Integrated photovoltaic workstation
The workstation features (i) synthesis, spincoating and annealing area; (ii) thermal evaporator for deposition of conductive metals. Thus far, polymer, all-carbon and perovskite photovoltaics are the major systems we are working on.
Brand: KSV NIMA
MicroBAM enables the visualization of Langmuir monolayers or adsorbate films at the air-water interface for example as a function of packing density.
- Monolayer/film homogeneity. When combined with a KSV NIMA L & LB Trough, observation can be performed during compression/expansion at known surface pressures. Verifying the homogeneity of the monolayer already prior to deposition will speed up the research considerably.
- Optimizing the deposition parameters. For a high quality LB coating, the measurement parameters such as compression speed, waiting times, temperature and subphase content need to be optimized. With MicroBAM it is easy to study the effects of these parameters and choose the optimal conditions.
Langmuir layer structure and behavior studies
- Monolayer/film behavior. It is possible to observe phase changes, phase separation, domain size, shape and packing.
- Monitoring of surface reactions. For example, photochemical reactions, polymerization reactions as well as enzyme kinetics can be followed in real-time.
- Monitoring and detection of surface active materials. For example protein adsorption and nanoparticle flotation.

The underlying principle of NIR-Technology resembles the way a microwave oven works. Microwaves activate the water molecules directly, in contrast to a conventional oven that has to heat up before the energy reaches the target costing or substrate. However, NIR-Technology’s electromagnetic waves have an effect not only on water, as do microwaves, but also, at the highest energy density, molecules of various substances. As a result, NIR-Technology can be implemented in a multitude of industrial processes using near-infrared radiation.
