A High-Pressure, High-Temperature Flow Reactor Simulating the Hadean Earth Environment, with Application to the Pressure Dependence of the Cleavage of Avocado Viroid Hammerhead Ribozyme

Kunio Kawamura, Mari Ogawa, Noriko Konagaya, Yoshimi Maruoka, Jean-François Lambert, Louis M. P. Ter-Ovanessian, Jacques Vergne, Guy Hervé, Marie-Christine Maurel

The RNA world hypothesis suggests that chemical networks consisting of functional RNA molecules could have constructed a primitive life-like system leading a first living system. The chemical evolution scenario of RNA molecules should be consistent with the Hadean Earth environment. We have…

Chemically and Physically Pretreated Straw in Moderate Conditions: Poor Correlation between Biogas Production and Commonly Used Biomass Characterization

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Straw is a substantial agricultural by-product for biogas production. Hydrolysis of straw is found to be a rate-limiting step during its anaerobic digestion and could be enhanced by pretreatment. In this paper, the effect of various combinations of particle size reduction, autoclaving, and low-…

Effect of equal channel angular extrusion on wear and corrosion behavior of the orthopedic Ti-13Nb-13Zr alloy in simulated body fluid

K.S. Suresh, M. Geetha, C. Richard, Jessem Landoulsi, H. Ramasawmy, S. Suwas, R. Asokamani

We report investigations on the texture, corrosion and wear behavior of ultra-fine grained (UFG) Ti-13Nb-Zr alloy, processed by equal channel angular extrusion (ECAE) technique, for biomedical applications. The microstructure obtained was characterized by X-ray line profile analysis, scanning…

Ru complex and N, P-containing polymers confined within mesoporous hollow carbon spheres for hydrogenation of CO2 to formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

The development of reliable catalysts with both excellent activity and recyclability for carbon dioxide (CO2) hydrogenation is challenging. Herein, a ternary hybrid heterogeneous catalyst, involving mononuclear Ru complex, N, P-containing porous organic polymers (POPs), and mesoporous hollow carbon…

Bridging Hydroxyls on Anatase TiO$_2$ (101) by Water Dissociation in Oxygen Vacancies

Immad M Nadeem, George T Harrison, Axel Wilson, Chi L Pang, Jörg Zegenhagen, Geoff Thornton

Titanium dioxide is a promising candidate for photocatalytic H$_2$ fuel production, and understanding water splitting on TiO$_2$ surfaces is vital toward explaining and improving the generation of H$_2$. In this work, we electron irradiate anatase TiO$_2$ (101) at room temperature to create…

Exploring the Reactivity of Framework Vanadium, Niobium, and Tantalum Sites in Zeolitic Materials Using DFT Reactivity Descriptors

Frederik Tielens

The acid-base properties of zeolites with group 5 transition metal framework sites are investigated, and a first step into the understanding of their acid/base and redox properties is undertaken using DFT reactivity descriptors. It is evidenced, using socialite as model system, that zeolites with…
