electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward (c3h4) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of methylacetylene (c3h4) the pristine nanotubes is a bout -1.78kcal/mol. but when nanotube have been doped with si and al atomes, the adsorption energy of methylacetyle...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward hydroquinone (c6h4(oh)2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g(d) level, and it was found that the adsorption energy (ead) of hydroquinone on the pristine nanotube is a bout -7.77kcal/mol. but when nanotubes have been doped with si and al atomes, the adsorption energy of hy...
abstract: electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward ethyl acetylene (c4h6) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of ethyl acetylene the pristine nanotubes is about -1.60kcal/mol. but when nanotube has been doped with si and al atoms, the adsorption energy ...
Chemical stabilities of six low-energy isomers of C24 derived from global-minimum search are investigated. The six isomers include one classical fullerene (isomer 1) whose cage is composed of only five- and six-membered rings (56-MRs), three nonclassical fullerene structures whose cages contain at least one four-membered ring (4-MR), one plate, and one monocyclic ring. Chemical and electronic p...
electrical sensitivity of a beryllium oxide nanotube (beont) was examined toward (c4h5n) molecule by using density functional theory (dft) calculations at the b3lyp/6-31(d) level, and it was found that the adsorption energy (ead) of pyrrole on the pristine nanotubes is a bout -48.58kcal/mol. but when nanotubes has been doped with s and p atomes , the adsorption energy changed. calculation sho...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...
رانیتیدین در گروهی از داروها به نام مسدودکنندههای h2 قرار دارد. این دارو میزان ترشح اسید در معده را کاهش میدهد و برای جلوگیری از سوءهاضمه، رفلکس اسید معده، زخم معده و سوزش معده مصرف میشود. در این مطالعه، پایداری توتومریهای رانیتیدین، اطلاعات ساختاری، اوربیتالهای homo و lumo (انرژیها و شکلها)، ??homo-lumo gap، نمودارها و دادههای uv-vis، ممانهای دوقطبی، بارهای مولیکن، ثابتهای تعادل و پ...
As cancer is the top killer diseases in the world, the scientists and researchers have been searching the new drugs and remedy methods. Most of the anticancer drugs are organic compounds which were approved by the FDA while metallodrugs are very rare. In the present time, some palladium and rhodium complexes are going to use as anticancer molecules. The palladium (II) complex has higher antican...
A dodecazinc silicotungstate K(20)Na(2)[Zn(6)(OH)(7)(H(2)O)(Si(2)W(18)O(66))](2)·34H(2)O (1) has been synthesized and characterized by X-ray crystallography, elemental analysis, infrared, UV-vis spectroscopy, cyclic voltammetry, acid-base titration, and DFT calculations. The twelve zinc atoms between the two [Si(2)W(18)O(66)](16-) frameworks make this complex more stable hydrolytically than the...
