The present invention also pertains to methods of making such composite cathodes, cells comprising such composite cathodes, and methods of making such cells.

A low-hydrogen photovoltaic cell is disclosed. The photovoltaic cell may contain less than 5% hydrogen. In one aspect, the photovoltaic cell may contain substantially no hydrogen, that is, the photovoltaic cell may be substantially hydrogen free. The photovoltaic cell includes a substrate and an absorber deposited on to the substrate. The absorber may typically include elements from group 11, group 12, and group 13 of the Periodic Table, for example, copper, indium, and gallium. The absorber may be treated with selenium and / or sulfur to produce a CIGS or CIGSS-type photovoltaic cell. The low-hydrogen photovoltaic cell may fabricated by a method and apparatus adapted to control metalloid vapor delivery, for example, in a low-hydrogen or hydrogen free atmosphere.

A method of administering parenterally, particularly intramuscularly, glutamine and cystine and glycine plus selenium; or lactalbumin plus selenium; or lactalbumin and glutamine and cystine and glycine plus selenium, through a long-acting pharmaceutically acceptable carrier to a patient. The method comprises injecting a mixture of glutamine, cystine, glycine, lactalbumin and selenium in order to maintain the mixture systemically or locally for a sufficient time period so as to maintain blood levels of glutathione within an improved therapeutic range.

Adsorbents for removing anions of a heavy metals comprise a porous carbon in which at least one oxygen-containing compound of iron, copper, and / or aluminum is incorporated. The oxygen-containing compound may be incorporated into the porous carbon by impregnation or dispersion of a suitable precursor of such a compound. The precursor may be further treated to yield the oxygen-containing compound. Such adsorbents are particularly useful for removing arsenic and / or selenium from the environment and may be used in treating drinking water sources.

In an energetic-beam detection apparatus having a selenium detector which includes a substrate and an energetic-beam absorber being formed on the substrate and containing selenium, a temperature detecting unit detects a temperature of the selenium detector, and a temperature control unit controls the temperature of the selenium detector so that the temperature is maintained in a predetermined range when the selenium detector is in operation. Alternatively, when the temperature of the selenium detector is outside a predetermined range, an operation suppressing unit suppresses the operation of the selenium detector, or a notification unit notifies a user of the deviation of the temperature of the selenium detector from the predetermined range.

The invention relates to a method for planting pollution-free rice rich in selenium by adopting biotechnology, belonging to a planting method of plants; the planting method comprises the steps of land selection, soil preparation, application of the soil activator Medina, variety selection and seed treatment, seedling strengthening by means of dry raising and spaced planting cultivation, timely rice transplanting and reasonable compact planting, adequate fertilization, scientific irrigation, adoption of selenium supplementing and transforming technology, comprehensive prevention and control of diseases and pests, harvesting and threshing, drying and storing. The method of the invention has obvious effect; proved by field production trials, the application of the biologics of the Medina can increase the plant yield by 20 percent to 40 percent and decrease the fertilizer dosage by 25 percent to 50 percent and improve the rate of emergence in saline and alkali waste lands by 40 percent to 80 percent; the method can overcome diseases of continuous cropping effectively, eliminate soil crusting and optimizing greenhouses, etc. so as to preserve the soil properties of land capability.

This invention discloses the synthesis of metal chalcogenides using chemical vapor deposition (CVD) process, atomic layer deposition (ALD) process, or wet solution process. Ligand exchange reactions of organosilyltellurium or organosilylselenium with a series of metal compounds having neucleophilic substituents generate metal chalcogenides. This chemistry is used to deposit germanium-antimony-tellurium (GeSbTe) and germanium-antimony-selenium (GeSbSe) films or other tellurium and selenium based metal compounds for phase change memory and photovoltaic devices.

The invention provides a selenium-rich coating agent, a selenium-rich seed and a preparation method of the selenium-rich seed. The selenium-rich coating agent comprises, by weight, 0.1-1.5 parts of selenium fertilizer, 0.1-8 parts of microelements, 1.5-100 parts of film-forming agents, 0.02-2 parts of insecticide, 0.03-4 parts of sterilizing agents and 0.03-4 parts of plant growth regulators.
