As a novel functional nanomaterial, Fe3O4 magnetic nanoparticles (MNPs) modified by different surfactants have attracted and are attracting worldwide interest. In this research, we introduced two silane coupling agents to modify MNPs instead of single surfactant achieve complete coating functionalization. The modification mechanism was also explained. Techniques such as TEM, XRD, FT-IR, TG-DSC,...

expansion of urban area is a well-known phenomenon in developing countries with population growth and the migration from villages to cities being two major factors. those factors reduce the influence of efforts to limit the cities boundaries. thus, spatial planners always look for the models that simulate the expansion of urban land-uses, and enable them to prevent unbalanced expansions of citi...

Antifungals have always been considered as one of the astonishing discoveries of the 20th century. This is correct, but the real marvel is the development of antifungal resistance in hospitals, communities, and the environment concomitant with their use. Fungal infections have emerged as an important clinical threat, with significant associated morbidity and mortality.  This study is desig...
