Journal ArticleDOI
Synthesis of silver nanoparticles using natural pigments extracted from Alfalfa leaves and its use for antimicrobial activity
Ahmad Baraka,Sarah E. Dickson,Mohamed Gobara,Gharieb S. El-Sayyad,Mahmoud Y. Zorainy,Mohamed Awaad,Hussien Hatem,Mohamed Mokhtar Kotb,A. F. Tawfic +8 more
TL;DR: In this article, the synthesis and characterization of silver nanoparticles (AgNPs) using natural pigments from plants as reducing agents is presented. And the reduction is suggested to occur, mainly, by chlorophyll a and carotenes.
Journal ArticleDOI
Water Security Assessment Indicators: The Rural Context
TL;DR: This paper concludes with some general remarks on the standards used for evaluation, the reliance upon historical and field data, suggestions for improving the descriptive clarity where it is lacking, and the prospect of these indicators getting used by community members.
Journal ArticleDOI
Dissolution of entrapped DNAPLs in variable aperture fractures: experimental data and empirical model.
Sarah E. Dickson,Neil R. Thomson +1 more
TL;DR: The experimental results provide an indication of the expected dissolution behavior of entrapped NAPLs, while the developed model is a useful tool for characterizing mass transfer rates in variable aperture fractures.
Journal ArticleDOI
Slow gas expansion in saturated natural porous media by gas injection and partitioning with non-aqueous phase liquids
TL;DR: In this article, the authors measured the expansion rate of a single gas cluster in a 1.1 mm sand above a pool of trans-1,2-dichloroethene (tDCE) in small-scale flow cell experiments.
Journal ArticleDOI
Differential transport and dispersion of colloids relative to solutes in single fractures.
TL;DR: This work employed numerical experiments simulating colloid and solute transport in single parallel-plate fractures, using the random walk particle tracking method, to demonstrate that there exists an aspect ratio of the colloid radius to half the fracture aperture, delta(o), where the average velocities of colloids and solutes are similar.
