WebSep 28, 2024 · We present a systematic density functional theory study to determine the electronic structure of bending 2H-MoS2 layers up to 75° using information from in-situ nanoindentation TEM observations. The results from HOMO/LUMO and density of states plots indicate a metallic transition from the typical semiconducting phase, near Fermi … WebNov 13, 1997 · Interaction of Watson−Crick adenine−thymine (AT) and guanine−cytosine (GC) base pairs with various metal (M) cations (Mg2+, ..., Hg2+) were studied by nonempirical ab initio methods with inclusion of correlation energy. Cations were allowed to interact with the N7 nitrogen of adenine and the N7 and O6 atoms of guanine. All of the …
WebIn this work we studied three dyes which are proposed for potential photovoltaic applications and named Dye7, Dye7-2t and Dye7-3t. The Density Functional Theory (DFT) was utilized, using the M05-2X hybrid meta-GGA functional and the 6–31+G(d,p) basis set. This level of calculation was used to find the optimized molecular structure and to predict the main … WebThus, we can regard the bases as side chains extending out from the backbone. Returning to homo-DNA, Eschenmoser's group has synthesized an octamer using homo-nucleotides. The sequence of bases in the 8-mer is such that two strands are self-complementary. Therefore, in principle, the two strands can form a double helix through Watson-Crick …
