PHOTO CHROMATIC SENSORS OF MULTINARY MIXED VALENCE INORGANIC MICRO NEEDLES
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...

SEPARATION AND RETENTION BEHAVIOUR OF BENZIMIDAZOLE DERIVATIVES IN THIN LAYER CHROMATOGRAPHY ON SILICA GEL
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....

WASTE COPPER USAGE FOR PLANT FUNGICIDE PRODUCTION
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...

MEMBRANE PROCEDURES IN COMMUNAL WASTE LANDFILL LEACHATE TREATMENT
One of basic problems faced in practice of landfill waste treatment is a problem with landfill leachate. The intensity of their production, thus their quantity, depends on numerous factors: landfill age, waste types, microclimatic parameters and similar. This leachate must not be discharge directly into the environment without their previous collec...

EFFECT AIRCRAFT EXHAUST GASES ON SUM OF GREEN-HOUSE ATMOSPHERE GASES
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...
