The discovery of graphene and graphene-like two-dimensional materials has brought fresh
vitality to the field of photocatalysis. Bandgap engineering has always been an effective way …

A facile method was developed to synthesize free-standing Si nanosheets by using
graphene oxide as a template. The resulting Si nanosheets were well-crystallized and …

Oxide-embedded and oxide-free alkyl-terminated silicon (Si) nanocrystals with diameters
ranging from 3 nm to greater than 10 nm were studied by Raman spectroscopy. For ligand …

The alloying reaction between 14th group elements and alkali can be detrimental for Li, Na
or K-ion batteries due to the large associated volume expansion that leads to a rapid …

Two-dimensional (2D) ultrathin silicon nanosheets (Si NSs) were synthesized by DC arc
discharge method and investigated as anode material for Li-ion batteries. The 2D ultrathin …

The improved phonon confinement model developed previously [11] is applied for definition
of germanium nanocrystal sizes from the analysis of its Raman scattering spectra. The …

We report the synthesis of silicon nanocrystalsvia a one-step route, namely, femtosecond
laser ablation in 1-hexene under ambient conditions. The size of these silicon nanocrystals …

The increased risk of chemical warfare agent usage around the world has intensified the
search for high-surface-area materials that can strongly adsorb and actively decompose …

The use of nonthermal plasmas for the processing of nanomaterials remains the focus of
ongoing investigations because of the many advantageous properties of this class of …

We develop a model for calculating the Raman scattering spectra from phonons confined in
for silicon nanocrystals, which is based on the familiar approach taking into account the …
