Nowadays, an important objective for researchers is to find an alternative to build cheaper and greener, sustainable and also durable. To discover a material with better thermal and acoustic performances than conventional concrete by using natural and renewable components in its composition became also an obvious trend. The agriculture products, mainly those considered as waste in this field, fulfill all the above mentioned requirements, being also widely available and with higher thermal and acoustic properties t...

Wear-resistant composite coatings reinforced with Al2O3 nanoparticles (20nm) obtained by electroless technique are analysed in this paper. The structure and surface morphology of coatings with alumina nanoparticles embedded in the Ni-P alloy for different quantities of alumina in the nickel-plating bath (3g/L, 5g/L and 8g/L) are presented. Nanocomposite electroless coatings are characterized by optical microscopy, XRD and SEM. Microstructure of the composites has revealed uniform distribution of Al2O3 nanoparticle...
