Graphene aerogels, also known as GCEs, are lightweight and highly flexible materials that have shown great promise in various applications. They are made from carbon nanotubes and liquid nitrogen gas and can be used as a substitute for conventional materials such as plastics or metals.
(how large a cube is a gram of graphene aerogel)
However, one question that has been raised is how much mass does a small cube of graphene aerogel weigh? To answer this question, we need to know the dimensions of the cube and convert it into grams.
The dimension of a single cube of graphene aerogel can vary depending on the specific properties of the material. However, generally speaking, the size of a typical cube will be smaller than a few millimeters in diameter and larger than a few centimeters in length. The most commonly used sizes for testing are 10mm x 10mm x 10mm (diameter x height x length), which produces a total mass of around 0.5g.
To calculate the weight of a cube of GCEs, we first need to multiply its volume by its density. Graphene aerogels have a low density compared to other materials, with a density of about 2.4 grams per cubic centimeter at room temperature. Therefore, the volume of a cube of GCEs will be approximately equal to its surface area multiplied by the density:
Volume = Surface Area x Density
V = (6 x A x B) / 4
where V is the volume, A is the surface area, and B is the breadth. We can rearrange this equation to solve for the volume in terms of the surface area:
A = V x 4 / (6 x B)
Substituting the value of V from above, we get:
A = (0.5g) x 4 / (6 x 0.1cm) = 0.25 cm^3
Therefore, the surface area of a single cube of GCEs is 0.25 square centimeters. Using this information, we can calculate the volume of a cube using the formula above:
V = A x D
where V is the volume, A is the surface area, and D is the diagonal length. Assuming a cube with a side length of 1mm, we can calculate the diagonal length as follows:
D = √(2 x (A + B))
Solving for D, we get:
D = √(2 x (0.25 cm^3 + 0.1 cm^3)) = √(0.4 cm^3) = 0.2 cm
Now that we have the volume and diagonal length of the cube, we can calculate the weight using the formula above:
Weight = Volume x Density
Weight = (0.5 g) x 2.4 g/cm^3 = 1.2 g

Therefore, the weight of a small cube of graphene aerogel is around 1.2 grams. This means that even a small cube of GCEs can still have a significant impact on the performance of certain applications due to their unique properties.
