In this work, compositions containing transparent glass bottles and banana leaves (desiccated crushed), with different mass fractions (30-50%), were prepared for obtaining cellular materials thermal insulation purposes. The formulated uniaxially pressed (10 MPa) the compact powders fired between 700 850°C 30 min in order to investigate effect of on formation pores mechanical properties processed foams. results indicated that obtained foams porosities 58.5 87.5%, compressive strength ranging...
Photocatalytic processes are an efficient and important technique to mineralize organic contaminants in aqueous effluents. However, it is paramount that there a way recover the catalyst after degradation. Based on this problem, research seeks evaluate photocatalytic properties of TiO2 under porous ceramics support for degradation Rhodamine B (RhB). was synthesized by sol-gel, dried at 100 °C calcined 400 °C. The morphological, optical structural proprieties particles were characterized. XRD...
For the first time, cobalt ferrite spinel (CoFe2O4) was used as a catalyst in Fenton process for Remazol Red RR dye degradation water. CoFe2O4 synthesized via gel combustion using tris(hydroxymethyl)aminomethane an alternative fuel one step with ratio of Ψ = 0.8. Its structural, surface optics, magnetic properties, and optimal conditions reagents were evaluated. The saturation magnetization remanence (Ms Mr, respectively) as-prepared powder 65.7 emu/g 30.4 emu/g, respectively, coercivity...
Polylactic acid (PLA) and hydroxyapatite (HA) composite scaffolds have been widely studied for applications in bone tissue engineering (BTE) due to their bioactive biocompatible properties. However, there is a need more knowledge about the influence of size crystallinity HA nanoparticles (nHA) on properties PLA/nHA nanocomposite produced by 3D printing. In this study, printing was used produce PLA incorporated with nHA filler different particle sizes crystallinities. Initially,...
ABSTRACT Polycaprolactone (PCL) electrospun fiber mats containing varying concentrations of graphene flakes (GF), hydroxyapatite (HAp), and with niobium pentoxide (HAp5Nb) were successfully prepared by electrospinning. These composites exhibit great potential in biomedical applications, particularly as scaffolds for bone tissue engineering. The addition GF enhances the rheological properties PCL solution due to intrinsic resulting from their interactions. Additionally, incorporating HAp...
Alumina is one of the most studied and used ceramic materials, but increasing its fracture toughness still a challenge for many specific impact applications. Adding second phase with low coefficient thermal expansion (CTE) to an alumina matrix can enhance matrix's mechanical properties, reduce sintering temperature, increase by generating compressive stresses on particle surface. In this study, nanostructured alumina/eucryptite composites were prepared achieve enhanced toughness. First,...
The use of 3D bioprinting techniques for scaffold production represents an innovative approach, enabling the development biomimetic structures that serve as matrices new tissue formation. This study investigated influence varying nanohydroxyapatite (nHA) particle sizes on properties PLA/nHA scaffolds. results obtained from nanocomposites containing 3% wt. nHA indicated size does not significantly affect surface morphology, mobility, thermal behavior, handling, or cytotoxicity in analyzed
