“…Additionally, the physicochemical properties of heavy metals like nickel (Ni) and cadmium (Cd) in smoke can vary depending on the form in which they are present. Elaborately, heavy metals would be present in smoke as both micro/nanoparticles and metal–organism composites in the corresponding solid particles of metal in a size range of micrometers to nanometers and metals bound to organic compounds or attached to biological material. − Additionally, with the high rejection rate of Ni (∼90%) and the low rejection rate of Cd (50%) by the membrane, there can be several potential mechanisms such as size exclusion, surface charge, chemical interactions, and adsorption capacity, but chemical interactions play a significant role in heavy metal filtration. Moreover, Figure d demonstrates a clear presence of the carbonyl functional group (CO) in the proposed MWCNT membrane, indicating its strong affinity to bind with nickel (Ni).…”

Rapid industrialization, haphazardous urbanization, and ruthless burning of fossil fuel have alarmingly impacted human health and the environment. The majority of health issues, such as asthma, cardiovascular disease, and cancer, are primarily associated with polyaromatic hydrocarbons (PAHs), particulate matter (PM), nickel (Ni) and cadmium (Cd) heavy metals, and other contaminants. To address these challenges, the development of an efficient air filtration unit to remove the toxic substances from the smoke is a necessity. The majority of the recently developed air filters are architecturally monotonous and bulky and suffer from a trade-off between removal effectiveness and air permeability. Herein, we have proposed an air filter which is scalable, ultralight (∼0.0034 g), thin (∼50 μm), thermally stable (∼500 °C), hydrophobic (contact angle 138° ± 6°), and porous (porosity of ∼57%) with a pore size of ∼16 nm and has an effective packing density of ∼0.64 g/cm3. The self-assembled nanoarchitecture network (nanonetwork) air filter has a relatively lower pressure drop (∼133.3 Pa) and can remove ∼99%, ∼99%, and ∼90% and 50% for PAHs, PM, and Ni and Cd heavy metals, respectively. This research will be highly beneficial for designing and developing high-performance fibrous materials for filtering and separation applications.

“…Stearic acid molecules form self‐assembled monolayers, triggered by their amphiphilicity, which can produce hydrophobic coatings on the top of hydrophilic surfaces [23, 24]. Stearic acid as a hydrophobic modifier has been widely used in superhydrophobic materials in recent years because of its low price, non‐toxic, harmless and excellent hydrophobic effect [25, 26]. Tapia et al [27] used stearic acid as hydrophobic agent to obtain hydrophobic polyurethane sponge, which can separate carbohydrates from water.…”

The synthesis of superhydrophobic materials by using inorganic materials and organic renewable materials is a hot topic in academic research. At present, the methods used to prepare superhydrophobic composites are complicated and the hydrophobic modifiers used are expensive. The authors report a simple and efficient method for the synthesis of superhydrophobic composites. At the beginning, the cellulose nanocrystal (CNC)/ZnO nanocomposites were prepared by mechanical blending method, and the surface micro-nano rough structure was constructed. Then the superhydrophobic CNC/ZnO nanocomposites were obtained by hydrophobic modification with cheap low surface energy substance. The results demonstrate that the inorganic-organic nanocomposites have excellent superhydrophobic properties, which indicates that the inorganic-organic nanocomposites have potential applications as hydrophobic additives in coatings and other fields.
