摘要:
A method is presented describing in situ preparation of the titania-based sol-gel PDMS coating and its immobilization on the inner surface of a fused silica microextraction capillary. Sol-gel titania-poly (dimethylsiloxane) (TiO2-PDMS) coating was developed for capillary microextraction (CME) to perform on-line preconcentration and HPLC analysis of trace impurities in aqueous samples. The sol-gel titania-based coatings demonstrated strong pH stability and enhanced extraction capability over other commercially available GC coatings. Extraction characteristics of a sol-gel titania-PDMS capillary remained practically unchanged after continuous rinsing with a 0.1 M NaOH solution (pH=13) for 12 hours.

A method is for programming a memory block of a non-volatile memory device. The non-volatile memory device is operatively connected to a memory controller, and the memory block defined by a plurality of word lines located between a string select line and a common source line corresponding to the string select line. The method includes programming a first sub-block of the memory block, determining in the non-volatile memory device when a reference word line is programmed during programming of the first sub-block, and partial erasing a second sub-block of the memory block upon determining that the reference word line is programmed during programming of the first sub-block.

Various embodiments of a warning indicator for use with wiper blades are provided. In one embodiment, the warning indicator has a housing, a counting unit disposed in the housing, an indicating unit exposed on the housing and an electrical source. The housing is coupled to an oscillating wiper blade of a windshield wiper device. The counting unit is configured to detect oscillating movements of the wiper blade one at a time. The counting unit is configured such that an oscillating number of the wiper blade is accumulatively increased. The indicating unit indicates a warning under control of the counting unit when the oscillating number comes to a predetermined value. The electrical source supplies an electrical power to the counting unit and the indicating unit.
