In general, the higher the initiator concentration the lower the molecular weight, whereas high monomer concentrations increase molecular weight both when the initiator concentration is limiting and under conditions where a negative cooperative is operating, i.e., whenever the chain transfer reaction
On the other hand, the last phosphodiester transfer reaction
that 1 described was more difficult chemically to do than the phosphodiester transfer reactions
catalyzed by the spliceosome.
In this case, the NMR analysis identified the formation of morpholine end groups arising from the attack of neighboring hydroxyl groups, which possibly correspond to the main chain transfer reaction
. Nevertheless, kinetic analysis showed that the reaction corresponded to a first-order process for the first 2 h: therefore, this evidence would suggest a pseudo-living behavior in initial polymerization steps.
Cardiff City live transfer reaction
: Neil Warnock holds press conference after deadline day
Xia, "Structure orientation of hemin self-assembly layer determining the direct electron transfer reaction
," Chemical Communications, vol.
Electron transfer reaction
was initiated by adding 0.5-40 [micro]M PfFd and 100 [micro]M NADPH, and the absorbance was monitored for 5 min with 10-second intervals at 550 nm.
Thekedar, Investigations on the Use of Breath Gas Analysis with Proton Transfer Reaction
Mass Spectrometry (PTR-MS) for a Non-Invasive Method of Early Lung Cancer Detection, Acta Geodaetica Et Cartographic Sinica, 2009.
The coupling of chemical reaction to the electron transfer reaction
can easily be detected with the help of the shifting of peak potentials as well as by the change in the ratio of peak currents.
At day 3, the [R.sub.ow] and [R.sub.b] magnitudes indicate the number of potential sites available for the charge transfer reaction
. The resistance of the pore wall, [R.sub.ow], was determined to be 6091 [OMEGA] [cm.sup.2], while the resistance of the pore base, [R.sub.b], was estimated to be 606 [OMEGA] [cm.sup.2], which is less than the wall resistance, [R.sub.ow].
The scientists have developed a mechanical model mouth interfaced with proton transfer reaction
mass spectrometry, which they are using for the rapid analysis of the release of VOCs under swallowing conditions.
Rollers within the instrument sequentially transfer reaction
steps from one "blister" to the next, with results being available in about an hour.
