Gecko-Inspired Adhesive Pull-Off Tests on Heritage Surface Materials

Two types of gecko-inspired dry adhesives were assessed using pull-off tests on three substrate materials based on real heritage objects. Adhesive strength varied between the flat-tip and mushroom-tip adhesives and reduced with increased substrate roughness. Finite Element Modelling of the tests closely matched empirical results, showing microscale behavior on rough surfaces.

Geopolymer Specimens from LD and LF Steel Slag with KOH Alkaline Solution

A study by Ana Paula Pereira investigated geopolymers synthesized from Linz Donawitz (LD) and ladle furnace (LF) steelmaking slags using an 8M potassium hydroxide solution. Specimens were produced at three solid/liquid ratios (1.2, 1.4, and 1.6 g/v) and analyzed via XRF, FTIR, TGA, SEM-FEG, and Archimedes' principle. The results indicated that the 1.6 ratio samples exhibited more cohesive appearance and higher densification.
