Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

open access: yesAdvanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

Research on Experimental Method for Obtaining Independent Combustion Noise of Internal Combustion Engine

open access: yesShock and Vibration, 2018
Internal combustion engine noise sources are complex and changeable. Combustion noise is usually drowned out by mechanical noise and aerodynamic noise. Traditional noise source identification methods can only qualitatively identify combustion noise.

Combustion Process in a Spark Ignition Engine: Dynamics and Noise Level Estimation

open access: yes, 2003
We analyse the experimental time series of internal pressure in a four cylinder spark ignition engine. In our experiment, performed for different spark advance angles, apart from usual cyclic changes of engine pressure we observed oscillations.

Carbon taxes, path dependency and directed technical change: evidence from the auto industry [PDF]

open access: yes, 2012
Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between “dirty” (internal combustion engine) and “clean” (e.g.
