Special Issue Information

Dear Colleagues,

Porous materials are found in all classes of materials, from microporous zeolite ceramics to mesoporous metals, to macroporous polymers.

As a matter of fact, porosity, either closed or open, is a characteristic that strongly defines the properties of a given material, such as its density, specific surface, specific mechanical properties, thermal conductivity, acoustic impedance, and even its permeability to gases and liquids. A properly engineered porous material, for instance, can provide the same performance as its bulk counterpart, but for a fraction of the weight, which is crucial for its application in automotive aerospace fields.

Porous materials based microdevices and micromachines could potentially solve some of the most urgent technological challenges of the modern world, while they are fundamental in a diverse range of applications, from structural materials to energy technologies. Recent advances in porous materials based micromachines include the development of nanoporous metals by selective dissolution and their use in catalysis, and phase separation methods to make porous ceramics. This Special Issue of Micromachines will be devoted to exploring the wide range of types and applications of porous-materials-based microdevices.

Special emphasis will be devoted to novel designs, new fabrication methods, new properties, and new applications, control, and modeling of porous materials based microdevices/micromachines, and how these impact many different technologies.

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 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.

In this work, a screen-printing method was developed to create porous particle-based materials as layers with specifically designed shape to produce microfluidics systems. Among several tested binding agents, xanthan gum was found to be an excellent choice for a printing mixture thickener as well as a durable binder for the resulting material. In addition to demonstrating control over the shape of the printed microfluidics chips, control over material thickness, wetting characteristics and general method accuracy were also investigated. The applicability of the introduced method was further demonstrated with a development of an exemplary microfluidics chip for quantitative detection of Fe (III), Ni (II), Cu (II), Cd (II), and Pb (II) from a mixed sample at millimolar levels. The novel approaches demonstrated in this article offer new perspective into creating multiplexed on-site chemical analysis tests. Full article
