“…Remarkably, graphene is gradually becoming a promising biosensor material because of its extraordinary electrical conductivity at room temperature and its large specific surface area that is optically and chemically active. 10,11 Theoretically, graphene is a perfect atomic monolayer with infinite 2D expansion, and thus, it has been reported for wideranging applications. 12 Ding et al synthesized Cu 2 O/MoS 2 / reduced graphene oxide nanosheets with a larger specific surface area, higher response, and superior selectivity.…”

“…The fabrication of low‐cost filters from natural materials has the potential to provide cheaper cost‐effective water remediation solutions to rural communities leaving in the vicinity of polluted rivers and those dependent on groundwater for their daily needs. Other studies summarized the use of nanostructured materials such as spinel ferrite nanostructures [20] and materials such as exfoliated graphene [21] for the successful removal of various pollutants. The use of nanoparticles such as carbon nanoparticles have been utilized in the fabrication of filters for the removal of toxic metals [22] .…”

Producing drinking water from polluted water is expensive; thus, the fabrication of environmentally‐friendly and cost‐effective materials to treat polluted water is vital. A strategy involving the exploitation of waste resources to mitigate their impact on the environment has attracted special attention. This strategy is achievable by, among other things, developing materials including ceramic filters. In this study, natural clay, and macadamia nutshell powder were used to fabricate ceramic filters to remove methyl orange (MO), chromium (Cr), and lead (Pb) from aqueous solutions. The physicochemical characteristics of the fabricated filters were carried out and their ability to remove the pollutants was investigated. The filter with 20 wt% macadamia nutshell powder (M2) removed 92 %, 62 %, and 29 % of MO, Pb (II), and Cr (III), respectively. This was attributable to the high porosity of the filter as demonstrated by Brunauer‐Emmett‐Teller analysis. Furthermore, there was an increase on the removal of Cr (29.71 % to 84.5 %) in the presence of other competing co‐metals, however, a drop in Pb removed was observed (62.99 % to 38.67 %). Turbidity removal of up to 97.2 % was achieved using the M2 filter. The reported filter fabrication approach is facile, easy to replicate without special training, and environmentally friendly.

“…In the current research field of nacre-inspired composites, the preparation process of the bricks determines their morphology and structure. , The micrometers/nanosheets include clay, layered double hydroxides (LDH), graphite, and other artificial layers, which are difficult to prepare as large and uniform due to chemical or mechanical delamination leading to layer fracture and incomplete delamination. ,− In addition, sheet-like alumina and calcium carbonate nanoparticles synthesized by “down-top” methods cannot achieve high aspect ratios. , Therefore, adjustable uniform nanosheets with large diameters (≥10 μm) and high aspect ratios are urgently needed.…”

The nacre-inspired “brick-and-mortar” structure is used to prepare materials with high strength, toughness, and barrier performance by setting geometric parameters, such as the diameter, thickness, and aspect ratio of the assembly blocks. However, there have been no reports of large-diameter “bricks”. Herein, we report the synthesis of silica nanosheets with ∼20 μm diameter and adjustable aspect ratios using anionic and cationic surfactant micelle templates, and the self-assembly of the nanosheets was assisted by a heat pressing process to form ethyl cellulose (EC) composite films. Such a large-block brick-and-mortar structure has significantly improved the various properties of the composite films, including increasing the strength and Young’s modulus of the EC films by 160 and 429%, respectively, maintaining 97% transparency (with a content of 50 wt % silica nanosheets), and increasing gas barrier performance by 120 times. We establish comprehensive relationships among the high performance of nacre-inspired films and the diameter and aspect ratio of the nanosheets, which will pave the way for the practical application of flexible optical barrier films.
