Summary: Membrane wetting and fouling are major challenges in membrane distillation, especially with low surface tension components in the feed. This study developed membranes with different wettability to guide membrane selection for treating these wastewaters. Superhydrophobic and superomniphobic modifications improved anti-fouling/wetting properties when the feeds had anionic and cationic surfactants. However, these modifications worsened membrane performance when the feeds contained nonionic surfactant Tween-20. The hydrophilic layer on Janus membranes showed improvement in anti-fouling/wetting abilities for emulsified oily wastewaters, while the choice of substrate was still important.

Summary: The study reports a novel method of efficiently separating oil nano-emulsions using zirconia membranes with sub-100 nm pores and superoleophobic properties. The membrane fouling behavior is dominated by a combined model of intermediate pore blocking and cake filtration, with effective mitigation under high pH conditions. Overall, the zirconia membrane demonstrates high rejection efficiency for nano-sized oil droplets and consistent separation performance for real oily wastewaters.

Summary: The effects of operating pressure, feed temperature, oil content of feed solution, and membrane surface flow rate on membrane flux, concentration multiple, and average particle size of oil droplets in the concentrated solution during the single-stage membrane concentration process were investigated. The experimental results show that optimal conditions for single-stage concentration can be determined by increasing the operating pressure, feed temperature, and membrane surface flow rate, and decreasing the oil content of the feed liquid, the concentration ratio, and the average particle size of oil droplets in the concentrated solution. Furthermore, the recovery of oil resources in emulsified oil-containing wastewater can be realized through the combination of different pore size separation membranes in multi-stage membrane concentration.

Summary: This study focuses on improving the performance of PVC membranes by adding different concentrations (0.5-1.5 wt.%) of polydopamine-modified alumina nanoparticles. The fabricated nanocomposite membranes were tested for the removal of oily wastewater in a cross-flow filtration system. Various characterization techniques were used to analyze the membranes, and it was found that the addition of 0.5 wt.% Al2O3-PDA nanoparticles resulted in increased hydrophilicity, porosity, and pure water flux. However, the mechanical strength of the membranes decreased by 33% when 1.5 wt.% Al2O3-PDA nanoparticles were added. The permeation flux of the PVC/Al2O3-PDA-0.5 sample reached 38.2 Lm(-2) h(-1) with a TOC content of 56.3 mg L-1.

Summary: This study proposes Pickering emulsions based on wax and halloysite clay nanotubes for coating silk sutures to increase their loading capacity towards eosin. The presence of halloysite/wax microspheres on the surface of silk sutures has also been explored for controlled release of hydrophobic drugs. The influence of the coating on the thermal and mechanical properties of the sutures has been studied using various techniques. In conclusion, the wax/halloysite Pickering emulsions can successfully generate hydrophobic microdomains on the surface of silk sutures, leading to enhanced flexibility and improved loading capacity towards eosin.

Summary: Operational problems in the oil industry caused by the precipitation of paraffins can be prevented by using polymeric additives. This article evaluates the use of polymeric nanocomposites as pour point reducers in different types of crude oil and finds that they are more efficient than pure poly(ethylene-covinyl acetate) (EVA) in reducing the pour point. The nanocomposites also modify the wax crystals and reduce the viscosity of the oil samples.

Summary: Geological storage with clay buffer is widely preferred for removing hazardous radioactive waste. The impact of fluid salinity and void space on the swelling behavior of barrier bentonites was examined through experiments. The findings suggest that clay swelling is suppressed at higher salinities, which affects the void-filling process.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Chitosan-Pd0 nano particles encapsulated in Al, Co-pillared montmorillonite nanocomposites were successfully synthesized using a facile one-pot heat treatment method. The Al, Co pillaring effectively expanded the surface area and generated numerous mesopores in the interlayer space of the MMt. The resultant nanocomposite exhibited similar high comprehensive catalytic performances as the one prepared by the regular divided-multistep method. The encapsulation of CS chains and doping of Co in the Al pillaring also contributed to the improved catalytic performance.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.

Summary: The interaction between talc and the depressor CMC was investigated through molecular dynamics simulation and density functional theory calculation. It was found that CMC showed stronger adsorption on the edge plane of talc due to enhanced interactions with polar groups and water molecules. The study also revealed specific interactions between H atoms in CMC and O atoms in the edge plane, as well as between O atoms in CMC and Si, Mg atoms in the edge plane. Hydration shells on the basal and edge planes of talc were examined to explain the phenomenon.
