The synthesis and magnetic characterization of pegylated bis(aminoxyl) diradical with an S= 1 ground state are presented, revealing water-induced changes in the molecular conformation and magnetic properties.
conclusions by a simple check of the water peak characteristics, lots of information can be obtained, one of which is the status of shimming that has a considerable effect on the accuracy of the spectrum. thus, performing an automatic or manual shimming is not a criterion of the spectrum accuracy, and performing a periodic quality control using a test phantom by a specialist is necessary. brief...
Background: Lead (Pb) is a heavy metal that is widely utilized in industries. It contaminates soil and groundwater. Its non-biodegradability, severe toxicity, carcinogenicity, ability to accumulate in nature and contaminate groundwater and surface water make this toxic heavy metal extremely dangerous to living beings and the environment. Therefore, technical and economic methods of removing Pb ...
in the present research mixed convection flow through a copper-water nanofluid in a driven cavity in the presence of magnetic field is investigated numerically. the cavity is heated from top and cooled from bottom while its two vertical walls are insulated. the governing equations including continuity, n-s and energy equations are solved over a staggered grid system. the study is conducted for ...
