Light-adapted charge-separated state of photosystem II: structural and functional dynamics of the closed reaction center

Melinda Magyar, Alberto Mezzetti, Parveen Akhtar, Qingjun Zhu, Yanan Xiao, Guangye Han, Stefano Santabarbara, Jian-Ren Shen, Petar Lambrev, Győző Garab, Gábor Sipka

Photosystem II (PSII) uses solar energy to oxidize water and delivers electrons for life on Earth. The photochemical reaction center of PSII is known to possess two stationary states. In the open state (PSIIO), the absorption of a single photon triggers electron-transfer steps, which convert PSII…

Thermal Behavior of d -Ribose Adsorbed on Silica: Effect of Inorganic Salt Coadsorption and Significance for Prebiotic Chemistry

Mariame Akouche, Maguy Jaber, Emilie-Laure Zins, Marie-Christine Maurel, Jean-Francois Lambert, Thomas Georgelin

Understanding ribose reactivity is a crucial step in the “RNA world” scenario because this molecule is a component of all extant nucleotides that make up RNA. In solution, ribose is unstable and susceptible to thermal destruction. We examined how ribose behaves upon thermal activation when adsorbed…

Magnetic Traits in CoO‐Core@CoFe 2 O 4 ‐shell Like Nanoparticles

Nancy Flores-Martinez, Margot Roemer, Sarra Gam-Derouich, Patricia Beaunier, David Habrovsky, Souad Ammar

Antiferromagnetic (AF) CoO pseudo-single crystals 125±20 nm in diameter were prepared by forced hydrolysis in polyol and used as seeds to grow a poly- and nano-crystalline (5 nm in diameter) ferrimagnetic (F) CoFe2O4 shell. Transmission electron microscopy (TEM) showed a certain epitaxy between the…

Investigation of the plate-impact method as a precursor of physical phenomena and chemical processes, L'étude de la méthode de l'impact par plaque comme précurseur des phénomènes physiques et des processus chimiques

Maya Mounir Daou

This manuscript aims at characterizing a new device based on a plate impact on a liquid surface to generate cavitation and evaluate its potential to induce chemical reactions. The device is composed of a reactor containing a liquid that a piston hits due to pressure difference. This impact…, Ce manuscrit a pour but d'étudier un nouveau dispositif générateur de cavitation dont le potentiel favorable à l'intensification de réactions chimiques est évalué. Ce dispositif est constitué d'une plaque mobile qui frappe un liquide contenu dans un réacteur. L'impact génère une…
