Conserver la couleur des spécimens botaniques en fluide : Evaluation de méthodes de préservation de la chlorophylle et des tannins

Latty, Joane

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2021.

This master thesis is part of the LIQUOR project, of the cultural heritage conservation research unit of the University of Applied Science Arc in Neuchâtel (Switzerland). This project focuses on the conservation of plants in fluid in the context of heritage, to establish recommendations in this regard. The present work deals more specifically with the question of the discoloration of the green...

The structural colors of photonic glasses

Schertel, Lukas ; Siedentop, Lukas ; Meijer, Janne-Mieke ; Keim, Peter ; Aegerter, Christof M. ; Aubry, Geoffroy J. ; Maret, Georg

In: Advanced Optical Materials, 2019, p. 1900442

The color of materials usually originates from a combination of wavelength‐dependent absorption and scattering. Controlling the color without the use of absorbing dyes is of practical interest, not only because of undesired bleaching properties of dyes but also regarding minimization of environmental and health issues. Color control without dyes can be achieved by tuning the material's...

When black and white make green: the surprising interplay of structure and pigments

Sai, Tianqi ; Wilts, Bodo D. ; Sicher, Alba ; Steiner, Ullrich ; Scheffold, Frank ; Dufresne, Eric R.

In: CHIMIA International Journal for Chemistry, 2019, vol. 73, no. 1, p. 47–50

The natural world is teeming with color, which originates either from the wavelength- dependent absorp- tion of light by pigments or from scattering from nanoscale structures, or both. While the latter ' structural color ' has been a topic of intense study in recent years, the most vibrant colors in nature involve contributions from both structure and pigment. The study of structure–pigment...

Evaluation of extracellular vesicle function during malaria infection

Andrea Hernández-Castañeda, María ; Mbagwu, Smart Ikechukwu ; Babatunde, Kehinde Adebayo ; Walch, Michael ; Filgueira, Luis ; Mantel, Pierre-Yves

In: JoVE (Journal of Visualized Experiments), 2018, no. 132, p. e57067

Malaria is a life-threatening disease caused by Plasmodium parasites, with P. falciparum being the most prevalent on the African continent and responsible for most malaria-related deaths globally. Several factors including parasite sequestration in tissues, vascular dysfunction, and inflammatory responses influence the evolution of the disease in malaria-infected people. P. falciparum-infected...
