The aim of IIWEnNan special issue was to compile discussions regarding the aspects related to the environmental applications of Nanotechnology presented during the II Workshop in Environmental Nanotechnology, as well as the methods and techniques to the study of nanoparticles in the environment.

Application of Nanomaterials in Environmental Improvement

Nanotechnology has become increasingly a reality nowadays, and along with it there is a need for discussions related to potential advances, as well as the impacts on the environment and human health that technology can cause Purohit et al.

Nanomaterials applications and also implications on the environment have been studied by several groups around the world, and particularly in Brazil, where nanotechnology has been increasingly applied on agriculture and their impacts are still unknown. In this context, the II Workshop in Environmental Nanotechnology was an interdisciplinary forum of discussions about the aspects of this new technology, as well as, its innovation in the environmental area, contributing to the education of undergraduate and graduate students and also as an interchange and exchange of experiences among the invited speakers, professors, researchers and students of several post-graduation programs, contributing to the generation and spreading of knowledge in the environmental nanotechnology area.

The aim of IIWEnNan special issue was to compile discussions regarding the aspects related to the environmental applications of Nanotechnology presented during the II Workshop in Environmental Nanotechnology, as well as the methods and techniques to the study of nanoparticles in the environment. Besides, it will approach some aspects related to the toxicity of the nanomaterial and its possible impacts on the environment.

In this context, the present special issue will be a forum on spread of knowledge and improvement for researchers, professors and undergraduate and graduate students from this research field. In this special issue, we invited the participants from the Workshop to submit manuscripts in the following types: original full-length research articles, short communications, mini reviews, reviews, case studies, meta-analysis and perspective articles.

Among their diverse applications, nanomaterials have been used for decreasing the toxicity of agrochemicals to non-target organisms Grillo et al.

In addition to nano-based systems, others materials can be employed as molecular carriers for agrochemicals, such as the cyclic oligosaccharides cyclodextrins. The study of Venceslau et al. The developed complex was shown to effectively decrease the toxicity of atrazine against lettuce Lactuca sativa seedlings, as demonstrated by the reduction of chromosomal aberrations and nuclear abnormalities in the bioassays in comparison with non-complexed atrazine.

Soda lignin from Citrus sinensis bagasse: extraction, NMR characterization and application in bio-based synthesis of silver nanoparticles. There is an increasing concern regarding the sustainability of the methods used for the synthesis of nanomaterials. Instead of classical chemical methods, green syntheses of nanomaterials have emerged in recent years, with the use of plant extracts, fungi or bacteria in the procedures Sharma et al.

The study of Barros et al. After full sequential extraction, the obtained soda lignin was characterized by nuclear magnetic resonance and then used for the successful production of highly stable silver nanoparticles. Thus, this study is a successful example of how a renewable material extracted from agroindustrial waste can have nanotechnological applications.

Protein oxidation in the fish Danio rerio Cyprinidae fed with single- and multi-walled carbon nanotubes. The increasing development of nanotechnology is paralleled with the concern about the risk of environmental contamination with nanomaterials Kah ; Sadeghi et al. Thus, research is necessary to address the potentially toxic effects of different types of nanomaterials on model organisms and to establish safety and regulatory protocols.

Seixas et al. The data showed high levels of protein carbonylation in many fish organs in response to carbon nanotube exposition, demonstrating the induction of oxidative stress by this nanomaterial in an aquatic organism.

The importance of nanotoxicological in vivo studies using alternative models other than mammalians is discussed by Avila et al. The minireview reports diverse nanotoxicological studies employing alternative models, such as the above-mentioned zebrafish, the nematode Caenorhabditis elegans , the Drosophila melanogaster , and the microcrustaceans Artemia salina and Daphnia magna. In this context, this topic is important to promote a discussion regarding the safety of nanomaterials to organisms that can be used to assess environment pollution and to predict effects in more complexes animals, as well as to the establishment of regulatory frameworks.

Notably, the special issue IIWEnNan—Workshop in Environmental Nanotechnology has selected key topic papers that give to the readers a good overview about the importance of the discussions in the field of environmental nanotechnology.

Effects of Nanoparticles on the Environment and Outdoor Workplaces

In recent years, researchers used many scientific studies to improve modern technologies in the field of reducing the phenomenon of pollution resulting from them. In this chapter, methods to prepare nanomaterials are described, and the main properties such as mechanical, electrical, and optical properties and their relations are determined. The investigation of nanomaterials needed high technologies that depend on a range of nanomaterials from 1 to nm; these are scanning electron microscopy SEM , transmission electron microscopy TEM , and X-ray diffractions XRD. The applications of nanomaterials in environmental improvement are different from one another depending on the type of devices used, for example, solar cells for producing clean energy, nanotechnologies in coatings for building exterior surfaces, and sonochemical decolorization of dyes by the effect of nanocomposite.

Ecotoxicity of Nanoparticles

Sachindri Rana, P. Nanotechnology is a science of producing and utilizing nanosized particles that are measured in nanometers. The unique size-dependent properties make the nanoparticles superior and indispensable as they show unusual physical, chemical, and properties such as conductivity, heat transfer, melting temperature, optical properties, and magnetization. However, the safety of nanomaterials is of high priority.

Беккер с трудом приподнял голову. Неужели в этой Богом проклятой стране кто-то говорит по-английски. На него сверху вниз смотрел прыщавый бритоголовый коротышка.

Немец лежит в постели и ждет. Самый крупный мужчина из всех, с кем ей приходилось иметь. Нарочито медленно она взяла из ведерка кубик льда и начала тереть им соски. Они сразу же затвердели. Это было одной из ее многочисленных хитростей: мужчинам казалось, что она сгорает от страсти, поэтому они стремились прийти к ней снова и .
