“…34 In addition, the peak at 1402 cm −1 was assigned to C-OH; the stretching peak of alkoxy (C-O-C) was observed at 1062 cm −1 and the peak around 1216 cm −1 was associated to the vibration of epoxide bond (-O-). 50 In the case of GCNC, the peak at 1062 cm −1 disappeared, the intensities of the other peaks were lowered which confirm the partial reduction of GO during the formation of GCNC. In addition, the peak at 1062 cm −1 , which corresponds to the vibration of C-OH, disappeared from the GCNC spectrum, while a new intense peak is observed at 622 cm −1 which belongs to the Cu-O bond, 51,52 this is because of the chemical bond between CuO NPs and GO.…”

“…The FTIR spectrum (Figure 2) demonstrates the presence of the characteristic peaks of GO at 1636 and 3418 cm −1 which correspond to the stretching vibrations of C=C and O–H bands, respectively 34 . In addition, the peak at 1402 cm −1 was assigned to C–OH; the stretching peak of alkoxy (C–O–C) was observed at 1062 cm −1 and the peak around 1216 cm −1 was associated to the vibration of epoxide bond (–O–) 50 . In the case of GCNC, the peak at 1062 cm −1 disappeared, the intensities of the other peaks were lowered which confirm the partial reduction of GO during the formation of GCNC.…”

The purpose of this paper is the investigation of the catalytic effect of graphene oxide–copper oxide nanocomposite (GCNC) on the thermal comportment and decomposition reaction kinetics of a double‐base propellant (DBP) formulation. Differential scanning calorimetry (DSC) was used to conduct the thermal analysis. Using well‐known iso‐conversional kinetics methods, namely, Vyazovkin's nonlinear integral with compensatory effect (VYA/CE), Kissinger–Akahira–Sunose (KAS), and Flynn–Wall–Ozawa (FWO), the thermokinetic parameters for the investigated propellant, including activation energy and frequency factor, were estimated. Additionally, based on the results obtained from the kinetic analysis, the critical ignition temperature was calculated. The results showed that after the addition of GCNC, the activation energy barrier is lowered by 18%, and the critical ignition temperature is reduced.

“…Another group made silica from rice husk and coupled it with GO in situ using (3-aminopropyl) triethoxysilane as a coupling agent. The obtained NC had an enhanced surface area and was used to remove Pb 2+ from an aqueous solution (Thy et al, 2021). The hydroxyapatite nanoadsorbent prepared by microwave irradiation of egg shells also had high adsorption capacity for Pb 2+ from wastewater samples (Safatian et al, 2019).…”

Wastewater remediation is of paramount importance for the water-stressed modern civilization from the perspective of sustainable development and the management of limited freshwater resources. Contaminants such as heavy metal and metalloid ions, toxic dyes, and pathogenic microbes present in the aquatic ecosystem have adverse effects not only on the environment but also on human health. Traditional wastewater remediation processes are costly, energy-consuming, and have less efficiency in removing pollutants from wastewater. Multi-phasic nanomaterials or nanocomposites have enormous potential for removing contaminants from water bodies. These materials have an enormous tunable surface area for interacting with the target toxicants and are extremely stable in the aquatic system, but they readily agglomerate. Many research groups have exploited biosorption, bioleaching, and bioprecipitation capacities of fungal hyphae for wastewater remediation. Recently, researchers have attempted to explore the synergistic effect of the bionanocomposite of fungal hyphae and nanomaterials for removing pollutants from wastewater. This bionanocomposite has already shown promise as a superior material for wastewater treatment and can easily be separated from the polluted water for reuse over several cycles. The bionanocomposite-mediated decontamination of water can lead to a total paradigm shift in wastewater management strategies.
