Special Issue Information

Dear Colleagues,

Clean water is a vital component in the lives of humans, plants, animals, and the survival of our ecosystem. Worldwide, contaminated water has been a major concern due to rapid technological and industrial growth. Meanwhile, the steady rise in population around the globe requires access to clean water whether for human consumption, food production, industrial use, or other applications. The presence of water contaminants (organic pollutants, inorganic pollutants, emerging contaminants) in various water bodies has detrimental effects on both human health and the environment. At present, commercial technologies available in water and wastewater treatment remain costly to operate and maintain. The Special Issue will present research, especially basic studies, laboratory studies, pilot studies, or engineering practices, that will discuss the application of sustainable materials in bioengineering technologies and water treatment technologies.

This Special Issue of Sustainability will focus on the present (especially advanced) technologies for water and wastewater management and treatment using sustainable materials such as biopolymers, agricultural wastes, organic solid wastes, industrial by-products, etc., that are applied in treatment technologies including ion exchange, coagulation and flocculation, membrane technology, aerobic and anaerobic bioreactors, and chemical precipitation, to name a few. This issue welcomes the submission of review papers, short communication and regular research articles. Abstracts in conference proceedings in line with this theme can also be submitted to this issue.

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. Sustainability 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 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.

Bone materials are mainly composed of an inorganic constituent called hydroxyapatite (HA). In the current study, mesoporous Zn2+/Ag+ doped hydroxyapatite nanoparticles (Zn-Ag doped HA) with high antibacterial activity were synthesized through ultrasonic coupled sol-gel techniques under calcination temperatures of 600 °C for 4 h and 1100 °C for 1 h. The variance in the molar ratio of Zn2+/Ag+ in Ca9.0Zn1.0−xAgx(PO4)6(OH)2 (x = 0.0, 0.25 to 1.0) and its effects on the chemical and physical properties of the powdered samples were investigated. The results show that the hexagonal framework of HA incorporated both the Zn2+ and Ag+ ions and the rhombohedral structure of β-TCP. The main functional groups of HA and Zn-Ag doped HA samples were hydroxyl and phosphate. All samples have mesoporous characteristics with a Type IV isotherm. The agar well diffusion process was used to examine antibacterial activity against E. coli, P. aeruginosa, S. aureus, B. cereus and B. subtilis. Effective antibacterial activity was displayed by Zn-Ag doped HA. Excellent antibacterial performance was shown by Ca9.0Zn0.75Ag0.25(PO4)6(OH)2 against all tested bacterial strains, except P. aeruginosa. This material showed inhibition zones ranging from 7 to 11 mm, implying that it is a suitable material with an antibacterial action for environmental applications, specifically for water purification.
