STOCKHOLM (Reuters) -Scientists Moungi Bawendi, Louis Brus and Aleksey Ekimov won the 2023 Nobel Prize in Chemistry for their discovery of tiny clusters of atoms known as quantum dots, widely used ...
“I think one of the most exciting moments was when we were resurrecting the molecules in the laboratory using chemistry and then we were bringing them back to life for the first time.
In chemistry, hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergoes solvation. Hydration energy is one component in the quantitative analysis of solvation. It is a particular special case of water. [1] The value of hydration energies is one of the most challenging aspects of structural ...

In chemistry and particularly biochemistry, an energy-rich species (usually energy-rich molecule) or high-energy species (usually high-energy molecule) is a chemical species which reacts, potentially with other species found in the environment, to release chemical energy. [citation needed] In particular, the term is often used for:
In the field of computational chemistry, energy minimization (also called energy optimization, geometry minimization, or geometry optimization) is the process of finding an arrangement in space of a collection of atoms where, according to some computational model of chemical bonding, the net inter-atomic force on each atom is acceptably close to zero and the position on the potential energy ...
The year 1873, by many accounts, was a seminal point in the history of the development of the concept of the "molecule". In this year, the renowned Scottish physicist James Clerk Maxwell published his famous thirteen page article 'Molecules' in the September issue of Nature. [15] In the opening section to this article, Maxwell clearly states:
The approximate energy spacing of these levels can be estimated by treating each nucleus as a quantum harmonic oscillator in the potential produced by the molecule, and comparing its associated frequency to that of an electron experiencing the same potential. The result is an energy spacing about 100× smaller than that for electronic levels.
