The present invention concerns methods and compositions for stably tethered structures of defined compositions, which may have multiple functionalities and / or binding specificities. Preferred embodiments concern hexameric stably tethered structures comprising one or more IgG antibody fragments and which may be monospecific or bispecific. The disclosed methods and compositions provide a facile and general way to obtain stably tethered structures of virtually any functionality and / or binding specificity. The stably tethered structures may be administered to subjects for diagnostic and / or therapeutic use, for example for treatment of cancer or autoimmune disease. The stably tethered structures may bind to and / or be conjugated to a variety of known effectors, such as drugs, enzymes, radionuclides, therapeutic agents and / or diagnostic agents.

Tobaccos are cured in a manner so as to provide tobaccos having extremely low tobacco specific nitrosamine (TSNA) contents. Harvested Virginia tobacco is subjected to flue-curing so as to provide flue-cured tobacco. During the curing processing steps, contact of the tobacco with nitric oxide gases, such as those produced as combustion products of propane burning heating units, is avoided. Tobacco in curing barns is not subjected to direct-fire curing techniques, but rather, heat for tobacco curing can be provided by heat exchange or electrical heating methods.

Methods, devices, and systems for a) revascularization and / or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and / or closing such extravascular passageways.

A method of manufacturing improved thin-film solar cells entirely by sputtering includes a high efficiency back contact / reflecting multi-layer containing at least one barrier layer consisting of a transition metal nitride. A copper indium gallium diselenide (Cu(InXGa1−X)Se2) absorber layer (X ranging from 1 to approximately 0.7) is co-sputtered from specially prepared electrically conductive targets using dual cylindrical rotary magnetron technology. The band gap of the absorber layer can be graded by varying the gallium content, and by replacing the gallium partially or totally with aluminum. Alternately the absorber layer is reactively sputtered from metal alloy targets in the presence of hydrogen selenide gas. RF sputtering is used to deposit a non-cadmium containing window layer of ZnS. The top transparent electrode is reactively sputtered aluminum doped ZnO. A unique modular vacuum roll-to-roll sputtering machine is described. The machine is adapted to incorporate dual cylindrical rotary magnetron technology to manufacture the improved solar cell material in a single pass.

A first electrophoretic medium comprises an electrically charged particle suspended in a suspending fluid, the particle having a polymeric shell having repeating units derived from at least one monomer the homopolymer of which is incompatible with the suspending fluid. A second, similar electrophoretic medium comprises a suspending fluid, and first and second types of electrically charged particle suspended in the suspending fluid, the two types of particle having differing optical characteristics but both having polymeric shells. The polymeric shells are arranged such that homoaggregation of the two types of particles is thermodynamically favored over heteroaggregation.

A method of starting up a gas phase polymerization reactor, comprising controlling an amount of hydrocarbon absorbed in a polymer seedbed during startup to avoid formation of agglomerates or sheeting on an interior wall of the reactor. A system for of starting up a gas phase polymerization reactor, comprising a controller coupled to the polymerization reactor and controlling an amount of hydrocarbon absorbed in a polymer seedbed during startup to avoid formation of agglomerates or sheeting on an interior wall of the reactor.
