A concentric hydrodynamic journal bearing with the boundary slippage

Journal of Theoretical and Applied Mechanics, 2016
The paper proposes a concentric hydrodynamic journal bearing constructed by the boundary slippage, which is opposed by conventional lubrication theory. Analysis for the carried load and friction coefficient of this bearing is presented. The optimum condition for the maximum load-carrying capacity of this bearing is examined.

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Numerical Analysis of a Hydrodynamic Herringbone Grooved Journal Bearing

Journal of Engineering, 2020
In hydrodynamic lubrication, at very high rotational speed, the phenomenon of axial fluid leakage is often present. This can involve an increase of shear stress in the contact and consequently a considerable increase of the temperature.

Assessment of polymer composites for hydrodynamic journal‐bearing applications

Lubrication Science, 2009
AbstractPolymer composites are used as facing materials in hydrodynamic bearings for their low friction and ‘compliant’ properties, which play an important role during machinery operation. In journal bearings, this low friction property can be of significant importance during start and stop cycles when insufficient oil is available to fully separate ...

Deep Mutational Scanning for the Study and Engineering of Protein Assemblies

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review explores how deep mutational scanning (DMS) can be used to improve understanding and accelerate engineering of protein assemblies, from natural fibers to engineered nanocages. We discuss various types of protein assemblies and their characterization, provide an introduction to the DMS technique, and then highlight examples in which DMS has ...

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, Volume 38, Issue 5, Page 301-326, August 2026.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Standardized Effect Measures Informing Next‐Generation Strategies for Mechanical Stimulation in Cartilage Tissue Engineering

Advanced Healthcare Materials, Volume 15, Issue 26, 10 July 2026.
This systematic review quantitatively compares conventional mechanical stimulation strategies in cartilage tissue engineering across 85 heterogeneous in vitro studies. Applying standardized effect measures, meta‐analysis reveals that combined compression and shear loading optimally promotes cartilage matrix development.
