Emergent thermophoretic behavior in chemical reaction systems

Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang

Exposing a solution to a temperature gradient can lead to the accumulation of particles on either the cold or warm side. This phenomenon is known as thermophoresis, and its microscopic origin is still debated. Here, we show that thermophoresis can be obser ...

Fluctuation Relations for Dissipative Systems in Constant External Magnetic Field: Theory and Molecular Dynamics Simulations

Sara Bonella, Alessandro Coretti

We illustrate how, contrary to common belief, transient Fluctuation Relations (FRs) for systems in constant external magnetic field hold without the inversion of the field. Building on previous work providing generalized time-reversal symmetries for syste ...

Non-equilibrium kinetics and trajectory thermodynamics of synthetic molecular pumps

Cristian Pezzato

A major goal in the design of synthetic molecular machines is the creation of pumps that can use the input of energy to transport material from a reservoir at low chemical potential to a different reservoir at higher chemical potential, thereby forming and ...

Fluctuation relations for systems in a constant magnetic field

Sara Bonella, Alessandro Coretti

The validity of the fluctuation relations (FRs) for systems in a constant magnetic field is investigated. Recently introduced time-reversal symmetries that hold in the presence of static electric and magnetic fields and of deterministic thermostats are use ...

Energy Relaxation and Thermal Diffusion in Infrared Pump-Probe Spectroscopy of Hydrogen-Bonded Liquids

Michele Ceriotti

Infrared pump-probe spectroscopy provides detailed information about the dynamics of hydrogen-bonded liquids. Due to dissipation of the absorbed pump pulse energy, thermal equilibration dynamics also contributes to the observed signal. Disentangling this c ...

A Fully Integrated 60 mV Cold-Start Circuit for Single Coil DC-DC Boost Converter for Thermoelectric Energy Harvesting

Maher Kayal, François Krummenacher, Mathieu Yves Hervé Coustans

Harvesting energy from ambient energy sources, such as thermal gradients is one solution to address the dramatic increase in energy consumption of personal electronics. While in the field, energy abundantly available in form of heat. The use of primary cel ...

EEG microstates and the schizophrenia spectrum: evidence for compensation mechanisms

Michael Herzog, Christine Mohr, Maya Roinishvili, Ophélie Gladys Favrod, Patricia Figueiredo

Introduction: Electroencephalogram (EEG) microstates are on-going scalp potential configurations that remain stable for around 80 ms (1). Four recurrent and dominant classes of microstates (labeled A-D) are observed in resting-state EEG, explaining around ...

Design and optimization of a high-temperature latent heat storage unit

Sophia Haussener, Ehsan Rezaei, Alberto Ortona, Maurizio Barbato

High-temperature latent heat thermal energy storage systems offer compact storage solutions, benefiting from the large latent heat of phase change materials. Common challenges in their design process are the low thermal conductivity of the phase change mat ...

V-band nanosecond-scale pulse reflectometer diagnostic in the TCV tokamak

Stefano Coda, Laurie Porte, Pedro Andres Molina Cabrera

This article describes the realization of a novel approach to short pulse (∼1 ns) reflectometry (SPR) recently implemented in the tokamak configuration variable tokamak. Taking advantage of a fast arbitrary waveform generator and vector-network-analyzer ex ...

EEG microstates in schizophrenia: a candidate endophenotype

Michael Herzog, Christine Mohr, Maya Roinishvili, Ophélie Gladys Favrod, Patricia Figueiredo

Objective: Electroencephalogram (EEG) microstates are on-going scalp potential configurations that remain stable for around 80 ms. Abnormal temporal dynamics of specific classes of microstates have been suggested as a potential endophenotype for schizophre ...
