Graphenol defects induced blue emission enhancement in chemically reduced graphene quantum dots
In this work, few layers graphene quantum dots (GQDs) with size of 3–5 nm are purposely treated with highly concentrated aqueous NaBH4 solutions to obtain the reduced graphene quantum dots (rGQDs). Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy demonstrate that the numbers of carbonyl groups decrease but –OH related defects increa...

Peach gum for efficient removal of methylene blue and methyl violet dyes from aqueous solution
This study
investigated the potential use of natural peach gum (PG) as alternative
adsorbent for the removal of dyes from aqueous solutions.
The PG showed high adsorption capacities and selectivity for cationic dyes
(e.g., methylene blue (MB) and methyl violet (MV)) in the pH range 6-10. 98%
of MB and MV could be adsorbed within 5 min, and both of the adsorptions
reached equilibrium within 30...

200. Catalytic liquid marbles: Ag nanowire-based miniature reactors for highly efficient degradation of methylene blue.
Ag nanowire-based catalytic liquid marbles are fabricated as miniature reactors, which demonstrate highly efficient, support-free and rate-controllable heterogeneous degradation of methylene blue, with catalytic efficiency close to 100%. Our miniature catalytic liquid marbles are essential for reactions involving highly toxic/hazardous or costly reactants, where small volume preliminary reactions ...

Synthesis of new conjugated polyfluorene derivatives bearing triphenylamine moiety through a vinylene bridge and their stable blue electroluminescence
Two new conjugated polyfluorene derivatives bearing triphenylamine moiety through a vinylene bridge,PDPF and PBPF, have been successfully synthesized according to the Suzuki coupling method. The structures and properties of the monomers and the resulting conjugated polymers were characterized by using 1H NMR, 13C NMR, FT-IR, elemental analysis, GPC, TGA, DSC, UV-vis absorption spectrosco...

Acid blue AS doped polypyrrole (PPy/AS) nanomaterials with different morphologies as electrode materials for supercapacitors
Accepted Man
The polypyrrole (PPy) nanomaterials with different morphologies were prepared via
the chemical oxidative polymerization of pyrrole in the presence of acid blue AS (AS)
as the dopant and surfactant. Increasing of the feeding ratio of AS, the morphology of
the resultant acid blue AS doped polypyrrole (PPy/AS) nanomaterials changed from
nanoparticles to clusters of nanofibers and...
