Examination of alkali-activated material nanostructure during thermal treatment

Utilization of Mineral Wools as Alkali-Activated Material Precursor

Mineral wools are the most common insulation materials in buildings worldwide. However, mineral wool waste is often considered unrecyclable because of its fibrous nature and low density. In this paper, rock wool (RW) and glass wool (GW) were studied as alkali-activated material precursors without any additional co-binders. Both mineral wools were pulverized by a vibratory disc mill in order to ...

Effect of Concentration and Thermal Treatment on the Properties of Sol-Gel Derived CuO/SiO2 Nanostructure

Various concentrations of copper are embedded into silica matrix to xerogel form using copper source - Cu(NO3)2∙3H2O. The xerogel samples are prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method  and with determination of new molar ratio of components H2O/TEOS to be 6.2. In this investigation, the necess...

Release of alkali metals during biomass thermal conversion

Biomass is material derived from living or recently living organisms and is a potential source of energy with very specific properties. Biomass has great potential to replace fossil fuels in energy systems, offering environmental benefits due to its carbon neutrality and renewability. However, the firing and co-firing of biomass can lead to problems such as slagging, fouling and metal corrosion...

Mining Images of Material Nanostructure Data

Scientific datasets often consist of complex data types such as images. Mining such data presents interesting issues related to semantics. In this paper, we explore the research issues in mining data from the field of nanotechnology. More specifically, we focus on a problem that relates to image comparison of material nanostructures. A significant challenge here relates to the notion of similar...
