In this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (PVA) and N,N'-dimethyl formamide (DMF). The Characterization of the samples were carried out using X-ray diffraction (XRD), Transmission-electron microscopy (TEM) and UV-vis spectroscopy. Absorption spectra of the nanoplates in comparison with that of the ...

reducing wastes in the healthcare processes is crucial for developing a high performance health system. adopted from the toyota production system (tps), the lean concept has emerged in recent years as a way of introducing innovative ideas to improve industrial processes. in the context of health care, lean is considered as a continuous improvement model, which provides healthcare organization t...
