Division Structure Analysis is currently seeking a student (w/m/d) for a bachelor or master thesis "Design and synthesis of multivariate nano sized metal organic frameworks for electrochemical application”
Recently, Nanoscale MOFs have drawn tremendous attention for their variety of unique properties which are not observed in their relatively higher sized crystallites. Nanocrystals of MOFs have several advantages towards processibility owing to their better homogeneous in-solvent dispersion for device fabrication. Recent research reports in the field of nano- MOFs have shown enhanced properties compared to their bulky crystallites owing to greater mass transport rates in MOF-pores which rendered in higher catalytic activities, improved gas permeability in separation membranes, also superior colloidal stability of nano-MOFs make them competent for drug delivery applications. Therefore, controlled synthesis of MOFs nanoparticles with desirable sizes will pave the way for a myriad of applications, as well as their solution state analysis enables exploration of size-dependent physical and chemical properties.

The so-called ‘Nano-MOFs’ can be synthesized using several techniques such as microwave synthesis, sonochemical synthesis, solvothermal process, microemulsions, and droplet- based microfluid synthesis. Though all these processes depend on the control over nucleation and growth of MOFs crystallites via variation in synthetic parameters such as modulator concentration, temperature, reaction volume, time, etc.
The aim of the project is the explore the MOF synthesis strategies in nano dimension. In doing so, this project seeks to develop design strategies of nano-MOFs and their potential applications. The project will include the experimental preparation and characterization of the nano-MOF materials by XRD, DLS, TEM, etc.
