Provided are electrokinetically-altered fluids (e.g., gas-enriched (e.g., oxygen-enriched) electrokinetic fluids) comprising an ionic aqueous solution of charge-stabilized gas-containing nanostructures in an amount sufficient to provide, upon contact with a cell, modulation of at least one of cellular membrane potential and cellular membrane conductivity. Further provided are the methods of making the electrokinetically-altered ionic aqueous fluid compositions. Particular aspects provide for regulating or modulating intracellular signal transduction associated by modulation of at least one of cellular membranes, membrane potential, membrane proteins such as membrane receptors, including but not limited to G-Protein Coupled Receptors (GPCR), and intercellular junctions (e.g., tight junctions, gap junctions, zona adherins and desmasomes). Other embodiments include particular methods of producing the electrokinetically-altered fluids. The electrokinetically-altered fluid compositions and methods of producing the fluid include electrokinetically-altered ionic aqueous fluids optionally in the form of solvated electrons stabilized, at least in part, with molecular gas (e.g., oxygen).

The invention provides a manufacturing method of dynamic pressure bearing, which comprises the following steps: an obturator is provided, the surface of the obturator is convexly provided with a plurality of protrusions; the obturator is arranged in the central position of a hollow bearing mould, and a hollow cavity in the bearing mould is filled with the mode of encapsulation molding to form an embryo of the dynamic pressure bearing; the obturator is removed from the embryo of the dynamic pressure bearing through the mode of catalytically degreasing; binder in the embryo of the dynamic pressure bearing is removed; the embryo of the dynamic pressure bearing is sintered; finally, the dynamic pressure bearing is formed. The dynamic pressure bearing integrally forms the dynamic pressure bearing and a dynamic pressure groove through the method of encapsulation molding, and removes micro-molecular gases which is decomposed from the obturator by using the method of catalytically degreasing, thereby preventing the embryo of dynamic pressure bearing from generating defects as deformation, bending or fracture, etc., improving the mass production capability and the dimensional precision of the dynamic pressure bearing. The invention also provides a manufacturing method of a dynamic pressure rotating shaft.

The invention relates to a microporous transition-group metal organic framework material, and preparation and application methods thereof.

A method and device are presented for producing an intensive flow of atoms from an input flow of a molecular gas. Effects of ignition of a gas discharge of a complex type and dissociation of the gas molecules by electron impact in a discharge cell are utilized. The flow of atoms is output from the discharge cell through at least one emitting aperture. The complex gas discharge is composed of a main discharge and two auxiliary discharges of different types ignited in substantially coinciding zones of the discharge cell. The main discharge is an arc Penning discharge ignited in the vicinity of at least one emitting aperture. The first auxiliary discharge is a magnetron discharge with heated cathode, and the second auxiliary discharge is either a Penning discharge, or a Penning discharge with hollow cathode. The dissociation of the gas molecules is thereby carried out in the complex discharge and results in creation of the flow of hot and thermally atoms.
