Abstract: The invention relates to an acoustic phase mask, the phase mask having a variation in the acoustic index n, characterized in that the phase mask comprises a body comprising: at least one matrix formed from a deformable solid material, having a shear modulus of less than 10 MPa, and pores formed in the matrix, the pores being mostly filled with gas, the deformable solid material extending between the pores, the body having a porosity ? less than or equal to 50%, and a controlled porosity ? gradient resulting in a variation of the acoustic index n spatially in the body.

Abstract: Disclosed herein, are compositions, methods, and kits comprising engineered reverse transcription enzymes that exhibit several desired properties such as thermal stability, processive reverse transcription, non-templated base addition, and template switching ability. The engineered reverse transcription enzymes described herein demonstrate unexpectedly higher resistance to cell lysate inhibition, greater ability to capture full-length mRNA transcripts, and demonstrate improved results in small reaction volumes as compared to other engineered reverse transcription enzymes.

Abstract: The invention concerns a method whereby: (E1) an inner liquid phase is made to flow in an inner flow member, and an outer liquid phase in an outer flow member, the flow of the inner liquid phase opening within the flow of the second liquid phase; and the temperature and pressure in the contact area between the first and second liquid phases being such that the first and/or second liquid phase is in the supercritical state, (E2) the flow rate of the inner phase and/or outer phase is varied in such a way as to modify the flow profile, and a torque is identified from values of the flow rates of the inner and outer phases, called transition flow rates, from which the modification in the flow profile occurs (from drops to a jet; or from a jet to drops); (E3) from the transition torque identified in step (E2), the value of the interfacial tension between the two inner and outer liquid phases is calculated, or the result obtained is compared to that obtained for another torque in the conditions of steps (E1) and (E2

Abstract: The use of supercritical fluids in the production of particles in microfluidic systems is generally described. Small particles with narrow particle size distributions are useful in a wide range of applications. Submicron and micron-sized organic particles may exhibit enhanced properties such as, for example, increased dissolution rates, enhanced pharmaceutical efficacy, and ease of suspension in a carrier medium. Small organic particles may be particularly useful in drug delivery, exhibiting enhanced performance as inhalation aerosols, injectable suspensions, controlled release dosage drugs, transdermally delivered drugs, and the like. Supercritical fluids exhibit unique transport properties such as the ability to simultaneously diffuse through solids (e.g., like a gas) and dissolve materials (e.g., like a liquid).

Abstract: A re-terminable, no-crimp ST-type optical connector assembly includes a spring-loaded ferrule holder assembly and a reusable activation system for termination of the assembly. The optical connector can be terminated by a suitable cam activation tool. The connector includes a housing, such as a bayonet, matable to a mating adapter, a backbone retained within a rear of the housing, a ferrule holder provided within the backbone, and a cam provided between the ferrule holder and the backbone. The ferrule holder includes an alignment key exposed to mate with a cam activation tool to lock rotation of the ferrule holder relative to other connector components. The cam includes a cam activation cutout at a front face thereof that mates with a cam activation tool interface to enable rotation of the cam between de-activated and activated positions, the cam activation cutout also receiving the alignment key of the ferrule holder therethrough.

Abstract: An improved, reversibly terminable fiber stub connector assembly is provided that can be readily and positively terminated in the field using simple termination tools. This allows repositioning or replacement of fiber optic cable field fibers if termination is not acceptable in performance. The tool may be a hand-held tool, or used in conjunction with a connector support structure to provide simplified and expeditious field termination of fiber optic cables. The cam tool can include a throughbore that enables connection of a patchcord to the stub fiber of the connector during or shortly after termination without removal of the termination tool. Accordingly, field testing of the connection can be made at the site of termination.

Abstract: A tool for field terminating optical fibers has an optical fiber cable preparation area for cutting and stripping the optical fiber cables and includes a fiber optic plug termination area and a fiber optic jack termination area.
