The bark of several coniferous species, a waste product of the timber industry, contains significant amounts of natural antioxidants. In our ongoing studies of Nepalese medicinal plants, we examined the bark from Abies spectabilis as the starting mat

This review is a deep study of the Bray’s 1921 paper that reported the observation of the first periodic reaction in homogeneous phase. The paper obtained a general indifference by other chemists and some opposition due to the fact that it seemed t

Oscillating chemical reactions in the homogeneous phase have been studied intensively only since the mid-1960s, but they were known since 1920, having as forerunners the chemist William C. Bray and an “atypical” chemist Alfred J. Lotka. This cont

Coenzyme Q10 (CoQ10) is the prevalent ubiquinone in human organism, largely present in its reduced form, ubiquinol (QH2), to which the antioxidant, free radical scavenger activity is ascribed by many authors. However, some studies indicate that also

The interesting behavior of the Briggs–Raucher oscillating reaction does not stop with the end of oscillations. Depending on the initial concentrations, the classic mixture with malonic acid may undergo a sudden transition from a state with low [I2

The system KSCN-H2O2-CuSO4-NaOH, also known as the OrbA n-Epstein oscillatory reaction, is exposed to external perturbations by several phenolic compounds: catechol, resorcinol, hydroquinone, 2,5-dihydroxybenzoic acid, 2,6-dihydroxybenzoic acid, 2,3-

The KSCN-H2O2-NaOH-Cu(II)-catalyzed system is one of the few reactions in which chemical oscillations can be observed in batch conditions. In the present paper, this oscillating reaction was revisited in a wide range of initial concentrations of all

The reaction of 4-acetoxy-azetidinone and (3R,4R)-4-acetoxy-3- [(1R)-1-(tert-butyldimethylsilyloxy) ethyl] azetidin-2-one with unprotected polyphenols in aqueous solution was studied. Different ratios of mono-azetidinone and bis-azetidinone adducts w

The intermittency or intermittent bursting as the type of dynamic state when two qualitatively different behaviors replace one another randomly during the course of the reaction, although all the control parameters remain constant, is found in the Br
