Volume 42, Number 1
The advantages of in-house nitrogen generation are highlighted in the January issue, which discusses a nitrogen generator system with a hollow-fiber membrane that allows oxygen and water to permeate the membrane. An article on thermosets describes the role of time temperature tranformation in the curing process.
