Timing matters: the underappreciated role of temperature ramp rate for shape control and reproducibility of quantum dot synthesis.

Understanding the coupled kinetic and thermodynamics factors governing colloidal nanocrystals nucleation and growth are critical factors in the predictable and reproducible synthesis of advanced nanomaterials. We show that the temporal temperature profile is decisive in tuning the particle shape from pseudo-spherical to monodisperse cubes. The shape of the nanocrystals was characterized by tran...

Igr J17098-3628: an X-ray Nova Discovered by Integral

We report the discovery with INTEGRAL on March 24, 2005, and follow-up observations of the distant Galactic X-ray nova IGR J17098-3628.

NGC 3628: Ejection Activity Associated with Quasars

NGC 3628 is a well-studied starburst/low level AGN galaxy in the Leo Triplet noted for its extensive outgassed plumes of neutral hydrogen. QSOs are shown to be concentrated around NGC 3628 and aligned with the HI plumes. The closest high redshift quasar has z=2.15 and is at the tip of an X–ray filament emerging along the minor axis HI plume. Location at this point has an accidental probability ...

The star - burst galaxies NGC 278 , NGC 660 , NGC 3628 , NGC 4631 , and NGC 4666

Aims. We study the physical properties and mass of molecular gas in the central regions of galaxies with active nuclei. GHz [CI] maps in three of these are used to model the molecular gas. Results. All five objects contain bright CO emission in the central regions. Clear central concentrations were found in NGC 660, NGC 3628, and NGC 4666, but not in the weakest CO emitters NGC 278 and NGC 4631...
