DID YOU KNOW?
Nappies are full of polymers. They are made of polyethylene, use elastic made from natural rubber to keep them from leaking but most importantly they're packed with polyacrylic acid, a member of the acrylate family of polymers that absorb lots of moisture.


Physics & Astronomy

Liquids, colloids, polymers, foams, gels, membranes, biological materials and therefore life itself are just a handful of examples of soft matter.

With many internal degrees of freedom with weak interactions between the structural components, soft matter sensitive to the environment enabling functional materials to be created.

Soft matter can be found throughout industrial and technological applications. Whether it’s packaging, adhesives, detergents, cosmetics, medicines, fuels, rubber tyres, or paints, soft matter physics is central and essential to understanding, designing and optimising these products.

Direct conversion of rheological compliance measurements into storage and loss moduli

The procedure that has become established, for obtaining frequency-dependent dynamic moduli from non-oscillatory rheometry, is either to fit the experimental data to a particular model (e.g. the generalized Maxwell model), or to use approximate Laplace transformation of the compliance, and subsequently transform from a Laplace to a Fourier description.
