Crystalline Au dendrites were formed by electrodeposition on a glassy carbon electrode from a solution of HAuCl(4) containing cysteine. The Au dendrites possessed a hierarchical architecture with three-fold symmetry; they comprised trunks, branches, and nanorod leaves, which all grew along the <111> direction.

Here are described the problems and are proposed models and algorithms for the macrosynthesis and for an efficient resource utilization of the computer nodes, of the data trunks, of some network fragments and of the regional computer networks as a whole

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...
