1. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation
Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.
