Versatile Photofunctionalization of Carbon Nanotubes via [4 + 2] Cycloaddition: A Facile Route to Hybrid Nanomaterials

open access: yesSmall Science, EarlyView.
A [4 + 2] photocycloaddition of aryl cyclobutyl amines on carbon nanotubes is presented. A photocatalyst oxidizes the cyclic moiety to generate an active species trapped by the nanotube π‐cloud. The method functionalizes nanotubes of different characteristics and is tolerant to different functional groups decorating the amine.

Bicontinuous Interconnected Porous Biomaterials for Tissue Engineering and Regeneration

open access: yesSmall Science, EarlyView.
Solvent transfer‐induced phase separation transforms bioinert polyethylene glycol diacrylate into bioactive scaffolds featuring bicontinuous interconnected porosity, with negative Gaussian curvature, and unique topographical patterning. These attributes enable stem cell attachment, proliferation, and differentiation without basement membrane matrix ...

Holistic Microstructure Control Strategies in Photopolymerization‐Induced Phase Separation of Acrylate Systems

open access: yesSmall Structures, EarlyView.
A physics‐based phase‐field model and experimental validation are combined to simulate and analyze porous microstructures from photopolymerization‐induced phase separation processes, examining factors like polarity, light intensity, curing temperature, chain transfer agents, and substrates.

Hunting method affects cortisol levels in harvested mountain hares (Lepus timidus)

open access: yesWildlife Biology, EarlyView.
The direct effects of hunting on hunted individuals and populations have been well known for a long time. However, recently there has also been an increased focus on the indirect, non‐lethal effects of hunting. When approached by a possible threat such as a predator, the prey releases various stress hormones into the bloodstream.
