Nonequilibrium Plasma-Liquid Interaction

The interaction of plasma with liquids represent a research frontier involving challenges in the understanding of multi-phase physical and chemical kinetics, interface transport, surface phenomena, and self-organization. Plasma-on-liquid interactions are at the core of diverse established and novel applications in materials and chemical synthesis, environmental remediation, bioengineering, and medicine.

Turbulence in Nonequilibrium Plasmas

Fundamental understanding is being sought of the dynamics between turbulent dissipation and kinetic relaxation processes in nonequilibrium plasmas. The large range of scales typically involved in turbulent flow phenomena combined to the intrinsic nonlinear and multiphysics nature of nonequilibrium plasmas has prevented a clear of plasma turbulence in a wide variety of natural phenomena and technological applications, ranging from solar dynamics and aurorae to plasma-enhaced combustion and plasma synthesis of materials.

Nonequilibrium Plasma-Based Recycling of Carbon Dioxide

The reliance of plasma sources on electric energy makes them ideal for the recycling of carbon dioxide from hydrocarbon-based energy generation into more valuable resources. Key for the success of plasma-based carbon recycling are high energy and conversion efficiencies, simplicity of operation and infrastructure, and handling of large volumetric rates of undiluted carbon dioxide. Nonequilibrium atmospheric pressure plasma sources are suitable candidates for fulfilling those requirements.

Concentrating Solar Power Photo-Thermo-Chemical Synthesis

Concentrating solar power is investigated for the operation of photo-thermo-chemical reactors for the synthesis of energy carrier and storage fluids, i.e. Solar Fuels, from carbon dioxide, water, and/or methane. The success of such reactors would lead to effective carbon sequestration within hydrocarbon-based energy utilization.

Advanced Plasma & Laser Materials Processing

Plasma and laser processing of materials offer unique advantages that range from compact installations to rapid throughput and flexibility. The complexity of the interplay among fluid dynamic, thermal, chemical, radiative, and electromagnetic processes hinders the further development of these processes. Research is being sought to construct comprehensive modeling and simulation approaches for the fundamental understanding of these processes that would lead more effective and sustainable materials processing.
