2D transfer station

A 2D materials microscopic transfer system is a specialized setup for moving atomically thin materials between substrates. It typically consists of an optical microscope, XY stage, heater, and micromanipulator. The system aligns 2D flakes on a polymer with a target substrate using the XY stage for precise positioning. A heater controls adhesion and release through temperature manipulation. Operators locate desired flakes under the microscope, position them over the target, apply heat, and transfer the flake with micrometer-level precision. This process enables the assembly of complex 2D material heterostructures, crucial for nanotechnology research and development.

High energy ball mill

The ball mill (Pulverisette 7 classic line, Fritsch) enables to crush diamonds into powders with a final fineness below 1 μm as a result of collision with grinding balls. Wet grinding in a suitably reactive solvent might allow for a simultaneous disaggregation and functionalization of the diamond particles.

Seeding station

Spin coater and ultrasonic baths for coating and seeding.

Ultrasonic homogenizers

The ultrasonic homogenizer (Sonopuls HD 4200, Bandelin) is used for disaggregation of the diamond particles with high-performance, 20kHz ultrasound. Depending on the choice of the solvent and additional, chemically active compounds, the process of decreasing the size of the diamond particles may be paired with their functionalization.

The refrigerated – heating circulator (CORIO CP-200F, Julabo) is used to control the temperature throughout disaggregation of the diamond particles. Avoids the effect of overheating and excessive evaporation of the solvent.particles may be paired with their functionalization.

Plasma cleaners

Plasma cleaner 13.56 MHz

The plasma cleaner (ZEPTO, diener) enables cleaning and termination of diamond surfaces. The 2.6 liter chamber allows for oxygen modification of the diamond surface. The generated plasma RF (13.56 MHz) changes the hydrophobicity of the diamonds and sterilizes them.

Plasma cleaner 40 kHz

The plasma cleaner (ZEPTO, diener) enables cleaning and termination of diamond surfaces. The 2.6 liter chamber allows for oxygen modification of the diamond surface. The generated plasma RF (40 kHz) changes the hydrophobicity of the diamonds and sterilizes them.

Nanoparticles analysis

The particle analyser (Zetasizer Nano ZS, Malvern Panalytical) utilizes optical measurement techniques based on light scattering to measure a size distribution (in a range of 0.3 nm to 10 µm), and a zeta potential (in a range of -500 mV to 500 mV) of the diamond particles suspended in liquids. Both quantities are crucial in production, disaggregation, and functionalization of the nanodiamonds. The measurement of the size distribution enables to quickly control parameters and verify results of the ball milling and/or the ultrasonic treatment, while the value of the zeta potential indicates the colloidal stability of the particles in a specific dispersion medium, and provides better understanding of the processes of charge transfer occurring due to the modification of the nanodiamonds’ surface.
