Abstract: Described herein is a method of preparing glass structures having tunable material properties. By varying process conditions, physical, thermal, optical, electrical, and mechanical properties of the glass particles can be altered in a predictable manner. By varying porosity, density, and pore structures, for example, a wide range of physical, thermal, optical, electrical, and mechanical characteristics of micron and nanometer sized glass particles can be achieved and/or modified.

Abstract: Glass microparticles and/or glass nanoparticles have been developed for use as: reflective paints; abrasive papers/wheels; flame retardant paints; thermal insulation for aggregates, self-cleaning building materials, absorbent of oils, diesel, gasoline, brake fluids, transmission fluids, ethanol, methanol, and acetone; cosmetics (lipstick, foundation, etc.), medicated dental implant, and targeted drug delivery systems.

Abstract: The present invention is a golf club (30) having a club head main body (34) with a recess (38), an polymer insert (40) in the recess (38), an isolation layer (52) and a weight body (50). The polymer insert (40) is composed of a thermosetting polyurethane material having a Shore D hardness in the range of 42 to 55, and a Bayshore rebound in the range of 51 to 60. The preferred thermosetting polyurethane material is formed from a p-phenylene diisocyanate prepolymer and a curing agent. The golf club (30) is preferably a putter, however, it may be a wood or an iron. The particular thermosetting polyurethane provides a soft striking face for feel and a good rebound for distance. The weight body (50) is preferably composed of a tungsten alloy, and the isolation layer (52) is preferably composed of a thermoplastic polyurethane.

Abstract: A bimetallic golf club head having a weight body for lowering the center of gravity of the golf club head in order to increase vertical gear effect upon impact with a golf ball, while also providing for an isolation layer between the golf club head's weight body and a main body portion comprising a ball striking front section. One purpose of the isolation layer is to isolate, or reduce the combination of, the impact vibration frequency pattern of the main body and the vibration frequency pattern of the weight body, thereby preserving the desirable feel and playability of a single metal golf club head while enjoying the improved performance of a low center of gravity golf club head. Another purpose of the isolation layer is to minimize or reduce the galvanic/intermetallic reaction between two different metallic materials that are placed in direct contact.

Abstract: An electric discharge gas laser having a laser cavity in which is contained a laser gas and a fan for circulating the laser gas. The fan is supported by an active magnetic bearing system and driven by a brushless DC motor in which the rotor of the motor and at least two magnetic bearings sealed within the gas environment of the laser cavity and the motor stator and the coils of the bearing magnets are located outside the gas environment.
