Gas-separation membranes loaded with porous aromatic frameworks that improve with age.

Porosity loss, also known as physical aging, in glassy polymers hampers their long term use in gas separations. Unprecedented interactions of porous aromatic frameworks (PAFs) with these polymers offer the potential to control and exploit physical aging for drastically enhanced separation efficiency. PAF-1 is used in the archetypal polymer of intrinsic microporosity (PIM), PIM-1, to achieve thr...

H 2 -cooling of Primordial Gas Triggered by Uv Irradiation

We investigate the formation of molecular hydrogen (H 2) in a primordial H+He gas cloud irradiated by a power-law UV ux. We nd that at high densities (> 1 cm 3) and low temperatures (< 10 4 K), the background radiation enhances the formation of H 2 and results in molecular cooling dominating over photoionization heating. This process could accelerate the collapse and fragmentation of dense obje...

Local deformation behavior of surface porous polyether-ether-ketone.

Surface porous polyether-ether-ketone has the ability to maintain the tensile monotonic and cyclic strength necessary for many load bearing orthopedic applications while providing a surface that facilitates bone ingrowth; however, the relevant deformation behavior of the pore architecture in response to various loading conditions is not yet fully characterized or understood. The focus of this s...

Optimisation of UV irradiation as a binding site conserving method for crosslinking collagen-based scaffolds

Short wavelength (λ = 254 nm) UV irradiation was evaluated over a range of intensities (0.06 to 0.96 J/cm(2)) as a means of cross-linking collagen- and gelatin-based scaffolds, to tailor their material characteristics whilst retaining biological functionality. Zero-link carbodiimide treatments are commonly applied to collagen-based materials, forming cross-links from carboxylate anions (for exa...
