Dear Colleagues,

The research on nanoscale and microscale phenomena has been becoming especially important since the late 20th century, with the intensively development of different micro systems. These phenomena may be found in traditional industries and highly specialized fields such as bioengineering, chemical and biochemical engineering, micro-fabricated fluidic systems, microelectronics, aerospace technology, micro heat pipes, chips cooling etc. The small-scale phenomena are quite different from those at conventional scale or macroscale. Various interesting phenomena, not visible at macroscale, appear when the characteristic dimension of a flow goes down to micro and nanoscales, as, for example the thermal creep where a gas flows from a cold to a hot side of a microchannel. In addition, at microscale, the ratio of the volume occupied by a flow to a surface around it differs essentially from the same ratio at macroscale. Therefore, the fluid-surface interaction becomes very important and it influences considerably the flow behaviors. New instrumentational methods need to be developed applied to measure the basic physical parameters at microscale. New prediction methods and mathematical models are also indispensable to estimate the behaviors of the governing parameters. The objective of this special issue is to present the recent finding in on the nanoscale and microscale phenomena. All type of manuscripts, experimental and numerical, related to the small-scale phenomena are welcome.

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. Micromachines is an international peer-reviewed open access monthly 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 2600 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.
