WebJan 9, 2024 · It was observed that the rate determining step of the process is the opening of the L-lactide ring and that by increasing the steric hindrance, evaluated by changing geometric parameters and topographic steric maps, or the electron-withdrawing properties of the ligand, the corresponding energy barrier increases. WebAt the end of the page you find the steric map of the ligand and the corresponding color bar. Positive values of the isocontour lines refer to the down half-sphere, which is the half …

WebOct 7, 2024 · Topographic steric maps provided a 3D image of catalytic pocket, namely, the region of the catalyst where the substrate bound and reacted. The percentage of buried volume (% V Bur) was introduced to quantify the fraction of the coordination sphere around a metal center that was occupied by the organic ligand. WebThe maps shown through topoView are from the USGS’s US Topo series and earlier Historical Topographic Map Collection (HTMC). The term “US Topo” refers specifically to quadrangle topographic maps published in 2009 and later. These maps are modeled on the familiar 7.5-minute quadrangle maps of the period 1947-1992, but are mass-produced ... WebMay 26, 2024 · The steric environment of a catalytically active site experienced by the substrates is key to determine favorable reaction pathways. Square planar coordinated active sites, as encountered in innumerable d 8-metal catalysts, are particularly challenging in this regard due to the relatively low coordination number and the consequently large … qt graphics view mousemove
