Metamaterials, as artificially structured materials composed of subwavelength arrays of
resonant unit cells, can exhibit exotic properties beyond those accessible to natural …

In this article we review Raman studies of defects and dopants in graphene as well as the
importance of both for device applications. First a brief overview of Raman spectroscopy of …

Nitrogen dioxide (NO2) is a gas species that plays an important role in certain industrial,
farming, and healthcare sectors. However, there are still significant challenges for NO2 …

sp 2 hybridized carbons constitute a broad class of solid phases composed primarily of
elemental carbon and can be either synthetic or naturally occurring. Some examples are …

Fenton reaction has important implications in biology-and environment-related remediation.
Hydroxyl radicals (• OH) and hydroxide (OH–) were formed by a reaction between Fe (II) and …

Herein, a nanoconfinement strategy was employed to encapsulate nano zero-valent iron
(confined-Fe 0) for the rapid degradation of sulfamethoxazole (SMX) through a …

We investigate the evolution of the Raman spectrum of defected graphene as a function of
doping. Polymer electrolyte gating allows us to move the Fermi level up to 0.7 eV, as directly …

Light-weight and flexible microwave absorbers are in increasing demand because of the
electromagnetic (EM) pollution. Carbon fiber mats are promising as they have high flexibility …

Efficient and stable photoelectrochemical reduction of CO2 into highly reduced liquid fuels
remains a formidable challenge, which requires an innovative semiconductor/catalyst …

Two-dimensional piezotronics will benefit from the emergence of new crystals featuring high
piezoelectric coefficients. Gallium phosphate (GaPO4) is an archetypal piezoelectric …
