“…Karthika Arumugam et al studied the degradation of the UPCs through vermicomposting, proving that earth worm and microbes (VCB) vermicomposting can short the UPCs degradation period and the degraded UPCs can be used as the fertilizer [ 2 ]. Zhao et al and Chen et al fabricated graphene sheets and carboxymethyl cellulose by using UPCs as raw materials [ 17 , 20 , 21 ]. Meanwhile, cellulose nanocrystals and cellulose nanofibers can also be obtained through a citric acid hydrolysis chemical method from the UPCs [ 18 ].…”

Paper cups are widely employed in daily life with many advantages, but most of the used paper cups are incinerated or landfilled, due to the great challenge of separating the thin inner polyethylene (PE) coating, causing the waste of energy and the pollution of our environment. Therefore, recycling and converting the used paper cups into high-value materials is meaningful and important. In this work, transparent cellulose-based films were successfully prepared from the used paper cups via 1-allyl-3-methylimidazolium chloride ionic liquid after simple pretreatment. Additionally, the difference in properties and structures of cellulose-based films regenerated in different coagulation baths (water or ethanol) was also explored. It was found that the cellulose-based film possessed good thermal property and displayed better hydrophobicity than the traditional pure cellulose film. Moreover, they also demonstrated good mechanical property and the tensile strength of cellulose-based film regenerated in water can reach 31.5 Mpa, higher than those of cellulose-based film regenerated in ethanol (25.5 Mpa) and non-degradable polyethylene film (9–12 MPa), indicating their great potential as the packaging materials. Consequently, valorization of the low cost used paper cups and preparation of high-valve cellulose-based films were realized simultaneously by a facile and green process.

“…It was first unambiguously produced and identified in 2004 [30,31]. Many efforts have been made to mass-produce graphene in selected industries, particularly materials science and chemistry [32]. According to recent price checks, allocated budgets for graphene fabrication and the production of its derivatives reached $67 million in 2015, and are estimated to increase to $680 million by 2020 [33].…”

Herein, we report recent developments in order to explore chitin and chitosan derivatives for energy-related applications. This review summarizes an introduction to common polysaccharides such as cellulose, chitin or chitosan, and their connection with carbon nanomaterials (CNMs), such as bio-nanocomposites. Furthermore, we present their structural analysis followed by the fabrication of graphene-based nanocomposites. In addition, we demonstrate the role of these chitin- and chitosan-derived nanocomposites for energetic applications, including biosensors, batteries, fuel cells, supercapacitors and solar cell systems. Finally, current limitations and future application perspectives are entailed as well. This study establishes the impact of chitin- and chitosan-generated nanomaterials for potential, unexplored industrial applications.

“…The exploitation of graphene-based nanomaterials has motivated a rapid development with respect to the reinforcement of the current technology of structured bio-nanomaterials in tissue engineering [9,10]. Graphene as a single-atom thick sheet of sp 2 hybridized carbon atoms is well-known for its remarkable properties, such as excellent mechanical strength, thermal and electrical conductivity, and high surface area [11,12]. Moreover, graphene oxide (GO) is obtained upon the oxidation of graphite through well-known oxidation processes, resulting in the attachment of oxygen functional groups onto the basal plane and the edges of the flakes [13].…”

Thanks to stem cells’ capability to differentiate into multiple cell types, damaged human tissues and organs can be rapidly well-repaired. Therefore, their applicability in the emerging field of regenerative medicine can be further expanded, serving as a promising multifunctional tool for tissue engineering, treatments for various diseases, and other biomedical applications as well. However, the differentiation and survival of the stem cells into specific lineages is crucial to be exclusively controlled. In this frame, growth factors and chemical agents are utilized to stimulate and adjust proliferation and differentiation of the stem cells, although challenges related with degradation, side effects, and high cost should be overcome. Owing to their unique physicochemical and biological properties, graphene-based nanomaterials have been widely used as scaffolds to manipulate stem cell growth and differentiation potential. Herein, we provide the most recent research progress in mesenchymal stem cells (MSCs) growth, differentiation and function utilizing graphene derivatives as extracellular scaffolds. The interaction of graphene derivatives in human and rat MSCs has been also evaluated. Graphene-based nanomaterials are biocompatible, exhibiting a great potential applicability in stem-cell-mediated regenerative medicine as they may promote the behaviour control of the stem cells. Finally, the challenges, prospects and future trends in the field are discussed.
