Special Issue Information
Dear Colleagues,
Colloids have been known for centuries and find innumerable applications in everyday life, from the food industry, to medicine, filtering and purification systems, and so on. In 1995, the colloidal suspensions of nanoparticles with the specific purpose of modifying the functional properties of the fluid itself were identified and defined by Choi as “nanofluids”. Since then, studies on nanofluids have multiplied exponentially. Different types of fluids (water, glycols, alcohols, oils, etc.) containing nanoparticles of various metals, oxides, and carbon nanostructures have been studied. Research has begun on the heat transfer and then expanded by investigating other properties and potential applications, including thermal energy storage, pool boiling, wettability, surface tension, lubrication properties, optical properties particularly absorption of solar radiation, magnetic or electric properties, etc.
However, altough the first prototypes or the first commercial scouting begin to appear, some issues still need to be addressed, such as stability over time and in operating conditions or viscosity increase and pressure drop.
This Special Issue will attempt to explore recent advances in nanofluids, focusing on all aspects of their development: the design, from synthesis methods to new formulations; new potential applications and properties investigated; advances in understanding the behavior of nanoparticles and in modeling; and advancement in engineering and industrialization of nanofluids. This Special Issue also aims to investigate the advances on cutting-edge strategies to deal with issues still to be overcome in the nanofluids development. The intent is to give an overview of the progress of research, including different types of fluids, nanoparticles, colloids or emulsions, particularly focusing on energy aspects including heat exchange efficiency, thermal energy storage, lubrication, and in general on the energy efficiency increase of devices.

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.
