Copper Ion Activation of Pyrites gotten from Different Localities

Synthesis of Different Copper Oxide Nano-Structures From Direct Thermal Decomposition of Porous Copper(ΙΙ) Metal-Organic Framework Precursors

Copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [Cu3(btc)2] (1) and [Cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°C. It has also been found that the reaction temperature pla...

The probability of tsetse acquiring trypanosome infection from single blood meal in different localities in Kenya.

The probability of tsetse, Glossina pallidipes, acquiring a trypanosome infection from a single blood meal was estimated in five localities on the Kenya coast which were selected for differences in habitat and host availability. The probability that one blood meal contained infective Trypanosoma congolense was 0.0077 in rural areas with domestic animals, 0.0019 in extensive areas of natural hab...

Synthesis and Characterization of Nano-Structure Copper Oxide From Two Different Copper (II) Metal-Organic Framework Precursors

Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...

Preliminary notes on yeasts associated with necrotic cactus stems from different localities in Brazil.

The yeast species found in necrotic stems of three columnar cacti (Pilosocereus machrisii, Pilosocereus vilaboensis, and Praecereus euchlorus) at eight localities in Brazil were described and a similarity analysis using Sorensen distances was used to compare the composition of yeast species at these localities. Of 56 necrotic cactus stems sampled, 32 produced yeast colonies. Ten species of yeas...
