Sub-nanometer silver clusters that exhibit discrete electronic structure with molecular-like properties are highly desirable in various technologies. However, the methods for their preparation suffer from limitations related reproducibility and particles uniformity and/or possibility of scale-up. Another critical drawback is free sub-nanometer tend to aggregate into larger particles. In this work, a new approach successfully overcomes above developed. It allows, first time, an ultrafast high...
Nowadays there is an increasing demand of natural antioxidants. Imbalanced production and consumption reactive oxygen species, lead to many diseases such as cancer, arteriosclerosis ageing processes. The protective effects plants have long been attributed their antioxidant compounds, like polyphenols, flavonoids, carotenoids, vitamins C E. Therefore, the present study was designed evaluate activity tannins crude methanolic extracts Aristolochia clematitis L. by two complementary test systems...
Volcanic clay from Aïn Ouarka south west of Algeria (CA) was used to remove malachite green (MG). This material purified and sodified (CA‐Na + ). They were characterized by different analysis techniques such as BET, SEM, XRD, ATG‐ATD, FTIR, the cation‐exchange capacity (CEC). Batch adsorption tests performed examine effect several parameters contact time, pH solutions, initial concentration, temperature. The present study is first be carried out hitherto regarding natural clay, where...
Abstract Research and scientific work continue to develop low-cost treatment processes in terms of improving water quality environmental protection. Oxide zinc supported natural clay is synthesized by impregnated method. The role this modification increase the adsorption capacity a basic dye (Methylene Blue) compared with calcined clays. These samples are characterized several analytical methods, X-Ray Diffraction (XRD), Thermogravimetric Analysis/Differential Thermal Analysis (TGA/TDA)...
