Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

open access: yesPolymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

open access: yesSedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...
