Digital Printing of Photoreversible Protective Films

Macromolecular Rapid Communications, EarlyView.
A photopolymerized and photoreversible temporary protective film based on an ortho‐nitrobenzyl crosslinker is presented that can be applied using aerosol jet printing. To improve adhesion to industry‐relevant surfaces, a polyethyleneimine‐based adhesion promoter was added to the aqueous formulation of diacrylate cross‐linker and acrylated macromers ...

The Influence of Hub Purge Flow Rate on Forced Response in a Low-Pressure Turbine

International Journal of Turbomachinery, Propulsion and Power
We present the results of a computational investigation into the influence of hub purge flow mass flow rate on the forcing amplitudes generated on a low-pressure turbine (LPT) rotor cascade by the upstream stator vane passing (SVP).

Orthostatic Myoclonus—Clinical and Electrophysiological Features in a Large Retrospective Cohort

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Orthostatic myoclonus is characterized by irregular, lower limb myoclonic bursts during stance and is a major cause of postural instability and falls. However, studies are limited, and little is known about its pathophysiology. Objectives We sought to define the clinical and electrophysiological features of orthostatic myoclonus in ...

Design and Multibody Dynamics Modeling of a Novel High‐Static‐Low‐Dynamic‐Stiffness Vibration Isolation Mechanism Based on Euler Buckling Characteristics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibration isolation has long been a critical area of research, with the design of isolators based on the mechanical properties of Euler buckling beams representing one of the primary approaches. Traditionally, the focus has been on utilizing the negative stiffness characteristics of a post‐buckled Euler beam in parallel with positive stiffness

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 ...
