The old adage of like dissolves like comes from understanding the polar or non-polar character of molecules. A molecules polarity rises from the electronegativity of the atoms in the molecule and the spatial positioning of the atoms. Symmetrical molecules are non-polar but as the symmetry of the...

1a). Here, we manipulate single dipolar molecules and obtain unidirectional rotation on demand, and thus deterministic behavior. From these precision manipulation experiments, the electric field-induced motion can be mapped and used to determine the internal dipole moment of a single molecule. Fig. ...
The regulation of cellular shape and tension by curvatures at various length scales activates specific mechanotransduction pathways that synergistically determine downstream cellular functions. Changes in the balance of cellular forces required to adapt to curved environments can have dramatic consequences, prom...
Lewis Structures: Lewis structures are pictoral diagrams of molecules used to demonstrate the arrangement of covalent bonds between atoms. They are determined by trying to satisfy the octet of each atom whilst ensuring that the total number of valence electrons in the molecule overall stays constant...
They are commonly used to differentiate the types of compounds, and they also appear as different group types, such as alcohol, amine, ketone, and carboxylic acid. When functional groups attach to a carbon skeleton, they affect the properties of the compound, such as its polarity, re...
The polarity of a bond is determined by a periodic concept called electronegativity. Electronegativity is an expression of an atom's tendency to attract electrons in a chemical bond. In order to determine the polarity of a bond, you must find the difference in the electronegativies of the atom...
In covalent bonds within molecules, the individual atoms contained share electrons to make the molecule stable. Oftentimes, these bonds result in one of the atoms, which has a stronger attractive force than the others, bringing the electrons toward itsel
