Summary: The separation of oil/water emulsions has long been a focus due to their negative environmental impacts. Polyvinylidene fluoride (PVDF) membranes have advantages in terms of fabrication ease, high selectivity, and fair pore distribution. However, PVDF membranes are hydrophobic and prone to fouling, leading to a decline in flux. Adding wettable substrates during fabrication can improve fouling resistance.

Summary: Contamination of water resources with inorganic and organic pollutants, as well as microplastics (MPs), poses a significant challenge to aquatic, human, and wildlife sustainability. Nanomaterial-based adsorbents, such as metal-organic frameworks, bio-based nanomaterials, carbon-based nanomaterials, and layered double hydroxides, show promise in removing MPs from water due to their high surface area and affinity towards pollutants. However, research in this field is still in its early stages and several questions remain unanswered. Further studies are needed to fully explore the strengths, weaknesses, and future research dimensions of nanomaterial-based adsorbents for MP removal from water.

Summary: Interfacial engineering plays an important role in enhancing the performance and stability of perovskite solar cells (PSCs) by reducing non-radiative recombination and improving the moisture resistance. This study focuses on the synthesis and characterization of 2D polymeric carbon nitride-based materials as interfacial layers in inverted PSCs. These interfacial layers effectively suppress the redox reaction between Ni3+ and organic cations in perovskites, suppress interfacial charge accumulation, and reduce non-radiative recombination, leading to improved stability and higher device performance.
