Ultrahigh High‐temperature Capacitive Energy Storage Via Proton Irradiation

open access: yesAdvanced Science, EarlyView.
Proton irradiation concurrently induces enhanced dielectric constant and breakdown field in aromatic polymers with ether bonds, which enables an ultrahigh discharged energy density of 6.9 J cm−3 at above the efficiency of 95% at 150 °C, exceeding current dielectric polymers and nanocomposites.

Modeling and Measurement of Noise in Aluminium Nitride Piezoelectric MEMS

open access: yesAdvanced Electronic Materials, EarlyView.
This work analyzes electrical noise in piezoelectric AlN MEMS devices using a combined measurement‐modeling approach. The framework separates sample and amplifier noise contributions and demonstrates close agreement between model and experiment at both room and cryogenic temperatures.

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...
