A High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles.

High internal phase emulsion foam having cellulose nanoparticles

A process for dispersing agglomerates or clusters of particles utilizing pressure generated from volatilization of an interstitial liquid. More particularly, the method relates to infusing the particles with a first liquid, placing the infused particles in a second liquid or fluid having a higher boiling point than the first liquid and heating the composition to a temperature above the boiling point of the first liquid thereby resulting in breakage of the particles. Compositions including particles dispersed by interstitial liquid vaporization are also disclosed.

A method for producing a High Internal Phase Emulsion foam is provided that comprises forming a first High Internal Phase Emulsion from an oil phase comprising monomer, crosslinking agent, emulsifier; and an aqueous phase. The High Internal Phase Emulsion is pumped into a water bath. The High Internal Phase Emulsion cures in the bath.

The invention provides a settling device comprising an acoustic wave generator and an inclined settling chamber. The angle &#x3b8; between the acoustic wave direction and the inclined settling chamber is greater than 0 and less than 90&#xb0;. The invention also provides a concentration method and a separation method using the device. The invention can be used to concentrate or separate particles such as inorganic particles, organic particles, and biological particles, for example, mammalian cells, bacteria, yeast, algae, and plant cells. The invention exhibits technical merits such as higher efficiency, cost-effectiveness, and large-scale production.

Acoustic device and methods thereof for separation and concentration

A method and apparatus for acoustically enhanced particle separation uses a chamber through which flows a fluid containing particles to be separated. A porous medium is disposed within the chamber. A transducer mounted on one wall of the chamber is powered to impose on the porous medium an acoustic field that is resonant to the chamber when filled with the fluid. Under the influence of the resonant acoustic field, the porous medium is able to trap particles substantially smaller than the average pore size of the medium. When the acoustic field is deactivated, the flowing fluid flushes the trapped particles from the porous medium and regenerates the medium. A collection circuit for harvesting the particles flushed from the porous medium is disclosed. Aluminum mesh, polyester foam, and unconsolidated glass beads are disclosed as porous media.

A micro-viscosity sensor for measuring the viscosity of a lubricant. The micro-viscosity sensor including at least one finger-like element or an array of finger-like elements vertically extending from the surface of a semiconductor base, the at least one finger-like element being oscillated at a desired frequency. The power required to oscillate the at least one-finger-like element is monitored because the power required is a function of the viscosity of the lubricant. The sensor also includes a temperature detector, wherein the thermal conductivity of the temperature detector varies in correspondence with the temperature of the lubricant. A first set of electrical contacts provides for electrical connection to the at least one finger-like element; and a second set of electrical contacts provides for electrical connection to the temperature detector. The viscosity of the lubricant is determined based on the temperature of the lubricant correlated with the power required to oscillate the at least one-finger like element at a particular frequency.

A method for separating particles from a flowing fluid suspension comprises the steps of providing an elongated chamber having closed first and second ends, flowing into the elongated chamber a fluid medium in which particles to be separated are suspended, and propagating an acoustic wave through the flowing fluid medium in the chamber. The acoustic wave is directed generally along the length of the chamber and is varied in frequency within a desired frequency range including a frequency resonant to the chamber to produce stationary coincidence excitations that separate particles from the fluid medium and urges the separated particles toward the second end of the chamber. The method also includes the steps of removing the fluid medium from the first end of the chamber and removing from the chamber the particles urged toward the second end of the chamber. The apparatus for separating particles from a flowing fluid comprises a tube having first and second open ends, a first outlet port adjacent the first end, a second outlet port adjacent the second end, and an inlet port intermediate the first and second end. Each end of the tube is closed by a spacer bonded to the tube end. A transducer is bonded to each spacer.
