Special Issue Information

Dear Colleagues,

The production of advanced materials contributes to driving social and economic development, which in turn demands new materials of target properties to meet specific needs. New materials of strictly defined structure and properties are designed on the basis of the results of fundamental studies. Materials science has been determined by the results of basic research, as the design and production of valuable materials is impossible with no grounds provided by the studies on a molecular level. The main reason for this is that materials science and technologies have become closely related, and the core issue of their development is the discovery and development of innovative, advanced products. The world research work has been focused on the deeper understanding and description of the nature of matter for many years. Studies of matter on a molecular level require the combination of chemical, physical and biological methods. In recent years surfactants have become of increasing interest in the global search for materials of specific properties. Thanks to the characteristic chemical structure, amphiphilic compounds demonstrate interesting features. The most interesting property is their surface activity.

In order to understand the behaviour of these specialist surfactants it is worth, considering the principles that govern this behaviour. In most cases, the useful and fascinating properties of surfactants are essentially the result of combining certain groups that would be incompatible as separate molecules into one molecule.

Thus, the proposed Special Issue of the International Journal of Molecular Sciences will cover the results of studies on the synthesis and properties (also biological) of new synthesized, as well as natural (seminatural) surfactants. Results related to the surface, aggregation and wettability of different solids by specialist surfactant solutions within different conditions and areas are especially welcome.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

In the presented study, the effectiveness of a siloxane polyether (HOL7) coating on glass against microbiological colonization was assessed using microalgae as a key component of widespread aerial biofilms. The siloxane polyether was successfully synthesized by a hydrosilylation reaction in the presence of Karstedt’s catalyst. The product structure was confirmed by NMR spectroscopy and GPC analysis. In addition, the thermal stability of HOL7 was studied by thermogravimetric measurement. Subsequently, the surfaces of glass plates were modified with the obtained organosilicon derivative. In the next step, a microalgal experiment was conducted. A mixture of four strains of algal taxa isolated from building materials was used for the experiment—Chlorodium saccharophilum PNK010, Klebsormidium flaccidum PNK013, Pseudostichococcus monallantoides PNK037, and Trebouxia aggregata PNK080. The choice of these algae followed from their wide occurrence in terrestrial environments. Application of an organofunctional siloxane compound on the glass reduced, more or less effectively, the photosynthetic activity of algal cells, depending on the concentration of the compound. Since the structure of the compound was not based on biocide-active agents, its effectiveness was associated with a reduction in water content in the cells. Full article
