Efficient photosynthesis of carbon monoxide from CO2 using perovskite photovoltaics
Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Jingshan Luo, Antonio Abate, Matthew Thomas Mayer, Marcel Roland Schreier, Ludmilla Steier
Artificial photosynthesis, mimicking nature in its efforts to store solar energy, has received considerable attention from the research community. Most of these attempts target the production of H-2 as a fuel and our group recently demonstrated solar-to-hy ...
Nature Publishing Group2015Interactions of silver and polystyrene nanoparticles with algae
Nanoparticles have various physicochemical properties attributed by their small dimensions. The global production of nanoparticles lead to a raised concern for their environmental impacts. Algae are of highly ecological importance functioning as primary pr ...
EPFL2015Ecological response of trees to simulated climate change along an altitudinal gradient (CLIMARBRE)
Alexandre Buttler, Constant Signarbieux, María Paula Sanginés De Cárcer
Assessing the impacts of climate change on mountain ecosystems is challenging as it takes several decades to observe an ecological response. Using a transplantation experiment in the Swiss Jura Mountains we study the adaptability of beech and spruce to sim ...
2014The ultrastructure of Chlorobaculum tepidum revealed by cryo-electron tomography
Chlorobaculum (Cba) tepidum is a green sulfur bacterium that oxidizes sulfide, elemental sulfur, and thiosulfate for photosynthetic growth. As other anoxygenic green photosynthetic bacteria, Cba tepidum synthesizes bacteriochlorophylls for the assembly of ...
Elsevier BV2014Scales and drivers of temporal
Tom Ian Battin, Hannes Markus Peter
The role of inland waters for the global carbon cycle is now recognized and evidence increasingly suggests that stream ecosystems disproportionately contribute to the carbon cycle. Understanding the dynamics and drivers of stream water partial pressure of ...
2014Carbon nanotubes quench singlet oxygen generated by photosynthetic reaction centers
László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi, Krisztina Nagy
Photosensitizers may convert molecular oxygen into reactive oxygen species (ROS) including, e.g., singlet oxygen (O-1(2)), superoxide anion (O-2(-center dot)), and hydroxyl radicals ((OH)-O-center dot), chemicals with extremely high cyto- and potential gen ...
Wiley-V C H Verlag Gmbh2013Data-Link pour un système de transfert d'énergie par induction
Par définition, un système de transfert d’énergie par induction (ou sans contacts) se passe de connexion matérielle entre la source d’énergie et le consommateur. Néanmoins et selon les cas, un transfert d’informations entre les deux parties peut être requi ...
2012Métaphores machinales
Au fil des siècles, l'homme se voit comme une machine successivement hydropneumatique, mécanique, électrique et aujourd'hui numérique. Chaque nouvelle invention offre une nouvelle perspective sur le vivant sans jamais toutefois être complètement satisfaisa ...
Vrin2011Clinique psychiatrique Sihlfeld
Les hôpitaux de jour ont fortement gagné en importance ces dernières années, suivant la hausse des traitements ambulants ou semi-stationnaires des personnes souffrant de psychose. Cependant, ces institutions sont logées, dans la plupart des cas, dans des m ...
2011Dynamic and reversible self-assembly of photoelectrochemical complexes based on lipid bilayer disks, photosynthetic reaction centers, and single-walled carbon nanotubes
An aq. soln. contg. photosynthetic reaction centers (RCs), membrane scaffold proteins (MSPs), phospholipids, and single-walled carbon nanotubes (SWCNTs) solubilized with the surfactant sodium cholate (SC) reversibly self-assembles into a highly ordered str ...
