Advanced Engineering Materials, EarlyView.Additive manufacturing is a promising route for the production of Ni‐base superalloys for turbine applications, such as Inconel 718. Nonetheless, it induces various changes in the microstructure and performance of these materials. One such change is the incidence of the δ‐Ni3Nb phase, whose impact on microstructure, aging precipitate fractions, and ...

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel
Advanced Engineering Materials, EarlyView.The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

JAMA: The Journal of the American Medical Association, 1889 To the Editor: —Noticing the article in the lastJournal, by Sara A. Kime, M.D., "The Migration of a Needle," calls to my mind a case that came under my own observation about twenty-eight years ago, in the village of Warsaw, Western New York, where I was then practicing. I was called to attend Mr.

Advanced Engineering Materials, EarlyView.Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived
