Palaeontology, Volume 66, Issue 4, July/August 2023., 2023 Abstract Konservat‐Lagerstätten, such as the Toarcian (Early Jurassic) Posidonia Shale of southwestern Germany, are renowned for their spectacular fossils. Ichthyosaur skeletons recovered from this formation are frequently associated with soft tissues; however, the preserved material ranges from three‐dimensional, predominantly phosphatized structures ...

An overview of recent advances in polymer composites with improved UV‐shielding properties
Journal of Applied Polymer Science, Volume 140, Issue 14, April 10, 2023., 2023 Abstract Owing to their competitive price, ease of processability, and rust resistance, polymers are the most extensively used materials in everyday life. However, consistent exposure to ultraviolet (UV) radiation can lead to the degradation and discoloration of polymeric materials.

Traffic, Volume 23, Issue 6, Page 331-345, June 2022., 2022 We investigated the endocytic route followed by melanocores and melanosomes during internalization by keratinocytes. Depletion of critical proteins involved in actin‐dependent uptake mechanisms, together with inhibition of Rac1‐dependent signaling pathways or macropinocytosis suggest that melanocores are internalized by phagocytosis, whereas ...

Chemistry – A European Journal, Volume 27, Issue 66, Page 16309-16319, November 25, 2021., 2021 Melanin‐like materials can be easily prepared from simple precursors upon controlled oxidation/polymerization. In the resulting system, species with different structure and morphology coexist and interact. The overall photophysical and photochemical properties depend in part on the nature of the chromophores formed but also, to a large extent, on the ...
