Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study addresses limitations of the conventional dry‐pressing method for electrolyte‐supported films—smooth surfaces, excessive thickness, and fragile supports inducing damage. We propose an innovative camphor–quartz sand composite architecture to construct a five‐layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films
Advanced Physics Research, EarlyView.FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

Batteries &Supercaps, EarlyView.Magnesium (Mg) doping is explored as a stabilization strategy for high‐capacity LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes. Three doping routes are compared, revealing that solid‐state lithiation delivers the best cycling stability. Operando X‐ray diffraction and electrochemical dilatometry link reduced cation mixing and lattice stabilization to improved ...
