Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Integrity analysis of polyamide 12 applied in oil pipelines

Journal of Thermal Analysis and Calorimetry
Abstract Pipes of polyamide were installed in oil fields and, after one year of operation, were removed and analyzes were carried out to assess any degradation and study its use in oil pipelines as corrosion mitigation. The outer layers of all field samples and the unaged sample did not show, in the DSC, any primary peak close to the melting ...

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

FlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...
