Here, a highly efficient membrane based on electrospun polycyclodextrin (poly-CD) nanofibers was prepared and exploited for the scavenging of various polycyclic aromatic hydrocarbons (PAHs) and heavy metals from water. The poly-CD nanofibers were produced by the electrospinning of CD molecules in the presence of a cross-linker (i.e., 1,2,3,4-butanetetracarboxylic acid), followed by heat

Cellulose acetate phthalate is a mixed ester of cellulose commonly used as a pharmaceutical excipient for enteric coating of tablets and capsules [6]. Ultrafine cellulosic (glycol/cellulose) composite fibers show high latent heat of fusion and crystallization; this shows a maximum in the efficiency of enthalpy and indicates
or filter unit. Surfactant-free cellulose acetate membranes with very low levels of extractables are available on some Corning® syringe filters. Cellulose nitrate (CN) membranes are recommended for filtering solutions where protein binding is not a concern. They are recommended for use in general laboratory applications such as buffer filtration.
