1. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation
Sammanfattning : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. LÄS MER
2. Katalogen – nyckeln till museernas kunskap? : Om dokumentation och kunskapskultur i museer
