Influence of steaming on drying quality and colour of beech timber [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2015 This paper presents the results of an analysis of influence of the “light” steaming process on conventional drying and colour of beech timber. A stack consisting of steamed and unsteamed boards was dried.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

A Consideration on the Flow of Steam in Steam Turbines.
Journal of the Society of Mechanical Engineers, 1941 多段落衝動タービンの相隣れる段落に於て、前段落の羽根より流出する蒸汽の有する速度エネルギの利用問題を中心として、タービン内における蒸汽の流動を取扱つた。就中低圧部で相隣れる二つの段落の間隙が可なりあり、且両段落の平均羽根円直径に急変を與へる場合をとつて、かゝる構造の汽室内に運轉状態の如何によつて起ることあるべき蒸汽の種々の流動状態を近似的計算によつて解析した。そして如何なる設計にすればかゝる特殊構造の段落のノズル效率を増進し、且その特性を改善し得るかを論じた。

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid
Advanced Engineering Materials, EarlyView.A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
