The results are reported of an ab initio study of the thermochemistry and of the kinetics of the HOBrO disproportionation reaction 2HOBrO (2) ⇄ HOBr (1) + HBrO(3) (3), reaction ( R4' ), in gas phase (MP2(full)/6-311G*) and aqueous solution (SMD(MP2(full)/6-311G*)). The reaction energy of bromous acid disproportionation is discussed in the context of the coupled reaction system R2-R4 of the FKN ...

The new species Dociostaurus (Kazakia) icconium Sirin & Mol sp. n. (Orthoptera, Acrididae, Gomphocerinae) is described on the basis of morphology and male calling song. The congeneric partner of new species is Dociostaurus (Stauronotulus) cappadocicus (Azam, 1913) whose song description is done for the first time in this study. The species Dociostaurus (Kazakia) brevicollis (Eversmann, 1848) is...

In this study, a detailed chromosome analysis of the endemic Cappadocian Chub, Squalius cappadocicus in Melendiz Stream (Aksaray) was performed. The standard Giemsa staining, C-banding (CBG and CB-DAPI), Ag-NOR technique were applied. diploid number 50; its karyotype formula 14M + 16Sm 10St 10A. Heteromorphic sex chromosomes weren’t detected studied specimens. all chromosomal arms (NF) 90. C-ba...

The acidic bromate oxidation of ferroin in batch reaction proceeds with slow consumption of bromide until a critical bromide concentration is attained. At that point ferroin is suddenly oxidized to ferriin in a process involving autocatalytic generation of bromous acid. Prior to the transition, in an unstirred thin film of solution, a single trigger wave of chemical reactivity may develop and s...

We study the dynamical behavior of one-dimensional arrays of ∼100 μm diameter aqueous droplets containing the oscillatory Belousov-Zhabotinsky (BZ) reaction, separated by narrow gaps of a fluorinated oil. In this closed system, the malonic acid concentration decreases as the reaction proceeds. Starting with a low initial malonic acid concentration, we observe a series of attractors as a functio...
