Protective Effects of Er:YAG Laser and PRG Pro‐Care Gel on Enamel Demineralization

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Bioactive surface pre‐reacted glass‐ionomer (S‐PRG) technology and high‐power laser irradiation have been investigated as promising preventive approaches. S‐PRG particles exhibit multifunctional bioactive glass properties, with the ability to release and recharge ions.

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

Macromolecular 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 ...

Influence of sulfonation degree and deposition technique on the electrical and morphological properties of sulfonated polystyrene thin films

Polymer International, EarlyView.
Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.

Evaluation of the effect of desensitizing agents on the retention of complete cast crowns: An in vitro study

SRM Journal of Research in Dental Sciences, 2014
Purpose: Dentin desensitizing agents are commonly used in dental practice. But their effect on crown retention have been anecdotal. This study compared and evaluated the effect of two desensitizing agents on the retention of cast crowns cemented with ...

Deformation, Creep, and Dynamics in Glassy Ionomers

Journal 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 ...

Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

Small, EarlyView.
Perovskites are emerging as catalysts for acidic oxygen evolution in proton exchange membrane water electrolyzers. This manuscript focuses on catalyst behavior under device‐relevant conditions, highlighting surface reconstruction, elemental utilization, and membrane electrode assembly performance. By linking materials design with electrolyzer operation,

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.
