The buoyancy organelles of aquatic microorganisms have to meet stringent specifications: allowing gases to equilibrate freely across the proteinaceous shell, preventing the condensation of water vapor inside the hollow cavity and resisting collapse under hydrostatic pressures that vary with column depth. These properties are provided by the 7- to 8-kDa gas vesicle protein A (GvpA), repeats of w...

The origin of the cold gas in central galaxies groups is still a matter debate. We present Multi-Unit Spectroscopic Explorer (MUSE) observations 18 optically selected local ( z ? 0.017) brightest group (BGGs) to study kinematics and distribution optical emission-line gas. MUSE reveal morphologies including ten complex networks filaments extending up ?10 kpc two compact (< 3 kpc) five extende...

• Hybrid sputtering/gas agglomeration system produces flower-like Zn-Fe NPs. Fast, simple and reliable method to produce bimetallic nanoparticles. Molecular dynamics shows the growth mechanisms of particles. Galvanic couple between Zn –Fe protects Fe from oxidation. Bimetallic nanoparticles have gained attention in last decade due their unusual characteristics compared monometallic counterparts...
