Silica clay (opoka) as a promising raw material for unfired wall products by compression molding

Potential of Marine Clay as Raw Material in Geopolymer Composite

In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate proportion of alkaline activator could have strength requirements for masonry cement. The alkaline activator that been used for the geopolymerisation reaction is sodium silicate and...

Camphor as a promising insecticude for control

Eucalyptus globulus Stumpwood as a Raw Material for Pulping

In this study, Eucalyptus globulus stumpwood samples collected from six different sites in Portugal were evaluated for their ease of pulping, using two delignification processes (kraft and alkaline sulfite-anthraquinonemethanol (ASAM)). Morphologically, the stumpwood included fibers with a mean length of 0.930 mm, diameter of 21.4 μm, lumen width of 9.1 μm, and cell-wall thickness of 6.1 μm. Th...

Graphdiyne as a promising material for detecting amino acids

The adsorption of glycine, glutamic acid, histidine and phenylalanine on single-layer graphdiyne/graphene is investigated by ab initio calculations. The results show that for each amino acid molecule, the adsorption energy on graphdiyne is larger than the adsorption energy on graphene and dispersion interactions predominate in the adsorption. Molecular dynamics simulations reveal that at room t...
