Resin modified glass‐ionomers: Strength, cure depth and translucency [PDF]

Australian Dental Journal, 2002
AbstractBackground: According to the classification suggested by McLean, Wilson and Nicholson only three materials, currently marketed, fit the designation of resin modified glass‐ionomers. These materials will undergo an acid/base setting reaction but also contain a limited quantity of a monomer that will polymerize as a result of irradiation.

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

ENERGY &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.

Resin-modified glass ionomer cements for bonding orthodontic retainers [PDF]

The European Journal of Orthodontics, 2009
The aims of this study were to evaluate the shear bond strength (SBS), fracture mode, and wire pull out (WPO) resistance between resin-modified glass ionomer cement (RMGIC) and conventional orthodontic composite used as a lingual retainer adhesive. Forty lower human incisors were randomly divided into two equal groups.

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 ...
