We develop and test different tools for research, especially for scanning electrochemcial microscopy (SECM), a method that we intensively use and for which we develop new procedures and applications.
Below is a list of our key publikations, in which important hardware developments are documented for scanning electrochemical microscopy (SECM).
SECMx is a controll programm for SECM instruments. It can operate with different hardware systems and allows to flexibly adapt setups to specific tasks while keeping the same software. The software can be easily expanded by adding new instrument drivers or programming new experiments.
The demo version allows you to see the experiments and the organisation. It can also "perform" experiments by simulating the behaviour of connected virtual devices. For a full version contact Gunther Wittstock

The software works with the following hardware:
PhysikInstrumente, Märzhäuser, Mechonics, SPI, SmarAct and Owis
Ivium, Ivium with WE32 multiplexer, Ivium plus, npi with various current and voltage ranges, CHI, Gamry as monopotentiostat and bipotentiostat, PalmSense, Jaissle, generic analog devices, home-built analog potentiostat
Plug In DAS PCI 1602/16, Plug In CIO DAS 1602_16, Plug In DAS6036, USB2627
Plug In DDA4 and DDA8, Plug In CIO DAC 02_16
NI FPGA card, limited functions
Regulated light source:
Zahner, NKT super continuum source
New drivers are added as the need appears.
MIRA stands for „microscopy image rapid analysis”. It is a software evaluation and documentation of SECM measurements and also handles other electrochemical data from various instrument manufacturere and home-built instruments according to a uniform standard.
It contains productivity tools that were developed for everyday laboratory routines.
Demo version, 64 bit system, 126 MB
Demo version, 32 bit system, 126 MB
Software requirements: Windows 7, Windows 10, running in 24 bit color depth or 256 bit color depth. It has full functionallity but can only load the example data files that are supplied with the demo distribution. For a full version contact Gunther Wittstock.

The open access publication listed below documents the developemnt of a very affordable, flexibly programmable dipping robit for repetitive imersion/emersion protocols, for instance for layer-by-layer deposition of functional materials. The instrument is maded by reconfiguring and reprogramming a 3D printer. It makes use of 3D-printed hardware components and Ardunino control electronics. All programs and construction documentation are available for download in the Supporting Information of the publication.
