摘要:
A quaternary oxide includes a dopant metal, a dopant nonmetal, titanium, and oxygen. The atomic ratio of titanium, oxygen and dopant nonmetal may be 1:0.5-1.99:0.01-1.5. Quaternary oxides may be used in catalytic compositions, in coatings for disinfecting surfaces and in coatings for self-cleaning surfaces. A method of making a quaternary oxide includes combining ingredients including a titanium source, a dopant nonmetal source, a dopant metal salt, and a polar organic solvent to form a reaction mixture; and heating the reaction mixture.

A label printer is provided. The label printer comprises a stationary housing (100) and a side cover (200) which are rotationally connected; a mechanism set is fixed in the stationary housing; at least two fixed shafts are set between a first side plate (800) and a second side plate (801) of the printer module frame; a pinch plate (5) used to support the second side plate is rotationally installed at the side of the mechanism base; a printer set (10,2,1) between the first side plate and the second side plate. The label printer in the invention is convenient to change or assemble the consumable.

摘要:
A system and method for analyzing data from a gel permeation chromatography (GPC) or size exclusion chromatography (SEC) system fro determining a polymeric sample's radius of gyration. Data from two or more detectors is used with a least-squares minimization fit. A novel method includes the simultaneous determination of a sample's radius of gyration using data from a light scattering detector that collects data from at least two incident angles. Detectors within the inventive method include a multi-angle light scattering (LS) detector, viscometer (V) and a refractive index (RI) detector.
