Special Issue Information

Dear Colleagues,

This proposed Special Issue aims to explore the latest advancements in π-conjugated organic materials and their applications in a wide range of devices, including energy, biomedical and environmental technologies. This Special Issue will focus on the diverse properties and versatile applications of π-conjugated organic materials, such as π-conjugated polymers, oligomers, graphene, carbon nanotubes and related compounds.

We seek to cover a broad spectrum of topics, including but not limited to the following:

  • The synthesis and design of novel π-conjugated organic materials.
  • Their fundamental properties and structure–function relationships.
  • Their applications in energy devices, such as solar cells and thermoelectric devices.
  • Biomedical applications, including cell devices and biosensors.
  • Environmental applications for water and wastewater treatment.

By compiling cutting-edge research from experts in the field, this Special Issue aims to provide a comprehensive overview of the latest developments and emerging trends in the study of π-conjugated organic materials and their applications. Researchers, engineers and practitioners interested in materials science, energy technologies, biomedicine and environmental sustainability will find this Special Issue to be a valuable resource for exploring new opportunities and driving innovation in their respective fields.

Dr. Ichiro Imae
Guest Editor

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. Materials 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 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.

Abstract
In this study, the removal performances of a multi-pollutant elimination cartridge system (MPECS) composed of palm shell waste-based activated carbon (PSAC), magnesium (Mg)/silicon (Si)-doped PSAC (Mg/Si-PSAC), and silver (Ag)-doped PSAC (Ag-PSAC) for heavy metals, organic pollutants, and Escherichia coli were investigated. Mg/Si impregnation [...] Read more.
In this study, the removal performances of a multi-pollutant elimination cartridge system (MPECS) composed of palm shell waste-based activated carbon (PSAC), magnesium (Mg)/silicon (Si)-doped PSAC (Mg/Si-PSAC), and silver (Ag)-doped PSAC (Ag-PSAC) for heavy metals, organic pollutants, and Escherichia coli were investigated. Mg/Si impregnation significantly improved heavy metal removal using PSAC by increasing the surface area and adding more sorption sites to the magnesium silicate nanolayer. Fixed-bed column experiments showed that the MPECS column outperformed PSAC and commercial activated carbon (DJAC), with a 1.5 to 2.0 times higher E. coli removal and a higher removal of organic pollutants and heavy metals. The MPECS column, with its disinfection ability and adsorption of heavy metals and organic matter, is a promising system for removing multiple pollutants from rainwater. Full article
