Ultrasonic Spray Pyrolysis‐Derived LSCF‐GDC Nanocomposites as Durable Oxygen Electrodes for Solid Oxide Electrolysis Cells

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Solid oxide electrolysis cell (SOEC) technology is a promising route for efficient and clean green hydrogen production because of its high conversion efficiency and the use of precious‐metal‐free catalysts. However, developing oxygen electrodes that combine high electrochemical activity with robust long‐term operational stability remains ...

Organometallic Solution and Surface Routes to Highly Dispersed Carbon Nanotube‐Based Fe–N–C Electrocatalysts

Small Structures, Volume 7, Issue 11, November 2026.
Isolated Fe–N–C sites embedded in an extended 3D carbon framework are accessible under ambient conditions without pyrolysis for the first time. 57Fe Mössbauer, XANES, and EPR spectroscopy reveals iron in intermediate Fe>2+ and Fe3+ spin states with long‐range magnetic coupling between iron centers which are catalytically active in ORR.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 11, Page 2177-2191, November 2026.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Comparative Evaluation of Spark Plasma and Conventional Sintering of NiO/YSZ Layers for Metal-Supported Solid Oxide Fuel Cells

High Temperature Materials and Processes, 2018
NiO/YSZ anode layers for metal-supported solid oxide fuel cells (MS-SOFCs) were fabricated by spark plasma sintering (SPS). SPS parameters were optimized in order to achive anodes of the desired microstructure.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
