十六烷基三甲基溴化铵在葫芦[6]脲水溶液中的胶束化行为及分子间包络行为

通过表面张力、核磁共振以及热重分析等手段研究了葫芦脲[6]对十六烷基三甲基溴化铵(CTAB)在水溶液体系中胶束化行为的影响规律及分子间包络行为。计算了体系的临界胶束浓度及CTAB与CB[6]形成的包络物的包络计量比和包络常数,其包络计量比和包结常数分别为1:1和2.8×103L/mol。结果表明,CB[6]对CTAB的胶束化有较显著的影响,CB[6]的加入延迟了CTAB胶束的生成。核磁共振及热重分析进一步证明了主客体的包络行为及包络增加了包络物的热稳定性。

Remote Navigation of Turtle by Controlling Instinct Behavior via Human Brain-computer Interface

Brain-Computer Interface （BCI） techniques have advanced to a level where it is now eliminating the need lor hand-based activation. This paper presents a novel attempt to remotely control an animal＇s behavior by human BCI using a hybrid of Event Related Desynchronization （ERD） and Steady-State Visually Evoked Potential （SSVEP） BCI protocols. The turtle was chosen as the target animal, and we developed a head-mounted display, wireless communication, and a specially designed stimulation device for the turtle. These devices could evoke the turtle＇s instinctive escape behavior to guide its moving path, and turtles were remotely controlled in both indoor and outdoor environments. The system architecture and design were presented. To demon- strate the feasibility of the system, experimental tests were performed under various conditions. Our system could act as a framework for future human-animal interaction systems.
