摘要:
The present disclosure provides a method of forming a hermetically sealed enclosure that comprises a diamond material. The method comprises providing first and second enclosure components comprising the diamond material and having first and second recesses, respectively, at edge portions. At least one of the first and second enclosure components has a cavity. The enclosure components have respective contact surfaces at the first and second recesses and are shaped such that an outer channel is formed by the co-operation of the first and second recesses when the first and second enclosure components are contacted at the contact surfaces to form the enclosure. The method further comprises bonding a first type of material to at least surface portions of the first and second recesses of the first and second enclosure components, respectively. The method also comprises bonding a second type of material to the first type of material so that the second type of material covers at least portions of the first type of material. The second type of material is biocompatible and suitable for forming a hermetically sealed seal. In addition, the method comprises contacting the enclosure components to form the enclosure and bonding the second type of material of the first enclosure component to the second type of material of the second enclosure component so as to form a hermetically sealed seal in the outer channel.
摘要:
The present invention relates generally to the task of automatically counting the fission track density in a prepared crystal. Two images are captured by a charged coupled device (CCD) (16) attached to a microscope (14). The first or reflected light image (18) is of the surface of the crystal (12), the light captured by the CCD (16) having been reflected from the crystal surface. The reflected light image (18) is a RGB image of a prepared crystal of mica (12) containing surface voids corresponding to etched fission tracks. The second or transmitted light image (24) is of a plane near the surface of the crystal (12). The transmitted lighting image (24) is generally the same view as the reflected light image (18). A fission track void can be detected by comparing the reflected light (18) and the transmitted light (24) images. This comparison of the reflected light and the transmitted light images is best achieved using a computer software program, although this can also be done by a person comparing the images side by side or visually superimposing one on top of the other.
摘要:
The invention provides novel reagents and methodologies for detecting free versus bound compounds. It is particularly useful to detect thrombin when it is not bound to A2M in the presence of thrombin bound to A2M by using a modified substrate that is sterically hindered from reacting with the bound thrombin.
摘要:
The present invention relates to a phosphopeptide-stabilized amorphous calcium phosphate and/or amorphous calcium fluoride phosphate complex, wherein the complex is formed at a pH of below 7.0. Methods of making such complexes are also provided. The complexes are useful in dental applications, in particular in dental remineralisation.
