Supercapacitors may have either symmetric or asymmetric electrodes. Synapses may be described as symmetric or asymmetric. These may include symmetric keys or asymmetric keys. Multiple examples of symmetric and asymmetric competition also exist for animals. This is true for both asymmetric and symmetric TSPs. Rorschach experimented with both asymmetric and symmetric images before finally opting for the latter. Chiral ligands are used in homogeneous catalysis, such as asymmetric hydrogenation. Chiral Schiff bases were one of the first ligands used for asymmetric catalysis. Repetition of an asymmetric link generates a helix. In organic chemistry, menthol is used as a chiral auxiliary in asymmetric synthesis. Iridium complexes are being investigated as catalysts for asymmetric hydrogenation. Credentials are stored locally and protected using asymmetric encryption. Organic chemists capitalize on the rigidity resulting from allylic strain for use in asymmetric reactions. While this term is similar to terrorism and asymmetric warfare, it is much narrower. There are two different viewpoints on the relationship between asymmetric warfare and terrorism.
