Abstract: The present disclosure generally relates to baseboards and methods of making and using baseboards. Some baseboards described herein include a foam body having a first major surface opposite and separated from a second major surface and a top surface opposite and separated from a bottom surface; the foam body including a foam having a density of between about 20 kg/m3 and about 100 kg/m3; a rigid coating on one of the first or second major surfaces of the foam body; the rigid coating having a modulus of elasticity of between about 1000 MPa and about 10,000 MPa and a thickness of between about 200 to about 1000 micrometers; and optionally an adhesive layer on the other of the first or second major surfaces of the foam body. In some embodiments, the baseboards have a modulus of elasticity of at least 100 MPa. This ensures that they are sufficiently rigid while remaining hand-cuttable.

Abstract: A hollow-fiber membrane. The hollow-fiber membrane is made from a polymeric blend comprising an aromatic sulfone polymer and polyoxazoline; wherein the hollow-fiber membrane comprises an inner surface facing towards its lumen, an outer surface facing outwards and an intermediate wall having a wall thickness; wherein the hollow-fiber membrane is an integrally asymmetric, permeable hollow-fiber membrane.

Abstract: An asymmetric membrane. The asymmetric membrane includes a membrane wall with a first and a second porous surface and an interior situated between the surfaces; a first asymmetrical region towards the first surface; a second asymmetrical region towards the second surface; wherein the asymmetric membrane is made from a polymeric blend comprising an aromatic sulfone polymer and poly (2-oxazoline); and wherein the asymmetric membrane is in the form of a flat sheet.
