Ultrafast synthesis of nickel-ruthenium hydroxide ultrathin nanosheets decorated nickel sulfide with efficient overall water splitting.

Nickel sulfide (NiS) demonstrates exceptional charge transfer capabilities, positioning it as an ideal substrate for hosting active sites in water electrolysis. However, the development of such materials has been hindered by intricate post-modification strategies. Here, a rapid hydrolysis strategy is reported to promote the fast growth of ultrathin nickel-ruthenium hydroxide nanosheets on NiS supported by nickel foam (RuNiOH/NiS/NF).

Design and Research of Remote Monitoring System for Sports Injury Rehabilitation Training.

In order to study the sports injuries that often occur in athletes' training and competition and solve the problems of low monitoring accuracy of injury mode data and large difference of resistance signal waveforms in the traditional monitoring system, this paper proposes the application of wireless sensor network in monitoring process. The accuracy of data monitoring with 9 different degree injury modes set by 1-9 squares in the traditional system is lower, while the accuracy of sports injury rehabilitation monitoring based on wireless sensor network is higher, which can be maintained above 90%. The experimental results show that the monitoring system has high monitoring accuracy of damage mode data and small difference of resistance signal waveform.
