Special Issue Information

Dear Colleagues,

This Special Issue focuses on recent advancements in the design and characterization of nanostructured materials, aimed at enhancing the understanding of their structure–property relationships and applications across various scientific and industrial fields. Nanostructured materials are defined as materials with at least one dimension of their building blocks measuring less than 100 nm, which imparts unusual physical properties that differ from those observed at the macroscale. They have already been used in electronics, medicine, biology, sensors, catalysis, and spectroscopy. They are used in the form of nanoclusters, nanocrystals, colloids, composites, or thin films. Precisely characterizing these materials to understand the structure-related properties is essential to further functionally developing and designing of these materials. We are looking to understand the interactions between the sizes, morphologies, and surfaces of nanomaterials and their properties. Therefore, for the upcoming Special Issue, we would like to ask you to present your latest studies on the design and characterization of different types of nanostructures.

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.

Polydispersed Ag species-modified TiO2 samples with abundant oxygen vacancies were successfully prepared through the calcination of atomically precise Ag33 nanocluster-loaded TiO2 at an optimal temperature under a nitrogen atmosphere. The ligands of the Ag33 nanoclusters are removed by extracting lattice oxygen from TiO2 during the calcination, leading to the formation of CO2, SO2, and H2O vapor. This process simultaneously induces Ag species sintering on the surface of TiO2. The resulting nanocomposites exhibited excellent catalytic activity for the reduction of nitroarenes with NaBH4 as the reductant. This is attributed to the produced Ag species on the oxygen-deficient TiO2, which act as active centers for the catalytic process. Full article
