Injectable insulin formulations that are capable of modifying the amount of insulin released based on the patient's tissue glucose levels, methods for making and using these formulations are described herein. The formulation may be administered via subcutaneous, intradermal or intramuscular administration. In one preferred embodiment, the formulations are administered via subcutaneous injection. The formulations contain insulin, an oxidizing agent or enzyme and a reducing agent or enzyme, a diluent and optionally one or more thickening agents. If a thickening agent is present in the formulation, the thickening agent increases the viscosity of the formulation following administration. Preferably the formulation contains an insulin, a diluent, glucose oxidase and peroxidase. Following administration to a patient, the insulin is released from the formulations as a function of the patient's tissue glucose level, which in turn maintains the patient's blood glucose level within an optimum range. The formulation is often referred to as a “smart” formulation since it modifies its release rate of insulin according to the patient's needs at a particular time. In a preferred embodiment, the formulation is designed to release insulin into the systemic circulation over time with a basal release profile following injection in a patient. In another embodiment, the formulation is designed to release insulin into the systemic circulation over time with a non-basal release profile following injection in a patient, such as a regular human insulin release profile or a prandial release profile.

The invention provides polymeric matrices and films comprising fixation reagents that are capable of reacting with solubilized metals to form less soluble metal compounds. The fixation reagenst may include inorganic sulfides and phosphates, as well as adsorbents. The polymeric matrices may be comprised of polyvinyl alcohols and polyvinyl acetates. In some embodiments, the polymeric matrix is selected to be at least as soluble as the selected fixation reagent, particularly under the conditions in which the matrix is expected to come into contact with the solublized metal.

This invention relates to a process for producing an improved cathode powder for making lithium ion batteries wherein the powder comprises lithium, vanadium and a polyanion. The process includes forming a solution-suspension of the precursors, which include vanadium pentoxide, with a reducing agent, a solvent, and a carbon-residue-forming material. The reducing agent causes the vanadium in vanadium pentoxide to reduce from V5+ to V3+. The solution-suspension is heated in an inert environment to drive the synthesis of the LVP (Li₃V₂(PO₄)₃) such that the carbon-residue-forming material is also oxidized to precipitate in and on the LVP forming carbon-containing LVP or CCLVP. The liquids are separated from the solids and the dry powder is heated to a second higher temperature to drive the crystallization of the product. The resulting product retains a small particle size, includes carbon in the LVP for conductivity and is created with very low cost precursors and avoids the need for milling or other processing to reduce the product to a particle size suitable for use in batteries. It also does not require the addition of carbon black, graphite or other form of carbon to provide the conductivity required for use in batteries.

Systems and methods for generating, converting, and/or storing power under the ground level are disclosed. A well buoyancy power system includes a well adapted to hold a liquid and sealed to hold a pressurize gas, a buoyancy engine that can be a conveyor buoyancy engine or an elevator buoyancy engine, a generator coupled to the buoyancy engine, and an air mover located in the bottom air chamber to transmit the pressurized gas into the liquid at the lower part of the well to drive the buoyancy engine. The system may not be sealed and pressurized for cheaper storage of air when not reused. Because the system utilizes underground space, it is safe, low or no noise, non-polluting, and aesthetically neutral for deployment near where power is to be used such as population centers.

Disclosed herein is a method of removing an organic material from an electronic device substrate surface. The method is particularly useful when the device substrate includes exposed metal. According to the present method, an electronic device substrate surface is exposed to a solution comprising ozone (O₃) at a concentration ranging from about 45 ppm to about 600 ppm in a solvent consisting of pure propionic acid or propionic acid in combination with deionized water or a carbonate having from 2 to 4 carbons. The method is particularly useful in the manufacture of large surface areas covered with device structures, such as electronic TFT flat panel displays, solar cell arrays, and structures containing light-emitting diodes. The method is also useful for removing organic materials from the surface of solid state device-containing semiconductor substrates.

One aspect of the invention relates to a method for producing an edible aqueous liquid composition that has been supplemented with a first mineral selected from the group of metals consisting of calcium, magnesium, potassium, zinc, copper, iron, manganese and a second mineral, different from the first mineral, that is selected from the same group of metals.

Another aspect of the present inventions relates to a reconstitutable powder containing:

• • 0.01-3 mmole of the first mineral per gram of powder;
  • 0.02-4 mmole of the second mineral per gram of powder;
  • 0.02-8 mmole of acid per gram of powder, said acid being selected from the group consisting of citric acid, tartaric acid, malic acid, phosphoric acid and combinations thereof;
  • 0.02-0.99 g of soy protein per gram of powder; and
  • less than 10 wt. % of water.

Polyimide precursors contained in resin compositions of the present invention have a polymer structure unit represented by formula (1) below:

wherein chemical structure A² includes an alicyclic compound but not an aromatic compound such as a benzene ring so that they provide excellent light transmission over a wide wavelength range. The polyimide precursors are imidized at 7.5% or more and 36% or less so that they are less soluble in developing solutions and therefore are not dissolved in the developing solutions at unexposed parts. Thus, the resin compositions of the present invention can be used to form a resin film having a precise pattern by exposure and development.

Patterning with UV and EUV light is described with organo tin sulfide (and selenide) clusters. The clusters are solids at room temperature and are soluble in organic solvents that are not too polar. Irradiation can either fragment a carbon metal bond or crosslink unsaturated organic moieties to stabilize the irradiated material. The irradiated material then resists dissolving in organic solvents so that the un-irradiated material can be contacted with an organic solvent to develop the latent image formed with the radiation. Radiation patternable layers can be formed through coating a solution or through vapor deposition. Corresponding precursor solutions, structures and methods are described.
