Special Issue Information

Dear Colleagues,

Following the success of the first edition, this Special Issue will serve as a comprehensive overview of the latest advances and innovative research in the field of colloids and interfaces from Asia, but contributions from researchers outside Asia are also welcome.

This Special Issue will cover a wide range of topics including, but not limited to, experimental and theoretical aspects of interfacial phenomena, the fabrication and characterization of colloidal systems, properties of solutions of surface-active molecules, self-assembling and aggregation in solution and at interfaces, fluid dynamics, applications of colloids and interfacial aspects in biology, medicine, cosmetics, food and material science and new emerging directions in colloid and interface science. Through original research articles, reviews and short communications, this Special Issue will provide significant insights into the state-of-the-art methods and technologies being developed by Asian researchers.

Contributions from leading academic institutions, research centers and industry experts will enhance the diversity and universality of collected articles. This Special Issue will expand perspectives, inspire innovation and promote cooperation for the research of colloids and interfaces.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Colloids and Interfaces 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 1700 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.

We conducted a theoretical analysis on the diffusiophoretic motion of a dielectric droplet in a cylindrical pore in the presence of an induced diffusion potential, such as that in a NaCl electrolyte solution. The fundamental electrokinetic governing equations are solved using a patched pseudo-spectral method based on Chebyshev polynomials, coupled with a geometric mapping scheme to handle the irregular solution domain. The impact of the boundary confinement effect on droplet mobility is examined in detail. Interesting electrokinetic phenomena are found in this work, such as mobility reversal in narrow cylindrical pores with the droplet moving against the direction expected based on the classical Coulomb electrostatic law due to the strong boundary confinement effect. Moreover, “solidification phenomenon” is also found at some specific pore radius where the droplets move as rigid particles with no interior recirculating vortex flows regardless of the droplet viscosities. Corresponding critical points of Rw*, the ratio of droplet radius to the cylindrical radius are found where the spinning orientation on the droplet surface changes each time as it passes them. The profound boundary confinement effect, both electrostatically and hydrodynamically, is responsible for these peculiar phenomena. The results presented here have direct applications in microfluidic and nanofluidic operations as well as drug delivery applications. Full article
