Research

Resonance-enhanced PETE
The energy converter with resonance-enhanced photon-enhanced thermionic emission is a device producing electric power from heat and photon. Several approaches are studied for achieving the highly efficient device.
Coming soon CO2 conversion
Development of plasma process with CO2 as a raw material.
Laser ablation in high-pressure fluid environemnts
Medium pressure can be a new parameter to control properties of produced nanoparticles.
Plasma-liquid interface
One of the important keys controlling the plasma processing with liquid.

Plasma-assisted biological macromolecular crystallization
Novel crystallization method of biological macromelecules with low-temperature atmospheric-pressure plasmas.
Plasma-assisted chemical fluid deposition (P-CFD)
Material synthesis with plasma in very dense environments, such as supercritical fluid environments, for high-speed and high-quality processing.
Currently, nanomaterials syntheses with this novel processing environment are in progress.

Ball lightning
Ball lightning is still an unsolved problem in atmospheric physics. We are studying a luminous ball created from Si.

High-pressure discharge dynamics with electric field measurements
Electric field induced coherent Raman scattering is one of the most promising methods for E-field measurements in high pressure environments.
Neutral energy distributions in glow discharges
Not only ions, but also neutrals can be energetic in glow discharges, especially in the cathode fall region at collisional conditions. We have measured and analyzed the distributions striking on the cathode surface. Energy flux caused by the energetic neutrals might be important in various applications.
Low-temperature glow-like discharge generations with three electrodes
This generation method allows us to generate (relatively) large-volume glow-like discharge in high-pressure environments, including an open air environment.
Magnetized microdischarge plasma in low pressure environments
By applying strong magnetic field (~1 T), microdischarges can be generated even in very low pressure environments (against the normal Pd law). Very clear drift waves are observed in such discharges.
Micro thruster
This is one possible application of the MMP. The picture (left: micro Hall effect thruster) was taken at Cappelli group (Stanford university).
