The two isomeric forms of this chemical exhibit distinct surface behaviors. This increases the efficiency of the perovskite cell by lowering the voltage mismatch. The tandem solar cell ...

Photochromism is a phenomenon described as a reversible conversion of a chemical species between two isomeric forms, induced by the absorption of electromagnetic radiation, which results in color ...

In nature vitamin E is present under one isomeric form, RRR α-tocopherol; when α-tocopherol is synthesized chemically, a racemic mixture of 8 possible isomers of α-tocopherol in equimolar ...
