SAP inside concrete creates additional voids which, in general, lessens concrete strength but improves the workability and consistency, reduces the concrete susceptibility to freezing thawing cycle, and thereby improves concrete stability beneath such situation. Addition of super plasticizer additionally improved the overall workability of the…[Read more]

We describe a technique for preserving the higher sediments of fragile sediment cores during transport from area sites and assess potential effects on subsequent laboratory analyses. This methodology addresses the necessity to reduce disturbance to the surfaces of unfrozen sediment cores used for paleoenvironmental or different high-resolution…[Read more]

Cu NPs were synthesized at a concentration of copper salt equal to 2.5, 5, and 10 mM, and at a molar ratio of copper ions and monomeric unit of polyacrylate equal to 1:2. The as-ready Cu NPs have diameters of about 2.5-3 nm for copper concentrations of 2.5 and 5 mM, and 6 nm for copper focus of 10 mM. You probably have by chance inhaled or…[Read more]
