Determination of Zeta Potential via Nanoparticle Translocation Velocities through a Tunable Nanopore: Using DNA-modified Particles as an Example Emma L. C. J. Blundell1, Robert Vogel2,3, Mark Platt1 1Department of Chemistry, School of Science, Loughborough University, 2Izon Science Limited, 3School of Mathematics and Physics, The University of Queensland Here we use a polyurethane tunable nanopore integrated into a resistive pulse sensing technique to characterize nanoparticles surface chemistry via the measurement of particle translocation velocities, which can be used to determine the zeta potential of individual nanoparticles.
A Simple, Low-cost, and Robust System to Measure the Volume of Hydrogen Evolved by Chemical Reactions with Aqueous Solutions Paul Brack1, Sandie Dann1, K. G. Upul Wijayantha1, Paul Adcock2, Simon Foster2 1Department of Chemistry, Loughborough University, 2Intelligent Energy Ltd The study of methods to generate on-demand hydrogen for fuel cells continues to grow in importance. However, systems to measure hydrogen evolution from the reaction of chemicals with water can be complicated and expensive. This article details a simple, low-cost, and robust method to measure the evolution of hydrogen gas.
Adapting the Electrospinning Process to Provide Three Unique Environments for a Tri-layered In Vitro Model of the Airway Wall Jack C. Bridge1, Jonathan W. Aylott2, Christopher E. Brightling5, Amir M.
