Article Synopsis

  • Researchers are focusing on efficiently removing per- and polyfluoroalkyl substances (PFAS) from water, especially short-chain PFAS which are difficult to eliminate using traditional methods.
  • A new β-cyclodextrin-modified graphene oxide membrane (GO-βCD) has been developed with nanochannels that strongly bind to PFAS, significantly hindering their transport through the membrane.
  • This membrane has shown over 90% retention of PFAS from mixtures, outperforming traditional polyamide membranes and demonstrating effective long-term operation for removing PFAS from water.

Nucleic acid transport through protein-based pores is a well-characterized phenomenon due in part to advancements in nanopore sequencing. A less studied area is nucleic acid transport through extended protein-based channels, where the additional surface area and increased contact time allow for the study of prolonged binding interactions. Porous protein crystals composed of "CJ", a putative polyisoprenoid-binding protein from , represent a favorable, highly ordered material for studying DNA transport and binding/unbinding along protein-based channels.

Remediation of poly- and perfluoroalkyl substances (PFAS) contaminated soils - To mobilize or to immobilize or to degrade?

Poly- and perfluoroalkyl substances (PFASs) are synthetic chemicals, which are introduced to the environment through anthropogenic activities. Aqueous film forming foam used in firefighting, wastewater effluent, landfill leachate, and biosolids are major sources of PFAS input to soil and groundwater. Remediation of PFAS contaminated solid and aqueous media is challenging, which is attributed to the chemical and thermal stability of PFAS and the complexity of PFAS mixtures.
