Centrifugally forced Rayleigh–Taylor instability [PDF]

Journal of Fluid Mechanics, 2018
We consider the effect of high rotation rates on two liquid layers that initially form concentric cylinders, centred on the axis of rotation. The configuration may be thought of as a fluid–fluid centrifuge. There are two types of perturbation to the interface that may be considered, an azimuthal perturbation around the circumference of the interface ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Effect of Excess Gravitational Force on Cultured Myotubes in Vitro [PDF]

Journal of Systemics, Cybernetics and Informatics, 2013
An effect of an excess gravitational force on cultured myoblasts has been studied in an experimental system with centrifugal force in vitro. Mouse myoblasts (C2C12) were seeded on a culture dish of 35 mm diameter, and cultured in the Dulbecco's Modified ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Centrifugal Force Boosts Self‐Assembly of Gradient Lattice Photonic Crystals

Advanced Photonics Research
Gradient photonic crystals, compared to traditional photonic crystals, possess broader photonic bandgaps and more flexible arrangement structures. This article proposes a centrifugal force‐driven self‐assembly method for controllable construction of ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Test method for axial force at pile top in centrifugal model tests on pile-net composite foundation

Yantu gongcheng xuebao
The pile-net composite foundation is a common soft soil reinforcement measurement. In order to analyze the pile-soil stress ratio, it is necessary to measure the axial force at the pile top and the soil pressure between piles in the centrifugal model ...

Comparative study of different centrifugation protocols for a density gradient separation media in isolation of osteoprogenitors from bone marrow aspirate

Journal of Oral Biology and Craniofacial Research, 2014
Introduction: Human bone marrow contains osteoprogenitors capable of differentiating into osteoblasts. Density gradient centrifugation (DGC) is a commonly used method to isolate osteoprogenitors from bone marrow.
