An energy storage device comprises a capacitor having a dielectric between opposite electrodes and a nonconductive coating between at least one electrode and the dielectric. The nonconductive coating allows for much higher voltages to be employed than in traditional EDLCs, which significantly increases energy stored in the capacitor. Viscosity of the dielectric material may be increased or decreased in a controlled manner, such as in response to an applied external stimulus, to control discharge and storage for extended periods of time.

A method and apparatus for determining a volume of a phase of a multiphase fluid flowing in a production tubular is provided. A magnetic field is imparted on the fluid to align nuclei of the multiphase fluid along a direction of the magnetic field. A radio frequency signal is transmitted into the multiphase fluid to excite the nuclei, and a signal is detected from the nuclei responsive to the transmitted radio frequency signal. An amplitude of the detected signal is determined and the volume of the phase flowing in the production tubular is determined using the determined amplitude and an amplitude of a calibration signal.

The invention relates to binder for construction and discloses a high-polymer instant-dissolving environment-friendly binder power. The high-polymer instant-dissolving environment-friendly binder powder is characterized by including, by weight percentage, 20-75% of cold water instantly-dissolving type polyvinyl alcohol powder, 0.5-15% of polyacrylamide and 15-70% of hydroxyethyl cellulose or hydroxypropyl methyl cellulose. During production, the above raw materials are mixed and stirred uniformly directly according to proportion and packaged to form the high-polymer instantly-dissolving environment-friendly binder powder. The high-polymer instantly-dissolving environment-friendly binder powder has the advantages of low cost, environment protection, quick dissolving by cold water, easiness in construction, high binding performance, capability of preventing cracking and shedding of a plaster layer, improved binding strength and smoothness and convenience in storage and transport, and further, is mainly applicable to being used as binder, filmogen, flatting agent and humectants in construction coating and inner-wall or outer-wall putty, or can be used with cement, talcum powder, putty powder, gray calcium powder, plaster products, waterproof materials and the like or can be used independently and has high improved binding performance and water-retaining property.

An apparatus and method are provided for measuring the viscosity of a fluid. The apparatus typically includes an inlet line that is configured to receive a flow of the fluid, and at least one porous medium column that receives the flow of the fluid from the inlet line and resists the flow so that a pressure of the fluid at the outlet is less than a pressure of the fluid at the inlet. A pressure sensor is configured to measure a pressure differential between an inlet and outlet of the column, and the sensor is adapted to determine the viscosity of the fluid according to the pressure differential and the permeability of the porous medium.

Disclosed is a resin composition comprising (A) a saponified ethylene-vinyl ester copolymer and (B) a completely or partially dehydrated polyvalent metal sulfate hydrate. Preferably, the component (B) is a completely or partially dehydrated 2-valent metal sulfate hydrate. The resin composition can suppress increasing viscosity in preparation thereof as well as production of the multilayer structure therefrom. A molded article can be stably produced and recover quickly gas barrier property deteriorated by hot water treatment and additionally maintain the superior gas barrier property.

Ophthalmic pharmaceutical compositions containing tobramycin, dexamethasone and deacetylated xanthan gum are described. The compositions provide longer ocular retention for enhanced ocular bioavailability of tobramycin and dexamethasone. In a preferred embodiment, the compositions also provide for improved suspension of dexamethasone. The concentration of ionizable species in the compositions is controlled so as to prevent precipitation of the xanthan gum as a result of ionic interactions between tobramycin and xanthan gum, while allowing for a restoration of viscosity upon topical application of the compositions to the eye. The use of deacetylated xanthan gum is disclosed, so as to avoid formulation instability caused by pH drift during storage.
