Whether it be foamed aluminium in the A-pillar of a passenger car, Ytong autoclaved aerated concrete, Elastolit PU rigid foam or Semperform EPDM window profile – whatever the class of materials, there will inevitably be foamed versions. Some of these are new while others have been established for decades, and they are used in a wide range of industrial and consumeroriented applications. Defined...

We introduce a new dynamic light scattering method, termed photon correlation imaging, which enables us to resolve the dynamics of soft matter in space and time. We demonstrate photon correlation imaging by investigating the slow dynamics of a quasi-two-dimensional coarsening foam made of highly packed, deformable bubbles and a rigid gel network formed by dilute, attractive colloidal particles....

Many wounds heal slowly and are difficult to manage. Therefore Negative Pressure Wound Therapy (NPWT) was developed where polymer foams are applied and a defined negative pressure removes wound fluid, reduces bacterial burden and increases the formation of granulation tissue. Although NPWT is used successfully, its mechanisms are not well understood. In particular, different NPWT dressings were...
