Abstract This work presents the results of a preliminary study in which a sodium aluminosilicate geopolymer powder was shaped into a lattice component by additive manufacturing and successfully employed as a structured heterogeneous catalyst for biodiesel production. The processing and the structural characterization of the 3D printed body and the chemical conversion tests are described and discussed.

Abstract MAX-phase (Ti 2 AlC) gel-cast foams manufactured using agarose as gelling agent were investigated in terms of their microstructural, mechanical and thermal properties. The microstructural analysis of Ti 2 AlC foams made using SEM were compared with those using X-ray micro tomography. The Young’s Modulus of Ti 2 AlC foams was determined using the impulse excitation technique. This experimental data was correlated with the Gibson-Ashby, Spriggs and Cross-property relation models. The ther...

Abstract Anisotropic, biomorphic (wood-derived) potassium-based geopolymer (KGP) - biocarbon (C B ) composites with net shape were manufactured by infiltrating KGP slurry into monolithic porous biocarbon (C B ) structures (~77 vol% porosity) derived from pyrolyzing beech wood. About 70% of the pores in the three-dimensional (3D) C B structures were infiltrated by the KGP slurry. Compared to pure KGP, the energy absorption per unit volume in compression loading of the KGP-C B composites was incre...

Abstract The influence of different heating rates as well as different atmospheres on magnesium borate fibers produced by electrospinning was investigated in this work. The green fibers were prepared from sol–gel precursors, using polyvinyl-pyrrolidone (PVP) as processing aid. Crystalline fibers with the typical necklace structure and average diameter in the range 300–500 nm were produced when heating up to 900 °C in air. The main phase detected by XRD analysis was in this case Mg 2 B 2 O 5 . On...

Abstract Geopolymers, possessing a semi-crystalline three-dimensional inorganic network generated by the dissolution and reaction of a solid alumino-silicate source with an activating solution, have attracted increasing attention from both academia and industry because of their unique and favorable characteristics. This review deals with the synthesis, characterization and potential applications of porous geopolymers, realized through different processing routes. Firstly, the processing approach...
