Background Bisphenols, particularly bisphenol A (BPA), are the primary monomers used as
additives in the manufacturing of many consumer products. The exposure to these …

Enriching and detecting the trace pollutants in actual matrices are critical to evaluating the
water quality. Herein, a novel nanofibrous membrane, named PAN-SiO 2@ TpPa, was …

A magnetic covalent organic framework (COF) was constructed with ethidium bromide (EB)
and 1, 3, 5-triformylphloroglucinol as building blocks. The prepared magnetic COF (named …

Over years, magnetic materials have gained special attention since they offer a versatile and
