The importance of shape in the adsorption of nitrogen, carbon dioxide and methane (common molecular probes for solid characterization) on surfaces and in confined spaces is investigated for its effects on the adsorption capacity and isosteric heat. We study the possibility of using an equivalent ...
Molecular geometry describes the overall shape of a molecule in terms of how the atoms inside it are arranged. Examples of simple structures are linear molecules like carbon dioxide (0=C=0) and tetrahedral molecules like methane, which consists of a carbon atom with four hydrogen atoms surroundin...
TO BE SOLVED: To prepare a molecular sieve carbon film having good selective permeability, high strength, and heat resistance by making a carbon film having a carbon content of at least a given value and lots of pores adhere to the surface of a porous ceramic material of a specified shape....
In a time-resolved Coulomb explosion imaging study using ultrafast extreme ultraviolet pulses, combined with theoretical simulations, authors reveal unexpected asymmetric rearrangement of carbon dioxide dimer ion, including a CO3 moiety formation.

Table 9.1 shows that the molecular weight of atmospheric nitrogen is higher than that of pure nitrogen; this is because ‘atmospheric nitrogen’ is taken to be a mixture of nitrogen and about 1.8% by mass of argon, carbon dioxide and other gases: the molecular weight of atmospheric nitrogen ...
