New JACS paper on multiple branching pathways in pinene autoxidation

Congratulations to recently minted Dr. Melissa Meder’s lead-author paper on employing autoxidation studies on selectively deuterated alpha-pinene to reveal the importance of multiple branching pathways.

Amani’s and Nicole’s hydrothermal “Blueprint” paper out in JACS

Congratulations to Amani and Nicole, whose paper on the total potential and interfacial structure at silica:water interfaces under hydrothermal conditions was just accepted at JACS – it’s also a blueprint for how to build a phase-resolved SHG spectrometer for under $50k!

Our hematite water oxidation work with PNNL and ANL now out at Nature Communications

We’re on a roll: this is our second e-chem paper, this time on nanolayer hematite semiconductor anodes, showing that water flipping appears to be applicable to more materials classes than just metals – it also makes an important step towards elucidating causality in catalytic efficiency and the net work associated with water flipping.

New JPC Paper on PFOAs at Mineral:Water Interfaces Quantifies Surface Potential and Counts Stern Layer Water Molecules

Our new JPC A paper counts Stern layer water molecules and quantifies total surface potentials for silica:water interfaces in contact with various alkali earth chlorides and the monovalent surfactants CTAB, PFOA, and PFOS.
