Dual comb spectroscopy is a high-resolution technique that requires two frequency combs with very similar spectral characteristics. Most examples of dual comb spectroscopy in the literature use two lasers with the same architecture. Dual comb spectroscopy is a comb tooth resolved technique, which means the frequency resolution is generally less than 100 kHz, however these comb teeth are spaced MHz to GHz apart.

Gas phase nanoparticle formation is a highly complex process that transforms small molecules and radicals into solids that impact many aspects of our lives. These impacts may be positive (high value materials, commodity chemicals etc.) or negative (pollutants). Developing robust chemical mechanisms describing the formation of nanoparticles is critical to controlling the formation of desired species and the optimization of processes. Production of carbonaceous particles proceeds via the formation of polycyclic aromatic hydrocarbons (PAH). 

Developing catalysis platforms for efficient chemical transformations requires either building upon useful empirical evidence or studying unexplored design spaces. Importantly, both approaches benefit from merging different research fields to solve new challenges. Here, I will discuss how materials design parameters can be applied to molecular electrocatalysts in the form of porous supramolecules to mimic confined enzyme/nanomaterial catalysis.

At the nanoscale, magnetic, optical, electronic, and thermal processes can differ drastically from their bulk counterparts. These deviations stem from reduced crystalline domains, large surface areas, and quantum confinement, leading to physical and chemical properties intricately dependent on size, morphology, and ligand identity as opposed to purely compositional structure.

Targeted design of electronic and magnetic properties in novel materials remains a critical bottleneck in the development of many next-generation electrical and electrochemical devices. In this talk, I will describe how the principles of molecular inorganic chemistry can be applied to systematically engineer materials hosting a diverse range of desired properties.

The transition to a sustainable future requires innovative approaches in materials design, utilization, and recycling. In this talk, I will discuss two advancements at the intersection of polymer chemistry and sustainability: the development of metal-chelating polymers for rare-earth element (REE: La–Lu, Y, and Sc) extraction, and the synthesis of chemically recyclable polymers.

The pursuit of next-generation materials to address the energy and sustainability crisis hinges on hybrid crystalline systems, particularly layered lattices with well-defined organic-inorganic interfaces. These materials harness the vast chemical space of organics and the superior electronic, photonic, or catalytic performance of inorganics, making the assembly tunable and solution processable.

Climate change and global air pollution are the world’s two most serious issues. Negative carbon and polluted air capture are critical strategies for addressing rising CO₂ and air pollution levels. State-of-the-art materials design at the atomic level is in high demand, and their fundamental mechanism must be revealed using cutting-edge microscopic and spectroscopic methodologies. As a result, the utilization of sustainable materials (e.g.

Semi-aromatic polyesters derived from petroleum are an important class of polymers that encompass a wide variety of thermal and mechanical properties. Unfortunately, replacing the aromatic component with cost-competitive bioderived monomers is an ongoing challenge. In this presentation, we describe the synthesis of nine different polyesters made from AB monomers that can be derived from lignin, and include full characterization of their thermal, mechanical, and rheological properties.

The second harmonic generation (SHG) is a nonlinear coherent second-order scattering process that causes frequency doubling of incident light. It is widely used in laser technology, spectroscopy, microscopy, wireless communication technology and fiber-optic communication systems. The main requirement for the SHG process is the noncentrosymmetry of the material, since the second-order susceptibility coefficient, which is responsible for the second harmonic generation, is zero in all centrosymmetric structures.
