Typically, electron beam radiation therapy aims at delivering a uniform dose to a target volume containing cancer cells. Electron sources typically impinge a spatially uniform flux across the beam onto the patient; however, irregular patient and bolus surfaces, the latter encountered in bolus electron conformal therapy (ECT), scatter electrons unevenly creating non-homogeneous dose distributions in the target. However, spatially-modulated beam intensities can restore target dose homogeneity, as well as enable utilization of other advanced ECT methods. Unfortunately, present methods, which have attempted to spatially-modulate beam intensities, have been either impractical or ineffective. Here, a novel, passive method has been developed to spatially-modulate electron beam intensities by taking advantage of multiple Coulomb scattering. The method utilizes Island Blocks or Island Apertures, strategically located in 'transparent' or 'opaque' substrates, respectively, which are placed in the beam's path. This method spatially-modulates electron flux across the beam with insignificant loss of electron beam energy. Thus, delivering a uniform, highly conformal dose distribution to the target volume is possible. Further, the method is inexpensive and can be easily incorporated into existing electron therapy machines.

Passive radiotherapy intensity modulator for electrons

A gaseous p-xylylene monomer, formed by reacting xylene with a monatomic oxygen source, is mixed with a functional gaseous monomer. The resulting mixture may be deposited and solidified on a substrate, which may optionally be exposed to a photoinitiating light energy and/or a permittivity enhancing electric or magnetic field. Alternatively, the resulting gaseous mixture may be trapped and condensed in a condenser, which may contain a solvent to facilitate trapping. The condensate may be mixed with a tertiary substance, e.g., another monomer, a reactive substance or an inert material.

Embodiments of a high-permittivity, low-leakage energy storage device, such as a capacitor, and methods of making the energy storage device are disclosed. The disclosed device includes electrically conductive first and second electrodes, and a sterically constrained dielectric film disposed between the first and second electrodes. The sterically constrained dielectric film comprises a plurality of polymeric molecules, and at least some of the polymeric molecules are bound to the first electrode. The disclosed device may include an insulative layer between the first electrode and the dielectric film and/or between the second electrode and the dielectric film.

Energy storage device

A solid state electrical energy state storage device includes multiple dielectric layers or an integral heterogeneous dielectric layer. Layers or portions of the heterogeneous layer have permittivity augmented by exposing the dielectric material to electric/magnetic fields during formation of the dielectric before complete solidification. Such exposure results in radicals and/or an ordered matrix. A dielectric for the device may contain a new xylene based polymer formed under atmospheric conditions via reaction with monatomic oxygen and provided an augmented permittivity through exposure of the polymer to a magnetic field and/or an electric field during condensation and solidification on a substrate.

High energy density electrostatic capacitor

An energy storage device comprises a capacitor having a dielectric between opposite electrodes and a nonconductive coating between at least one electrode and the dielectric. The nonconductive coating allows for much higher voltages to be employed than in traditional EDLCs, which significantly increases energy stored in the capacitor. Viscosity of the dielectric material may be increased or decreased in a controlled manner, such as in response to an applied external stimulus, to control discharge and storage for extended periods of time.

Methods are disclosed for creating extremely high permittivity dielectric materials for use in capacitors and energy storage devices. High permittivity materials suspended in an organic non-conductive media matrix with enhanced properties and methods for making the same are disclosed. Organic polymers, shellac, silicone oil, and/or zein formulations are utilized to produce thin film low conductivity dielectric coatings. Transition metal salts as salt or oxide matrices are formed at low temperatures utilizing mild reducing agents.
