Crystal Growth of Group IV Transition Metal Di- and Tritellurides

A significant amount of research has focused on the synthesis, characterization, and properties of 2D and quasi-1D layered materials since graphene’s remarkable discovery in 2004. Specifically, researchers have gravitated towards low-dimensional materials as the most promising way to construct cheaper and faster devices that can improve state-of-the-art silicon-based technology within the electronics industry.

Magmas and volcanoes: Decoding the chemical signals leading to magma unrest and eruption

Volcanologists strive to forecast the likelihood, magnitude, and style of eruptions. The competition between gas retention and release exert a major control on magma ascent and eruption, but the mechanisms to predict volcanic eruptions remain unresolved. To contribute to this grand challenge, I apply volcano petrology as a forensic discipline to reconstruct the dynamics of magma ascent in the Earth’s interior and the eruption dynamics of active volcanoes.

In Situ Transmission Electron Microscopy for Li-ion and Beyond-Li Batteries

Energy storage is an essential enabler for future sustainable technologies by linking renewable resources with the power grid. Following the great success of rechargeable lithium-ion batteries in the commercial consumer electronics market, the increasing demand for improved energy density, lifetime, and safety in large-scale and power-intensive device applications calls for new materials with novel structures.

A Helium Nanodroplet Instrument for Infrared Spectroscopy of Molecular Ions

Helium nanodroplets provide a cold, inert, and optically transparent environment for doping atomic and molecular species. Helium's weak interaction with dopants is minimally perturbing, and facilitates the collection of high-resolution vibrational and rotational spectra. An instrument was designed that facilitates the ionization of dopant molecules using resonant two-photon ionization. Excitation of the molecular ions then occurs using a tunable OPO/OPA infrared laser.
