Abstract: A phosphorus-containing compound is treated with at least one metal compound prior to fractional distillation to collect a purified fraction containing about 20 ppb or less arsenic. The purified phosphorus-containing compounds are useful for preparing electronic materials for electronic semiconductor manufacturing. Suitable metal compounds include salts, oxides and/or sulfides of iron, copper, nickel, cobalt, or zinc.

Abstract: A uniform turnover apparatus comprises a turnover body, a linear advance device, and a fixed base. The linear advance device has a fixed end and a movable end. The fixed end is turnably provided on the fixed base by a first fulcrum. The turnover body is movably connected with the movable end of the linear advance device by a second fulcrum. The turnover body is turnably provided on the fixed base by a third fulcrum. The first, the second, and the third fulcra form a triangle. The uniform turnover apparatus comprises a control device connected with the linear advance device. The control device acquires an actual angular velocity at which the turnover body is turned, and compares the actual angular velocity with a set angular velocity, and according to the comparison, adjusts the linear velocity of the linear advance device in real time, so that the actual angular velocity of the turnover body approximates or equals to the set angular velocity.

Abstract: Disclosed are various embodiments of a platform telescoping system which comprises a platform, a first supporting arm, a second supporting arm, a telescopic driving mechanism which comprises a first power output, end and a rotational driving mechanism which comprises a second power output end. The first power output end is integrated with the second supporting arm and causes the second supporting arm to move in a first direction, and the second power output end is integrated with the platform and causes the platform to pivot between a first position and a second position. The second supporting arm telescopes with respect to the first supporting arm for adjusting the position of the platform. The space occupied by the platform telescoping system may be reduced while its functions enhanced.

Abstract: Improved biosensors are provided having excellent selectivity and stability properties, together with methods of preparing the biosensors. A preferred biosensor includes an electrode (12) having enzyme (16) deposited thereon together with a layer of electropolymerized polymer (18) intermingled with the enzyme (16); a crosslinked silane film (20) is applied over the polymer layer (18), and a final coating (22) of polyurethane is formed over the film (20). In preparative procedures, the enzyme (16) is electrodeposited using an aqueous enzyme solution containing a nonionic surfactant at a concentration level preferably in excess of the critical micelle concentration of the surfactant. In the case of a glucose sensor, the polymer layer (18) is preferably polyphenol, while the silane film is crosslinked (3-aminopropyl) trimethoxysilane. The preferred biosensors have greatly enhanced selectivity stabilities.
