MAY THE HONEY BEES SENSITIVITY TO EARTH’S MAGNETIC FIELD ASSIST THEM FOR BUILDING?
Autor: Alexander POKUTSA, Jacques MUZART
Publikováno v: Uludağ Arıcılık Dergisi. 22:1-4
A surprising D12 symmetry inside-hive constructions of honey bees were disclosed. The well-established sensitivity of bees to the magnetic field led us to supposition that it may play a key role in steering of such regular architecture.

'Blind' physics vs engineering prowess: can each theory taken independently explicate the awesome design of bees comb?
Autor: Alexander POKUTSA, Andriy ZABOROVSKYİ
Publikováno v: Uludağ Arıcılık Dergisi.
The manner of the bees construct their honeycombs and it design may imply, besides the partaking of physical laws, also the coordinated activity many dozens of colony individuals all through the way of cells foundation to full size erection. The last

Cyclohexane oxidation: relationships of the process efficiency with electrical conductance, electronic and cyclic voltammetry spectra of the reaction mixture
Autor: Pawel Bloniarz, Andriy Zaborovsky, Jacques Muzart, Tomasz Paczeŝniak, Alexander Pokutsa, Dariya Maksym
Publikováno v: Reaction Kinetics, Mechanisms and Catalysis. 132:123-137
The cyclohexane oxidation by H2O2 using VO(acac)2 as starting catalyst in the presence of oxalic acid (OA) was studied. The dissociation of OA and VO(oxalate) formed in situ by interaction of VO(acac)2 with OA is the essence of the electrical conduct

Sustainable oxidation of cyclohexane catalyzed by a VO(acac)2-oxalic acid tandem: the electrochemical motive of the process efficiency
Autor: Alexander Pokutsa, Orest Fliunt, Pawel Bloniarz, Tomasz Paczeŝniak, Andriy Zaborovskyi, Yuliya Y. Kubaj
Publikováno v: RSC Advances. 10:10959-10971
Cyclohexane oxidation by H2O2 to cyclohexanol, cyclohexanone, and cyclohexylhydroperoxide under mild (40 °C, 1 atm) conditions is significantly enhanced in the system composed of VO(acac)2 (starting catalyst) and small additives of oxalic acid (proc
