FESEM images (Figure 2) shows electrospun PCL scaffolds with smooth fibre structures while that of painted scaffolds were decorated with the GO, GP and CQ that were rough in nature.
The scaffolds must be mechanically stable so that they retain its structure after in vivo implantation in load-bearing tissues such as bones [45,46].

These materials include graphene supported inorganic nanomaterials and films, graphene-metal decorated nanostructures, Core/shell structures of nanocarbon-graphene and graphene doped polymer hybrid nanocomposites etc.
Recently, various metals, metal oxides and semiconducting NPs have been incorporated to graphene two-dimensional (2D) structures aiming to develop bulk graphene-NP hybrid nanocomposites which include GO/RGO hybrid 2D structures [4,11,16,24,26].
In order to extend the advantage of CNT spacers, a 3D CNT/graphene sandwiched (CGS) structure with CNT pillars grown between the graphene layers was developed via a CVD process [11].
These metal oxide NPs are grown on GO using solution chemistry followed by hydrothermal, thermal or chemical reduction to intimate contact between RGO and NPs.
A novel graphene/CdS-QD bilayer structure can work as the electron transfer system in photovoltaic devices [11].

is flattened and the material strain-hardens with
the formation of a typical dislocation and/or

The main disadvantage of such structures is the high cost [32].
In Fig. 15, we see the smaller structures, e.g., ‘buoys’ and linear longer structures or ‘linear absorbers’ with fitted hydraulic Ram joints and all the structures are fixed at the base of the sea or sea bed with fixed heavy weights to prevent it from being floated away.
It is different from the structure of a conventional dam.
The barrage structure is fitted with sluice gates and turbines [44-45].

However, protein chemistry has its own issues – expression system for the desired protein, efficient purification of the target protein, proper folding of the purified protein, stability of the functional protein, mode of application of experimental protein etc.
Many kinds of amino acid sequences have been applied in protein chemistry as tag for facilitated expression and purification of target protein including, FLAG, HA, cMyc, multi-His etc [18].
It has been shown that hepatocytes could maintain their differentiated phenotypes by forming 3D spheroid structure, or multi-layer cell aggregates, which require E-cad-mediated cell-cell interaction [50].

Abstract.
Metal-based nanoparticles, such as silver, titanium oxide, and zinc oxide, can be utilized as antivirals, as they can release metal ions that damage microorganisms by disrupting essential structures or biochemical pathways [14].
Furthermore, chitosan possesses amine groups in its skeletal structure, which can be used to couple with other compounds [27].
