In this research, the structure, quantum and NQR (Nuclear quadrupole resonance)parameters of F2 gas adsorption on the pristine and 3C-doped (4,4) armchair models of boron phosphide nanotubes (BPNTs) have been investigated in the framework of density functional theory. For this purpose, at the first step, four models for F2 adsorption on the inner and outer surfaces of pristine and 3C-doped BPNT...
In present research, the electrical, structural, quantum and Nuclear Magnetic Resonance (NMR) parameters of interaction of N2O gas on the B and P sites of pristine, Ga-, Si- and SiGa-doped (4,4) armchair models of boron phosphide nanotubes (BPNTs) are investigated by using density functional theory (DFT). For this purpose, seven models for adsorption of N2O gas on the exterior surfaces of BPN...
abstract the structural and electrostatic properties of the single-walled two representative (8, 0) zigzag and (4, 4) armchair models of pristine and gaas-doped on boron phosphide nanotubes (bpnts) was investigated by calculating the nuclear magnetic resonance tensors and with performing the density function theory. the geometrical structures of all representative pristine and gaas-doped models...
در این تحقیق، ساختار پارامترهای کوانتومی و nqr فرایند جذب گاز 2f بر روی مدل های خالص و جایگزین شده با سه کربن نانو لوله بورن فسفید با استفاده از نظریه تابع چگالی بررسی شده است. برای این منظور در ابتدا چهار مدل برای جذب 2f بر روی سطح داخلی و خارجی حالت خالص و جایگزین شده با سه کربن را در نظر گرفته و سپس تمام ساختارها بهینه می شوند. ساختارهای بهینه شده برای محاسبه پارامترهای کوانتومی و nqrاستفاده...
in this research, the interactions of hcn gas with pristine, ga-, n- and gan-doped of boron phosphide nanotube (bpnts) were investigated by using density function theory (dft). the structure, electrical and nqr parameters, quantum descriptors involving energy gap, global hardness, global softness, electrophilicity, electronic chemical potential and electronegativity were calculated. the adsorpt...
