Conventional preparation methods of carbon dots (CDs), generally causing low atom utilization and environmental unfriendliness due to the use of massive solvents, make it difficult for CDs to be synthesized on a large scale. In this work, a one-step solid-phase pyrolysis method was used to address the problems mentioned above. Selecting citric acid...

Graphitic carbon nitride (g-C3N4), as a novel carbon material, has gained widespread attention during the last years. Although the g-C3N4 can be synthesized by utilizing various N-rich precursors, the photocatalytic performance of the derived g-C3N4 significantly alters depending on the type of used precursor. In our study, we choose economical ure...

We present and discuss the role of nanoparticles size and stoichiometry over the local atomic environment of nanostructured VOx films. The samples have been characterized in situ using X-ray absorption near-edge structure (XANES) spectroscopy identifying the stoichiometry-dependent fingerprints of disordered atomic arrangement. In vanadium oxides, ...

A non-energy intense route was used for the synthesis of highly crystalline WO3 nanocubes. The morphological studies confirmed the cuboidal shape of the nanocrystals. Raman spectrum result for the synthesized sample revealed that the vibrational modes correspond to those ones assigned to single phase stoichiometric WO3. The band gap Eg was derived ...

Discovery of new photocatalytic materials that can efficiently degrade organic contaminants is of great interest. In the present work, TiO2 was spatially dispersed over two siliceous mesoporous supports, SBA-15, representing an example of a material with periodic and ordered array of pores and SiO2-aerogel-10, as an example of an aperiodic material...

As a substitute for pure silver nanoparticles, Cu-Ag core-shell nanoparticles (CS NPs) have received significant attention in the fields of electronic packaging and conductive inks. Shell thickness is one of the important factors affecting the sintering performance of CS NPs. In this work, we conduct a multi-particle molecular dynamics simulation t...

Splitting of D band is observed in vertically aligned graphene nanowalls (VAGNWs) during analysis of Raman spectroscopy for the first time and two distinct peaks were observed, designated as D1 and D2. Evolution of D band with increasing laser power is studied and it is seen that intensity and full width at half maxima (FWHM) of D2 get reduced with...

Nanoindentation is a powerful tool capable of providing fundamental insights of material elastic and plastic response at the nanoscale. Alloys at nanoscale are particularly interesting as the local heterogeneity and deformation mechanism revealed by atomistic study offers a better way to understand hardening mechanism to build a stronger material. ...

Hierarchical CdS nanocrystals were synthesized with chitosan as the additive by solvothermal method. The concentration of chitosan had obvious influence on the morphology of CdS. When 2.5 mg/mL chitosan was added into the system, spherical CdS with the size of 200–300 nm assembled by hexagonal microspheres was formed. CdS was characterized by X-ray...
