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