Special Issue Information
Dear Colleagues,
Nanomaterials are materials designed at the molecular nanometre level to take advantage of their smaller size and novel properties which are generally not seen in their conventional micro state counterparts. The physico-chemical properties of nanomaterials can change compared to those of the micro size such as e.g. the ability to conduct electricity, the strength characteristics and the magnetism. These differences of properties are based on two main reasons, the increasing of the relative surface area and the new quantum effects. At nano-scale, materials have a much greater area to volume ratio then their micro size which increase the chemical reactivity and their strength. In addition, the quantum effects can become much more important in determining the materials characteristics, leading to new properties.This special issue of Nanomaterials will be devoted to the emerging field of Composite Nanomaterials. In the last few years, nanocomposites have evoked a lot of interest. Their potential in research, industry and to the community have been highlighted and demonstrated in several studies, articles and reports. The polymer nanocomposites are based on organic polymer and inorganic nanoparticle; these composites have attracted increasing attention because of their unique properties emerging from the combination of organic and inorganic hybrid materials. By combining the attractive functionalities of both components, and the nanostructure of the particles, nanocomposites are expected to show new and improved properties. The potential applications of the resultant nanocomposites are various, e.g., biomedical, automotive, sensors, opto-electronics, etc.
The scope of Nanomaterials aims to cover recent progress in nanocomposites; particular attention will be given to new contributions in the field of characterization and applications of nanocomposites. Nanomaterials Special Issue (ISSN 2079-4991) call for new contributions in the field of nanocomposites and will give direct access to the most recent information in this field.

Submission
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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Abstract: Magnesium is actively used as a lightweight metal in the aerospace and automotive industries. It is 35% lighter than aluminium and 78% lighter than steel. Its use ensures lower fuel consumption, reduced CO2 emissions and thus a greener earth. Magnesium is also used as a lightweight metal in the consumer electronics and sports industries, replacing plastics. Here, the superior electromagnetic shielding and vibration damping characteristics of magnesium contribute to better health and well-being of the human body. This also leads to better quality of life globally. The multiple beneficial effects of Al2O3 nanoparticle addition to cast magnesium based systems (followed by extrusion) are investigated here. They are either: (a) enhanced ductility or (b) simultaneously enhanced strength and ductility of the corresponding magnesium alloys. The capability of Al2O3 nanoparticles to enhance the properties of cast magnesium alloys in a way never seen before with micron length scale reinforcements is clearly demonstrated.
