Room Temperature Hydrogen Sensor Based on Single-Electron Tunneling Between Palladium Nanoparticles
In this paper, we present the results of single-electron tunneling in two-dimensional (2D) hexagonal closed packed arrays of palladium nanoparticles. After inspecting the emergence of Coulomb blockade phenomena, we demonstrate the possibilities of using these arrays as a single-electron tunneling based hydrogen sensor. We assumed arrays of palladium nanoparticles with diameters of 3.5 and 6...
متن کاملDeuterium isotope effects and fractionation factors of hydrogen-bonded A:T base pairs of DNA.
Deuterium isotope effects and fractionation factors of N1.H3-N3 hydrogen bonded Watson-Crick A:T base pairs of two DNA dodecamers are presented here. Specifically, two-bond deuterium isotope effects on the chemical shifts of (13)C2 and (13)C4, (2)delta(13)C2 and (2)delta(13)C4, and equilibrium deuterium/protium fractionation factors of H3, Phi, were measured and seen to correlate with the chemi...

متن کاملStm Studies of Hydrogen-bonded Dna Base Aggregates Relevant for Biology
Hydrogen bonding between DNA bases is one of the main interactions that control the conformation and hence the biochemical function of nucleic acid molecules [1]. The exact physico-chemical nature of these bonds, and the importance of charge transfer contribution to the stabilization energy associated to hydrogen bonding in NA molecules have recently been the subject of an intense debate [2-4],...
متن کاملAccurate interaction energies of hydrogen-bonded nucleic acid base pairs.
Hydrogen-bonded nucleic acids base pairs substantially contribute to the structure and stability of nucleic acids. The study presents reference ab initio structures and interaction energies of selected base pairs with binding energies ranging from -5 to -47 kcal/mol. The molecular structures are obtained using the RI-MP2 (resolution of identity MP2) method with extended cc-pVTZ basis set of ato...
