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 ...

A Study of the Minimum Thermal Power of a Nuclear Reactor

open access: yesJournal of Nuclear Engineering, 2021
The minimum mass for a critical reactor is well studied whereas the minimum heat production from a nuclear reactor has received little attention. The thermal power of a (sub)critical reactor originates from fission as well as radioactive decay.

Post-training load-related changes of auditory working memory: An EEG study [PDF]

open access: yes, 2020
Working memory (WM) refers to the temporary retention and manipulation of information, and its capacity is highly susceptible to training. Yet, the neural mechanisms that allow for increased performance under demanding conditions are not fully understood.

Opportunities for and challenges to further reductions in the “specific power” rating of wind turbines installed in the United States [PDF]

open access: yes, 2021
A wind turbine’s “specific power” rating relates its capacity to the swept area of its rotor in terms of Watt per square meter. For a given generator capacity, specific power declines as rotor size increases.

A Vehicle Noise Specific Power Concept [PDF]

open access: yes2020 Forum on Integrated and Sustainable Transportation Systems (FISTS), 2020
The main purpose of this work is to develop a single vehicle noise emission model that uses speed as input variable and returns as output a parameter directly referable to the noise source, namely the source sound power level (L w ). The model was tested on three light-duty vehicles with different motorizations: diesel, gasoline and gasoline-electric ...

Influence of Specific Power on the Solid and Liquid Products Obtained in the Microwave-Assisted Pyrolysis of End-of-Life Tires

open access: yesEnergies, 2022
In this work, chemical recycling as an alternative to conventional end-of-life treatments was studied. Two different types of end-of-life tires (ELT), truck tires and mix tires (50:50 mixture of passenger car and truck tires), were pyrolyzed in a batch ...
