A plasma 10 is generated within a film formation chamber 2, and mainly a nitrogen gas 11 is excited within the film formation chamber 2. Then, the excited nitrogen gas 11 is reacted with a diborane gas 13 diluted with a hydrogen gas, thereby forming a boron nitride film 15 on a substrate 4. Thus, the boron nitride film 15 excellent in mechanical and chemical resistance, high in thermal conductivity, and having a low relative dielectric constant κ can be formed speedily.

Compositions and methods are provided for producing a medical device such as a stent, a stent graft, a synthetic vascular graft, heart valves, coated with a biocompatible matrix which incorporates antibodies, antibody fragments, or small molecules, which recognize, bind to and / or interact with a progenitor cell surface antigen to immobilize the cells at the surface of the device. The coating on the device can also contain a compound or growth factor for promoting the progenitor endothelial cell to accelerate adherence, growth and differentiation of the bound cells into mature and functional endothelial cells on the surface of the device to prevent intimal hyperplasia. Methods for preparing such medical devices, compositions, and methods for treating a mammal with vascular disease such as restenosis, artherosclerosis or other types of vessel obstructions are disclosed.

This invention relates to novel room-temperature process for obtaining calcium phosphate, in particular hydroxyapatite, coatings and microspheres that encapsulate drugs, proteins, genes, DNA for therapeutical use. The coatings and microspheres are designed to perform a defined biological function related to drug delivery, such as gene therapy through gene delivery. A novel method for encapsulation, and subsequent controlled release of therapeutically active agents from such biofunctional coatings and microspheres is disclosed. Such coatings and microspheres are useful for side-effects free, long-term, targeted, controlled release and delivery of drugs, proteins, DNA, and other therapeutic agents.

The invention discloses a method for treatment and in-situ ecological restoration of a black and stink riverway by using microorganism. The invention is characterized in that target strains with pertinence are selected from sewage and then matched and combined with the existing strains to form compound microbial agents; and the sewage in the riverway is treated by using the matched compound microbial agents. In the invention, according to the specific pollution conditions of the riverway, the selected strains which are grown in the sewage are used to treat the sewage in the riverway, and the strains are matched and combined with the existing strains aiming at the pollution conditions of the water body in the riverway, so that the strains can exert synergistic effects in a microorganism sewage treatment system, thereby rapidly forming superior floras so as to decompose, absorb and transfer pollutants in the riverway and then achieving the optimum treatment efficiency. In the invention, the microorganism is firstly used to treat the water body, and then the water body is treated through the self-cleaning capability of the water body, thereby reaching the purpose of curing the exterior and the inherence and not generating secondary pollution. The method has the characteristics of safety, high efficiency, low cost, small investment and the like, and is simple to operate.

A microencapsulated product comprises a core, a first shell comprising a protein and being substantially carbohydrate-free, and a second shell comprising a carbohydrate and being substantially protein-free. The double shell structure provides a strong shell that makes the microcapsule suitable for use in food products. The core can be a lipid, and in particular a structured lipid with nutritional benefits, such that the nutritional benefits can be passed on to the consumer. The microcapsules of the present invention can be used in making foods products, beverage products, and mixes for making such food and beverage products.

The invention discloses a construction method for spraying-seeding kind-loam matrix on a side slope. The construction method comprises steps of A) analyzing stability of the side slope and reinforcing the side slope, B) eliminating dangers for the side slope, C) hanging a net for a slope surface of the side slope and constructing anchor rods, D) arranging a river system for the side slope and arranging a drainage system on the side slope, E) spraying and seeding seeds on the side slope via a kind-loam matrix spraying-seeding way, and F) conducting side slope maintenance management work including covering a non-woven fabric, watering, applying fertilizer, preventing diseases and insects, supplementing seeds and post-monitoring. Two-layered spraying-seeding way is applied; through bionic operation, kind-loam matrix in the nature suitable for the side slope can be simulated; plant seed germination, root development, microorganism activity and nutrient conversion can be facilitated; plant growth development can be promoted; and great application prospect can be achieved.

The present invention provides an injector-ignition fuel injection system for an internal combustion engine, comprising an ECU controlling a heated catalyzed fuel injector for heating and catalyzing a next fuel charge, wherein the ECU uses a one firing cycle look-ahead algorithm for controlling fuel injection. The ECU may further incorporate a look-up table, auto-tuning functions and heuristics to compensate for the rapid rotational de-acceleration that occurs near top dead center in lightweight small ultra-high compression engines as may be used with this invention. The ECU may further ramp heat input to the injector in response to engine acceleration requests and, under such circumstances, may extend its look-ahead for up to four firing cycles.

The present invention provides a heated catalyzed fuel injector that dispenses fuel substantially exclusively during the power stroke of an internal combustion engine, wherein ignition occurs in a fast burn zone at high fuel density such that a leading surface of the fuel is completely burned within several microseconds. In operation, the fuel injector precisely meters instantly igniting fuel at a predetermined crank angle for optimal power stroke production. Specifically, the fuel is metered into the fuel injector, such that the fuel injector heats, vaporizes, compresses and mildly oxidizes the fuel, and then dispenses the fuel as a relatively low pressure gas column into a combustion chamber of the engine.

A bone or dental implant material in the form of a paste includes a mixture of calcium phosphate and / or calcium-containing powders and a solution that is (1) an acidic calcium phosphate solution saturated with respect to one or more calcium phosphate compounds, (2) a concentrated acid solution, or (3) salt solutions with a cationic component other than calcium. The paste is stable, resistant to washout and will form hydroxyapatite and harden relatively rapidly to a cement.
