Introduction New bioactive hybrid materials to prevent biofilm-induced biodeterioration are a significant challenge in indoor environments, where contaminants from microbial films compromise structural integrity and contribute air pollution, posing health risks prolonged exposure biological agents. Methods For the first time, diatomaceous earth or diatomite (Dt) was functionalized with quaternary ammonium salt (QAS) biogenic compound, citronellol, develop material (Dt*QC). The hybrids...
During the past decade, necessity of new ecofriendly antifouling pigments was established. Among these pigments, special attention should be paid to tannin and its derivatives. Tannins are synthesized by plants as part their defense mechanism against attack pathogens. The objective this work study efficiency paints containing zinc "tannate" in artificial seawater. precipitated at pH 4 8. Insoluble soluble matrix paints, with different plasticizers, were formulated tannins leached from...
Fungi grow especially in dark and moist areas, deteriorating the indoor environment causing infections that particularly affect immunosuppressed individuals. Antimicrobial coatings have as principal objective to prevent biofilm formation by incorporation of bioactive additives. In this sense, metallic nanoparticles, such silver, proven be active against different microorganisms specially bacteria. Biosynthesized method is a promising environmentally friendly option obtain nanoparticles. The...
Zirconia is a widely used multifunctional material. Its interesting properties, such as high chemical resistance, thermal stability and mechanical toughness, have turned this material into object of study within fields optics, electronics, magnetism, among others. In recent years, the properties zirconium oxide been used, mixed with silicon, in order to obtain more stable robust oxides, final application toughening ceramics. These are related degree mixing components at molecular level,...
AF coatings prevent the undesirable accumulation of a wide variety marine organisms (biofouling) on ship hulls can lead to significant increased costs, principally by fuel consumption.The bioactive compounds (biocides) used in antifouling coatings, like tributyltin (TBT), are banned for their toxic action towards non-target organisms.As consequence, development alternative with new natural products as biocides inhibit is key factor.In this approach, tara (Caesalpinia spinosa) tannin (TT)...
The undesirable accumulation of a wide variety marine organisms (biofouling) on ship hulls can lead to significantly increased costs, principally by fuel consumption maintain cruising speed. Generally, these coatings have bioactive compounds, called biocides. In this sense, paper deals with the assessment antifouling properties natural product derivative obtained from "quebracho" tannin and quaternary ammonium salt (hexadecyltrimethylammonium bromide ([CH3(CH2)15N(CH3)3]Br) . Two derivatives...
Filamentous fungi are microorganisms that cause deterioration of structural materials due to their ecological plasticity and vegetative functions. Functionalised sol-gel based products can be used control this kind biodeterioration through the association antifungal active additives which trapped in siloxane crosslinking. Bioactive microbial growth have been gaining more attention over years. However, concern about toxicity, bio-based approach has explored. The aim present research was...
In this work, the one-pot sol-gel synthesis of novel siliceous matrixes doped with carbon from spent batteries is reported. The obtained solids silver nitrate were characterized by their antifungal activity against Aspergillus sp., Cladosporium sp. and Chaetomium globosum, three well-known cellulolytic microorganisms responsible for deterioration cotton fabric. research it was possible to develop a methodology impregnation fabrics (brin type) evaluate efficacy. Cotton fabric containing...
