Life on Minerals: Binding Behaviors of Oligonucleotides on Zirconium Silicate and its Inhibitory Activity for the Self-Cleavage of Hammerhead Ribozyme

Kunio Kawamura, Jean-François Lambert, Louis Ter-Ovanessian, Jacques Vergne, Guy Hervé, Marie-Christine Maurel

The role of minerals in the chemical evolution of RNA molecules is an important issue when considering the early stage of the Hadean Earth. In particular, the interaction between functional ribozymes and ancient minerals under simulated primitive conditions is a recent research focus. We are…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…

PET waste as organic linker source for the sustainable preparation of MOF-derived methane dry reforming catalysts

Leila Karam, Arianna Miglio, Stefania Specchia, Nissrine El Hassan, Pascale Massiani, Julien Reboul

A catalyst made of Ni 0 nanoparticles highly dispersed on a lamellar alumina support was prepared by an environmentally-friendly route. The latter involved the synthesis of an aluminum-containing metalorganic framework (MOF) MIL-53(Al) in which the linkers were derived from the depolymerization of…

Plastic waste recycling via pyrolysis: A bibliometric survey and literature review

Sabino Armenise, Wong Syieluing, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Norzita Ngadi, Joaquín Rams, Marta Muñoz

Plastic materials have been crucial to the development of science, technology, and almost all aspects of modern progress since the mid-twentieth century. However, the increasingly unsustainable culture of plastic consumption and the accumulation of plastics in landfills, oceans, and broader…

Enzymatic Approach in Calcium Phosphate Biomineralization: A Contribution to Reconcile the Physicochemical with the Physiological View

Clément Guibert, Jessem Landoulsi

Biomineralization is the process by which organisms produce hard inorganic matter from soft tissues with outstanding control of mineral deposition in time and space. For this purpose, organisms deploy a sophisticated “toolkit” that has resulted in significant evolutionary innovations, for which…

Influence of the nature and environment of manganese in Mn-BEA zeolites on NO conversion in selective catalytic reduction with ammonia

Rafal Baran, L. Valentin, J.-M. Krafft, T. Grzybek, P. Glatzel, Stanislaw Dzwigaj

Manganese-containing BEA zeolites, MnxSiBEA (x = 1–4 wt %) and Mn(I.E.)AlBEA, were prepared by a two-step postsynthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…

Incorporation of Mo into the Vacant T-Atom Sites of the Framework of BEA Zeolite as Mononuclear Mo Evidenced by XRD and FTIR, NMR, EPR, and DR UV-Vis Spectroscopies

Rafal Baran, Frédéric Averseng, Yannick Millot, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A MoSiBEA zeolite has been prepared by a two-step postsynthesis procedure that consists of first creating the vacant T-atom sites with associated silanol groups by treatment of TEABEA zeolite with nitric acid and then incorporating Mo ions into the vacant T-atom sites by solid-state ion exchange at…

New routes of preparation of active and stable mesoporous Ni-alumina based catalysts for methane dry reforming and CO2 methanation, Nouvelles voies de préparation de catalyseurs actifs et stables à base de Ni-alumine mésoporeuse pour le reformage à sec du méthane et la méthanation du CO2

Leila Karam

Dry reforming of methane (DRM) is a process that converts CH4 and CO2 gases into syngas, a gaseous mixture of H2 and CO. Ni based catalysts proved to be suitable for the reaction due to their good activity, wider availability and lower cost than noble-based materials. However, these catalysts are…, Le reformage à sec du méthane (DRM) est un processus qui convertit simultanément CH4 et CO2 en un mélange gazeux de H2 et de CO appelé syngas. Les catalyseurs à base de Ni sont particulièrement prometteurs mais ils ne sont pas stables en raison du frittage du Ni et du dépôt de coke. Dans cette…
