Membrane Polymers for the Pervaporative Separation of Polar Organics: Methanol and Acetonitrile

open access: yesJournal of Applied Polymer Science, EarlyView.
We tested seven polymers as membranes for the pervaporative separation of methanol‐acetonitrile mixtures. Chloroprene rubber, silicone rubber, and Matrimid showed effective separation by favoring acetonitrile transport, enabling azeotrope breaking. Plasticization was assessed using Broadband Dielectric Spectroscopy.

Real‐Time Kinetic Monitoring of Dental Composite Photopolymerization by Photo‐DSC

open access: yesJournal of Applied Polymer Science, EarlyView.
Real time photo‐DSC was used to investigate polymerization kinetics of Bis‐GMA/TEGDMA dental composites. The study thoroughly examines how photo‐initiator type, concentration, silica filler content, and moisture affect conversion and curing rate. Results highlight optimal initiator systems, filler effects, and moisture tolerance, providing valuable ...

Effect of SSZ‐13 Zeolite Loading and Synthesis Time on the CO2/N2 Separation Performance of PDMS Mixed Matrix Membranes

open access: yesJournal of Applied Polymer Science, EarlyView.
Advantages of MMMs and the Robeson plot detailing improved performance of the 4d05% membrane. ABSTRACT Mixed matrix membranes were produced by incorporation of SSZ‐13 zeolites into polydimethylsiloxane (PDMS) to assess the effect of filler properties and concentration on the CO2/N2 separation efficiency compared to pure PDMS membranes.

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Enhancing the Capacitance of Poly(Heptazine Imide) Electrodes in Aqueous Electrolytes via Hybrid Material Design

open access: yesBatteries &Supercaps, EarlyView.
This work highlights the synthesis of a potassium poly(heptazine imide) K‐PHI@carbon hybrid material. The design of the hybrid improves the electrochemical properties of the semiconducting carbon nitride enabling the investigation of interaction between K‐PHI and different cations from the electrolyte.
