摘要:
The present invention provides a series of new and improved compounds/materials as vehicles to delivery degradative enzymes to remove/remedy environmental pollutants. The inventive material comprises a series of amide-functionalized ordered mesoporous carbon (AFOMC), which utilizes chemical conjugation techniques for the tethering of enzymes to the surface of the synthesized AFOMC. The delivery mechanism may be utilized to express a wide variety of toxin-degrading enzymes for removal/remediation of organic pollutants.

Phthalocyanine pigments having 0-4 chlorine atoms have a narrow particle-size range with 90% of particles between about 0.01-0.10 μm, the average particle size of no more than about 0.5 μm, a D99 of no more than about 0.3 μm, and a polydispersity of about 2.0 or less. Pigment compositions contain the phthalocyanine pigment and water-based dispersing resin. The pigments and the compositions are compatible with waterborne coating systems, exhibit an excellent metallic down travel, and are especially useful for the automotive painting applications.

A cryopump provides for high pumping speed of Type III gases. An open configuration of a frontal array provides high conductance of gases into a radiation shield which is shaped to focus gases toward a second stage array. The second stage array has an open configuration of baffles coated with adsorbent. Substantially all of the adsorbent has a direct line of sight to the radiation shield or to the opening in the radiation shield, and substantially all of the baffles are coated with adsorbent. In one form, the second stage cryopump array comprises an array of discs fanned to define a generally ball shaped envelope.
摘要:
An electronic module includes a substrate, at least one surface mounted integrated circuit (IC) component and an underfill material. The substrate includes a plurality of electrically conductive traces, formed on at least one surface of the substrate, and the component is electrically coupled to at least one of the conductive traces. The underfill material is positioned between the component and the substrate and provides at least one pedestal that supports the component during encapsulation. The underfill material, when cured, maintains the integrity of the electrical connections between the component and the conductive traces.

Methods and systems for usage-based product definition are disclosed. In one embodiment, a method includes instancing one or more usage-based product definition inputs, and assessing at least one of an applicability expression, an engineering requirement, and a manufacturing availability expression. The method further includes generating the product definition based on at least some of the usage-based product definition inputs, applicability expressions, engineering requirements, and manufacturing availabilities. In alternate embodiments, the instancing may include transforming a coordinate system of a component from a component-centered coordinate system to a product-centered coordinate system.

A seal assembly adapted for use in conjunction with a trocar assembly includes a seal body permitting the selective insertion and removal of instruments. The seal body includes a plurality of overlapping seal segments, each seal segment including a peripheral edge with a central seal member extending therefrom. The central seal member includes a free edge remote from the peripheral edge. A reinforcement pad is located on at least one of the seal segments between the peripheral edge and the free edge of the central seal member.

The present invention is directed to compositions and methods related to delivering degradative enzymes to remove/remedy environmental pollutants. The inventive material comprises a series of amide-functionalized ordered mesoporous carbon (AFOMC), which utilizes chemical conjugation techniques for the tethering of enzymes to the surface of the synthesized AFOMC. The delivery mechanism may be utilized to express a wide variety of toxin-degrading enzymes for removal/remediation of organic pollutants.
摘要:
2,5-di(p-methoxyanilino)terephthalic acid crystal types I and II are made by controlling the pH during the recovery of the oxidized product of the condensation of dimethylsuccinyl succinate with p-methoxyaniline. The resulting 2,5-di(p-methoxyanilino)-terephthalic acid can be converted into 2,9-dimethoxyquinacridone or a solid solution thereof having controlled characteristics.

In certain embodiments, a system and method for insurance premium payment is provided that automatically charges recurring insurance premiums to a credit or debit card chosen by the consumer. The system may apply a reward component and a special interest rate component to the charged premium so that card holders and their insurance companies share in the financial benefits of card usage.
摘要:
Crude indanthrone is milled, with or without other additives, to reduce and normalize particle size and distribution to a sub-pigmentary, near amorphous, state. The resulting highly aggregated crude powder is then treated with a heterogeneous solvent system of water and an alkyl ester of an aromatic carboxylic acid, such as methyl benzoate, to de-aggregate and grow the particles back to a pigmentary size. The conditions of the solvent treatment can be controlled with respect to temperature, time, and solvent ratio such that the desired properties of strength, shade, and dispersability are optimized.
