are composed of neutral molecules. The strengths of the attractive forces between the units present in different crystals vary widely, as indicated by the melting points of the crystals. Small symmetrical molecules (nonpolar molecules), such as H2, N2, O2, and F2, have weak attractive ...
Molecules in the liquid state cling to one another. When the liquid absorbs additional heat, the more energetic molecules break away from the liquid surface and go into the gaseous state—the most mobile state of matter. Gas molecules move at very high velocities and have high kinetic energy....
Ultrafast electron diffraction and time-resolved serial crystallography are the basis of the ongoing revolution in capturing at the atomic level of detail the structural dynamics of molecules. However, most experiments capture only the probability densit
The colloidal state refers to the condition where asphaltene molecules are peptized by resins in crude oil, leading to their mobility within the mixture. This state is crucial for stabilizing asphaltene molecules and preventing their precipitation. ...
Of the three states of matter, solids possess the most structural diversity. Whereas gases and liquids consist of discrete molecules that are randomly distributed due to thermal motion, solids consist of molecules, atoms, or ions that are statically positioned. To fully understand the properties of...
Stochastic Conformational Pumping: A Mechanism for Free-Energy Transduction by Molecules and the probability current from any other state i to state j is given as the sum of a steady-state current and a pumped current, I(ij)=I(ss)(... RD Astumian - 《Annual Review of Biophysics》 被引...
Writing in Physical Review Letters, the team concludes that the trapped molecules are “a new state of the water molecule” – one that is a blurry ring with six-fold rotational symmetry. Such a molecule, the team believes, would not have an electric-dipole moment. An unconfined water molecu...
A promising approach to preserving the photoswitching behaviour of organic photochromes in the solid state is to incorporate the molecules within a scaffold featuring precisely designed pores. This Review provides guidelines to identify porous scaffolds with the most promising performance in organic-based...
Stimulated by recent mass spectrometric observations, we have investigated several high-spin states of CO- to identify the observed anionic state. We follow a general construction principle for long-lived anionic states of small molecules: A possibly long-lived anionic state possesses several “equivale...
