Structure and stability of the Si(331)-(12x1) surface reconstruction investigated with first-principles density functional theory

We recently proposed a structural model for the Si!331"-!12!1" surface reconstruction containing silicon pentamers and adatoms as elementary structural building blocks. Using first-principles density functional theory we here investigate the stability of a ...

Disentangling oil weathering at a marine seep using GC×GC: Broad metabolic specificity accompanies subsurface petroleum biodegradation

Jeremy Samuel Arey

Natural seeps contribute nearly half of the oil entering the coastal ocean. However, environmental fate studies generally monitor fewer than 5% of these petroleum compounds. Hence, the rates and relevance of physical, chemical, and biological weathering pr ...

Spongistatins : biological activity and synthetic studies

Pierre Vogel, Sandrine Gerber

During the last two decades, marine organisms such as sponges, tunicates, softcoral and starfish proved to be productive sources of structurally complex metabolites presenting unprecedented architectures.[1] These marine natural products often display unex ...

Drosophila immunity: methods for monitoring the activity of Toll and Imd signaling pathways

Bruno Lemaitre

Invertebrates lack an adaptive immune system and rely on innate immunity to resist pathogens. The response of Drosophila melanogaster to bacterial and fungal infections involves two signaling pathways, Toll and Imd, both of which activate members of the nu ...

Hierarchical assembly of the siliceous skeletal lattice of the hexactinellid sponge Euplectella aspergillum

Georg Fantner

Despite its inherent mechanical fragility, silica is widely used as a skeletal material in a great diversity of organisms ranging from diatoms and radiolaria to sponges and higher plants. In addition to their micro- and nanoscale structural regularity, man ...

Marine isotope stage (MIS) 11 in the vostok ice core: CO2 forcing and stability of East Antarctica

Jérôme Chappellaz

Changes in temperature and carbon dioxide during glacial cycles recorded in Antarctic ice cores are tightly coupled. However, this relationship does not hold for interglacials. While climate cooled towards the end of both the last (Eemian) and present (Hol ...

Biotic interactions of marine algae

UMR 1931, CNRS and Laboratoires Goemar, Station Biologique, 29680 Roscoff, France. Marine algae encompass lineages that diverged about one billion years ago. Recent results suggest that they feature natural immunity traits that are conserved, as well as ot ...

Analysis of steady-state shallow cell solidification in metal matrix composites

Andreas Mortensen

The influence of capillarity on the near-plane front solidification of metal matrix composites is examined by analysis of the one-sided solidification of a binary alloy in a planar interstice of constant width in the limit of low Peclet number. We assume t ...
