Abstract:
A multi-well plate with wells having ultra-thin walls and yet with sufficient structural rigidity to allow reliable use of the plate in automated instrumentation is formed by first forming a plate blank by injection molding, the blank being of a thickness that provides the desired rigidity, and then subjecting the blank to vacuum forming to stretch designated areas in the blank to form wells or to extend wells already formed, the stretching resulting in a reduction in thickness of the molded resin at the walls of the wells only.
Abstract:
A technique is provided that utilizes one or both of a control line actuation mechanism and a connector protection mechanism for use in a wellbore environment. Upon landing a lower well assembly and an upper well assembly at a desired wellbore location, control line connectors are engaged. The control line actuation mechanism and/or connector protection mechanism facilitate the formation of a desirable control line connection.
Abstract:
Highly uniform silicon/germanium nanoparticles can be formed into stable dispersions with a desirable small secondary particle size. The silicon/germanium particles can be surface modified to form the dispersions. The silicon/germanium nanoparticles can be doped to change the particle properties. The dispersions can be printed as an ink for appropriate applications. The dispersions can be used to form selectively doped deposits of semiconductor materials such as for the formation of photovoltaic cells or for the formation of printed electronic circuits.
Abstract:
A sensor chip that includes: a fluorescence quenching surface; a nucleic acid probe that contains first and second ends with the first end bound to the fluorescence quenching surface, a first region, and a second region complementary to the first region, the nucleic acid probe having, under appropriate conditions, either a hairpin conformation with the first and second regions hybridized together or a non-hairpin conformation; and a first fluorophore bound to the second end of the first nucleic acid molecule. When the first nucleic acid molecule is in the hairpin conformation, the fluorescence quenching surface substantially quenches fluorescent emissions by the first fluorophore; and when the first nucleic acid molecule is in the non-hairpin conformation, fluorescent emissions by the fluorophore are substantially free of quenching by the fluorescence quenching surface. Methods of making the sensor chip, and their methods of use are also disclosed.

Highly uniform silica nanoparticles can be formed into stable dispersions with a desirable small secondary particle size. The silica particles can be surface modified to form the dispersions. The silica nanoparticles can be doped to change the particle properties and/or to provide dopant for subsequent transfer to other materials. The dispersions can be printed as an ink for appropriate applications. The dispersions can be used to selectively dope semiconductor materials such as for the formation of photovoltaic cells or for the formation of printed electronic circuits.

Abstract:
Desirable composites of polysiloxane polymers and inorganic nanoparticles can be formed based on the appropriate selection of the surface properties of the particles and the chemical properties of the polymer. High loadings of particles can be achieved with good dispersion through the polymer. The composites can have good optical properties. In some embodiments, the inorganic particles are substantially free of surface modification.
Abstract:
The present invention discloses a body fluid analyzing system, comprising: a central control and processing component for sending a control signal to the source image capturing component; a source image capturing component for capturing a body fluid source image according to said control signal and sending said source image to said central control and processing component. Said central control and processing component is further used for transforming source images to image coefficients and generating the corresponding coefficient matrix. Then the coefficient matrix is inversely transformed to a focus-fused image for output. The present invention further discloses an image processing device and method for analyzing body fluid. The application of the present invention can reduce the probability of object image omission or fuzziness and, to a great extent, increase the identification success rate so that the precision of the entire system is increased.
Abstract:
A completions system utilizing a unique hydraulic coupling. The system includes an upper completion stinger configured for coupling to a lower completion tubular. Both the stinger and the tubular are outfitted with hydraulic lines therethrough. Thus, as the stinger is coupled to the tubular, hydraulic lines are also coupled. However, the termination of each line is sealingly covered by a slidable sleeve in advance of attaining the coupling between the stinger and tubular. Therefore, the lines are protected from contamination during potentially significant periods of well deployment that may occur in advance of completed coupling and system installation. Furthermore, the manner of hydraulic coupling between the stinger and tubular reduces the likelihood of damage to the hydraulic lines during the installation process.
