Успехи физики металловThe paper analyses the hardening of binary and multicomponent solid solutions (including high-entropy alloys (HEAs)); addresses the notion of a compositional–cluster structure of binary solid solutions with unlimited solubility to propose an equation ...

Viscoelastic capillary flow: the case of whole blood
AIMS Biophysics, 2016 The dynamics of spontaneous capillary flow of Newtonian fluids is well-known and can be predicted by the Lucas-Washburn-Rideal (LWR) law. However a wide variety of viscoelastic fluids such as alginate, xanthan and blood, does not exhibit the same ...

Bubble clouds in viscoplastic fluids [PDF]
arXiv, 2021 Viscoplastic fluids can hold bubbles/particles stationary by balancing the buoyancy stress with the yield stress. In the present study, we investigate a suspension of bubbles in a yield-stress fluid. More precisely, we compute how much the gas fraction $\phi$ that could be held trapped in a yield-stress fluid without motion.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions
FEBS Letters, EarlyView.This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

Plastic o pseudoplastic?. Methods for determining and analising the yield stress of ceramic slips
Boletín de la Sociedad Española de Cerámica y Vidrio, 2000 In the last years the use of rheometric techniques like control stress and oscillation measurements has become popular. In this work the basic concepts of suspensions rheology are revised and the recent rheometric techniques for their complete ...

New Driving Unit for the Direct Measurement of Yield Stress with a Stress Controlled Rheometer
Applied Rheology, 2008 Investigations of rheological properties of ferrofluids have shown strong changes of the viscosity in magnetic fluids with an applied magnetic field. The change of the viscosity – the magnetoviscous effect – can theoretically be described with chain and ...

Acoustic bubble dynamics in a yield-stress fluid
Soft Matter, 2020 Bubbles initially trapped in a yield-stress fluid can be displaced by acoustic forces and exhibit shape oscillations at higher acoustic pressure, but irreversible motion is not observed.

FEBS Letters, EarlyView.Low‐density lipoprotein receptor‐related protein 6 (LRP6) is a key receptor for the Wnt antagonist Dickkopf1 (DKK1). DKK1 protein expression is induced in a bleomycin (BLM)‐induced lung injury model. We show that DKK1 induces proinflammatory and profibrotic genes in lung fibroblasts.
