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 Efficacy Of Glass Ionomer Hybrid As Orthodontic Brackets Adhesives To Inhibit Calsium Released Of The Enamel

open access: yesInsisiva Dental Journal, 2012
Composite resins are predominantly used to bond orthodontic brackets onto teeth. These can lead to calcium released of the enamel surrounding the brackets.

Leptin Reduces Running in a Rodent Anorexia Nervosa Model via a Distributed Neural Network

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Hyperactivity is a persistent and clinically relevant symptom in anorexia nervosa (AN). Hyperactivity is inversely correlated with leptin levels. While systemic leptin administration attenuates hyperactivity in rodent models, the specific brain regions mediating this effect remain unclear.

Glass ionomer cements: an investigation into ionic processes within the cement with respect to time

open access: yes, 2010
PhDA series of experiments were performed to understand the ionic processes in glass ionomer cements. Fluoride release from fluoroaluminosilicate glasses in deionised water and artificial saliva Inorganic artificial saliva was used to compare the ...

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 ...

Radiopacity Of Glass-ionomer/composite Resin Hybrid Materials. [PDF]

open access: yes, 2015
This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium ...

Perceived Educational Value of a Self‐Developed 3D‐Printed Pediatric Dentistry Simulator

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Purpose To design and assess a 3D‐printed pediatric dentistry simulator and to evaluate its perceived educational value and realism through student and expert feedback. Methods A maxillary simulator that is mountable on phantom heads was developed and produced by desktop stereolithography with single‐use inserts, enabling proximal caries ...

Deformation, Creep, and Dynamics in Glassy Ionomers

open access: yesJournal of Polymer Science, EarlyView.
Ionic architecture tunes the inelastic deformation of glassy ionomers. Simulations show that ionic associations leave the small‐strain elastic baseline nearly unchanged, but strongly reinforce yielding, strain hardening, and creep resistance. Polyampholyte architectures suppress nonaffine mobility and stress‐induced fluidization most effectively by ...

Evaluation of wear resistance and fluoride release from glass ionomer covered with nanofilled self-adhesive coat: An in vitro study

open access: yesCaspian journal of dental research, 2021
Introduction: The resin-modified glass ionomer (RMGI) materials are hybrid materials including conventional glass ionomer and small addition resin. They have the advantages of both, such as adhesion to tooth structure, esthetics and fluoride release. The
