An X-ray spectroscopy view on active sites: removing the obscuring silent majority (XRAYonACTIVE)

Date du début: 1 avr. 2014, Date de fin: 31 mars 2019,

One of the holy grails in catalytic research is the determination of the structure of the active site. Information on the catalytically active site is notoriously difficult to obtain as it concerns a small minority of states in a sea of other silent states. This silent majority of states obscures the action that takes place on the active states. Because the core hole localizes the final state, X-r ...

Supported Nanoparticles for Catalysis: Genesis and Dynamics in the Liquid Phase (NanoPartCat)

Date du début: 1 avr. 2014, Date de fin: 31 mars 2019,

Supported metal nanoparticles are used as catalysts to accelerate and steer chemical conversions to produce, e.g., transportation fuels, chemicals and medicines. Albeit of eminent importance, supported metal catalysts are almost exclusively synthesized in liquid-phase processes that are often considered ‘an art rather than a science’. Although recent results from our laboratory and others on the f ...

Near-Field Spectroscopic Imaging of the Assembly and Working of Nanosheets of Catalytic Porous Materials (NanoInspection)

Date du début: 1 avr. 2013, Date de fin: 31 mars 2018,

The pressing need for a more sustainable society has sparked intensive research efforts in search for novel materials with controlled structure, porosity and functionalities. Such porous materials may combine high catalytic activity and selectivity with a long-term stability in the conversion of renewable (e.g. biomass) and non-renewable feedstock when producing future transportation fuels and che ...

CAScade deoxygenation process using tailored nanoCATalysts for the production of BiofuELs from lignocellullosic biomass (CASCATBEL)

Date du début: 1 nov. 2013, Date de fin: 31 oct. 2017,

The present project is aimed to the development of a multi-step process for the production of second-generation biofuels from lignocellulosic biomass in a cost-efficient way through the use of tailored nanostructured catalysts. The proposed process is based on the cascade combination of three catalytic transformations: catalytic pyrolysis, intermediate deoxygenation and hydrodeoxygenation. The seq ...

Sustainable Biomass Conversions by Highly Efficient Catalytic Processes (SUBICAT)

Date du début: 1 oct. 2013, Date de fin: 30 sept. 2017,

"The goal of a sustainable society requires the efficient use of renewable or sustainable materials and demands the development of selective new methodologies for the preparation of desirable products. In this context we require:(i) a change from traditional stoichiometric, high energy methods that produce huge amounts of chemical waste to mild and clean catalytic processes and(ii) a major step ch ...

European Network on Luminescent Materials (LUMINET)

Date du début: 1 déc. 2012, Date de fin: 30 nov. 2016,

Luminescent materials have entered our every day life. They can be found in lamps, traffic lights, computer screens, cell phones, in labels for goods, are used in medical applications, airport security check devices and many more. Indeed, they have become indispensable and much of societies convenience and welfare depend on them. No wonder that the development and use of luminescent materials has ...

New Anionic Ligands for Base Metal Catalysis (SilaCoFeCC)

Date du début: 1 mars 2013, Date de fin: 28 févr. 2015,

The development of catalysts based on cheap and non-toxic first-row transition metals in replacement of the traditional precious metals is broadly recognized as a key challenge for the development of environmentally friendly chemistry. Here, we propose the development of novel silicon-based ligands specifically tailored to support organometallic chemistry at first-row transition metals (Fe and Co) ...

Nanomaterials for harvesting sub-band-gap photons via upconversion to increase solar cell efficiencies (NanoSpec)

Date du début: 1 juin 2010, Date de fin: 31 mai 2013,

To continue the path of cost reduction in photovoltaics the efficiency of silicon solar cells must be increased. With higher efficiencies more kWh can be produced from the same amount of silicon, which is the dominating cost factor at present. Fundamental loss mechanisms limit the maximum achievable efficiency: around 20% of the incident power is lost, because photons with energies below the band- ...

"PLETHORA transcriptions factors, new players in the control of phyllotaxis in Arabidopsis thaliana" (PLT)

Date du début: 1 mars 2010, Date de fin: 29 févr. 2012,

"The mathematical regularity of plant organ initiation, also known as phyllotaxis, has always intrigued mathematicians and botanists. Only recently was established that the plant hormone auxin has a major role in regulating organ positioning at the shoot apex of plants. Specific spatial accumulation of auxin induces organ formation and control organ spacing. The current model for phyllotaxis relie ...

Role of siRNA-mediated DNA methylation in the root stem cell niche (StemRB)

Date du début: 1 janv. 2010, Date de fin: 31 déc. 2011,

Stem cells are undifferentiated cells that can give rise to different cell types in multicellular organisms. Plant and animal stem cells are usually not specified by the same subset of genes, even though the niche organizations are very similar. The Retinoblastoma (Rb) protein and its plant homologue RETINOBLASTOMA-RELATED (RBR) in stem cell identity however constitutes a possible common pathway i ...
