In short sentence

Expert Solution

Recently, it has been found that carbon nanotubes (CNTs) and graphene could prove to be the most promising carbonaceous fillers in polymers nanocomposites field because of their better structural and functional properties. Their uniform dispersion in polymer matrix leads to significant improvements in their several properties. Polycarbonate/carbon nanotube (CNT) nanocomposites were generated using a supercritical carbon dioxide (scCO₂) aided melt blending method, yielding nanocomposites with enhanced electrical properties and improved dispersion while maintaining the aspect ratio of the as-received CNTs.

The dielectric properties were investigated for (PC/BT/CB) nanocomposites films in the frequency range from 50 Hz-20 MHz and temperature in the range 40-150 °C. Optical and electrical properties of these nanocomposites were modified by adjusting the CB and BT nanoparticles weight percentage in the PC matrix. The nanocomposite shows high dielectric constant with low dielectric loss. Such high-k nanocomposites can be used as a suitable candidate for high-k capacitor or embedded capacitor.

study compared three different display panels for use by air traffic controllers. Each display panel was test in a simulated emergency condition; 12 highly trained air traffic controllers took part in the study. Four controllers were randomly assigned to each display panel. The time (in seconds) needed to stabilize the emergency condition was recorded. The results of are given below. Let μ, μB, and μC represent the mean times to stabilize the emergency conditions when using display panels A, B,...

A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel–emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The resulting data and analysis results are given below.
