The laser pyrolysis reactor consists of a CO2 laser that strikes the reagents in the gas phase, allowing their rapid atomic decomposition and the synthesis of nanoscale materials. It requires very short reaction times, there are practically no secondary products that impurify the nanomaterials and it allows continuous production. Carbon-based catalysts with isolated metal atoms, low-toxicity luminescent materials (carbon dots) and iron oxide nanoparticles have been synthesized.
Our laser pyrolysis unit uses a laser beam to selectively heat a gas stream containing one or more decomposing precursor chemicals, inducing the nucleation of nanoparticles. The short and well-controlled residence time in the reaction zone is particularly suitable for the production of very fine homogeneous nanoparticles. In addition, we have developed liquid collection systems that minimize agglomeration and we are able to use not only gases but also liquid and solid phase precursors, thanks to a mist chamber that allows the feeding of micron-sized aerosols.

It is a technique that allows to manufacture homogeneous polymeric fibers and particles or of core-corona structure, aligned, porous, etc. It allows working with natural or synthetic polymers or a combination of them. During the formation of the fibers or particles, inorganic or organic materials (nanoparticles, oils, drugs, etc.) can be encapsulated, opening up the possibility of a multitude of applications (membranes, dressings, catalytic supports, scaffolds for tissue engineering, etc.).

Continuous flow reactors based on microfluidic principles offer potential solutions to the above concerns. The exquisite control offered by microfluidic reactors enables the continuous production of nanocrystals with well-defined sizes, shapes and composition. We have designed versatile microfluidic synthesis platforms to produce a large library of nanostructures continuously, often with a sharp reduction in processing times relative to the corresponding batch process. We have demonstrated that even complex multi-step processes can be translated into continuous microfluidic production. Furthermore, we use segmented flow reactors not only to homogenize residence time distributions, but also to achieve unprecedented flexibility in terms of adjusting the reaction atmosphere.

The institute has a series of tubular furnaces for the synthesis of ceramics, as well as programmable muffles with precise heating control, programmable up to about 1000 degrees Celsius.
Titanium heating plate is also available which allows processing of electrodes with precise heating control up to approximately 680 degrees Celsius.
1) Arc furnace for the growth of massive samples (several grams) of intermetallic compounds. The furnace is manually operated, very simple. A muffle is also available next to the arc furnace in which post-synthesis heat treatments can be performed at ambient atmosphere.
