DNA damage induced by multiwalled carbon nanotubes in mouse embryonic stem cells.
TLDR
The results suggest that careful scrutiny of the genotoxicity of nanomaterials is needed even for those materials, like multiwalled carbon nanotubes, that have been previously demonstrated to have limited or no toxicity at the cellular level.

BCN graphene as efficient metal-free electrocatalyst for the oxygen reduction reaction.
TLDR
This work has previously prepared vertically aligned nitrogendoped carbon nanotubes as ORR electrocatalysts, which are free from anode crossover and CO poisoning and show a threefold higher catalytic activity and better durability than the commercial Pt/C catalyst.

Polyaniline-grafted reduced graphene oxide for efficient electrochemical supercapacitors.
TLDR
Electron microscopic studies demonstrated that the resultant composite has fibrillar morphology with a room-temperature electrical conductivity as high as 8.66 S/cm and capacitance of 250 F/g with good cycling stability.

Polyelectrolyte-functionalized graphene as metal-free electrocatalysts for oxygen reduction.
TLDR
G graphene positively charged via intermolecular charge-transfer with PDDA was demonstrated to show remarkable electrocatalytic activity toward ORR with better fuel selectivity, tolerance to CO posing, and long-term stability than that of the commercially available Pt/C electrode.

Novel quinoxaline-based organic sensitizers for dye-sensitized solar cells.
TLDR
The relatively high power conversion efficiencies of 3.30 and 5.56% for RC-21 and RC-22, respectively indicates that the quinoxaline electron-accepting unit is quite a promising candidate in organic sensitizers.
