THEORETICAL STUDIES OF CHANGES IN PROPERTIES OF 5-FLUORO-2-DEOXYURIDINE (FUDR) ANTICANCER DRUG BY ADSORPTION ON BORON NITRIDE NANOTUBE (5, 5-11)
Background & Aims: Drugs are highly active due to their many functional groups and can be easily destroyed by stomach acid and excreted before reaching target tissue. Thus, by encapsulating, a sheath is placed around drug to reduce reactivity of the drug due to stereo electronic resonance with nanotube and consequently drug stays longer in body. As a result, you can consume a smaller dose of dr...
متن کاملBoron Sheets and Boron Nanotubes
Based on an ab initio study, we present a structure model for a broad boron sheet, which is the precursor of boron nanotubes. Furthermore we could show that, in contrast to the armchair types, zigzag boron nanotubes have no surface tension (strain energy). As result, we predict that boron nanotubes will exhibit a chirality dependent stability, something that is unique among all nanotubular mate...
متن کاملLight Element Abundance Patterns in the Orion Association : I ) HST Observations of Boron in G - dwarfs
The boron abundances for two young solar-type members of the Orion association, BD -6 1250 and HD294297, are derived from HST STIS spectra of the B I transition at 2496.771 Å. The best-fit boron abundances for the target stars are 0.13 and 0.44 dex lower than the solar meteoritic value of log ǫ(B)=2.78. An anticorrelation of boron and oxygen is found for Orion when these results are added to pr...
متن کاملPiezoelectric effects in boron nitride nanotubes predicted by the atomistic finite element method and molecular mechanics.
We calculate the tensile and shear moduli of a series of boron nitride nanotubes and their piezoelectric response to applied loads. We compare in detail results from a simple molecular mechanics (MM) potential, the universal force field, with those from the atomistic finite element method (AFEM) using both Euler-Bernoulli and Timoshenko beam formulations. The MM energy minimisations are much mo...
