This article describes a standard method to get a three-dimensional (3D) reconstruction of biological macromolecules using negative staining electron microscopy (EM). In this protocol, we explain how to get the 3D structure of the Saccharomyces cerevisiae exosome complex at medium resolution using the random conical tilt reconstruction method...

Nuclear Stability

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Radioactivity and Nuclear Equations

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.
A nuclide of an element has a specific number of protons and...

Area of Science:

  • Quantum Chemistry
  • Molecular Dynamics
  • Theoretical Chemistry

Background:

  • Combined electronic-nuclear wave packet motion influences molecular dynamics.
  • Conical intersections (CIs) are critical regions in potential energy surfaces for non-adiabatic transitions.

Purpose of the Study:

  • Investigate temporal changes in probability flux densities near CIs.
  • Analyze electronic and nuclear flux behavior during wave packet motion.

Main Methods:

  • Utilized a two-dimensional model to simulate wave packet dynamics.
  • Examined probability flux densities in the vicinity of a conical intersection.

Main Results:

  • Electronic flux density is nearly time-independent during efficient population transfer, while nuclear flux is not.
  • In cases with nuclear wave packet bifurcation around a CI, electronic flux shows constant directional dynamics.

Conclusions:

  • The study reveals distinct behaviors of electronic and nuclear flux densities near conical intersections.
  • Geometrical phase effects are observable in nuclear flux dynamics, differing from Born-Oppenheimer calculations.
