Summary: Sulfonated poly (phenylene oxide) (SPPO)/MXene nanosheets cation exchange membranes (CEM) were prepared by solution casting technique. The effects of different sulfonation degrees (DS), polymer concentrations, and MXene loadings on the properties of CEMs were studied. The results showed that increasing DS, adding hydrophilic MXene nanosheets, and decreasing polymer concentration improved the hydrophilicity and conductivity of the CEMs. MXene nanosheets also increased the permselectivity and tensile strength of the membranes.

Summary: Electrochemical treatments in wastewater management have high potential, but the performance of ion-exchange membranes (IEMs) often limits their effectiveness. Sulfonated silica-based nanofiber cation-exchange membranes (CEMs) offer a solution to these limitations, thanks to their chemical resistance and self-cleaning properties. These nanofiber CEMs can be produced without the need for additional material and have excellent performance in lab-scale electrochemical tests, exhibiting resistance to strong acids and self-cleaning properties.

Summary: This review comprehensively covers the chemical properties and synthesis routes of CD/CTR cross-linking, as well as their applications as drug-delivery systems on different substrates. The study found that the CD/CTR biopolymers were nontoxic, environmentally friendly, and inexpensive, making them widely used in coating implants and biomedical materials. The importance of pretreatment methods on substrates and the analysis of release mechanisms, including the Korsmeyer-Peppas mathematical model, were also discussed. The flexibility of CD/CTR in hosting a wide variety of drugs, integrating with diverse implantable materials, and controllable release kinetics provide a range of advantages for future uses.

Summary: Molybdenum disulfide (MoS2) sheets were obtained by exfoliating bulk powders in a solution containing tryptophan, and then drop-casted onto a glassy carbon electrode (GCE) to form GCE/MoS2. Electrodeposition of amorphous MoSx onto the GCE was used for comparison. Both electrodes were employed for the electrochemical detection of metronidazole (MTZ), but GCE/MoS2 showed superior performance due to its larger surface area, lower charge-transfer resistance, and the presence of edges and defects that facilitated the electron transfer reaction. Impressive linear calibration curves were obtained for GCE/MoS2, with a wide concentration range and high sensitivity.
