What is Manganese-mediated coupling reactions?

Alpha-substitution reactions occur at the position next to the carbonyl group,the α-position, and involve the substitution of an α hydrogen atomby an electrophile, E, through either an enol or enolate...

In physics, a gravitational coupling constant is a constant characterizing the gravitational attraction between a given pair of elementary particles. The electron mass is typically used, and the associated constant...

Wouthuysen–Field coupling, or the Wouthuysen–Field effect, is a mechanism that couples the excitation temperature, also called the spin temperature, of neutral hydrogen to Lyman-alpha radiation. This coupling plays a role...

A coupling nut, also known as extension nut, is a threaded fastener for joining two male threads, most commonly a threaded rod, but also pipes. The outside of the fastener...

A jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control applications. It is designed to transmit torque while damping system...

The Geislinger coupling is an all-metal coupling for rotating shafts. It is elastic in torsion, allowing it to absorb torsional vibration. Unlike some other coupling types, it is not intended...

The electromechanical coupling coefficient is a numerical measure of the conversion efficiency between electrical and acoustic energy in piezoelectric materials. Qualitatively the electromechanical coupling coefficient, k, can be described as:
