Kinetics of Hole Nucleation in Biomembrane Rupture.
The core component of a biological membrane is a fluid-lipid bilayer held together by interfacial-hydrophobic and van der Waals interactions, which are balanced for the most part by acyl chain entropy confinement. If biomembranes are subjected to persistent tensions, an unstable (nanoscale) hole will emerge at some time to cause rupture. Because of the large energy required to create a hole, th...
متن کاملFaster nucleation at lower pH: amorphous phase mediated nucleation kinetics.
Faster nucleation of hydroxyapatite (HAP) at lower pH (with lower supersaturation) contradicts classical understanding. We find that the residue calcium ion in the mother liquor is the key to trigger ACP phase transformation, which gives an understanding of nonclassical nucleation kinetics of ACP-mediated crystallization and sheds light on biomineralization.
متن کاملKinetics of two-step nucleation of crystals.
When the nucleation of a stable crystalline phase directly in a supersaturated old phase is greatly retarded, the crystal nuclei might nucleate within faster-forming particles of an intermediate phase. Here we present a theoretical investigation of the kinetics of this two-step nucleation of crystals and derive general expressions for the time dependence of the number of crystals nucleated with...
متن کاملThe kinetics of actin nucleation and polymerization.
The polymerization kinetics of rabbit skeletal muscle actin was studied by following the increase in fluorescence of tracer amounts of actin conjugated to N-pyrenyl iodoacetamide. The observed polymerization kinetics could be precisely fit by numerical integration of equations describing a nucleation-elongation process. Under all conditions tested, the rate of nucleation was proportional to the...
متن کاملMicrofluidic droplet method for nucleation kinetics measurements.
In this work, we developed a microfluidic equivalent of the classical droplet method for investigating nucleation kinetics. Our microfluidic device allows us to store hundreds of droplets of small volume ( approximately 100 nL) and to accurately control their temperature. We also monitor directly all the stored droplets, and thus perform statistical measurements on a large number of nucleation ...
