Polyethylene produced by a vanadium-based polymerization catalyst contains long-chain branching as determined by NMR and rheology, even though the polymer has very low levels of vinyl unsaturation. A new mechanism is proposed for the formation of the long-chain branching, which involves COH bond act
The accumulation of high levels of the ketocarotenoid astaxanthin by the green freshwater microalga Haematococcus pluvialis in response to extreme environmental conditions is a well recorded phenomenon. However, there is still considerable debate regarding the nature and possible interactions of the
