The molecular simulations of the well-known high explosive beta-HMX (cyclotetramethylene tetranitramine) and its fluorine containing polymer-bonded explosives (PBXs) were carried out with the combination method of quantum mechanics, molecular mechanics and molecular dynamics. The atomic cluster model, ...
Orbital waves are formed by electrons that are confined to specific energy levels surrounding the nucleus of an atom. These atoms, because of their mass, exhibit quantum properties, and as the electrons circle the nucleus they act like a wave instead of like particles. What is an orbital wave...
(ONION method in Gaussian), the total energy (QM/MM energy) of the system is calculated stepwise. First, the total energy of the system (QM and MM regions) is evaluated using the MM methodology, followed by the incorporation of the isolated QM energy. Consequently, the MM energy of the ...
probability of finding an electron is greatest. QUANTUM NUMBERS – set of four numbers used to describe the electron’s energy level in terms of: a. distance from the nucleus b. shape of the orbital c. orientation in space (x, y, z) d. direction of electron spin (clockwise, counter-...
Consequences of quantum-mechanical phenomena in SOI devices with very thin semiconductor layers and ultrathin gate oxides are theoretically considered. The eect of quantization of electron energy in the very thin semiconductor layer in a double-gate SOI transistor on the drain current and phonon ...

Theelectron cloudis like a 3D graph that shows the chance of finding the electron in a location in space. Quantum mechanics also introduces the use oforbital quantum numbersto determine the energy level of an electron. In theBohr model, it is equivalent to how high the orbit is above the ...
Various theoretical models have been proposed through mechanical aging experiments. Kuhn et al. [30] defined the rheological energy density model and mechanical dissipation function to study mechanical aging, introducing the concept of entropy in mechanical degradation. Moore et al. [31] raised that ...
MOLECULAR-MECHANICSMost quantum mechanical studies of triterpene synthesis have been done on small models. We calculated mPW1PW91/6-311+G(2d,p)//B3LYP/6-31G* energies for many C30H51O+ intermediates to establish the first comprehensive energy profiles for the cationic cyclization of oxidosqualene...
