“…For example, PLLA/iron oxide nanocomposites have shown neurite extension in electrospun microfibers, Cai et al showed that PLLA/Fe 3 O 4 composites enhanced osteogenic differentiation [17] and in a similar way Dong et al showed enhanced osteogenic differentiation with PLLA/dicalcium silicate fibres. [18] In this context, ZnO NPs have attracted attention as antimicrobials [19,20] and UV blockers, [21] among others. Moreover, zinc is an essential element for cells, which acts as an intracellular secondary messenger in different cellular processes, [22,23] in particular, the lack of zinc can inhibit myoblast differentiation.…”

Graphical abstract2 Highlights  Biodegradable poly(L-lactide) matrix loaded with ZnO nanorods. Dynamic presentation of nanorods triggered by PLLA degradation. Changes in surface properties as a function of time control cell behaviour. Nanorods exposure promotes cell differentiation.3 Keywords: PLLA, ZnO nanoparticle, C2C12 myoblast, nanocomposite, cell differentiation AbstractThis work investigates the effect of the sequential availability of ZnO nanoparticles, (nanorods of ~ 20 nm) loaded within a degradable poly(lactic acid) (PLLA) matrix, in cell differentiation. The system constitutes a dynamic surface, in which nanoparticles are exposed as the polymer matrix degrades. ZnO nanoparticles were loaded into PLLA and the system was measured at different time points to characterise the time evolution of the physicochemical properties, including wettability and thermal properties. The micro and nanostructure were also investigated using AFM, SEM and TEM images. Cellular experiments with C2C12 myoblasts show that cell differentiation was significantly enhanced on ZnO nanoparticles -loaded PLLA, as the polymer degrades and the availability of nanoparticles become more apparent, whereas the release of zinc within the culture medium was negligible. Our results suggest PLLA/ZnO nanocomposites can be used as a dynamic system where nanoparticles are exposed during degradation, activating the material surface and driving cell differentiation.4

“…The low peak intensity at 2θ = 61.1 • correspond to the Cu 2 O (JCPDS 78-2076) which confirmed the oxidation of copper foil due to corrosion [21,22]. The XRD pattern of agar-Ferro/Ferricyanide electrolyte used as shown in Figure 5 indicated peaks at 2θ values of 26.6 • corresponding to Ferro/Ferricyanide [24] and peak at 17.0 • corresponds to agar film [25,26] which confirmed the presence of electrolyte without any degradation. Thus, the corrosion of copper foil was caused by graphene and water vapor rather than by the electrolyte.…”

Conversion of low-grade waste heat into electricity had been studied employing single thermocell or flowcells so far. Graphene coated copper electrodes based thermocells connected in series displayed relatively high efficiency of thermal energy harvesting. The maximum power output of 49.2 W/m 2 for normalized cross sectional electrode area is obtained at 60 • C of inter electrode temperature difference. The relative carnot efficiency of 20.2% is obtained from the device. The importance of reducing the mass transfer and ion transfer resistance to improve the efficiency of the device is demonstrated. Degradation studies confirmed mild oxidation of copper foil due to corrosion caused by the electrolyte.
