Yinghua Qiu,Preston Hinkle,Crystal Yang,Henriëtte E. Bakker,Matthew Schiel,Hong Wang,Dmitriy Melnikov,Maria E. Gracheva,Maria Eugenia Toimil-Molares,Arnout Imhof,Zuzanna S. Siwy +10 more
TL;DR: This manuscript proposes using pores with longitudinal irregularities as a sensitive tool capable of distinguishing spherical and rod-shaped particles with different lengths between objects of similar volume but different shapes.
Journal ArticleDOI
Highly Charged Particles Cause a Larger Current Blockage in Micropores Compared to Neutral Particles.

TL;DR: It is shown that highly charged hard spheres can cause a significant increase of the resistive-pulse amplitude compared to neutral particles of a similar diameter, and this finding is of crucial importance for sizing particles and characterizing their surface charge properties.
Journal ArticleDOI
Experimental observation of the ion-ion correlation effects on charge inversion and strong adhesion between mica surfaces in aqueous electrolyte solutions.
TL;DR: It is demonstrated that the two mica surfaces may experience the jump-in contact even at high LaCl3 concentrations, which is seldom seen in monovalent salt solutions, which provides important insight into the fundamental understanding in the role of ion-ion correlations in ion screening mechanism and interactions between charged objects.
Journal ArticleDOI
Direction Dependence of Resistive-Pulse Amplitude in Conically Shaped Mesopores
TL;DR: Conditions at which the amplitude of resistive-pulses in a conical mesopore is direction dependent are identified, which are of crucial importance for the resistIVE-pulse technique, which relates the current blockage with the size of the passing object.
Journal ArticleDOI
Visualization of Hydrogen Evolution at Individual Platinum Nanoparticles at a Buried Interface
TL;DR: The rate of hydrogen evolution at PtNP at this buried interface is shown to be a function of Nafion thickness, with the highest activity observed for ~200 nm thick films.
