MATERIAL SYNTHESIS

Chemical laboratory equipped for the synthesis of colloidal nanomaterials. It has the necessary apparatus for the synthesis of metallic inorganic nanoparticles, metallic oxides, semiconductors and perovskites. Composed of an inert gas/vacuum line (Schlenk) and precise temperature control, the system allows obtaining nanoparticles with high morphological control. The dry chamber (glovebox) together with the Schlenk line make it possible to carry out experiments in a controlled environment in the absence of moisture in a nitrogen atmosphere. Thus, the LNNano nanomaterials synthesis laboratory is equipped to obtain nanomaterials that require high reaction control.

Equipment

The laboratory is equipped with all the necessary infrastructure for the synthesis and purification of nanomaterials in a controlled environment. Equipped with a dry camera (glovebox) with humidity and oxygen control, enabling the stocking and handling of reagents in an inert environment. The reaction flasks (3-mouth flasks) can be manipulated in a controlled environment and, later, coupled to the Schlenk line, which has control of the vacuum level and nitrogen flow. Comprised of a heating blanket system (up to 400 °C) and high-precision Eurotherm temperature controllers (PID system), the control of the nucleation and growth steps of the nanoparticles can be achieved precisely through both heating rates. and by the stable control of temperature levels.

The laboratory has a set of centrifuges, including one in a controlled environment, allowing the purification steps to be carried out, avoiding oxidation and optimizing the surface characteristics of the nanomaterials. The experimental apparatuses were designed for the synthesis of several nanomaterials with high control of size, shape and surface characteristics, including metallic inorganic nanoparticles, metallic oxides, semiconductors and perovskites.

2D nanomaterials

Obtaining 2D nanomaterials is also possible in the synthesis laboratory through both chemical and mechanical routes. Equipped with ultrasound and thermostatic baths, the exfoliation of materials to obtain 2D systems using acoustic cavitation with temperature control can also be performed. The LNNano synthesis laboratory is equipped for the synthesis of several inorganic nanomaterials including systems that require high reaction control.
