| 20080207801 | Compatibilization of Polymer Clay Nanocomposites - A polymer nanocomposite contains layered clay dispersed in a polymer matrix together with compatibilizers for the clay and polymer matrix. The compatibilizers are a combination of two or more graft polymers. One graft polymer has high functionality and short chain length and another graft polymer has low functionality and long chain length. Such polymer nanocomposites have improved dispersion and better strength and modulus, while maintaining good toughness and impact strength. The polymer nanocomposites are particularly useful in applications where good mechanical performance and light-weight are of importance. | 08-28-2008 |
| 20090177282 | IMPLANTABLE BIOMIMETIC PROSTHETIC BONE - Bone tissue at the interface of a bone implant is shielded from stresses found in normal bone because of the higher stiffness or rigidity in the implant versus in bone. The resulting “stress shielding” of the bone by the implant eventually results in resorption of bone at the bone-implant interface and ultimately necessitates replacement of the bone implant. To overcome these problems, an implantable biomimetic prosthetic bone having a porous surface, a fiber-reinforced composite structure, and a polymer-based core is disclosed. The prosthetic bone is a good match for structure, stiffness, viscoelastic properties, specific weight and overall structure as real bone or host tissues adjacent to the prosthetic bone. The prosthetic bone may be formed as a total hip prosthesis. | 07-09-2009 |
| 20100044914 | Primer composition and uses thereof - The present invention provides a primer for a thermoplastic and/or elastomeric substrate, the primer comprising a film of an epoxy-modified polymer selected from the group consisting of an epoxy-modified-thermoplastic polymer, an epoxy-modified-thermoplastic polymeric composite, an epoxy-modified-elastomeric polymer, an epoxy-modified-elastomeric polymeric composite, a blend thereof, and any mixture thereof. Also provided are methods of repairing, inserting, assembling and coating a thermoplastic or elastomeric substrate using the primer of the present invention. | 02-25-2010 |

| 20080302357 | Solar photovoltaic collector hybrid - The present invention discloses a system for a hybrid solar energy collector comprising a CIGS photovoltaic energy collector, the photovoltaic energy collector being thermally coupled to an energy absorbing working fluid casing for flowing heat out to heat sink The solar radiation is trapped in the photovoltaic collector, generating electrical power from the CIGS photovoltaic array, The array is cooled by the working fluid transferring unproductive heat away from the photovoltaic array and into an exterior heat sink via the cooling fluid circuit, thus making the photovoltaic array more efficient, while adding another energy source. Where thermal collection is not beneficial, a floating platform supported CIGS PV array may be cost effectively cooled to increase efficiency, by harnessing wave energy from a wave power device to flow cooling or evaporative spray water over the panel. | 12-11-2008 |
| 20090065046 | Solar photovoltaic module to solar collector hybrid retrofit - The present invention discloses a system for a retrofitting a photovoltaic energy collector, by coupling a thermal energy absorbing working fluid casing for flowing heat out to a heat sink The solar module is cooled by the working fluid transferring unproductive heat away from the photovoltaic array and into an exterior heat sink via the cooling fluid circuit, thus making the photovoltaic array more efficient, while adding another energy source. The retrofitting can be done at the consumers convenience, discretion and site, overcoming the current requirement forcing the consumer to decide on one solar technology over another with competing needs. | 03-12-2009 |
