Summary: Viscous oil separation and its highly efficient recovery is a challenging task in oil/water separation. A nondispersive solvent extraction strategy using a polydopamine modified PVDF Janus membrane has been proposed for efficient recovery of viscous lubricant oil from emulsions. The polydopamine layer facilitates the adsorption and diffusion of oil droplets through the membrane. The optimized membrane exhibited a 70% higher accumulative flux for viscous lubricant oil compared to the contrast PVDF membrane.

Summary: In this study, a nonionic poly(N-acryloyl morpholine)-brush-grafted-poly (vinylidene fluoride) membrane (PVDF-g-PACMO) with high hydrophilicity and high permeation was successfully fabricated via surface-initiated atom transfer radical polymerisation (ATRP) to separate various surfactant-stabilised emulsions. Membrane fouling behavior varied for anionic, nonionic, and cationic surfactant-stabilised emulsions, with anionic surfactants causing severe fouling due to electrostatic repulsion, while nonionic and cationic surfactants exhibited reduced irreversible fouling. The study also revealed that the oppositely charged surface potentials of the PVDF-g-PACMO membranes compared to that of the oil/water emulsions assist in mitigating irreversible fouling.

Summary: Ceramic membranes are widely used for oil-water separation due to their high flux, excellent chemical stability, strong hydrophilicity, and good fouling resistance. This study used a co-deposition reaction to modify the surface of ceramic membranes, enhancing their anti-fouling performance. The zwitterion-functionalized ceramic membrane showed improved hydrophilicity and achieved double the permeance compared to the original membrane during the separation of oil-in-water emulsion, indicating good anti-fouling performance.

Summary: Dispersants can make the separation of oil-water emulsions challenging by reducing oil-water interfacial tension. However, at specific concentrations, dispersants can disperse a portion of the crude oil into small droplets. Complete rejection of oil in separation tests was accompanied by a flux decline due to a decrease in membrane oleophobicity.

Summary: The novelty of this work lies in the modified single walled carbon nanotube with magnetic CoFe2O4 nanoparticles and p-cyclodextrin/folic acid as a targeted delivery carrier for controlled release of anticancer active agent (chlorogenic acid). The effective factors, including pH, contact time, and nanoadsorbent dosage, were optimized using response surface methodology and central composite design. The results showed that a quadratic model was suitable for fitting the experimental data, and a maximum adsorption efficiency of 87.25% was predicted under specific conditions. The nanoadsorbent was thoroughly characterized using various techniques. The adsorption isotherm and kinetic results were well described by the Langmuir and pseudo-second-order models, respectively. The release of chlorogenic acid showed sustained release, and the release rate was influenced by pH. The cytotoxicity test confirmed the biocompatibility of the single walled carbon nanotube and nanocarrier.

Summary: pH-sensitive magnetic nanocarrier was developed for doxorubicin delivery by grafting hyaluronic acid/beta-cyclodextrin onto Fe3O4 magnetic nanoparticles. The nanocarrier demonstrated strong pH-dependent release behavior, with higher drug release at pH 5.6 compared to pH 7.4. The release mechanism was determined to be controlled by Fickian diffusion kinetic. The surface modification of the magnetic nanoparticles greatly influenced drug sorption and was more compatible with Langmuir isotherm and pseudo-second-order kinetic models. Thermodynamic parameters indicated that the doxorubicin adsorption was endothermic and spontaneous, suggesting physiochemical sorption. These findings highlight the potential of pH-sensitive nanocarriers for drug delivery.

Summary: In this study, a pH and thermosensitive polymer-modified polyethylenimine dendrimer-grafted tungsten disulfide nanocarrier was successfully synthesized for triggered letrozole delivery in cancer chemotherapy. The nanocarrier exhibited dual responsiveness, with drug release enhanced under near infrared laser irradiation. The pH and thermosensitivity of the nanocarrier were demonstrated through release experiments at different pH values and temperatures. The release of letrozole from the nanocarrier followed non-Fickian diffusion mechanism, and the adsorption of the drug on the pH and thermosensitive polymer was best explained by Langmuir isotherm and pseudo-second-order kinetic models.
