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)

Disclosure, disbelief, enclosure: listening with precarious kids in London Témoignage, incrédulité, enfermement: écouter les enfants en situation de précarité à Londres

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article interrogates the role of testimonial disclosure as a mechanism of access and a barrier to visibility for marginal people, particularly adolescents, in the UK. Drawing on ethnographic fieldwork conducted between 2021 and 2024 in alternative educational provision (AP), as well as in English for Speakers of Other Languages (ESOL) classes ...

Is Additive Manufacturing of Dental Zirconia Comparable to Subtractive Methods When Considering Printing Orientation and Layer Thickness? A Systematic Review and Meta‐Analysis

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The aim of this systematic review and meta‐analysis was to determine whether the production of monolithic dental zirconia using additive manufacturing (AM), with consideration of different printing directions and layer thicknesses, enhances its mechanical and physical properties relative to subtractive manufacturing (SM ...
