Nickel-Cadmium-Sulfide Anchored on rGO Nanocomposite for Removal of Textile Industry Dyes

The design and development of a novel route for the preparation of efficient photocatalysts for the treatment of polluted water is an essential need. Due to rapid expansion of pharmaceutical and textile industries, the discharge of drugs and sewage contaminants leads to water contamination. To address these issues, hydrothermally synthesized Ni–Cd–S/rGO nanocomposite with a cauliflower structure was developed. The prepared nanocomposite was studied using advanced characterization techniques to confirm crystal structure, surface morphology, optical studies and material composition in detail. Further, the photodegradation process of textile-based Methylene Blue (MB) and Methyl Orange (MO) dyes using Ni–Cd–S/rGO nanocomposite with desired time interval under natural sunlight was also investigated. The maximum photocatalytic performance of > 90% was achieved for the photocatalyst. The photodegradation rate can be maintained after 5 recycling tests in the presence of MB and MO dyes. The remarkable degradation efficiency, high rate constant and reusability of the Ni–Cd–S/rGO nanocomposite make it an excellent choice for textile effluent treatment

Efficacy of Graphene-Based Nanocomposite Gels as a Promising Wound Healing Biomaterial

The development of biocompatible nanocomposite hydrogels with effective wound healing/microbicidal properties is needed to bring out their distinguished characteristics in clinical applications. The positive interaction between graphene oxide/reduced graphene oxide (GO/rGO) and hydrogels and aloe vera gel represents a strong strategy for the advancement of therapeutic approaches for wound healing. In this study, the synthesis, characterization, and angiogenic properties of graphene-based nanocomposite gels have been corroborated and substantiated through several in vitro and in vivo assays. In this respect, graphene oxide was synthesized by incorporating a modified Hummer’s method and ascertained by Raman spectroscopy. The obtained GO and rGO were uniformly dispersed into the aloe vera gel and hydrogel, respectively, as wound healing materials. These formulations were characterized via in vitro bio-chemical techniques and were found suitable for the appropriate cell viability, attachment, and proliferation. In addition, in vivo experiments were conducted using male Wistar rats. This revealed that the GO/rGO-based gels stimulated wound contraction and re-epithelialization compared to that of the non-treatment group. From the study, it is suggested that GO/rGO-based aloe vera gel can be recommended as a promising candidate for wound healing applications
