo prigimtis yra ne racionali loginė, bet metaforiška. Todėl racionali klasikinio mąstymo raiška Nietzsche’s „galios“ filosofijoje atsiveria tik kaip niekada nepašalinamo pirmapradžio metaforiškumo liekana, kaip metaforiškumo suakmenėjimas ar neteisėta užmarštis ir kaip tik todėl racionalus klasikinis mąstymas Nietzsche‘s požiūriu ir negali apeliuoti į jokią universalią Tiesą, į jokį universalųjį pasaulio pažinimą, kylantį iš kokio nors vieno metafizinio pradžios taško. …”
