Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Neural network pressure identifier of a pumping unit with asynchronous electric drive of a centrifugal pump

Omsk Scientific Bulletin
The article considers the development of a pressure identifier for a pumping unit with an asynchronous electric drive. The widespread use of such installations determines the relevance of this subject. The purpose of the study is to develop a pressure identifier for a pumping unit as a part of an electrical complex based on neural ...

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

Strategic 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.

3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

Small, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

Small, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.
