conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of         on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

Quantum chromodynamics (QCD) describes how mass is created at the quark level. This mechanism special, because binding of quarks does not result in a loss or release energy, as case nuclear defect. Rather, by quarks. To achieve this binding, energy must be expended. At same time, however, are firmly bound to each other. Several authors have shown that masses elementary particles determined mean...

allopurinol, the xanthine oxidase inhibitor, is the only drug available for the treatment of gout. we examined the xanthine oxidase inhibitory activity of some commercially available flavonoids such asepigallocatechin, acacatechin, myricetin, naringenin, daidzein and glycitein by virtual screening and in-vitro studies. the interacting residues within the complex model and their contact types we...

the binding energy and thermodynamic parameters of cis- platinum di ammino chlorine (cis-[pt(nh3)2cl]+) and trans- platinum di ammino chlorine (trans- [pt(nh3)2cl]+) complexes withguanine has been studied by density functional theory (dft) calculations in water. the bindingenergies (ebin) of cis- and trans-[pt(nh3)2clg]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. the b...
