Controlling materials properties through atomic
structure tuning is one of the most attractive
challenges in materials science. This functional
tunability can be achieved in the materials by a
modification of the underlying surface and interface
chemistry. Surfaces and interfaces are highly
influential because of their effect on synthesis-property
correlations in nanomaterials, thin films, and
coatings. In other words, the interfaces play an
important part in guiding the atomic ordering and
determining the functional properties in materials.
To develop a fundamental understanding of the
underlying mechanisms, advanced characterization
methods need to be adopted, which are the focus of
this themed topic.
This topic covers the studies on the advanced
characterization of materials interfaces at multiple
length scales in metal, alloys, ceramics, and
twodimensional materials using various experimental
as well as theoretical techniques. It also emphasizes
the role of interfaces on manipulation of synthesis
parameters to attain different morphologies of
nanostructured materials. The studies included in
the current issue involve the experimental results
obtained by nanomechanical Raman spectroscopy,
x-ray diffraction (XRD), scanning electron
microscopy (SEM), transmission electron microscopy
(TEM), atomic force microscopy (AFM), and
photoluminescence, etc. On the other hand, it also
includes research work focused on molecular
dynamics simulations as phenomenologic modeling
approaches.
In this editorial, we highlight experimental and
theoretical advancements in various research works
published in this issue. In the research works by S.
Gupta et al. and A. Bhaumik et al., we discuss the

synthesis and characterization of the recently
discovered quenched Q-carbon phase and direct
conversion of amorphous carbon to single crystalline
diamond. The work also emphasizes the critical role
of the substrate and sp3/sp2 composition in the
amorphous film on the morphologic changes
occurring in pulsed laser annealing-induced Q-carbon
and nanodiamonds. Y. Zhang et al. report insights
into the in situ measurement of stress distribution
during elevated temperature deformations in In-617
using nanomechanical Raman spectroscopy. The
research team of A. Pandey utilized Raman and
UV–Vis spectroscopy techniques to understand the
absorbent nature of 3D graphene oxide for
methylene blue. In another work, H. Kim et al. present the
mechanism of interface cracking and its effect on
the electrical performance of solar cells. On the
simulation front, S. Song et al. demonstrate the
molecular dynamics studies on the swelling nature
of Montmorillonite under interlayer cation
hydration. Overall, this topic of Advanced
Characterization of Interfaces and Thin Films discusses the
research works implementing a broad spectrum of
advanced characterization methods with emphasis
on interface chemistry and its relation to material
performance.

topic ‘‘Advanced Characterization of Interfaces and
Thin Films’’ in the April 2018 issue (vol. 70, no. 4) of
