A series of benzyl-containing ammonium salts, p-alkylbenzyltrimethylammonium halides (C(n)BA: 1a-c) and alkylbenzyldimethylammonium halides (C(n)AB: 2a-d), have been prepared and their photodegradabilities in aqueous solutions have been compared. The photolytic decomposition proceeded by heterolytic and homolytic cleavages of the benzyl-nitrogen bond. The conversion yields were almost the same for all surfactants, whereas the product yields were slightly dependent on the alkyl-chain length. After irradiation, C(8)BA (1b) and C(12)BA (1c) were converted to non-surfactants, whereas C(12)AB (2c) and C(16)AB (2d) still remained surface-active. Their solution properties were concomitantly changed.

A novel low-power gate driver architecture was developed for large 8 K 120 Hz liquid crystal display panel. For this application, not only high-speed driving but also low power consumption is required. We employed a high mobility In-Ga-Zn-O, dual V GL level driving method, and gate driver circuit driven by DC supply. The simulation results show that our proposals meet 8 K 120 Hz driving requirements. Also, we have fabricated a prototype panel and confirmed both high-speed driving and low power consumption.

A photodegradative surfactant, p-dodecylbenzyltrimethylammonium bromide, was used as an emulsifier for micro-emulsion polymerization of methyl methacrylate in water. The resulting polymer latex was coagulated during UV irradiation. The analysis of the centrifuged solid after irradiation indicated almost perfection of both recovery of the polymer and removal of surface-active species from it.
