There are two main types of adsorption, physisorption and
defined as adsorption in which the forces involved are intermolecular forces
(van der Waals forces) and which do not involve a significant change from the
gas phase electronic orbital patterns
of the species involved. Energies associated with physisorption is typically less
than 40 kJ mol-1.
Chemisorption is defined as adsorption in which the forces involved are the same kind as those operating in
the formation of chemical compounds which is on the magnitude of several 40-400
kJ mol-1 of gas adsorbed.
Cement or concrete are not really the same but they are complementary and both give the exact look for urban or industrial lifestyle. Not agressive on the eye, they still give that “dont mess with me” look you need and the strength to support your next bad-ass phase !
The pattern looks good in all three heights. Patterns don’t just stretch to fit, they were made in three different sizes. Patterns are really seamless in every direction : up, down, left and right.
