“…Bionanocomposites are an emerging class of nanostructured hybrid biomaterials, involving a bioderived polymer combined with organic or inorganic fillers, showing at least one dimension at the nanometric scale [1][2][3]. These promising materials have potential industrial applications as an alternative to nanocomposites based on fossil-fuel derived thermoplastics, in attempting to solve the environmental concerns related to the intensive utilization of nonrenewable resources [4,5]. Similarly to the nanocomposites based on traditional polymers, the introduction of very low nanofiller loadings allows for enhancing some inherent properties of biopolymers, such as brittleness, low melt viscosity and low heat distortion temperature, which remarkably limit the utilization of these materials for a wide range of industrial applications [6][7][8].…”

In this work, bionanocomposites based on different biodegradable polymers and two types of nanofillers, namely a nanosized calcium carbonate and an organomodified nanoclay, were produced through melt extrusion, with the aim to evaluate the possible applications of these materials as a potential alternative to traditional fossil fuel-derived polyolefins, for the production of irrigation pipes. The rheological behavior of the formulated systems was thoroughly evaluated by exploiting different flow regimes, and the obtained results indicated a remarkable effect of the introduced nanofillers on the low-frequency rheological response, especially in nanoclay-based bionanocomposites. Conversely, the shear viscosity at a high shear rate was almost unaffected by the presence of both types of nanofillers, as well as the rheological response under nonisothermal elongational flow. In addition, the analysis of the mechanical properties of the formulated materials indicated that the embedded nanofillers increased the elastic modulus when compared to the unfilled counterparts, notwithstanding a slight decrease of the material ductility. Finally, the processing behavior of unfilled biopolymers and bionanocomposites was evaluated, allowing for selecting the most suitable material and thus fulfilling the processability requirements for pipe extrusion applications.

“…Several approaches are employed for the treatment of heavy metal pollution in wastewater, including chemical precipitation ( Sarker et al, 2018 ), ion exchanges ( Hashim et al, 2011 ), membrane separation ( Chen et al, 2021a ), evaporation ( Chen et al, 2010 ), electro-coagulation ( Bouhamed et al, 2012 ), and sorption ( Al-Shannag et al, 2015 ; Chen et al, 2021b ; Dong et al, 2021 ). Among these, the adsorption technique is widely recognized as the optimal choice for removing contaminants from water ( Dinari and Tabatabaeian, 2018 ; Duman et al, 2020 ; Hoslett et al, 2020 ; Tabatabaeian et al, 2021 ). This technique is valued for its simplicity ( Wu et al, 2018 ), efficiency ( Liu et al, 2019 ), environmental friendliness ( Chen et al, 2018 ), excellent removal efficacy ( Zhang et al, 2017 ), and affordability ( Wang et al, 2020 ).…”

The innovative adsorbents known as the Metal-organic Framework (MOFs) had a high specific surface area, various structural types, and good chemical stability. MOFs have been produced through hydrothermal, mechanochemical, microwave-assisted, gelation, and other synthesis methods, and the solvothermal process is one of them that researchers frequently utilize. The UiO materials have a more comprehensive application potential than different subtypes of MOFs among the numerous MOFs that have been synthesized. The synthesis of MOFs and their composites, as well as the adsorption characteristics of UiO materials in the adsorption of various heavy metal ions, have all been examined and summarized in this study.

“…Layered double hydroxides (LDHs) have gained considerable attention because of their wide applications in various fields such as adsorption, catalysis, medicines, and sensors. − LDHs are represented by the formula [M (1– x ) 2+ M x 3+ (OH) 2 ] x + [A n – x / n ] x + · m H 2 O in which M 2+ and M 3+ are metal ions and A n – is the intercalated anion of valency n . x is typically in the range of 0.17 to 0.33.…”
