Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Surface modification of polysulfone ultrafiltration membrane by oxygen plasma treatment

open access: yes, 2019
Oxygen plasma treatment was used to change the hydrophobic polysulfone ultrafiltration membrane to the hydrophilic membrane. The contact angle of water decreased with increasing the oxygen plasma treated time of polysulfone membrane and was saturated ...

Revisiting the Carbon Footprint of Single‐Use Technologies in Biomanufacturing: A Bottom‐Up Analysis Reveals a Paradigm Shift

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 10, Page 2802-2814, October 2026.
ABSTRACT The biopharmaceutical industry increasingly relies on single‐use technologies (SUT) for operational flexibility. For a long time, SUT was considered more sustainable than stainless‐steel (SST) systems due to water and energy savings. This study re‐evaluates this paradigm via a detailed bottom‐up analysis of the SUT carbon footprint at the 2000
