Today it's Pallavi Dutta's turn to don the thesis submission hat! Pallavi has made an awesome contribution to our understanding of nanopipette ion transport, and how to utilise ion rectifying pipettes for sensing DNA and pesticides at super-low analyte concentrations.

Today we say goodbye to @EmerFarell (pictured with the thesis submission 👑). The first submission from my group at UCD. Emer has worked so hard over the past three years and made a massive contribution to our understanding of ICR in aprotic solvent. We will all miss you Emer!

Very pleased to see this work, led by @DulebaDominik out in it's final version. We hope that the new model, which takes into account accumulation/depletion of H+/OH- in addition to bulk electrolyte, will be useful for the nanopore and SICM communities.

Happy to see this nice piece led by @SONeill1998 and @adri_7792, in collaboration with @GGil_Ramirez in print. We demonstrate an effective method to modify BDD electrodes using a custom synthesized diazonium and compare the layer properties to that on GC. @ucdchemistry.
