The π−π interaction has always been applied to explain the binding mechanism of OFL with C = C double bonds adsorbed on the surface of graphene. On the other hand, graphene also contains π electrons and may interact with the π electrons of benzene rings of OFL by means of π−π electron coupling ( Chen et al. 2015 ).

2020/8/15In this study, a novel sensor for highly selective and rapid detection of ciprofloxacin is fabricated. A facile strategy was employed to fabricate the electrode by electro-polymerization of phenol red (PPR) followed by drop-casting of reduced graphene oxide (rGO).

Destruction of amyloid fibrils by graphene through

2015/11/28Cell viability and ROS assays indicate that graphene oxide can indeed mitigate cytotoxicity of Aβ peptide amyloids. Our findings provide new insights into the underlying molecular mechanisms that define graphene-amyloid interaction and suggest that further research on nanotherapies for Alzheimer's and other protein aggregation-related diseases is warranted.

Enabling Graphene Oxide Nanosheets as Water

2013/3/14We report a novel procedure to synthesize a new type of water separation membrane using graphene oxide (GO) nanosheets such that water can flow through the nanochannels between GO layers while unwanted solutes are rejected by size exclusion and charge

Atomic

2021/4/29Gated ion flow in graphene oxide membranes Cells are adept at fast, gated ion flow through tailored channels, which is key to many biological processes. Xue et al. developed ion transistors from reduced graphene oxide membranes and observed a field-enhanced diffusivity of the ions (see the Perspective by Hinds).

Adsorption and removal of tetracycline antibiotics from

Graphene oxide (GO) is a potential effective absorbent for tetracycline antibiotics and can be used to remove them from aqueous solution. Tetracycline strongly deposited on the GO surface via π-π interaction and cation-π bonding.

A study on the corrosion and electrochemical properties of

The corrosion properties and passive film behaviour of wrought (WR) and electron beam melted (EBM) Ti-6Al-4V (Titanium Grade 5 or TG5) were compared in simulated physiological solution. Microstructural characterization was performed using field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) to correlate the microstructural characteristics to corrosion resistance

Rational synthesis of atomically precise graphene

These thermally triggered processes led to formation of finite-length seven-armchair graphene nanoribbons (7a-GNRs) terminated by well-defined zigzag ends (). Such finite 7a-GNRs are open-shell character molecules with a single electron localized at each end ( 7, 32 ).

Graphene synthesis graphene/polymer nanocomposites

Physical blending processes cannot provide enough interaction at the interfaces, whereas chemical blending processes can yield strong interaction such as covalent bonds. Aqueous blending of graphene or graphene oxide nanocomposites with water soluble matrix polymers also cause Tg increases, even though the blending processes involve no chemical reactions.

Next, the liquid is filtered out, leaving flakes of graphene oxide to clog up the filter. The sum of all the clogs across the filter eventually makes up a paperlike sheet of graphene oxide. This paperlike sheet can then be removed from the filter by dissolving the filter away using a solvent that doesn't react with graphene oxide.
