Abstract: A method of making a colloidal solution of high confinement semiconductor nanocrystals includes: forming a first solution by combining a solvent, growth ligands, and at most one semiconductor precursor; heating the first solution to the nucleation temperature; and adding to the first solution, a second solution having a solvent, growth ligands, and at least one additional and different precursor than that in the first solution to form a crude solution of nanocrystals having a compact homogenous semiconductor region. The method further includes: waiting 0.5 to 20 seconds and adding to the crude solution a third solution having a solvent, growth ligands, and at least one additional and different precursor than those in the first and second solutions; and lowering the growth temperature to enable the formation of a gradient alloy region around the compact homogenous semiconductor region, resulting in the formation of a colloidal solution of high confinement semiconductor nanocrystals.

Abstract: A fence stretcher bar manufactured from a continuously fed, hot dip galvanized bar and a method of making such a stretcher bar. In a first manufacturing phase, the bar is formed from a continuously fed round rod which is rolled into a flat bar and coiled on a mandrel. The flat bar is then continuously fed into a second phase of the operation which includes annealing, cleaning with acid, coating with zinc ammonium chloride and hot dip zinc galvanizing. The material is cut to length and the cut ends are flame-spray coated with zinc. The bar is of substantially longitudinal configuration with two cut ends substantially perpendicular to a longitudinal axis thereof and having a cross section defining two parallel planar sides and two transverse curvilinear convex surfaces.
