Sonication‐Assisted Palladium Nanogaps in a Capacitive Structure: A Tunable and Reliable Solution for Sensitive Hydrogen Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

Baseline measurements of ethene in 2002: Implications for increased ethanol use and biomass burning on air quality and ecosystems [PDF]

open access: yes, 2012
While it is well known that combustion of ethanol as a biofuel will lead to enhanced emissions of methane, ethene (ethylene), acetaldehyde, formaldehyde, and oxides of nitrogen (primarily NO) when compared to gasoline alone, especially during cold starts

Can the U.S. Ethanol Industry Compete in the Alternative Fuels' Market? [PDF]

open access: yes
The U.S. ethanol fuel industry has experienced preferential treatment from federal and state governments ever since the Energy Tax Act of 1978 exempted 10% ethanol/gasoline blend (gasohol) from the federal excise tax.

THE POTENTIAL VIABILITY OF BIOMASS ETHANOL AS A RENEWABLE FUEL SOURCE: A DISCUSSION [PDF]

open access: yes
Much attention has been paid to alternative fuel sources of late. Ethanol has been a politically popular alternative fuel additive and has recently been pushed to the forefront as a leading replacement to MTBE as an oxygenate.

A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection

open access: yesAdvanced Functional Materials, EarlyView.
A non‐contact light‐induced droplet manipulation strategy fueled by mid‐infrared (MIR) light irradiation is introduced. No additional additives and/or complex substrate are required. Here, thermocapillary convection, directly generated by temperature gradient at outer surface of droplet via localized surface heating, plays a key role to propel the ...
