Abstract: A low alloy or mild steel weld containing a slag-modifying additive selected from the group consisting of antimony, bismuth, germanium and compounds thereof; A weld wire for forming a low alloy or mild steel weld containing a slag-modifying additive selected from the group consisting of antimony, bismuth, germanium and compounds thereof.
Abstract: A method and composition for hyperthermally diagnosing and monitoring treatment of cells in an animal with photoacoustic sound and nanoparticles. The heat (temperature) and photoacoustic sound wave production inside the target tissue is measured. The desired temperature is achieved using a laser and photoacoustic imaging technique. Hyperthermia treatment of tissue in a target site applies a heat source to kill cells without protein denaturation. The method introduces an encapsulated dye that is released at a selected temperature in the target site to indicate that a threshold temperature has been reached to hyperthermally treat the tissue. In one embodiment, the composition releases the dye at a temperature of 42° C. to 56° C., and preferably about 45° C. to 49° C. The composition which can be a liposome composition encapsulating the dye can be introduced to the bloodstream of the patient to flow through the target site.
Abstract: In one aspect, the invention features a method and device for measuring blood concentration of a substance such as glucose in the aqueous humor by illuminating the aqueous humor with a light source at a frequency that is absorbed by the substance to the measured, and then sensing photoacoustically generated sound waves originated within the aqueous humor as a consequence of illumination by the light source. The blood concentration can be estimated from the amplitude of the sound waves received. The method may be combined with other optical techniques for glucose measurement and/or with optical or ultrasonic techniques for topographic mapping of eye structures.

Abstract: Disclosed is a method of exfoliating a layered material (e.g., graphite and graphite oxide) to produce nano-scaled platelets having a thickness smaller than 100 nm, typically smaller than 10 nm, and often between 0.34 nm and 1.02 nm. The method comprises: (a) subjecting the layered material in a powder form to a halogen vapor at a first temperature above the melting point or sublimation point of the halogen at a sufficient vapor pressure and for a duration of time sufficient to cause the halogen molecules to penetrate an interlayer space of the layered material, forming a stable halogen-intercalated compound; and (b) heating the halogen-intercalated compound at a second temperature above the boiling point of the halogen, allowing halogen atoms or molecules residing in the interlayer space to exfoliate the layered material to produce the platelets.
Abstract: A separation device with a gas inlet port that accepts an inlet gas. The inlet gas is composed of a mixture of at least two separable particle components with each component having a different mass. A rotating separation rotor accepts the inlet gas and uses a separator to substantially separate the gas according to mass into two fractions, a heavier and a lighter fraction. One of the fractions is passed to a second separator that further separates that fraction into another two fractions consisting of heavier and lighter fractions. The desired fractions are collected and exhausted from the separation device for use.
Abstract: The present invention provides a process for producing nano graphene platelets (NGPs) that are dispersible and conducting. The process comprises: (a) preparing a graphite intercalation compound (GIC) or graphite oxide (GO) from a laminar graphite material; (b) exposing the GIC or GO to a first temperature for a first period of time to obtain exfoliated graphite; and (c) exposing the exfoliated graphite to a second temperature in a protective atmosphere for a second period of time to obtain the desired dispersible nano graphene platelet with an oxygen content no greater than 25% by weight, preferably below 20% by weight, further preferably between 5% and 20% by weight. Conductive NGPs can find applications in transparent electrodes for solar cells or flat panel displays, additives for battery and supercapacitor electrodes, conductive nanocomposite for electromagnetic wave interference (EMI) shielding and static charge dissipation, etc.
Abstract: A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section of the modified planetary roller extruder, conveying the raw materials from the feeding section to a compounding section of the modified planetary roller extruder, continuously mixing the primary raw materials in the compounding section to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material.

Abstract: A method and system for electronically clearing financial instruments may include receiving electronic files of items containing data scanned from financial instruments including an amount of each instrument, and applying a rule to sort the items by determining whether the item may be stored or forwarded for clearing without storage. The rule may include determining whether an amount of the instrument exceeds a predetermined value, and if so, forwarding the instrument for clearing, or if not, storing the item for forwarding at a later time when the per item fee for clearing is lower. The system may include a control for receiving electronic files from a scanning device and applying a rule to sort the files by determining whether each file should be stored or forwarded and an image export server for converting the files to a preferred format and transmitting them for clearing.
