Oxygen defects formed at the boundary between the zinc oxide type oxide semiconductor and the gate insulator are terminated by a surface treatment using sulfur or selenium as an oxygen group element or a compound thereof, the oxygen group element scarcely occurring physical property value change. Sulfur or selenium atoms effectively substitute oxygen defects to prevent occurrence of electron supplemental sites by merely applying a gas phase or liquid phase treatment to an oxide semiconductor or gate insulator with no remarkable change on the manufacturing process. As a result, this can attain the suppression of the threshold potential shift and the leak current in the characteristics of a thin film transistor.

These and other objects of this invention are achieved by providing a novel method and compositions for the clinical treatment of chronic inflammatory diseases. This invention involves use of systemically administered compositions which include primary amine derivatives of benzoic acid as carbonyl trapping agents. These primary therapeutic agents act by chemically binding to and sequestering the aldehyde and/or ketone products of lipid peroxidation. Increased levels of lipid peroxidation have been repeatedly demonstrated as a part of the non-enzymatic "inflammatory cascade" process which underlies the secondary etiology of chronic inflammatory diseases. p-Aminobenzoic acid (or PABA) is an example of the primary therapeutic agent of the present invention. PABA has a small molecular weight, is water soluble, has a primary amine group that reacts with carbonyl-containing metabolites under physiological conditions and is tolerated by the body in relatively high dosages and for extended periods. The carbonyl sequestering agents are used in combination with at least one co-agent so as to produce an additional beneficial physiological effect of an anti-inflammatory nature. Such compositions are administered systemically entirely via the oral route. Co-agents of the present invention include anti-oxidants and free radical trapping compounds (e.g., alpha-tocopherol), compounds having indirect anti-oxidant activity (e.g., selenium), vitamins (e.g., pyridoxine HCl), compounds which facilitate kidney drug elimination (e.g., glycine), metabolites at risk of depletion (e.g., pantothenic acid), sulfhydryl containing chemicals (e.g., methionine), compounds which facilitate glutathione activity (e.g., N-acetylcysteine), and non-absorbable polyamine co-agents (e.g., chitosan).

A recovery method for copper indium gallium selenide. The method includes firstly using a mixed solution of hydrochloric acid and hydrogen peroxide to dissolve the metal powder containing CIGS. After selenium is separated using hydrazine, copper is replaced by indium metal. Finally, indium and gallium are separated by a supported liquid membrane (SLM) combined with a dispersed stripping solution. The acid used in all the steps of the method is hydrochloric acid, so the copper indium gallium selenium can be separated one by one without the conversion of the solution during the operation, effectively reducing the process time and cost.
