Throughout the last decade, and particularly in 2022, water scarcity has become a critical concern Morocco other Mediterranean countries. The lack of rainfall during spring was worsened by succession heat waves summer. To address this drought, innovative solutions, including use new technologies such as hydrogels, will be essential to transform agriculture. This paper presents findings study th...

the paper is focused on the formation of hydroxyapatite nanoparticles (hap) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. it is shown that paa, can be incorporated into the individual inverse microemulsion droplets. the m...

Improvements in Function with Tiotropium (UPLIFT1) trial [4]. The authors are correct in highlighting the notable differences between the Lung Health Study and UPLIFT1 study populations with respect to age and disease severity. It is of interest, however, that, in the Lung Health Study, a post hoc subanalysis of the annual rates of decline by smoking category (continuing smokers, intermittent s...

A method for preparation of a new stable Cu(I) catalyst supported on weakly acidic polyacrylate resin without additional stabilizing ligands is described. A simple and efficient methodology for Ullmann Cu(I) catalyzed C-N cross coupling reactions using this original catalyst is reported. Coupling reactions of 4-chloropyridinium chloride with anilines containing electron donating (EDG) or electr...

The yield stress-DLVO force relationship is obeyed by α-Al2O3 and alumina-coated TiO2 dispersions with adsorbed polyacrylate only if the yield stress and its corresponding zeta potential data were collected in the positively charged region. In this region, the underlying surface positive charge density of the particles exceeds the negative charge density of the polyacrylate. At this state the a...
