At long times, a transition occurs to first-order DC kinetics. The reaction rate, t ≈ xt , is determined by the more dilute A side, where a density depletion hole of size xt develops at the interface. For high reactive chain densities on the B side ( R3 > 1 where R is ...
Prepare for the MCAT®by following our organized 3-Month MCAT study plan. Three months is the minimum amount of time most students should study for the MCAT. With just a few months before test day, you’ll need to spend a good amount of time studying each week if you want to score ...
These approaches open up the range of possibilities for teachers. For example, proposing explicit general activities, linked (or not) to a specific issue of science content, to develop students’ understanding of an aspect of the NoS consensus view (Lederman 2007; McComas 2006). Such an ...

These results provide a plausible explanation for the unique impact of m6A on RNA hybridization kinetics atT = 65 °C. m6A does not impact the apparent melting rate because the dominant isomer in the duplex isantiand it melts at a rate comparable to that of the unmethylated RNA. On ...
A systematic investigation on the effect of m7dG on DNA replication has been difficult due to the chemical instability of m7dG. To gain insights into the m7dG effect, we employed a 2'-fluorine-mediated transition-state destabilzation strategy. Specifically, we determined kinetic parameters for ...
We therefore used APT to resolve the near-atomic scale information of the local chemical distribution near the liquid electrolyte/solid interface in three dimensions at the open circuit potential. The as-solutionized specimens were immersed in a deuterated electrolyte (0.1 M KCl in D2O) for 3...
The specific activity of enzymes can be altered over long timescales in cells by synonymous mutations that alter a messenger RNA molecule’s sequence but not the encoded protein’s primary structure. How this happens at the molecular level is unknown. He
Ion-exchange voltammetry as a solid-phase microextraction analytical method: factors influencing the mass transfer to perfluorosulfonated ionomer film-coat... A simple theoretical model of mass transfer kinetics at an electrode coated with an ion-exchange film polymer is proposed. The model takes into...
