Experiment : The Thickness of a Thin Aluminum Sheet

The density of aluminum is known, (2.70 g cm-3) and the mass of a piece of aluminum foil can be measured with a balance. The volume of the aluminum can then be calculated using the rearranged equation: V = m / D. Hence thickness of the aluminium foil

Particulate matter (PM10 and PM2.5)

Description. PM 10 is particulate matter 10 micrometers or less in diameter, PM 2.5 is particulate matter 2.5 micrometers or less in diameter. PM 2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application.

No 4: The Workhorse Finish

The practice in Australia is only to use 'No 4' as a description of a polished finish and it is not a rolled finish. The European standard, EN10088-2, defines two finishes, '2J' and '2K'. There is no prescription of the appearance or roughness of the '2J' finish, but '2K' is defined as surface Ra below 0.5 micrometres.

Supercapacitors are devices for rapid and efficient electrochemical energy storage and commonly employ carbon coated aluminum foil as the current collector. However, the thickness of the metallic foil and the corresponding added mass lower the specific and volumetric performance on a device level.
