Nail or hammer? We approach electrochemical instrumentation as both a hammer (we built a new hammer, let’s find a nail) and as a nail (we have this nail, but need a better hammer to see what we can do with it). Overall, this approach takes advantage of modern hardware, electronics, and programming. This also entails applying electrochemical tools to solve problems and examining new ways to solve fundamental questions. Ultimately, we are broadly interested in new tools and approaches for measuring electrons and ions. Some of our recent results are below, with more information in the primary research publications.
- Benchtop SEM and SputtercoaterIf asked what we’ll be imaging the most with this instrument, the answer will be nanopipets. Our group has demonstrated a vast range of applications for nanopipets e.g., SICM and SECCM imaging, sensing, electrodeposition, […]
- Potentiometric-Scanning Ion Conductance MicroscopyPotentiometric-Scanning Ion Conductance Microscopy (P-SICM) is a rising sub-class of scanning ion conductance microscopy (SICM) that allows for the simultaneous collection of topography and local apparent conductance. In the Bakergrp, this technique began with […]
- Our New COMSOL Simulation HorsepowerFor electrochemists doing research with scanning probe techniques, COMSOL modeling plays a significant role in instructing experiment design, estimating imaging results affected by pipette geometric, and validating electrochemical phenomena observed. Recently, Baker group has […]
- NSF CCI Center for Single-Entity Nanochemistry and Nanocrystal DesignA consortium from Indiana University, Texas A&M, Temple and the University of Texas have recently been awarded a grant to establish the NSF Center for Chemical Imaging – the Center for Single-Entity Nanochemistry and […]
- Fourth SICM System – DeltaScanning ion conductance microscopy is a versatile tool nanoscale research, including biochemistry, materials, etc. After our first three SICMs: Alpha, Beta and Gamma, we christen our fourth home-made SICM system “Delta” this year. Delta […]
- Single-Entity Nanoparticle SECCMThe Baker group studied single-entity electrochemistry in the collaboration with Ye group (Indiana University Bloomington) to study and characterize electrocatalytic activity of single nanocrystals by utilizing scanning electrochemical cell microscopy (SECCM) and correlative microscopy. […]
- Ion Channel Probe-SICMThe bakergrp developed ion channel probes (ICP) for SICM to expand the functional sensing capabilities of SICM. The initial stage of ICP-SICM was developed in 2014 by Yi Zhou in collaboration with Craig Aspinwall’s […]
