    摘要: A process is provided for oxygenating alkyl-substituted aromatic compounds. In the process alkyl-substituted aromatic compounds are contacted with molecular oxygen in the presence of a suitable monocarboxylic acid, an at least partially soluble Te or Se compound, an inorganic bromine compound, and a compound selected from inorganic nitrates and compounds convertible to inorganic nitrates at conditions of the process. In an embodiment of the invention the process is carried out in two distinct steps with contact of the alkyl-substituted aromatic compounds and oxygen in the presence of the essential components produce an ester comprising both an aromatic alcohol and the carboxylic acid with subsequent hydrolyzing of this ester to produce an aromatic alcohol with regeneration of the carboxylic acid.

    摘要: Semiconducting metal silicide electromagnetic radiation sources and detectors have a thin film of semiconducting metal silicide grown or deposited on a silicon wafer. The metals are chosen from a group consisting of iron, iridium, manganese, chromium, rhenium, barium, calcium, magnesium and osmium. The detectors are intrinsic semiconductors and can be formed either as discrete devices, or monolithically on a silicon chip to provide an integrated detector or detector array. The semiconducting metal silicide devices are efficient detectors at wavelengths which mate with the transmission capabilities of certain optical fibers enhancing the combination of infra-red detectors and optical fiber transmission preveously known. Iron disilicide is useful as an infra-red radiation source and as an extrinsic detector as well.

    摘要: Semiconducting metal silicide electromagnetic radiation detectors have a thin film of semiconducting metal silicide, such as rhenium disilicide, grown or deposited on a silicon wafer. The detectors are intrinsic semiconductor detectors and can be formed either as discrete devices, or monolithically on a silicon chip to provide an integrated detector or detector array. The semiconducting rhenium disilicide detectors are efficient at wavelengths which mate with the transmission capabilities of certain optical fibers, thereby enhancing the combination of infrared detectors and optical fiber transmission previously known. The range of electromagnetic radiation sensed by these rhenium disilicide detectors include the infrared range of wavelengths up to 14 microns.
