Abstract: The present invention discloses a wide angle backlight lens which consists of lens mounting plate and lens body. Further, the upper outer surface of lens body is fixedly connected with the central position of the lower outer surface of lens mounting plate. Four sets of lens stands are installed near four corners of the upper outer surface of said lens mounting plate. Each set of said lens stands consists of two assembling stands. The luminous slot (4) is installed in the central position of the lower outer surface of said lens body (2) and lamp mounting slot (5) and reflective aperture (6) are installed in the central position of the upper outer surface of said lens mounting plate (1). A wide angle backlight lens described in the present invention is available for convergence and divergence of light rays according to actual needs, to improve the range of light diffusion and luminous intensity, hence realizing a higher uniformity of flares.

Abstract: A self-lubricating rolling bearing is provided. The chemical compositions in the inner rings and the outer rings of bearing are 3.4-3.7% C, 2.7-2.9% Si, 0.3-0.5% Mn, 0.3-0.5% Cr, ?0.05% S, ?0.05% P, 0.03-0.045% Residual Mg, and the remainder Fe. The total percent of the chemical compositions is 100%. The material for the inner and outer rings of the rolling bearing introduced in the invention is austempered ductile iron (ADI). In the microstructure of ADI, the diameter of the graphite nodules is less than 0.02 mm, the number of graphite spheres per square millimeter is more than 400, and the microstructure of the metal matrix in the ADI can be showed clearly only when it is observed on the microscope with a magnification more than 500. Eventually, the self-lubricating rolling bearings are made from the ADI.

Abstract: Flowing supercritical CO2 is used to activate metal organic framework materials (MOF). MOFs are activated directly from N,N-dimethylformamide (DMF) thus avoiding exchange with a volatile solvent. Most MCPs display increased surface areas directly after treatment although those with coordinatively unsaturated metal centers benefit from additional heating.
