We report the experimental effects of temperature on spontaneously nucleated trigger waves in a quasi-two-dimensional BZ reaction-diffusion system, conducted isothermally at temperatures between 9.9 and 43.3 °C. Novel application of filter-coupled circle finding and localized pattern analysis is shown to allow the highly accurate extraction of average radial wave velocity and nucleation period. Using this, it is possible to verify a strong Arrhenius dependence of average wave velocity with temperature, which is used to find the effective activation energy of the reaction in accordance with predictions elaborated from the widely used Oregonator model of the BZ reaction. On the basis of our experimental results and existing theoretical models, the value for activation energy of the important self-catalyzed step in the Oregonator model is determined to be 86.58 ± 4.86 kJ mol-1, within range of previous theoretical prediction.The number of approved peptide therapeutics, as well as those in development, has been increasing in recent years. Frequently, the biological activity of such peptides is elicited through the adoption of secondary structural elements upon interaction with their cellular target. However, many therapeutic peptides are unstructured in solution and accordingly exhibit a poor bioavailability due to rapid proteolysis in vivo. To combat this degradation, numerous naturally occurring peptides with therapeutic properties contain stabilizing features, such as N-to-C cyclization or disulfide bonds. Recently, hydrocarbon stapling via non-native amino acid substitution followed by ring-closing metathesis has been shown to induce a dramatic stabilization of α-helical peptides.
