In Situ and Ex Situ Studies of Platinum Nanocrystals: Growth and Evolution in Solution [PDF]
Journal of the American Chemical Society, 2009 In situ studies on the growth and evolution of platinum nanocrystals in solution were carried out using synchrotron-based X-ray diffraction (XRD) techniques. Ex situ low- and high-resolution transmission electron microscopy (TEM) were used to investigate the nanocrystal morphologies through the different growth stages.

In situ growth optimization in focused electron-beam induced deposition [PDF]
Beilstein Journal of Nanotechnology, 2013 We present the application of an evolutionary genetic algorithm for the in situ optimization of nanostructures that are prepared by focused electron-beam-induced deposition (FEBID). It allows us to tune the properties of the deposits towards the highest conductivity by using the time gradient of the measured in situ rate of change of conductance as the

Cities and Growth: In Situ Versus Migratory Human Capital Growth [PDF]
SSRN Electronic Journal, 2008 University degree holders in large cities are more prevalent and are growing at a more rapid pace than in smaller cities and rural areas. This relatively high rate of growth stems from net migratory flows and/or higher rates of degree attainment in cities. Using data from the 1996 and 2001 Censuses, this paper tests the relative importance of these two
