Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]

, 1985
The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Variability of Saliva Viscosity - Potential Impact

, 2022
As novel COVID-19 testing develops, saliva has become of increasing interest as an alternate biological sample for rapid testing. The appeal in saliva-based testing lies within the ease of which samples are collected, as well as patient comfort throughout the collection process.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Melt flow in a variable viscosity matrix [PDF]

Geophysical Research Letters, 1998
It is often assumed that the molten regions of planetary interiors can be modeled as a compacting viscous matrix permeated by a less viscous melt phase. In order to assess the true behaviour, it is important to test as many different aspects of these models as possible. In the calculations presented here, the matrix viscosity is made to decrease as the

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Knee Joint Assist in Seated Motion Focusing on Variable Viscosity Property in Exoskeleton Assistive Device: Comparison of Variable and Constant Viscosity Coefficients

IEEE Access
As exoskeletal assistive devices are directly attached to a person, coordination must be improved. However, existing exoskeletal assistive devices have difficulty coordinating with human behavior.

Shear viscosity of a pion gas resulting from rho pi pi and sigma pi pi interactions

, 2014
We have evaluated the shear viscosity of pion gas with vanishing chemical potential taking into account its scattering with the low mass resonances sigma and rho during propagation in the medium.

Scrutinization of Mixed Convection in Variable Viscosity Casson Nanofluid Flow Over a Stretching Sheet Subject to the Cattaneo–Christov Flux Model

International Journal of Differential Equations
This study explores mixed convection in a variable viscosity Casson nanofluid flowing over a stretching sheet, incorporating the effects of a magnetic field, viscous dissipation, and Joule heating within the framework of the Cattaneo–Christov flux model.
