In chemistry, molecules are said to be symmetrical when interchanging the orientation of the substituents produces an equivalent molecule. There are also symmetry elements where symmetry operations can be performed. These may include a point, plane, or axis of...

Symmetry Elements: Symmetry elements in chemistry are abstract concepts related to the symmetry operations of molecules. They are fundamental to the field of group theory, which is used in chemistry to describe the structures of molecules, their ene...
Only a 2D cross section (light blue) of the reactor needs to be modeled due to axial symmetry. The composition and temperature vary in the r and z directions. The cooling jacket temperature only varies in the z direction at the position r = R. Operating...

Accordingly, the book covers not only the 'inorganic' chemistry of the elements, but also analytical, theoretical, industrial, organometallic, bio-inorganic and other cognate areas of chemistry. The authors have broken with recent tradition in the teaching of their subject and adopted a new and hi...
Arrays of regularly spaced nucleosomes dominate chromatin and are often phased by alignment to reference sites like active promoters. How the distances between nucleosomes (spacing), and between phasing sites and nucleosomes are determined remains unclea
