Summary of "Enhanced single-chain magnet behavior via anisotropic exchange in a cyano-bridged Mo(III)-Mn(II) chain."

Anisotropic magnetic exchange is of great value for the design of high performance molecular nanomagnets. In the present work, enhanced single-chain magnet (SCM) behavior is observed for a Mo III -Mn II chain that exhibits anisotropic magnetic exchange. Self-assembly of the pentagonal bipyramidal [Mo(CN) 7 ] 4- anion and the Mn II unit with a tridentate ligand results in a neutral double zigzag 2,4-ribbon structure which exhibits SCM behavior with a high relaxation barrier of 178(4) K. Open magnetic hysteresis loops are observed below 5.2 K, with a coercive field of 1.5 T at 2 K. Interestingly, this SCM can be considered to be a result of a step-by-step process based on our previously reported Mn 2 Mo single-molecule magnets (SMMs).

Medical and Biotech [MESH] Definitions

Proteins synthesized as a single chain of ~150 kDa with 35% sequence identity to TETANUS TOXIN that is cleaved to a light and a heavy chain that are linked by a single disulfide bond. They have neuro-, entero-, and hemotoxic properties, are immunogenic, and include the most potent poisons known. The most commonly used apparently blocks release of ACETYLCHOLINE at cholinergic SYNAPSES.

Protein synthesized by CLOSTRIDIUM TETANI as a single chain of ~150 kDa with 35% sequence identity to BOTULINUM TOXIN that is cleaved to a light and a heavy chain that are linked by a single disulfide bond. Tetanolysin is the hemolytic and tetanospasmin is the neurotoxic principle. The toxin causes disruption of the inhibitory mechanisms of the CNS, thus permitting uncontrolled nervous activity, leading to fatal CONVULSIONS.

A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle.

High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ION EXCHANGE) with either cations or anions.

People who engage in occupational sexual behavior in exchange for economic rewards or other extrinsic considerations.
