Replication of nanostructures on polymers using controlled pressure and temperature. The sructres can be cured by heat (Thermal NIL) or UV light (step-and-flash lithography – SFIL) during the imprinting process.
This technique is widely used for microstructure fabrication for electrical, optical, photonic and biological applications.

Volume and density measurement of porous solids and powders.
Fully automated gas pycnometer, for the measurement of volume and density of powders, granular materials, and solid objects. Typical applications include: porous materials such as catalysts and activated carbons, pharmaceuticals and excipients , foods (raw, refined and end products), ceramics and refractory materials, geological samples (soils, rocks, sediments), building materials (concrete, cement), polymers and composites.
The equipment for this purpose is Ultrapyc 1200e Helium Pycnometer (Quantachrome Instruments).
Customer benefits
The equipment provides density measurements of solids and powders for customers who need to characterise this property and add value to their materials.
Target customer
Universities, public research organisations and pharmacological and chemical industries.
Additional information
Each particle of a solid material has effectively the same true density regardless of size or shape, but more or less geometric space is occupied by the material according to the relative particle-particle cohesion and mechanical interference. That is, the apparent bulk densities of powdered, granular or flaked materials are highly dependent on the manner in which the particles are packed together. Furthermore, handling or vibration of particulate material causes the smaller particles to work their way into the spaces between the larger particles. The geometric space occupied by the powder decreases and its density increases; ultimately no further natural particle packing takes place without the addition of pressure and maximum particle packing is achieved.
The equipment for this purpose is Autotap (Quantachrome Instruments).
Customer benefits
The equipment provides tapped density measurements of powders for customers who need to characterise this property and add value to their materials.
Target customer
Universities, public research organisations and industries.

Freeze drying (also known as lyophilization) is a water (or other solvents) removal process typically used to preserve materials, with the goal of extending their shelf life or reducing its weight. Freeze drying works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimation).
Freeze drying occurs in three phases:
