Special Issue Information

Dear Colleagues,

In recent years, engineered nanoparticles have had a substantial impact on almost all scientific and technological fields. This growth is undoubtedly boosted by the amazing nature of matter at the nanoscale and its potential applications. Increasingly, the presence of nanomaterials in environmental compartments is a reality with interesting short- and long-term consequences. Fortunately, together with the development of nanotechnology, there is a growth in societal concern surrounding its impact in the workplace and on the environment. An array of materials, methodologies and models is being developed for a comprehensive risk assessment of engineered nanoparticles in different scenarios.

In this Special Issue, we are devoted to sketching the current state of the art in decision-making procedures for engineered nanoparticles in the context of the environment. We are looking for manuscripts encompassing multiple aspects of nanotechnology and its impact on diverse ecosystems, as well as exposure assessment and life cycle analysis. Novel scientific findings on the environmental impact of nanoparticles are welcomed, as well as perspectives on the future development of chemical engineering and environmental sciences.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

There is increasing interest in the environmental fate and effects of engineered nanomaterials due to their ubiquitous use in consumer products. In particular, given the mounting evidence that dramatic transformations can occur to a nanomaterial throughout its product lifecycle, the appropriateness of using pristine nanomaterials in environmental testing is being questioned. Using a combination of transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma-mass spectrometry (ICP-MS), this work examines the morphological and compositional effects of conditions mimicking a typical lifecycle of a nano-enabled product, from the production of the silver nanoparticle (AgNP)-laden textiles, through its use, laundering, and then finally, its leaching and incubation in the wastewater collection system. These simulated weathering conditions showed evidence for the transformation of AgNPs into AgCl and Ag2S. Incubation in raw wastewater had the most dramatic effect on the AgNPs in terms of transformation, no matter what initial weathering was applied to the NPs prior to incubation. However, despite extensive transformation noted, AgNPs were still present within all the samples after the use scenarios. Full article
