Welcome to the Newberg research group website

We are a multidisciplinary surface chemistry research group tackling problems on a molecular level in energy and environmental sciences.

Research topics of interest include metal oxide interfaces, catalysis, photocatalysis, electrochemical interfaces, ionic liquid interfaces, surface chemistry of atmospheric aerosol particles, and the chemistry of ice. A major research focus in our group is understanding how water influences surface chemical transformations at solid-gas and liquid-gas interfaces.

New coauthored manuscript by 
Shavorskiy et al. in Journal of Physical Chemistry C, examining the adsorption and dissociation of molecular water on native Al2O3 films prepared on a NiAl(110) single crystal. Surface chemistry was probed in situ using ambient pressure XPS at beamline 11.0.2 ALS synchrotron at LBNL in Berkeley and post exposure morphology changes using STM at the Center for Functional Nanomaterials at BNL in Upton, NY. This manuscript is part of the John Hemminger JPC-C Festschrift.

UDRF Grant

The Newberg group has been awarded an intramural grant from the University of Delaware Research Foundation (
UDRF), with 11 total awards given to new faculty at UDel as highlighted in UDaily. This funding will help support efforts to understand the interfacial chemistry of ionic liquids in the presence of water vapor and other gases using ambient pressure XPS.

New JPC-C publication

A new manuscript has been accepted in J. Phys. Chem. C (DOI:
10.1021/jp5052613), developing the surface thermodynamics and kinetics to assess the enthalpy, entropy, Gibbs free energy, and desorption frequency factor as a function of coverage for the splitting of water at MgO(100) terrace sites under adsorption-desorption conditions using ambient pressure XPS. This manuscript is part of the John Hemminger JPC-C Festschrift.
