Porphyrin/sPEEK Membranes with Improved Conductivity and Durability for PEFC Technology [PDF]

ACS Applied Energy Materials, 2018
Advanced composite membranes have been obtained by incorporation of the meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) into a sulfonated poly(etheretherketone) (sPEEK). The presence of porphyrins in their monomeric, dimeric, and aggregated forms into the membrane ionic domains have been investigated by static and time-resolved spectroscopic ...

Finding the Perfect Match: Investigation of 1,2‐Diketone‐Based Materials for Use as Cathode Active Material in Rechargeable Magnesium Batteries

Small, Volume 22, Issue 46, 18 August 2026.
A novel and generally applicable early screening method for 1,2‐diketones via cyclic voltammetry and DFT computations identifies phenanthrenequinone as a suitable candidate as cathode active material for use in RMB. Its successful incorporation into a polymer enabled promising lithium and magnesium battery performance.

Residence time and functional traits shape conspecific plant–soil feedback but not inferred coexistence patterns of alien and native species

Journal of Ecology, Volume 114, Issue 8, August 2026.
Illustration of the study design and key findings on the effects of residence time and functional traits on conspecific plant‐soil feedback and inferred coexistence patterns in alien and native species. Abstract Plant–soil feedback (PSF) describes changes in a plant's performance when growing in soil previously occupied by another plant, often driven ...

CO2 Detection Using Potentiometric Sensors Based on PIM‐1/DES Membranes

Advanced Sensor Research, Volume 5, Issue 7, July 2026.
The developed sensor offers high reproducibility, fast response, and reliable detection of variable CO2 levels. ABSTRACT Polymers of Intrinsic Microporosity (PIMs) are a class of polymers characterized by a native microporous network resulting in a high surface area. PIMs also display a highly tunable and efficient gas permeability, attracting a lot of
