Synthesis and electrochemical Li-storage performance of Li2ZrO3-Li3V2(PO4)3/C composites

open access: yesElectrochemistry Communications, 2021
A simple and efficient synthetic route was developed to obtain composites by mechanically ball-milling Li2ZrO3 (LZO) with Li3V2(PO4)3/C (LVPC). LZO improves the ionic conductivity of LVPC, compensates for the transfer of Li+ between the LVPC and the ...

Optimal Voltage Control Method for a Step Voltage Regulator Considering the Under-Load Tap Changer in a Distribution System Interconnected with a Renewable Energy Source

open access: yesEnergies, 2023
The voltage in distribution systems is controlled by the under-load tap changer of the substation and the pole transformer of the primary feeders. Recently, as one of the main countermeasures, a step voltage regulator is being introduced to solve voltage

Novel Voltage Control Method of the Primary Feeder by the Energy Storage System and Step Voltage Regulator

open access: yesEnergies, 2019
With the intention of keep the customer voltage within a nominal voltage boundary (the South Korea voltage regulation in range of 220 V ± 6% for a single phase), the SVR (step voltage regulator) method in the primary feeder has been seriously ...

Specific heat and energy for the three-dimensional O(2) model [PDF]

open access: yes, 2001
We investigate the three-dimensional O(2) model on lattices of size 8^3 to 160^3 close to the critical point at zero magnetic field. We confirm explicitly the value of the critical coupling J_c found by Ballesteros et al. and estimate there the universal

Photocatalytic Oxidation of Triiodide in UVA-Exposed Dye-Sensitized Solar Cells

open access: yesInternational Journal of Photoenergy, 2012
UVA irradiation of glass mounted dye-sensitized solar cells without UV filtration causes failure within 400 hours of light exposure. The failure mode is shown to relate to consumption of I3−, which is directly related to TiO2 photo-catalysis.
