Voltammetry under a Controlled Temperature Gradient [PDF]

open access: yesSensors, 2010
Electrochemical measurements are generally done under isothermal conditions. Here we report on the application of a controlled temperature gradient between the working electrode surface and the solution.

An Insight to the Degradation Behaviour of the Parallel Connected Lithium-Ion Battery Cells

open access: yesEnergies, 2021
In an electric vehicle, a large number of lithium-ion cells are connected in parallel. While cells in parallel increase the reliability of the battery pack, it increases the probability of current imbalance between the parallel branches, thus ageing ...

Simulation and Experiment for Growth of High-Quality and Large-Size AlN Seed Crystals by Spontaneous Nucleation

open access: yesSensors, 2020
Seed crystals are the prerequisite for the growth of high quality and large size aluminum nitride (AlN) single crystal boules. The physical vapor transport (PVT) method is adopted to grow AlN seed crystal. However, this method is not available in nature.

An adiabatic piston in a temperature gradient [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2012
The steady states of two gases of hard spheres or disks separated by an adiabatic piston in presence of a temperature gradient are discussed. The temperature field is generated by two thermal walls at different temperatures, each of them in contact with one of the gases.
