Summary: This study investigated the feasibility of recycling ceramic polishing waste (CPW) in porcelain tile production and its impact on the phase composition, microstructure, and properties of the ceramic body. It was found that high CPW content can promote liquid phase formation at low temperatures, but may cause foaming or expansion at high temperatures, reducing mechanical properties. Successful preparation of porcelain tiles with CPW content of <= 30 wt% at firing temperatures of 1125-1200 degrees C was achieved, providing valuable insights for CPW utilization.

Summary: This study investigated the synergic effect of atmospheric pressure plasma and silane coupling agent on the adhesion improvement of carbon fiber reinforced thermoplastic polymer (CFRTP). The results showed that the plasma/mercapto-silane-treated CFRTP demonstrated a remarkable increase in adhesion strength compared to untreated CFRTP. The analyses revealed that the formation of C-O and Si-O-Si linkages contributed to the improved adhesion strength. Moreover, the combination of both treatments resulted in the creation of a macro-network at the CFRTP/adhesive interface, leading to a substantial increase in adhesion strength. Guidelines for enhancing the adhesion strength of CFRTP were proposed.

Summary: In this study, the idea of synthesizing conjugated polymers (polyaniline, PANI) within the core of a core-shell submicron electrospun fiber was tested. The shell of the fiber was prepared through photopolymerization during electrospinning, while the core was produced from an aniline-rich solution. Polymerization of aniline occurred during electrospinning, leading to the formation of highly doped and conductive emeraldine PANI. The ability of the fiber shell to swell in water and create materials with low elastic modulus, similar to hydrogels, was also observed.

Summary: In recent years, the use of polycaprolactone/silk (PCL/S) blend micro/nanofibers for biomaterial applications has been explored due to their beneficial combination of biodegradability, biocompatibility, and bioactivity. However, the conventional form of these fibers (mats) has limited use due to poor mechanical properties. To overcome this issue, nanofiber yarns (NF-Ys) have been fabricated, combining the advantages of nanofibers with superior mechanical properties. This paper investigates the production of PCL/S NF-Ys by electrospinning and explores the effect of composition and processing parameters on the morphology, tensile properties, and processability of these nanofibers.

Summary: This study investigated the effects of different concentrations and types of polymer flocculants on the flocculation mechanism of kaolinite-rich mining tailings. The results showed that the flocculation process is directly influenced by the pH of the medium, the isoelectric point of the kaolinite, and the molecular mass of the polymer chains. Aggregation of particles in the acrylamide samples occurred through electrostatic interaction, while in the other samples, it occurred through bridging. Additionally, the grafted acrylamide on the chitosan chain was found to improve the flocculation of kaolin waste.
