Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Surfactant–Polymer Composition for Selective Water Shut-Off in Production Wells

open access: yesGels
Today, a significant part of production wells’ stock has a high water cut percentage of 90% and above. Obviously, for this reason, the need to develop new and improved existing technologies for water shut-off in wells increases every year.

Hydrodynamic Electron Flow and Hall Viscosity. [PDF]

open access: yesPhysical Review Letters, 2017
In metallic samples of small enough size and sufficiently strong momentum-conserving scattering, the viscosity of the electron gas can become the dominant process governing transport.

Robocasting of a Water‐Based Biopolymer/WO3 Nanopowder Paste as a Precursor to Tungsten Carbide Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates a novel, additive manufacturing approach to produce complex, porous tungsten carbide structures using water‐based direct ink writing/robocasting. Leveraging a modified commercial printer and heat treatment, the process yields lightweight, electrically conductive 3D architectures capable of supporting a mechanical load.

THE VISCOSITY OF THE BLOOD [PDF]

open access: yesJournal of the American Medical Association, 1908
When a fluid traverses a straight tube of sufficient length the individual molecular constituents arrange themselves eventually parallel to the long axis of the tube. Moreover, the cylinder of fluid does not move forward as one unit, but in such a manner that the central portion attains the greatest speed of flow, while the more external layers show a ...

Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed

The Minima of Viscosities

open access: yesMaterials
The Trachenko–Brazhkin equation of the minimal possible viscosity is analysed, emphasising its validity by the account of multibody interactions between flowing species through some effective masses replacing their true (bare) masses. Pressure affects the effective masses, decreasing them and shifting the minimal viscosity and the temperature at which ...

Graphene–Catechol Dental Sealant: Antibacterial and Mechanical Evaluation

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents dental sealants made with graphene and L‐DOPA‐modified graphene. L‐DOPA enhances graphene dispersion, improving sealant properties. The material shows antibacterial activity against S. mutans and L. casei, along with high strength and elasticity.
