Effects of B‐Site Nb Substitution on ORR Activity in Perovskite Cathode Materials for Solid Oxide Fuel Cells

open access: yesSusMat, EarlyView.
B‐site Nb substitution in PSCF perovskite cathodes modulates oxygen vacancy formation and electronic structure, thereby tailoring oxygen adsorption and ion transport properties. A moderate Nb level (5–10%) optimizes the balance between surface activity and conductivity, enhancing ORR kinetics and SOFC performance. ABSTRACT Solid oxide fuel cells (SOFCs)

Optimizing Hard and Soft‐Tissue Esthetics With Anterior Cantilever Zirconia Ceramic Resin‐Bonded Fixed Dental Prostheses

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The replacement of missing maxillary lateral incisors poses both functional and esthetic challenges, not only from a restorative but also from a periodontal aspect. This case report presents a step‐by‐step protocol for ideal hard and soft‐tissue esthetics with cantilever zirconia ceramic resin‐bonded fixed dental prostheses (RBFDPs).
