“…Also, the inclusion of ZnO in PLA matrix causes severe degradation of the PLA matrix during processing 74 . Meanwhile, AgNP has the additional benefit of being synthesized by green methods without involving chemical reagents, 75,76 and its antimicrobial activities 37,77‐79 is being extended to COVID‐19 80 . Thus, we restrict the review, principally, to CNT, MMT, AgNP and their hybrids with other promising fillers.…”

The global concern over the environmental protection and bio‐sustainability of plastic waste materials has prompted a vibrant search for renewable and biodegradable polymers in the academia and industrial sectors. Amidst other biopolymers, poly(lactic acid) (PLA) is identified as the most promising thermoplastic aliphatic polyester. PLA is derived from agricultural products with unique physical and mechanical properties that are comparable with the conventional petroleum‐derived polymers. Yet, some of the properties are insufficient for advanced materials applications. Rigid nanoparticles are incorporated in the PLA matrix to alleviate its properties for specific high‐performance applications. Here, we report various approaches of preparing functional PLA nanocomposites with emphasis on the strengths and weaknesses of each of the methods, as well as the achieved properties enhancement for a targeted application. Designing high‐performance PLA nanocomposite involves careful selection of the most appropriate nanofillers or combinations of nanofillers, preparation technique and processing parameters. Besides multi‐walled carbon nanotubes (CNT) and montmorillonite (MMT) that are prominent as nucleating agents to achieve high thermal and mechanical properties, other nanofillers like silver nanoparticles (AgNP) play critical roles in improving antibacterial and high‐performance properties of PLA.

“…After the addition of AS or AS-CS, the zeta potentials increased to −2.65 ± 0.07 mV. Different from the GDM control system, the zeta potentials of AS and AS-CS decreased after passing through the UF membrane, which can be explained by the enrichment of microorganisms with negative charges (Figure S6a) [35]. Figure S6b shows that the pH values in all steps are in the range of 6.7-7.2, which is suitable for the growth of microorganisms [36].…”

Gravity-driven membrane (GDM) ultrafiltration is a promising water treatment method due to its low energy consumption and low maintenance. However, the low stable permeability in algae-laden water treatment is currently limiting its wider application. With the ultimate goal of increasing permeability, the aim of this study was to evaluate the effect of a composite coagulant of aluminum sulfate-chitosan (AS-CS) on the GDM filtration performance. In parallel tests with a single AS coagulant and without pre-coagulation, the analysis of membrane fouling resistance and the membrane fouling mechanism were evaluated. The results indicated that the AS-CS/GDM system can alleviate 23.74% and 58.80% membrane fouling, respectively, compared with AS/GDM and the GDM system. The AS-CS/GDM system can effectively remove humic-like substances having a molecular weight (MW) of 3–100 kDa, resulting in removal of 98.32% of algae cells and removal of 66.25% of dissolved organic carbon; the AS-CS/GDM system thereby improved the concentration of attached biomass on the membrane surface with the stronger biodegradability of organic matters. The application of AS-CS pre-coagulation in the GDM process could enhance the proliferation of microorganisms and the removal of low molecular weight humic-like substances. Therefore, the AS-CS/GDM system is a potentially important approach for algae-laden water treatment.

“…In the first step of testing metal nanoparticles as potential animal feed additives, many researchers conduct preliminary nano-toxicological studies to determine the impact of examined nanoparticles on cell cultures (Leng et al 2020 ) or animal models, for example mice (Zhang et al 2008 ; Kesmati et al 2016 ), rats (Tomaszewska et al 2017 ; Mazaheri et al 2019 ; Sanati et al 2019 ; Kociova et al 2019 ; Bidian et al 2021 ; Naz et al 2021 ), worms (Ayech et al 2020 ), insects like Drosophila melanogaster (Pilaquinga et al 2021 ) or in the case of aquatic organisms on water flea, like Daphnia magna (Gong et al 2016 ; Conine and Frost 2017 ), Ceriodaphnia dubia (Li et al 2011 ) or fish (Gutierrez et al 2021 ). The findings obtained for these organisms may be extrapolated on other living beings (Pilaquinga et al 2021 ).…”

The application of high doses of mineral feed additives in the form of inorganic salts increases the growth performance of animals, but at the same, due to their low bioavailability, can contaminate the environment. Therefore, there is a need to find a replacement of administering high doses of minerals with an equally effective alternative. The application of lower doses of metal-containing nanoparticles with the same effect on animal production could be a potential solution. In the present review, zinc, silver, copper, gold, selenium, and calcium nanoparticles are discussed as potential feed additives for animals. Production of nanoparticles under laboratory conditions using traditional chemical and physical methods as well as green and sustainable methods – biosynthesis has been described. Special attention has been paid to the biological properties of nanoparticles, as well as their effect on animal health and performance. Nano-minerals supplemented to animal feed (poultry, pigs, ruminants, rabbits) acting as growth-promoting, immune-stimulating and antimicrobial agents have been highlighted. Metal nanoparticles are known to exert a positive effect on animal performance, productivity, carcass traits through blood homeostasis maintenance, intestinal microflora, oxidative damage prevention, enhancement of immune responses, etc. Metal-containing nanoparticles can also be a solution for nutrient deficiencies in animals (higher bioavailability and absorption) and can enrich animal products with microelements like meat, milk, or eggs. Metal-containing nanoparticles are proposed to partially replace inorganic salts as feed additives. However, issues related to their potential toxicity and safety to livestock animals, poultry, humans, and the environment should be carefully investigated.
