INNOVATIVE SURFACE TREATMENTS FOR BIOMIMETIC ALUMINA SCAFFOLDS IN BONE REGENERATION

In the intricate domain of biomaterials, ceramics emerge as promising long last alternatives in clinical applications, unyielding, yet remarkably adaptable. Among these, alumina ceramics stand as profound potential. Composed primarily of aluminum oxide, these ceramics have captivated the imaginations of researchers and clinicians alike. In this talk, we will present recent research that introduces a novel procedure for the bioactivation of alumina-based porous ceramic constructs, specifically designed to mimic the structural and mechanical properties of human cortical bone [1]. By incorporating wollastonite and applying an acidic surface treatment (piranha solution), we achieved constructs with adequate pore size and interconnectivity. Uniaxial compression tests revealed that as the wollastonite content increased, the Young’s moduli and compressive strength decreased. Importantly, our study demonstrated that increasing wollastonite content significantly enhanced the proliferation rates of bone-marrow-derived mesenchymal stem cells, without any observed cytotoxic effects. These findings position our bioactivated alumina-based porous ceramics as promising materials for practical bone tissue engineering applications.

DEVELOPMENT OF APATITIC NANOMATERIALS FOR INCREASING THE QUALITY OF LIFE

The research focuses on the development of new apatitic nanomaterials with practical application in increasing the quality of life. For more than a decade, our group proposed, in different research projects, the application of tuned-properties apatitic materials in different areas, intended for increasing the quality of life. As such, different types of materials and composites were developed and their potential use in the protection of cultural heritage artifacts, in the development of antimicrobial composites or in environmental protection (particularly for water treatment) was evaluated. In time, the technology readiness levels of the proposed solutions was increased, reaching pilot-scale demonstrators, or even real-life application. All the obtained results demonstrate the tremendous potential of this type of materials to be used in daily applications, as well as their versatility for different types of applicaiton..

WASTE TO ENERGY: A NEW APPROACH FOR SUSTAINABLE WASTE MANAGEMENT

The exponential increase in greenhouse gas emissions associated with municipal solid waste (MSW) disposal in recent decades is primarily attributed to the heavy reliance on conventional landfilling methods. This trend correlates closely with ever increasing population growth and shifts in human lifestyles. Conventional landfilling requires significant land area for landfill cells, leading to the release of untreated leachate into nearby water bodies and unsustainable emissions of landfill gases. Therefore, transitioning to cleaner, more efficient, and environmentally sustainable waste treatment technologies is advisable. Currently, gasification, incineration, pyrolysis, and anaerobic digestion are the most prominent waste treatment methods globally. However, their effectiveness varies depending on the waste composition and quality, making it challenging for end-users to fully grasp their efficacy. To address this issue, it is crucial to establish high-tech waste-to-energy facilities that can meet specific waste compositions of the local area. However, identifying revenue streams for these technologies is challenging for the return of investment and the need to comply with strict local regulations, resulting in increased operational costs. Thus, stakeholders must carefully evaluate the optimal waste treatment approach. In tropical climates, a significant portion of MSW comprises organic matter, primarily from food waste, accounting for up to 45% of total waste components. Additionally, it is estimated that over 25% of recyclable materials are improperly disposed of in landfills, reducing their intended lifespan. Therefore, employing advanced technology for the pre-treatment of both organic and inorganic MSW components is recommended.
