A possible connection between phosphate tungsten bronzes properties and Briggs-Rauscher oscillatory reaction response
نویسندگان
چکیده
The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). influence of solid insoluble materials Ca- PWB, as well lithium doped (Li-PWB) cation free (PWB) bronzes on the oscillatory Briggs-Rauscher (BR) reaction dynamics, is compared. results show that doping with Li Ca reduces sensitivity BR towards addition. These findings suggest usage an innovative method for testing different properties material. behavior PWB in significantly changed divalent (Ca2+) doping. reasons were found their calculated unit cell volumes. Namely, compressed Ca-PWB volume indicates difficult availability active site heterogeneous catalysis. Hence, linear correlation (slope) oscillogram?s length (?osc) vs. mass might be considered a new parameter evaluation catalytic activity.

Application of Briggs-rauscher Reaction for Measurement of Antioxidant Capacity of Croatian Wines
Briggs-Rauscher (BR) reaction is one of the most commonly studied oscillation reactions which has been applied for measurement of antioxidant activity of water-soluble substances. By addition of free radicals (from fruits or vegetables), there is an immediate quenching of oscillations. The reaction is followed potentiometrically and the inhibition time (IT), or time of no oscillations, is propo...
متن کاملThe Bray-liebhafsky and Briggs-rauscher Oscillating Reactions
The common points and differences between the Bray-Liebhafsky and BriggsRauscher reactions are discussed. The reactants of the non-catalyzed version of the Briggs-Rauscher reaction being the same as those of the Bray-Liebhafsky reaction plus a reducing organic compound, the mechanisms of these two systems must have several common points. The marked difference between the oscillating behaviours ...
متن کاملA Galois-Connection between Myers-Briggs' Type Indicators and Szondi's Personality Profiles
We propose a computable Galois-connection between Myers-Briggs’ Type Indicators (MBTIs), the most widely-used personality measure for non-psychiatric populations (based on C.G. Jung’s personality types), and Szondi’s personality profiles (SPPs), a less well-known but, as we show, finer personality measure for psychiatric as well as non-psychiatric populations (conceived as a unification of the ...

association between [chronic PM] air pollution exposure and health [mortality]." In applying these criteria, I have included experimental studies in animals and epi-demiologic studies in humans (6). Rodents exposed to high concentrations of diesel exhaust for life did not show early or increased mortality (6). The available epi-demiologic studies (3-5) showed only weak associations across a nar...
متن کاملA Connection between Decomposability of Ultrafilters and Possible Cofinalities
We introduce the decomposability spectrum KD = {λ ≥ ω|D is λ-decomposable} of an ultrafilter D, and show that Shelah’s pcf theory influences the possible values KD can take. For example, we show that if a is a set of regular cardinals, μ ∈ pcf a, the ultrafilter D is |a|-complete and KD ⊆ a, then μ ∈ KD. As a consequence, we show that if λ is singular and for some λ < λ KD contains all regular ...
