Molecularly imprinted polymers are a class of new functional materials that bring about selectivity to chemical sensors that is similar to that found in biological systems. The technique enables the creation of artificial recognition cavities within synthetic polymers that can be used in chemical...

Diazapolyoxamacrobicyclic compounds form ex-ceptionally stable complexes in organic nonpolar solvents by enclosing certain cations in the tri-dimensional cavity. In the present work, by using hydrogen bonding properties of chloroform.Tetraoxa-1,10-diazabicyclo(8.5«5) eicosane(2.1.1),...

Current densities from 40O Am to 1000 Am were used to investigate the electrowinning of cobalt from sulfate solutiaiie. The cell used was a cylindrical beaker of 1000 ml capacity. Two lead anodes and one stainless steel cathode were used as - electrodes. The cathode was prepared electrolytically...
