Special Issue Information

Dear Colleagues,

It is generally acknowledged that a current pressing challenge is the development of new materials for environmental applications. In fact, the problem of environmental pollution is one of the most critical issues, determining global warming, extreme weather phenomena, decay of health and loss of human lives, etc. This highly innovative and promising new approach is generated by the necessity of humanity paying attention to water, air, and soil remediation. The materials that reversibly respond to stimuli from environments by changing their properties—so-called smart materials—are particularly promising as potential solutions to global environmental issues.

“Smart Materials in Environmental Science” is a Special Issue dedicated to this new class of materials, emphasizing their applications in environmental protection. Smart materials can minimize environmental impacts, increase energy and material efficiency use, enhance recyclability, etc.

Smart materials are used to develop more cost-effective and high-performance water and air treatment systems. They have been extensively used for treatment, remediation, and pollution prevention. For example, via smart materials, water can be reused, recycled, and desalinized without biological or chemical contamination.

For this Special Issue, the following are some examples of the materials considered: polymers, magnetic materials, adsorbents, nanomaterials applied in diverse fields, membranes, photocatalysts, nano- and mesoporous materials, inorganic polymeric materials (siloxanes, xerogels, geopolymers), thin films, glasses, ceramics, building materials, alloys, coating materials, biopolymers, zeolites and biozeolites, nano-insulation materials, carbon nanotubes, mixed oxides, hydroxyapatite, semiconductors, sensors, etc.

We kindly invite you to submit your research contributions in the form of research articles, communications or reviews for this Special Issue.

Nowadays, metamaterials application enjoys notoriety in fluid decontamination and pathogen annihilation, which are frequently present in polluted fluids (e.g., water, blood, blood plasma, air or other gases). The depollution effect is largely enhanced by UVC irradiation. The novelty of this contribution comes from the significant increase by packing of the total surface of metamaterials in contact with contaminated fluids. Packed metamaterial samples are subjected to UVC irradiation, with expected advantages for implant sterilization and long-term prevention of nosocomial infections over large clinical areas. The novel aspect of the investigation consists of a combination of big and small elements of the metamaterial to optimize the above effects connected with fluids and irradiation. The big elements allow the radiation to penetrate deep inside the fluid, and the small elements optimally disperse this radiation toward deeper regions of the metamaterial. A packing scheme of smaller, in-between large metamaterial spheres and fibres is proposed for promoting enhanced depollution against pathogen agents. It is demonstrated that the total surface of metamaterials in contact with contaminated fluids/surface is significantly increased as a result of packing. This opens, in our opinion, new auspicious perspectives in the construction of novel equipment with high sensibility in the detection and decontamination of microorganisms. Full article
