In-situ rapid construction of aliphatic amine combined polyamide seawater reverse osmosis membrane for efficient boron removal
Published 2023“…The permeability coefficient of boron decreased from 4.8 to 0.9 L m−2 h−1, and the boron rejection increased from 80.7 to 90.5% under the modification conditions with the optimal type and concentration of amines, while displaying a NaCl rejection of 99.8% and an acceptable water permeability of 0.55 L m−2 h−1 bar−1. Meanwhile, the alteration of membrane chemical compositions and structure properties was kept to a minimum. …”

Engineering nano-nodular pattern on the substrate surface by tuning phase inversion to construct ultrapermselective ion-separation nanofiltration membrane
Published 2024“…The nano-nodular surface and thinner thickness exhibited a remarkable contribution to water permeability, which reached 38.3 L m−2h−1bar−1. The narrow pore size distribution made an outstanding Na2SO4 rejection of 99.1 % and Cl−/SO42− selectivity of 83 at 1000 mg/L of mixed salt solution. …”

Magical realism and representations of the cold war in Southeast Asia
Published 2016“…However, while there are acknowledgements by scholars that religious myths and pre-existing animistic beliefs continue to influence the way that the indigenous people understand their worlds, Southeast Asian authors (unlike many of their postcolonial peers), do not actively employ magical realism in their exploration of history and civil unrest in their writings, and when they do, are not employed to the same degree as postcolonial authors in other regions. …”

Ultramafic Alteration and the Cooling of Earth and Mars
Published 2024“…I show that the same high-surface-area clay minerals which bury organic carbon on Earth are prevalent enough on Mars to store the bulk of its initial 1-4 bar atmosphere as adsorbed methane. I postulate that this methane was formed abiotically during hydrothermal alteration of ultramafic rocks, a process which is observed in ultramafic systems on Earth. …”
