Porous Silicon (PS) is fabricated by electrochemical etching of p-type Si. Graphene is deposited on the surface of Si and PS substrates by the Thermal Spray Pyrolysis (TSP) method. The current-voltage relationships of G/Si and G/PS devices are derived and studied under different volumes of ...
On the otherhand, the surface area of a few layers graphene, graphene oxide, and many other derivatives are much less in comparison to single-layer graphene [[1], [2], [3]]. Due to these exceptional properties, graphene acts as a perfect material for many modern technologies including ...
d, e A comparison of the EDS spectra of the contaminated area (d) and non-contaminated and monolayer area (e), which are marked as red and green boxes in b, respectively Full size image HAADF imaging of the parent graphite (98% purity) demonstrated a significant amount of silicon-based ...
In this work, expanded graphite was added into Cyrene and NMP (as comparison). Graphene flakes were produced during sonication treatment. Firstly, the sonication time for exfoliation was investigated as it is of significance for large-scale ink production. Samples were extracted at different sonicatio...
In this review, we outline the recent advancements in synthesizing of GQDs together with an analysis and comparison study on their pros and cons and suitable applications. Moreover, the applications of GQDs in drug delivery are summarized and discussed, while various GQDs based drug delivery-release...
The wafer scale graphene was produced using c-face silicon carbide (SiC) wafer and an array of graphene transistors were fabricated as shown in Fig. 1(d)[13]. The zoomed part of the individual transistor is shown below Fig. 1(d). The corresponding high-frequency measurement for the 240 ...
in comparison to the ZnO NPs PEGylated PpIX in which only 85% of cells are viable at a much lower concentration, 0.2 mM. In the presence of laser light (630 nm, 80 J/cm2), the cytotoxicity of ZnO NPs PEGylated PpIX was very evident and the complex induced cell damage. Besides, good...
recent progress on graphene-analogous low-dimensional materials (2D nanosheets and 1D nanoribbons) from both experimental and computational side, and emphasis is placed on structure, properties, preparation, and potential applications of graphene-analogous materials as well as the comparison with graphene....
In recent years, many chemical and physical methods have been proposed for the synthesis of graphene materials, including unzipping of CNTs, reduction of graphene oxide, microwave synthesis, epitaxial growth on single-crystal silicon carbide, chemical vapour deposition (CVD) on metal surfaces, liquid-...
Fig. 7(a–d) shows graphene inks printed on different substrates, including glass, Kapton, and silicon wafers. SEM images show that the printed graphene patterns represent wide graphene flakes with a lateral micro-level dimension (Fig. 7(e and f)). Download: Download high-res image (606KB...
