Vanadium incorporation from aqueous NH4VO3 solution into siliceous Beta zeolite determined by NMR with formation of V-single site zeolite catalysts for application in SCR of NO

Rafal Baran, Yannick Millot, Frederic Averseng, Stanislaw Dzwigaj

The speciation of vanadium in initial aqueous NH4VO3 solutions as a function of pH and concentration, in supernatant and in wet solids were investigated by 51V static and MAS NMR. Two series of VSiBeta zeolite catalysts were prepared by a two-step postsynthesis procedure at pH = 2.5 and 6. 51V…

TiO2-Copper on smart textiles in a prototype plug flow reactor for enhanced photocatalytic removal of contaminants in fruit storage environments

Sarra Karoui, Amine Aymen Assadi, Nabisab Mujawar Mubarak, Abdeltif Amrane

The photocatalysis technique was chosen for its non-toxicity and high efficiency in combating indoor air pollution caused by volatile organic compounds (VOCs) and microorganisms. This paper investigates and discusses the simultaneous gas-phase removal of Ethyl acetate (EA) and Escherichia coli (E.…

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-…

Framework Stabilization of Ge-Rich Zeolites via Postsynthesis Alumination

Ff Gao, M Jaber, K Bozhilov, A Vicente, Christian Fernandez, V Valtchev

The use of organic structure directing agents in zeolite syntheses has dramatically extended the number of zeolite structure types during the past decades. However, for about 20% of all known zeolite structure types, the necessary postsynthesis elimination of organic templates by high-temperature…

Silk foams with metallic nanoparticles as scaffolds for soft tissue regeneration

Claire de Lartigue, Cristina Belda Marín, Vincent Fitzpatrick, Antonella Esposito, Sandra Casale, Jessem Landoulsi, Erwan Guénin, Christophe Egles

Tissue regeneration can be achieved by providing endogenous cells with a biomaterial scaffold that supports their adhesion and proliferation, as well as the synthesis and deposition of an extracellular matrix (ECM). In this work, silk fibroin protein foams were formed by lyophilization to generate…

Development of novel anti-Kv 11.1 antibody-conjugated PEG-TiO2 nanoparticles for targeting pancreatic ductal adenocarcinoma cells

Angelica Sette, Jolanda Spadavecchia, Jessem Landoulsi, Sandra Casale, Bernard Haye, Olivia Crociani, Annarosa Arcangeli

Titanium dioxide (TiO2) has been widely used in many nanotechnology areas including nanomedicine, where it could be proposed for the photodynamic and sonodynamic cancer therapies. However, TiO2 nanoformulations have been shown to be toxic for living cells. In this article, we report the development…

Al-Mn-silicate nanobubbles phase as an intermediate in zeolite formation

Amal Bejar, Semy Ben Chaabene, Maguy Jaber, Jean-François Lambert, Latifa Bergaoui

Manganese (II) carbonate, silicic acid and aluminum nitrate were treated hydrothermally at different temperatures (120–210°C) and for different durations (6–72 h) in an aqueous basic medium. Different compositions of starting mixtures were used. The synthetized materials were characterized by…

Impact of nontronite on the evolution of organic molecules at the surface of Mars

Patrice Coll, Olivier Poch, Maguy Jaber, Jean-François Lambert, Thomas Georgelin, Cyril Szopa, Fabien Stalport

Several evidences suggest that early Mars offered favorable conditions for long-term sustaining water. As a consequence, we can assume that in those days, endogenous chemical processes, or even primitive life, may have produced organic matter on Mars. Moreover, exogenous delivery from small bodies…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…
