Special Issue Information

Dear Colleagues,

Ions in electrolytes, charged fluids and plasmas, their mutual interaction, and their interaction with surfaces and particles are of significant interest in chemistry, biology, and physics with a plethora of applications, such as (photo-)catalysis, molecular solar devices, cell biology, and stellar objects subject to gravitational forces.

This Special Issue aims to bring together scientists from interdisciplinary areas in material science with a collection of papers detailing the latest advancements in their respective fields, from low-to-high energy interacting charge systems to the creation of new synergies between these seemingly different subjects.

Possible topics entail ionized fluids, electrolytes including porous ceramics, plasmas and other charged fluids and gases. Special attention will be given to charge interaction, including the efficient description of quantum effects at the atomic level between multiple charges and charge systems. We welcome papers with an emphasis on novel photonic concepts such as soft plasmonics, interacting collective charge oscillations analogous to electrons in solid metal, and biomimetics, the mimicking of biological functions such as photosynthesis in artificial leaves. We also invite work on the characterization of such systems and novel theoretical models, e.g., for the investigation of the communication among nerve cells and the energy transfer between electrolyte, gas, and solid interfaces. Additionally, submissions considering organic and inorganic material approaches will be considered.

Topics of interest, including relevant characterization techniques and applications:

  • Ionized fluids;
  • Electrolytes, including porous ceramic materials;
  • Charged plasmas;
  • Soft plasmonics;
  • Biomimetics, e.g., energy transfer in artificial leaves;
  • (Photo-)catalysis, solar fuel cells and (molecular/organic/dye-sensitized) solar cells;
  • Biological systems, e.g., nerve cell communication;
  • Astrophysics, gaseous clouds, nebulas, etc.;
  • Fusion.

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. Photonics 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 2400 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Plasmonics is the study of resonant oscillations of free electrons in metals caused by incident electromagnetic radiation. Surface plasmons can focus and steer light on the subwavelength scale. Apart from metals, plasmonic phenomena can be observed in soft matter systems such as electrolytes which we study here. Resonant charge oscillations can be induced for ions in solution, however, due to their larger mass, they are plasmon-active in a lower frequency regime and on a larger wavelength scale. Our investigation focuses on spatial confinement which allows increasingly strong charge interactions and gives rise to nonlocality or spatial dispersion effects. We derive and discuss the nonlocal optical response of ionic plasmons using a hydrodynamic two-fluid model in a planar homogeneous three-layer system with electrolyte-dielectric interfaces. As in metals, we observe the emergence of additional longitudinal propagation modes in electrolytes which causes plasmonic broadening. Studying such systems enables us to identify and understand plasmonic phenomena in biological and chemical systems. Full article
