Publication number: 20100213643Abstract: A simple and direct methodology for synthesis of polycrystalline silicon sheets is demonstrated in our invention, where silica (SiO2) and elemental carbon (C) are reacted under RF or MW excitation. These polycrystalline silicon sheets can be directly used as feedstock/substrates for low cost photovoltaic solar cell fabrication. Other techniques, such as textured polycrystalline silicon substrate formation, in situ doping, and in situ formation of p-n junctions, are described, which make use of processing equipments and scheme setups of various embodiments of the invention.Type: ApplicationFiled: February 25, 2010Publication date: August 26, 2010Inventors: Prasad N.

Patent number: 7767159Abstract: A centrifugal pump adapted to excite a high-intensity sound wave in a fluid feedstock is disclosed. The impeller and stator of the pump are provided with multiple apertures sized and spaced to produce a sound wave of an intensity greater than one megawatt per square meter in the fluid. The sound wave forms cavitation bubbles in the fluid, and the static pressure in the pump combines with the compression cycle of the sound wave to collapse the bubbles at a rate sufficient to cause exothermic reactions in the fluid. The sonic reactor can be configured for use to produce thermal energy, oil refining, catalyst production, water desalination and other uses.Type: GrantFiled: March 29, 2007Date of Patent: August 3, 2010Inventor: Victor Nikolaevich Glotov

Publication number: 20100178212Abstract: An action on liquids by the energy of a cavitation acoustic field, which is generated by ultrasonic frequency elastic oscillations of a liquid, in such a way that athermodynamic disequilibrium state is formed in the liquids. Such a mechanism for transmitting energy to a liquid is an epithermal mechanism and produces therein the process which is inherent to high-energy physics and chemistry. It makes it possible, for example, to accumulate a certain quantity of energy in water by destroying the internal structure thereof formed by hydrogen bonds of individual molecules therebetween, practically without heating it and afterwards, to release the energy in the form of a hydration heat, while the water recovers the equilibrium state thereof or interacts with other substance. The cavitation reactor of this invention includes a harmonic oscillation source in the form of equifrequential resonators in which liquid oscillations produce elastic stationary waves.Type: ApplicationFiled: April 19, 2006Publication date: July 15, 2010Inventor: Sergei Dmitrievich Shestakov

Patent number: 7695672Abstract: A method and an apparatus in form of a disinfecting apparatus comprising a steam device for combating germs on the surface of products, in particular of food products. The apparatus employs a combination of steam and ultrasound to kill germs on the surface of a product which is conveyed past the steam device. Pressurized steam is fed through a steam passage to an opening conveying the steam to a cavity, in which the steam is made to oscillate at a ultrasonic frequency. The oscillations in the steam prevent the steam from heating the products excessively, while germs presents on the surface of the products are heated and killed.Type: GrantFiled: March 27, 2002Date of Patent: April 13, 2010Assignee: Force TechnologyInventor: Niels Krebs
