Mn(IV) acetate was generated in acetic acid solutions and characterized by UV-vis spectroscopy, magnetic susceptibility, and chemical reactivity. All of the data are consistent with a mononuclear manganese(IV) species. Oxidation of several substrates was studied in glacial acetic acid (HOAc) and in 95:5 HOAc-H(2)O. The reaction with excess Mn(OAc)(2) produces Mn(OAc)(3) quantitatively with mixe...

Recent evidence suggests that the reaction between nitrite and deoxygenated hemoglobin provides a mechanism by which nitric oxide is synthesized in vivo. This reaction has been previously defined to follow second order kinetics, although variable product stoichiometry has been reported. In this study we have re-examined this reaction and found that under fully deoxygenated conditions the produc...

In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...

This paper introduces the other papers in this issue, describing and arguing for the context in which they were written – a conference that was, unusually, based in conversation rather than reporting through the presentation of papers: and a refereeing process that continued after the initial presentation (at the conference) of the work reported, thus allowing responses to critical comments. Ma...

Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide (LDH) in a batch reactor was investigated this study. The kinetic experiments indicated that the sorption from synthetic feed solution synthesised LDH very fast, with over 98% removal being achieved within 5 min contact. Kinetic modeling process to different models (pseudo first order, pseudo second Elovich and intraparticle dif...

summing the Boltzmann factor over all spin configurations {si}. The enumeration of all configurations cannot be done for d ≥ 3, and although possible in d = 2 is extremely hard there as well (a problem solved by Onsager). We will use an approximate solution technique known as mean field theory. Last term we solved the problem of noninteracting spins in a magnetic field described by the Hamilton...
