and its kinetics has been studied under those conditions. When a reaction occurs to a measurable extent over a period of minutes, hours, or days, rate measurements are straightforward. Amounts of reactants or products are measured at various times, and the rates are readily calculated from the...
Variance of the fluctuating turbulent chemical reaction rate is also calculated, verifying that relative variance based on the turbulent equilibrium is low, whereas its classical counterpart (Arrhenius) is pathologically high. A closed set of equations governing reactive turbulent gases is presented on ...
We present a new measurement of the $\\alpha$-spectroscopic factor ($S_\\alpha$) and the asymptotic normalization coefficient (ANC) for the 6.356 MeV 1/2$^+$ subthreshold state of $^{17}$O through the $^{13}$C($^{11}$B, $^{7}$Li)$^{17}$O transfer reaction and we determine...

The rate or speed at which the reactantscombineis high, in part because of the nature of the chemical reaction itself and in part because moreenergy...
We, therefore, characterised the effect of varying the total template concentration and exonuclease concentration on the rate of the autocatalytic reaction (Fig. 4) in buffer solution and when the reaction was localised within the proteinosomes. Fig. 4: Characterisation of autocatalytic PEN DNA ...
Tafel slope is a good indicator of reaction kinetics and the rate-determining step (RDS) of electrocatalytic reactions. In general, different values of the Tafel slope indicate different reaction processes and RDS. As displayed in Fig.3c, the Pt/C enables a Tafel slope value of 62.3 mV...

O¨ zkan and R. T. G¨uray,H. Mach 展开 摘要: The level structure of 18 Ne above the α -decay threshold has been studied using the 16 O( 3 He, n ) reaction. A coincidence measurement of neutrons and charged particles decaying from populated states in 18 Ne has been made. ...
The cage escape quantum yield (ФCE) for both complexes is governed by the relative magnitudes of the cage escape rate (kCE) and in-cage reverse electron transfer (krET; equation (1a,b)). $${\phi }_{{\rm{CE}}}\left({\rm{Ru}}\right)=\frac{{k}_{{\rm{CE}}}\left({\rm{Ru...
rate of colour change could be used to detect the end of the process. Beyond enhanced process control and condition monitoring, we were able to optimize reaction conditions for multicomponent31, heterocycle synthesis32, and catalytic reactions33using feedback from19F NMR, HPLC-DAD, and Raman ...
