Summary: A superhydrophobic surface of polytetrafluoroethylene (PTFE) was successfully prepared by ball milling and spraying. The low surface energy and micro-nano secondary structure contribute to the spherical shape of droplets and the higher contact angle. The contact angle of PTFE plate sprayed with 3% graphene/hydrophobic nano-SiO2 composite powder is 161.05 degrees. This approach provides a feasible way for the preparation of superhydrophobic surfaces and reduces the cleaning cost of PTFE surfaces.

Summary: Membrane distillation (MD) is an important technique for brine desalination and wastewater treatment. Researchers have found that depositing a layer of polysiloxane nanofilaments on microporous membranes can increase the distillation rate and reduce membrane wetting and fouling. Compared to conventional hydrophobic membranes, these multiscale porous membranes exhibit superior fouling resistance and achieve higher distillation flux without the use of fluorinated compounds.

Summary: Membrane-aerated biofilm reactor (MABR) is an innovative technology that solves aeration issues in traditional bioreactors. It uses a membrane to provide oxygen to biofilm grown on its surface, allowing bubbleless aeration with high oxygen transfer rates. MABR can also achieve nitrification-denitrification simultaneously due to counter-diffusion. The control of biofilm thickness is crucial for MABR performance and various methods have been proposed, along with the importance of membrane properties and configuration. MABR shows high pollutant removal rates in different wastewater treatments, including full-scale plants.

Summary: As the world population continues to grow, there is rising concern about the pollution of water bodies caused by pharmaceuticals, particularly non-steroidal anti-inflammatory drugs (NSAIDs). Metal-organic frameworks (MOFs) have emerged as an attractive alternative adsorbent due to their tailorability and high adsorption capacity. In this study, three water-stable, free-base porphyrin MOFs were investigated for diclofenac adsorption. It was found that MOF-525 showed the highest adsorption capacity, followed by MOF-545 and NU-902.
