Charge-density reduction promotes ribozyme activity in RNA–peptide coacervates via RNA fluidization and magnesium partitioning Abstract It has long been proposed that phase-separated compartments can provide a basis for the formation of cellular precursors in prebiotic environments. However, we know very ...
Voronoi deformation densityThe symmetry-decomposed Voronoi deformation density (VDD) charge analysis is an insightful and robust computational tool to aid the understanding of chemical bonding throughout all fields of chemistry. This method quantifies the atomic charge flow associated with chemical-bond ...
In subject area: Chemistry A Charge Density Wave (CDW) is a static modulation of conduction electrons driven by the Fermi surface, accompanied by a periodic lattice distortion that lowers the electronic energy of a solid. AI generated definition based on: Physical Metallurgy (Fifth Edition), 2014...
The electron density (ED,ρ(r)) is a quantum mechanical observable, that can be measured, for example, through scattering experiments, in particular X-ray diffraction from crystals. Although it can be directly calculated by Fourier summations of structure factors, the electron density is better o...
We find that the density of charged species in the spatial afterglow decays by orders of magnitude, which leads to a transition from ambipolar to free diffusion. These insights can be used to explain or predict experimental observations of phenomena, such as the charging of dust grains and the...
Oxide surfaces in water are typically hydroxylated. The surface charge density σ0 is thus a function of pH due to protonation or deprotonation of OH-groups. The point of zero charge (PZC) is the pH at which the surface charge density vanishes, see Fig. 3.5. At this point, preferred coag...
What is the meaning of polarity? Explain Coulomb's law. Define (a) a coulomb, (b) an electric current, (c) an ampere, and (d) a faraday. Why charge density is highest at the point? Giving examples, define molecular formulas as used in the study of molecules. ...
Explain how the direction of the arrow in the bond dipole symbol relates to the electron density and the partial charges. How do the interparticle forces in a solid influence the bulk physical properties of the solid? What is the purpose of ioni...
