How do multiwalled carbon nanotubes (MWCNTs) affect the microstructure and properties of cement paste under thermal loading?

MSAGroup members Maciej Szeląg and Wojciech Franus, with the participation of Patryk Ruminski (PL) and foreign partners Magdalena Rajczakowska and Andrzej Cwirzen from Lulea University of Technology in Sweden, answered this question in a recent paper titled "Macro- and microstructural evolution of cement paste modified with MWCNTs under thermal shock conditions," published in the Journal of Building Engineering (IF = 6.4). The process of thermal evolution of the microstructure of cement paste, and the influence of MWCNTs on this process, was analyzed in detail using techniques such as mercury porosimetry, X-ray diffraction, and scanning electron microscopy. Among other things, it was revealed how the portlandite content changes as a function of thermal loading and the amount of non-hydrated portion of the cement at different MWCNT contents.

Sonata 19 – a new project by the National Science Centre for MSAGroup

The project titled “MagZEObone: Smart Magnetic Biomaterials Based on Zeolites and ZIFs in Service of Humanity - Multifunctional Bone Healing and Regeneration” has received funding in the Sonata 19 competition. The aim of this project is to develop innovative magnetic biomaterials based on zeolites and zeolite imidazolate frameworks (ZIFs) as a multifunctional bone healing and regeneration tool. These biomaterials will respond to static magnetic fields to enhance bone tissue regeneration. We aim to develop material solution to the problems of modern biomedicine. Combining the chemistry, biology, engineering and medicine will allow our team to look at the picture from a bigger perspective: synthesizing the novel materials by means of chemical methods, modifying its properties with biopolymers and chosen drugs for a sustained release, optimizing the process parameters of each part of the project, biological characterization, and in the end medical application. Therefore, we will obtain specialized chemical and biological knowledge, that could be useful to solve the real-life problems.

Jakub Matusiak (PI) and Wojciech Franus are involved in the project's implementation. The project partner is Agata Przekora-Kuśmierz from the Medical University of Lublin.
