A novel three-dimensional Ag nanoparticles/reduced graphene oxide microtubular field effect transistor sensor for NO detections.

A novel three-dimensional (3D) microtubular NO field effect transistor (FET) sensor has been fabricated from 2D reduced graphene oxide (rGO) nanosheets decorated with Ag nanoparticles, by applying the self-roll-up technique. The electrical properties of 2D and 3D Ag NP/rGO FET sensors have been investigated and compared. Finally, the performance of the 3D sensors has been demonstrated, where the preliminary results show that our 3D Ag NP/rGO FET NO sensor exhibits a relatively fast response (response time of 116 s) to 20 parts per million NO with a response of 4.

A Novel Three-Dimensional Ag nanoparticles/rGO Microtubular Field Effect Transistor Sensor for NODetections.

Abstract：A novel three-dimensional (3D) microtubular NOFET sensor has been fabricated from the two-dimensional (2D) reduced graphene oxide (rGO) nanosheets decorated with Ag nanoparticles, by applying the self-roll up technique. The electrical properties of 2D and 3D FET Ag NPs/rGO sensors have been investigated and compared. Finally, the performance of the 3D sensors has been demonstrated, where the preliminary results shown that our 3D FET Ag NPs/rGO NOsensor exhibit a relative fast response (response time of 116 s) to 20 part per million (ppm) NOwith a response of 4.

A comparison of hazard perception and hazard prediction tests across China, Spain and the UK.

Hazard perception (HP) is the ability to spot on-road hazards in time to avoid a collision. This skill is traditionally measured by recording response times to hazards in video clips of driving, with safer, experienced drivers often out-performing inexperienced drivers. This study assessed whether HP test performance is culturally specific by comparing Chinese, Spanish and UK drivers who watched clips filmed in all three countries.

Impulsivity and risky decision making among taxi drivers in Hong Kong: An event-related potential study.

Taxi drivers play an important role in providing safe and professional public transport services. However, they tend to be more involved than other professional driver groups in accidents caused by deliberate recklessness. This study used an event-related potential (ERP) experiment to examine risk-taking behavior arising from impulsivity by comparing the underlying neural processes of taxi drivers with and without traffic offence records in Hong Kong.

Assessments of risky driving: a Go/No-Go simulator driving task to evaluate risky decision-making and associated behavioral patterns.

This study sought to develop and validate a Go/No-Go Simulator Driving Task (G/NG-SDT) to evaluate driver risky decision-making and associated behavioral assessments at a situation-specific level. Eighty-four participants were instructed to complete a route in as short time as possible, but avoiding any violations or crashes. To achieve this aim, they had to decide to go or wait in the dilemma scenes, paired with the baseline scenes in several scenarios.

Risk-taking on the road and in the mind: behavioural and neural patterns of decision making between risky and safe drivers.

Unlabelled: Drivers' risk-taking is a key issue of road safety. This study explored individual differences in drivers' decision-making, linking external behaviours to internal neural activity, to reveal the cognitive mechanisms of risky driving. Twenty-four male drivers were split into two groups (risky vs.
