Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Experimental and Theoretical Investigation for Shaft Journal Bearing Lubrication Performance [PDF]
Port Said Engineering Research JournalHydrodynamic lubrication is definitely one of the foremost factors upon which the load carrying capacity within journal bearing mainly rely. Therefore, maintaining journal bearing lubrication away from boundary and transient lubrication regions is so ...

Advanced Healthcare Materials, EarlyView.Engineered nanoparticles capture disease‐specific biomolecular coronas that uncover hidden molecular features of Alzheimer's disease. Combined proteomic and lipidomic analyses reveal a characteristic shift in ribosomal machinery and energy metabolism, generating a multiomic fingerprint that supports accurate disease detection and opens new ...

Hydrodynamic Bearing Lubricated with Magnetic Fluids
Journal of Intelligent Material Systems and Structures, 2009 This article summarizes the work carried out in the development of hydrodynamic lubricated journal bearings with magnetic fluids. Two different fluids have been analyzed: one is the ferrofluid from FERROTEC APG s10n and the other is the magnetorheological (MR) fluid from LORD Corp., MRF122-2ED.

Advanced Materials, EarlyView.Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Instability studies of an 'O'-ring flexibly supported, gas bearing, mounted, cool air unit. [PDF]
, 1990 A Cool Air unit (C. A. U. ) is powered by air bled from the engine and supplies cool air to the avionics and cockpit of the aircraft. Essentially a small turbo machine, the rotor is mounted upon two plain (gas) air bearings, which are flexibly ...
