The separation ability and retention behaviour of normal phase TLC on silica with eight nonaqueous eluents, has been studied by measuring the retention constants of a series of synthesized benzimidazoles. The separation ability and retention behaviour are discussed in terms of the nature of the solute and eluent....

Copper Oxyl Chloride 3Cu (OH)2∙CuCl2 is dual salt of copper, chlorine, oxygen and water. It is light green salt without smell. In water and organic solutions it is insoluble while it is easily solluble in acids. It is solluble in ammonia thus building complex units. It is more instable product since it is soluted after longer exposure to air a...

The recent I-U measurements on the individual micro needle-shaped crystals, of the ternary mixed valence compound In5Se5Cl, crystallizing in the monoclinic crystal system (P21/m), showed significant light sensitivities. Micro needles of In5Se5Cl “glued” on Si- and Cu- substrates were measured under five different wavelengths with variou...

Efflorescence is a crystalline deposit of water soluble salts on the surface of ceramic masonry. In most cases, efflorescence can be removed by various cleaning methods depending on the chemistry of the crystalline deposit. But this, sometimes, may even worse the problem. Therefore, it would be most desirable to minimize or to prevent the effloresc...

Global Warming Potential – GWP is an agreed quantity which enables determination of an individual green-house gas effect on a global warming process. GWP quantity illustrates how a unit mass of an observed gas contributes to increase of global warming more than an unique mass of CO2, during certain period of time. The paper shows gases and su...
