Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

The research progress in polyethylene oxide polymer electrolytes

open access: yesFlexMat, 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 ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

open access: yesMacromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...
