    Published 2024
    “…To address these shortcomings, an injectable thermoresponsive gel‐based controlled release formulation is developed for the FDA‐approved Toll‐like‐receptor 7 (TLR7) agonist imiquimod (“Imigel”) that forms a tumor‐resident depot upon injection and contains a contrast agent for visualization under computed tomography (CT). The poly‐lactic‐<jats:italic>co</jats:italic>‐glycolic acid‐polyethylene glycol‐poly‐lactic‐<jats:italic>co</jats:italic>‐glycolic acid (PLGA‐PEG‐PLGA)‐based amphiphilic copolymer gel's underlying micellar nature enables high drug concentration and a logarithmic release profile that is additive with the neo‐antigen release from cryoablation, requiring only a single injection. …”

    Fouling and mitigation mechanisms during direct microfiltration and ultrafiltration of primary wastewater by Hube, Selina, Wang, Jingwei, Sim, Lee Nuang, Ólafsdóttir, Dagmar, Chong, Tzyy Haur, Wu, Bing

    Published 2022
    “…Several types of MF and UF membranes were examined by threshold flux determination, and two types of membranes (MF, 0.08 μm; UF, 100 kDa) were chosen for exploring membrane fouling mechanisms at different feed pressures via both fouling resistance analysis and optical coherence tomography (OCT) observation. The results revealed that both MF and UF displayed three-stage fouling behaviors, i.e., initial intermediate pore blocking followed by two-stage cake filtration. …”
