Nanoparticle Surface Tension Energy Storage:
Using Laser-induced Second Harmonic Generation
for Energy Characterization and
Controlled Energy Release
In collaboration with Moscow State University, Laboratory of Nonlinear Optics of
Nanostructures and Photonic Crystals (Physics Department, www.shg.ru), BTG
researches the use of nanoparticle structures as an
energy-storage/energy-delivery system for Civilian and Defense applications.
Nanoparticle dispersed materials offer a very high potential to store energy in
the form of Surface Tension Energy (STE) with energy density comparable to
conventional chemical systems. Just as Chemical Energy stored in conventional
fuel and explosives, nano-particles energy storage is mobile and stable. At the
same time, it offers significantly more safety and control than the chemical
energy storage systems.
The particular focus of this research is the design of the laser-based systems
for release and characterization of STE from nanostructure materials using Second
Harmonic Generation. One of the most interesting classes of
nanoparticle-dispersed materials, for this purpose, is the arrays of metal
nanoparticles. Metal nanoparticle materials allow storing as much surface energy
as others nanoparticles and are unique in terms of laser induced release of
energy due to existence of local plasmon resonances.
The direct relation between STE and nonlinear optical
parameters of nanoparticles allows to very efficiently use the second order
harmonic generation to probe STE.

June 22, 2006
Brookhaven Technology Group, Inc., was awarded a new Phase I SBIR grant to develop an advanced surface plasma source for reliable long time production of H¯/D¯ beams with high brightness and high pulsed current and average intensity up to ~20mA. The principal goal of this project is to develop a high performance, long lifetime surface plasma H¯ source by using a unique new highly efficient helicon discharge plasma generator. The plasma flux formed by this helicon discharge will be used for surface plasma generation of H¯.
In Phase I, simulations of plasma generation, ion/atom conversion, and H¯/D¯ surface-plasma generation will be carried out to prove the feasibility of this new approach. The discharge system will be studied, beam extraction and formation including electron suppression will be designed, and computer simulated.
This is the third Phase I SBIR awarded to BTG for development of negative ion source technology. In previous years the company received Phase I and Phase II funding to design, build, and test a high brightness, long lived source of heavy negative ions (HNIS). This source is now available for commercialization. More information about the HNIS is available on this website.
