“…Nanomaterials have gained interest in different types of engineering applications (Mydin et al, 2023;Sathish et al, 2023;Suresh et al, 2023;Gul et al, 2023;Li et al, 2023). Due to their exceptional properties, carbon nanotubes (CNTs) have recently found extensive use in polymer-based nanocomposites (Said et al, 2023a;Prasanthi et al, 2023;Gul et al, 2023;Devi et al, 2023;Said et al, 2023b). Experimental studies have shown that CNTs possess superior mechanical characteristics in comparison to continuous carbon fibers (Sun et al, 2005;Jia et al, 2011;Ahmad et al, 2022c).…”

A novel generation of composite sandwich beams with laminated carbon fiber-reinforced polymer skins and pultruded glass fiber-reinforced polymer core materials was examined for their flexural behavior. The strength and failure mechanisms of the composite sandwich beams in flatwise and edgewise configurations were investigated using three-point static bending tests. These sophisticated composite structures must be designed and used in a variety of sectors, and our research provides vital insights into their performance and failure patterns. In comparison to the reference specimens (FGM-1), the carbon nanotube-reinforced specimens’ bending capacity was affected and ranged from −2.5% to 7.75%. The amount of the carbon nanotube addition had a substantial impact on the beams’ application level and load-carrying capacity. Particularly, the application of 0.5 wt% additive in the outermost fiber region of the beams, such as in FGM-4, led to an increase in the bending capacity. However, the stiffness values at the maximum load were decreased by 0.3%–18.6% compared to FGM-1, with the minimum level of the decrease in FGM-4. The experimental results were compared with the theoretical calculations based on the high-order shear deformation theory, which yielded an approximation between 11.99% and 12.98% by applying the Navier’s solution.

“…Excess or deficiency of Fe 3+ in the body can result in serious diseases, such as hereditary hemochromatosis and endotoxemia [ 23 ]. Inorganic oxo-anions, especially Cr 2 O 7 2− and MnO 4 − , have been considered as highly toxic pollutants originating from industrial wastewater, and may cause skin allergies or even induce cancers [ 24 ]. Therefore, it is imperative to exploit fluorescent CPs to efficiently detect these hazardous species in aqueous media.…”

A novel coordination polymer [Zn(atyha)2]n (1) (Hatyha = 2-(2-aminothiazole-4-yl)-2- hydroxyiminoacetic acid) was constructed by hydrothermal reaction of Zn2+ with Hatyha ligand. CP 1 exhibits a 2D (4,4)-connected topological framework with Schläfli symbol of {44·62}, where atyha− anions serve as tridentate ligands, bridging with Zn2+ through carboxylate, thiazole and oxime groups. CP 1 displays a strong ligand-based photoluminescence at 390 nm in the solid state, and remains significantly structurally stable in water. Interestingly, it can be utilized as a fluorescent probe for selective and sensitive sensing of Fe3+, Cr2O72− and MnO4− through the fluorescent turn-off effect with limit of detection (LOD) of 3.66 × 10−6, 2.38 × 10−5 and 2.94 × 10−6 M, respectively. Moreover, the efficient recyclability for detection of Fe3+ and Cr2O72− is better than that for MnO4−. The mechanisms of fluorescent quenching involve reversible overlap of UV-Vis absorption bands of the analytes (Fe3+, Cr2O72− and MnO4−) with fluorescence excitation and emission bands for CP 1, respectively.

“…Nanomaterials (NMs) with a series of superior performances have been widely used in medicine, mechanics, electronics, agriculture and the energy field [ 1 , 2 , 3 , 4 ]. As one of the most attractive NMs with multiple forms, carbon-based nanomaterials (CBNs) with nano-sized and unique physico-chemical properties, including graphene oxide (GO), single-walled carbon nanotubes, multiple-walled carbon nanotubes, carbon nanoparticles and fullerenes, provoke tremendous scientific interest for nanotechnology development of a wide range of medical and industrial applications [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Among them, GO, as a novel CBN, presents the widest application duo to more fascinating properties, such as high surface area, good thermal stability, excellent mechanical strength, high optical transmittance and electrical conductivity [ 15 , 16 , 17 , 18 ].…”

“…Phytoremediation is an emerging technology of contamination control, which takes advantage of a hyperaccumulator to clean up hazardous heavy metals in environment [ 59 , 60 , 61 ]. Meanwhile, GO is considered as an efficient adsorbent CBNs applied to remove heavy metals from aquatic environment or wastewater due to its excellent physicochemical properties, such as strong hydrophilia, abundant oxygen functional groups, and large specific surface area [ 9 , 11 , 12 , 20 , 30 , 62 , 63 , 64 , 65 ]. It is obvious to show that greening hyperaccumulator and GO are both beneficial for removing heavy metals in contaminated urban environment; however, little information is available on the effects of GO on a greening hyperaccumulator under heavy-metal Cd stress.…”

Graphene oxide (GO), as a novel carbon-based nanomaterial (CBN), has been widely applied to every respect of social life due to its unique composite properties. The widespread use of GO inevitably promotes its interaction with heavy metal cadmium (Cd), and influences its functional behavior. However, little information is available on the effects of GO on greening hyperaccumulators under co-occurring Cd. In this study, we chose a typical greening hyperaccumulator (Lonicera japonica Thunb.) to show the effect of GO on Cd accumulation, growth, net photosynthesis rate (Pn), carbon sequestration and oxygen release functions of the plant under Cd stress. The different GO-Cd treatments were set up by (0, 10, 50 and 100 mg L−1) GO and (0, 5 and 25 mg L−1) Cd in solution culture. The maximum rate of Cd accumulation in the roots and shoots of the plant were increased by 10 mg L−1 GO (exposed to 5 mg L−1 Cd), indicating that low-concentration GO (10 mg L−1) combined with low-concentration Cd (5 mg L−1) might stimulate the absorption of Cd by L. japonica. Under GO treatments without Cd, the dry weight of root and shoot biomass, Pn value, carbon sequestration per unit leaf area and oxygen release per unit leaf area all increased in various degrees, especially under 10 mg L−1 GO, were 20.67%, 12.04%, 35% and 28.73% higher than the control. Under GO-Cd treatments, it is observed that the cooperation of low-concentration GO (10 mg L−1) and low-concentration Cd (5 mg L−1) could significantly stimulate Cd accumulation, growth, photosynthesis, carbon sequestration and oxygen release functions of the plant. These results indicated that suitable concentrations of GO could significantly alleviate the effects of Cd on L. japonica, which is helpful for expanding the phytoremediation application of greening hyperaccumulators faced with coexistence with environment of nanomaterials and heavy metals.
