The observation of high hypotonicity manipulating cell division

open access: yesHeliyon, 2019
We report a morphological manipulation of cell division which was achieved by changing the environment from isotonic to highly hypotonic. Cells at telophase were observed to undergo a morphological reversal to anaphase, with the contractile ring being ...

Heat transport in mesoscopic systems [PDF]

open access: yesSuperlattices and Microstructures, 1998
Phonon heat transport in mesoscopic systems is investigated using methods analogous to the Landauer description of electrical conductance. A "universal heat conductance" expression that depends on the properties of the conducting pathway only through the mode cutoff frequencies is derived.

Non-Local Vectorial Internal Variables and Generalized Guyer-Krumhansl Evolution Equations for the Heat Flux

open access: yesEntropy, 2023
In this paper, we ask ourselves how non-local effects affect the description of thermodynamic systems with internal variables. Usually, one assumes that the internal variables are local, but that their evolution equations are non-local, i.e., for ...

Full energy sector transition towards 100% renewable energy supply: Integrating power, heat, transport and industry sectors including desalination

open access: yes, 2020
Transition towards long-term sustainable energy systems is one of the biggest challenges faced by the global society. By 2050, not only greenhouse gas emissions have to be eliminated in all energy sectors: power, heat, transport and industry but also ...

Vibration-induced boundary-layer destabilization achieves massive heat-transport enhancement

open access: yesScience Advances, 2020
We conceptualize an elegant mechanism of thermal vibrational turbulence that achieves massive heat-transport enhancement. Thermal turbulence is well known as a potent means to convey heat across space by a moving fluid.

Numerical Simulation of Heat Transport Problems in Porous Media Coupled with Water Flow Using the Network Method

open access: yesEnergies, 2021
In the present work, a network model for the numerical resolution of the heat transport problem in porous media coupled with a water flow is presented. Starting from the governing equations, both for 1D and 2D geometries, an equivalent electrical circuit

Direct observation of large electron–phonon interaction effect on phonon heat transport

open access: yesNature Communications, 2020
As a foundational concept in many-body physics, electron–phonon interaction is essential to understanding and manipulating charge and energy flow in various electronic, photonic, and energy conversion devices.

Prediction of Leidenfrost Temperature in Spray Cooling for Continuous Casting and Heat Treatment Processes

open access: yesMetals, 2020
Spray cooling of hot steel surfaces is an inherent part of continuous casting and heat treatment. When we consider the temperature interval between room temperature and for instance 1000 °C, different boiling regimes can be observed.
