Three dimensional molecular model of an all-carbon tubular fullerene. This is a list of notable computer programs that are used to model nanostructures at the levels of classical mechanics [1] and quantum mechanics. Furiousatoms [2] - a powerful software for molecular modelling and visualization; Aionics.io [3] - a powerful platform for ...
The example above would then be denoted M@C 60 if M were inside the carbon network. A more complex example is K 2 (K@C 59 B), which denotes "a 60-atom fullerene cage with one boron atom substituted for a carbon in the geodesic network, a single potassium trapped inside, and two potassium atoms adhering to the outside."

Fullerene purification is the process of obtaining a fullerene compound free of contamination. In fullerene production mixtures of C 60 , C 70 and higher homologues are always formed. Fullerene purification is key to fullerene science and determines fullerene prices and the success of practical applications of fullerenes.
An unusual example is the egg-shaped fullerene Tb 3 N@ C 84 , which violates the isolated pentagon rule. [ 60 ] Evidence for a meteor impact at the end of the Permian period was found by analyzing noble gases preserved by being trapped in fullerenes.
This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management systems, production management systems, digital twins.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
The method was simple and efficient to prepare the material in gram amounts per day (1990) which has boosted the fullerene research and is even today applied for the commercial production of fullerenes. The discovery of practical routes to C 60 led to the exploration of a new field of chemistry involving the study of fullerenes.
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software ; the GNU project in particular objects to their works being referred to as open-source . [ 1 ]
