Graphene is a single-layered sp-hybridized carbon allotrope, which is impermeable to all atomic entities other than hydrogen. The introduction of defects allows selective gas permeation; efforts have been made to control the size of these defects for higher selectivity. Permeation of entities other than gases, such as ions, is of fundamental scientific interest because of its potential application in desalination, detection and purification.

The high salt content and color are regarded as a major challenge to the reuse of industrial wastewater. In the present study, the application of cellulose acetate reverse osmosis (RO) membrane in combination with microfiltration (MF), ultrafiltration (UF), or nanofiltration (NF) process was investigated in the purification of biological and Fenton treated pulp and paper wastewater. In the first step, the effect of pH and inlet pressures on the membrane fouling was investigated.

MXenes, a family of two-dimensional transition metal carbides and nitrides, exhibit exceptional properties such as high electrical conductivity, large surface area, and chemical versatility, making them ideal candidates for various dialysis applications. One prominent application of MXenes lies in the efficient removal of toxic metals and harmful dyes from wastewater. Their unique structure allows for rapid adsorption and selective separation, significantly improving purification processes.

Serum amyloid A (SAA) is a key biomarker for diagnosing inflammatory responses in diseases like influenza and COVID-19. An electrochemiluminescence (ECL) biosensor has been constructed for signal enhancement in SAA detection by encapsulating 4,4',4″,4‴-(1,3,6,8-pyrenetetrayl) tetrakis-benzoic acid (TBAPy) into liposomes. Such biomimetic encapsulation shields the biologically important membrane to avoid aggregation of TBAPy and prevents quenching.
