Special Issue Information

Dear Colleagues,

The synergistic combination of inorganic and organic components at the molecular level in one material enables unique properties of new materials. The production and structuring of such hybrid materials can only be achieved using mild synthesis methods. Sol–gel as a mild and robust process to form inorganic networks plays a crucial role here. By integrating organic molecules, polymers, and functional groups into inorganic matrices, hybrid sol–gel materials exhibit a remarkable combination of flexibility, durability, and functionality. These materials are revolutionising fields as diverse as optics, electronics, biomedicine, and environmental science but can also lead to more sustainable materials and are thus important for the worldwide transformation to a more sustainable future. This Special Issue of Solids is dedicated to the latest innovations, fundamental research, and diverse applications of hybrid sol–gel materials.

In this Special Issue, you will find current research articles and insightful perspectives from leading experts in the field. We deal with the synthesis methods, the structural characterisation, and the optimisation of the properties of hybrid sol–gel materials, as well as their applications.

Hybrid sol–gel materials are characterised by their ability to bridge the gap between traditional organic and inorganic materials. We hope that this Special Issue stimulates further developments.

You may choose our Joint Special Issue in Molecules or Joint Special Issue in Inorganics.

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. Solids is an international peer-reviewed open access quarterly 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 1000 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.

The influence of the quantity of silanol in an active silicic acid solution (ASAS) on the growth rate of colloidal silica particles was investigated. The quantity of silanol in the ASAS was controlled by varying the acid concentration as a hydrolysis catalyst for tetramethoxysilane (TMOS). As expected, the particle growth rate was confirmed to be a function of the acid concentration in the water used to prepare the ASAS. In addition, when the entire process was conducted under basic conditions to obtain spherical particles, the initial basicity had a secondary influence on the particle growth rate. When a partial process was conducted under acidic conditions to obtain morphologically modified particles, the low acidity was found to have a secondary influence on the particle growth rate. Furthermore, it was clarified that the relative silica deposition rate based on acid-free ASAS could be predicted by assuming the seed particle size at the time it was determined. Thus, a production control system was established for highly purified colloidal silica using ASAS derived from TMOS. Full article
