Master Thesis: Fabrication of porous biomimetic 3D hybrid scaffold for bone tissue engineering
Master's thesis on fabrication of bio-mimetic porous inorganic-organic hybrid materials for bone tissue engineering is offered to highly motivated students.
Bone tissue engineering (BTE) is an alternative approach to current therapies available for severe bone defects with poor manifestations of self-regeneration. Accomplishment of BTE needs three-dimensional (3D) templates (scaffolds) of appropriate morphology and chemical characteristics to imitate the extracellular matrix (ECM) and allow cells to migrate, attach, grow, proliferate, and differentiate.
In this project, the focus is to develop a series of multi component antibacterial porous 3D scaffold constructs through combination of bio-inspired processing and microextrusion based 3D printing techniques.
Interested applicants are invited to send their application including CV as well as a cover letter to h.maleki@uni-koeln.de
Please send your application documents as one PDF file

Bachelor or Master thesis opportunity: Pressure sensor based aerogels from assembly of 2D nanomaterials
In this project, the objective is to fabricate multicomponent piezoresistive pressure sensors (PSs) based on elastic nacre mimetic reduced graphene oxide composite foams with ordered porous microstructures through combination of surface modifications, directional freeze casting and freeze drying. Since a highly efficient PS should possess good flexibility, high sensitivity, and fast response, the 3D porous rGO foam architecture with its own pristine properties is difficult to consider as a PS due to its poor elasticity and low sensitivity. Therefore, for conferring high mechanical resilience with reversible compressibility to GO foam but also enhancing the ultimate electerical conductity, the main building block of planned PS, in this project, is palnned to be hybridized with flexible biopolymer but also other electroacive nanosheets through robust covalent linkages. The nacre-mimetic piezocomposite foams with prominent properties is expected for measuring pressure distribution, monitoring healthy activity, but also toward self-powered or ultra-low power consumption applications.
