The average iron/iron-carbide nanoparticle diameter (7.7, 9 and 10 nm) and the width of the size distribution increased with pressure in the sample collection chamber, as a result of the decreasing quenching rate of the plasma jet.
Moreover, previously we found that [23] green luminescence from ZnO nanocrystals with different morphologies is quenched with the decreasing of the surface-to-volume ratio.
When the vacuum chamber with 5/34 of the tunnel volume was connected to the flank of the tunnel, gas explosion of the same concentration would greatly weaken with flame propagation velocity declining to about 200 m/s, the quenching distance decreasing to 3/4 of the tunnel length, maximum peak value overpressure running down to 0.1 0.15 MPa and specific impulse of shock wave below 0.9 kPa s.
The fluorescence intensity or absorbance value of the hydrolysis product of NBD-Cl, namely,4-hydroxy-7-nitrobenzo-2-oxa-1,3-diazole (NBD-OH) is quenched by decreasing the pH of the reaction medium to less than 1.
The absorption value of the hydrolysis product of NBD-Cl, namely, 4-hydroxy-7-nitro-benzo-2-oxa-1,3-diazole (NBD-OH), is quenched by decreasing the pH of the reaction medium to less than 1 by adding 0.2 mL of concentrated HCl.
Such structural change resulted in an obvious ECL intensity increment due to the decreased quenching effect of Fc to the ECL substrate.
After rapid transfer of the complex into deuterated buffer using a spin column, hydrogen deuterium exchange proceeds until it is quenched by decreasing the pH to 2.5 and the temperature to 0 °C.
However, the addition of more Fe and Ta β-stabilizers to Ti 8Fe alloy reduced the likelihood to form α″ martensite during quenching, hence decreasing the volume fraction of α″ phase and finally reaching 3% in Ti 10Fe 10Ta alloy.
Such structural change resulted in an obvious increment in ECL intensity due to the decreased Fc quenching effect to the ECL substrate.
Lowered JSC and VOC together with the decreased PL quenching indicates an increased rate of recombination.
Note that axon usually generates a square response pulse with very short falling time, thus giving rise to a very high quenching rate and decreasing the device conductance due to the amorphization.
