Exfoliated semiconducting MoS2 and WS2 were covalently functionalized with 1,2-dithiolane-modified carbon nanodots (CNDs). Based on electronic absorption and fluorescence emission spectroscopy, modulation of the optoelectronic properties of transition metal dichalcogenides (TMDs) by interfacing with CNDs was accomplished.

Ammonium modified MoS2 and WS2 were prepared and characterized by complementary spectroscopic, thermal and microscopic means. The positive charges on functionalized MoS2 and WS2, owed to the presence of ammonium units, were exploited to electrostatically bring in contact an anionic porphyrin bearing a carboxylate moiety, yielding porphyrin/MoS2 and porphyrin/WS2 nanoensembles, respectively.
Recent advances in large-scale production of graphene have led to the availability of solution-processable platelets at the commercial scale.
The game‐changing role of graphene oxide (GO) in tuning the excitonic behavior of conjugated polymer nanoparticles is described for the first time.
The preparation, characterization and photophysical and electrocatalytic properties of carbon nanodots (CNDs)/MoS2 ensembles were reported.
Carbon nanofoam (CNF) is a low-density, high-surface-area material formed by aggregation of amorphous carbon nanoparticles into porous nanostructures. We report the use of a pulsed infrared laser to prepare CNF from a graphene oxide (GO) target material.
Aqueous batteries are an emerging candidate for low‐cost and environmentally friendly grid storage systems. Designing such batteries from inexpensive, abundant, recyclable, and nontoxic organic active materials provides a logical step toward improving both the environmental and economic impact of these systems.
Our latest paper on functional #graphene emulsions published today in @nanoscale_rsc — The most sensitive liquid-based strain sensors ever reported!
This novel hybrid nanostructures opens new pathways for the design of improved optoelectronic devices.
N-methyl-2-pyrrolidone (NMP) has been shown to be the most effective solvent for liquid phase exfoliation and dispersion of a range of 2D materials including graphene, molybdenum disulphide (MoS2) and black phosphorus.
Electron Trap States and Photopotential of Nanocrystalline Titanium Dioxide Electrodes Filled with Single-Walled Carbon Nanotubes.
A new interdisciplinary study from groups at NHRF, IMN, INA, and Chimie des Interactions Plasma-Surface, University of Mons, Belgium, proves that 1,2-dithiolane derivatives can covalently anchored preferentially at the MoS2 sheet edges. This key result presents an important piece to the puzzle of 2D materials’ chemistry.
We report an improved method for the physical grafting of 1-nitropyrene (Pyr-NO2) onto highly graphitized carbon onion.
Using low-loss electron energy loss spectroscopy (EELS), in a scanning transmission electron microscope (STEM), it has been confirmed, following previous experimental (photoluminescence) and theoretical (DFT) studies, that the band gap of atomically thin nanoflakes of MoxW(1-x)S2 does shift with the alloying degree of the sample.
C60, the football shaped molecule whose discovery led to the Nobel Prize in 1996, has recently been proven to exist in space. A new study from EnEx groups at the IMN, NHRF and colleagues in seven other laboratories across Europe, Turkey and Canada suggests that ice layers can form spontaneously on the surface of crystals of C60 molecules, and that these water layers should be stable even under the extreme conditions of interstellar space.
