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.

Experimental analysis of gradient of negative temperature for polypropylene fiber concrete U-shaped girder [PDF]

open access: yesMATEC Web of Conferences, 2020
To study the negative temperature gradient models of a rail transit U-shaped girder during the winter season, a U-shaped rail transit girder was researched in Qingdao. The temperature field of the midspan section was observed for a 48-h period during the

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 ...

Temperature-Gradient-Driven Magnetic Skyrmion Motion [PDF]

open access: yesPhysical Review Applied, 2022
The static and dynamic properties of skyrmions have recently received increased attention due to the potential application of skyrmions as information carriers and for unconventional computing. While the current-driven dynamics has been explored deeply, both theoretically and experimentally, the theory of temperature gradient-induced dynamics ...

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.
