Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Configuration Optimisation of Integrated Wind–PV–CSP Power Generation to Enhance Grid Support in High‐Renewable Power Systems

open access: yesIET Smart Energy Systems, EarlyView.
An 8760‐hour optimisation model is developed for integrated wind–PV–CSP systems. Full‐factorial configuration and sensitivity analyses identify a clear optimal structure under grid and turbine constraints, enabling balanced trade‐offs among economic performance, peak‐period supply capability and energy utilisation and providing practical references for

A Consideration on the Flow of Steam in Steam Turbines.

open access: yesJournal 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。

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

open access: yesFinancial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Effect of 600 MW Supercritical Steam Turbine Prolonging Running Time of Mixing Valve on Unit Vibration

open access: yes发电技术, 2019
The bearing vibration of No.2, No.3, No.4, No.5, No.6 of a 600 MW supercritical steam turbine in a power plant is relatively large. In order to solve this problem, the intake mode of the steam turbine was changed by prolonging the operation time of the ...

Organizing Buyer‐Side Scope 3 Governance: Sensemaking in Supply Network Decarbonization

open access: yesJournal of Supply Chain Management, EarlyView.
ABSTRACT For many large manufacturers and consumer brands, most greenhouse gas emissions arise outside their own operations and within supplier networks they do not fully control. However, regulators and investors increasingly expect firms to show credible progress on reducing these emissions.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
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 ...

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure

open access: yesAdvanced Energy Materials, Volume 16, Issue 33, 2 September 2026.
Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC
