Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
Abstract:
The present invention provides a transition metal/polymer matrix composite material which has durable, wear and corrosion resistant and friction reducing characteristics which can be used in a powder or liquid form, or, which can be bonded to a desired surface at ambient temperature. The specific components are transition metal dichalcogenide (TMDs) disulfides of tungsten and molybdenum, and the polymer polytetrafuoroethylene (PTFE). This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) and creates a synergistic interaction optimizing the friction reducing properties of PTFE with similar friction reducing properties of select TMD's, and, the TMD's additional wear-resistance and natural tendency for forming a tenacious physical bond at a molecular level. The invention comprises a mixture of PTFE and TMDs (particularly tungsten disulfide and molybdenum disulfide) which can be applied to a substrate through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 micron to 60 microns thick.
Abstract:
Thin impermeable, surface hardened, corrosion-resistant, durable, dry lubricant surface finishes are provided as well as surface finished products and methods for the production thereof. The surface finishes comprise particulate mixtures of sulfur containing metallic compounds and fluorocarbon polymers and are applied to surfaces of substrates such as metallic surfaces.

Abstract:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent—although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
