Atoms are the fundamental unit of matter which makes up the different chemical elements. Atoms are made up of three main subatomic particles, namely: protons, electrons, and neutrons. The atomic theory is the scientific theory that aims to explain the structure, and function of atoms. Ma...
As we have seen, the formation of a homogeneous solution results from intimate mixing of the atoms. These atoms are located in space, on the crystalline sites for solids and inside a certain volume for liquids. Their distribution over these positions or at a location in the volume is random...
According to conventional understanding, the short-range order (SRO) of the nearest atoms dictates the metallization range order (MRO). We propose incorporating a top-down approach, in which global collective forces instigate liquid density waves, alongside the existing bottom-up approach commencing ...
It can also occur at a molecular level, due to changes in the orientation of electrically polar molecules in response to an applied field, or through bending & stretching of the bonds between atoms within a molecule, very much like the material in a mechanical spring is bent or stretched. P...

Ordinary hyaluronic acid has a linear structure. Basically, it's a series of atoms that form an almost straight line. At high concentrations, the linear molecules of hyaluronic acid come together to form what's known as a cross-linked structure. ...
Fig. 5: Mean square displacement (MSD) of atoms in the EDDA system during curing. The figure demonstrates a separation of the network into two phases with respect to thermal fluctuations. On average, the MSD of all atoms decreases with curing, however, the atoms that eventually join the larg...
Non-ionizing electromagnetic radiation is a type of energy that cannot knock electrons out of atoms. This type of radiation includes relatively harmless frequencies such as: Microwaves Radio waves Infrared waves Visible light While this type of radiation is not powerful enough to ionize atoms or mole...
Aromaticity is a vital concept that governs the electronic properties of π-conjugated organic molecules and has long been restricted to 2D systems. The aromaticity in 3D π-conjugated molecules has been rarely studied. Here we report a fully conjugated
c) Exchange of atoms. The apparent thermal contraction or expansion of the coordination shells is the result of at least two effects: (i) normal thermal expansion due to anharmonic thermal vibrations, and (ii) exchanges of atoms of different sizes. The atoms in the first nearest-neighbour...
