Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

FlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Impact of tomato variety and homogenization pressure on in vitro lipid digestion and lycopene bioaccessibility in tomato emulsions

Food Biomacromolecules, EarlyView.
Tomato variety and processing impact lycopene bioaccessibility. Tomato emulsions with high pectin content decreased the in vitro lipid digestion and negatively affected lycopene bioaccessibility. High pressure homogenization may enhance the release of lycopene into emulsion oil droplets, but it may also reduce the transfer of lycopene into the micellar
