Optimizing the Performance of Printed Indium Oxide Thin‐Film Transistors through Gallium Incorporation

physica status solidi (a), EarlyView.
This study reports gallium incorporation into indium oxide nanoparticle inks for low‐temperature fabrication of electrolyte‐gated transistors. Electrical analyses reveal threshold voltage modulation and suppressed leakage currents, due to the incorporation of gallium.

Wafer Scale N‐Doped Diamond (111) with Mainly Nitrogen Spin Bath Limited Nitrogen Vacancy Coherence Times from Heteroepitexial Growth

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Diamond is grown heteroepitaxially on Ir/YSZ/Si(111) wafers with a diameter of 50.8 mm. The film received a nitrogen‐doped cap. Here you see a micrograph of the cleaving edge of such N‐doped heterodiamond aligned with a photoluminescence map of the nitrogen vacancy NV0/NV− charge ratio.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Effect of primer composition on zirconia surface properties and bond strength

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the effects of different surface treatments on surface roughness, wettability, and shear bond strength of 3Y‐TZP (yttria‐stabilized tetragonal zirconia polycrystal). A total of 180 specimens (6 × 6 × 2 mm) underwent sandblasting with 50 µm Al2O3 and were divided into six groups: (i) control (no treatment), (ii) 10‐MDP +
