Abstract:
Photoimagable polymers, as well as dielectric materials and their manufacture and use in the production of printed circuit boards and printed wiring boards are described. The polymers comprise between about 30 and about 70 parts of a polyfunctional resin and between about 70 and about 30 parts of the condensation product of an epihalohydrin and a bisphenol based on 100 parts by weight of resin. The polymer is cured by a photocationic initiator. It is characterized by a glass transition temperature of at least about 140° C. and a flex fatigue life of at least about 10,000 cycles at a 3% strain. Optionally, less than 10 parts of a third specified epoxy resin may be added to the mixture to improve flexibility without decreasing the glass transition temperature of the polymer.
Abstract:
The present invention relates to self-assembly of a photosensitiser on a nanoparticle. The invention also provides methods for production of functionalised (eg. stabilised) nanoparticles. The nanoparticles may be used in Photodynamic Therapy (PDT). The invention can provide, for example, self-assembled phthalocyanine monolayers (SAMs), wherein the monolayer is formed on a metallic nanoparticle. The term “metallic” as used herein refers to metals, metal oxides and other metal-containing compositions. According to the invention a functionalised nanoparticle comprises: a metallic core; a photosensitiser monolayer chemically bonded to said core, said monolayer containing molecules capable of photo-excitation to produce a reactive oxygen species such as singlet oxygen, from oxygen molecules; and a phase transfer reagent.

In accordance with some embodiments of the present invention, the microcapsules contain a phase change material.
Abstract:
A composition for use in the treatment of lesions of the human or animal body comprises xanthine oxidoreductase and a pharmaceutically acceptable electron donor system. The composition can accelerate wound healing, especially in a hypoxic environment.
Abstract:
A method for controlling an engine having both an electronically controlled inlet device, such as an electronic throttle unite, and an electronically controlled outlet device, such as a variable cam timing system is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by coordination of the inlet and outlet device. This improved control is used to improve various engine control functions.
Abstract:
A cathode ray tube comprises a display and a funnel envelope. The funnel envelope comprises a thixotropic material. The thixotropic material thixotropic material is selected from at least one of thixotropic magnesium, thixotropic magnesium alloys, thixotropic aluminum, thixotropic aluminum alloys, or mixtures thereof or combinations.
Abstract:
A method for controlling an engine having at least one cylinder is provided. The engine includes an intake manifold and an outlet control device for controlling flow from the intake manifold into the cylinder. The method includes generating an operator command. The method further includes controlling flow into the cylinder by changing the outlet control device to control flow into the cylinder based on the operator command.
Abstract:
A method for controlling cycling of an air conditioning compressor coupled to an internal combustion engine interrupts normal cycling based on operation conditions. In addition, normal engaged and disengaged cycling durations are adaptively estimated in real-time. The method of the present invention achieves improved fuel economy and improved drive feel. As an example, improved fuel economy is achieved by engaging the compressor during braking or when the engine is being driven by the vehicle. As another example, improved drive feel is achieved by engaging the compressor during transient conditions when drive feel is unaffected.
Abstract:
A method for controlling reductant added to an exhaust of an engine having a lean NOx catalyst and a particulate filter adjusts a reductant amount during particulate filter regeneration. The method adjusts the reductant amount to account for reducing agents released from the particulate filter that are experienced by the lean NOx catalyst. In addition, management of particulate filter regeneration is based on both an estimated amount of stored particles and conditions of the lean NOx catalyst. In this way, operation of both the particulate filter and the lean NOx catalyst can be optimized. Also, termination of particulate filter regeneration is determined based on operating conditions.
