Solar-to-chemical energy conversion via heterogeneous photocatalysis is one of the
sustainable approaches to tackle the growing environmental and energy challenges. Among …

A grand family of two-dimensional (2D) materials and their heterostructures have been
discovered through the extensive experimental and theoretical efforts of chemists, material …

In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the
subject of intense research efforts. Plasmon physics is intriguing and its precise modelling …

Conventional optical components such as lenses, waveplates and holograms rely on light
propagation over distances much larger than the wavelength to shape wavefronts. In this …

When metal nanoparticles are arranged in an ordered array, they may scatter light to
produce diffracted waves. If one of the diffracted waves then propagates in the plane of the …

Surface-enhanced Raman spectroscopy (SERS) and related spectroscopies are powered
primarily by the concentration of the electromagnetic (EM) fields associated with light in or …

For more than seven decades, hexagonal boron nitride (hBN) has been employed as an
inert, thermally stable engineering ceramic; since 2010, it has also been used as the optimal …

Surface-enhanced Raman scattering (SERS) has become a powerful tool in chemical,
material and life sciences, owing to its intrinsic features (ie, fingerprint recognition …
