2-D materials have special lattice structures. Atoms in the same layer are usually bound by a covalent bond, while the force between layers is van der Waals coupling. They have super-clean surfaces ...

We report the controlled formation and characterization of heterojunctions between carbon nanotubes and different metal nanocrystals (Fe, Co, Ni, and FeCo). The heterojunctions are formed from ...

Photoelectrochemical catalysis is an attractive way to provide direct hydrogen production from solar energy. However, solar conversion efficiencies are hindered by the fact that light harvesting has ...

Electronically conducting two-dimensional (2D) materials are currently hot topics of research in both physics and chemistry due to their unique properties that have the potential to open new avenues ...

An international research team claims to have achieved optimal passivation in inverted perovskite solar cells by applying thin layers of low-dimensional perovskite on top of a 3D perovskite film. The ...

Three independent groups report the growth of two-dimensional heteromaterials with seamless vertical or lateral interfaces. The one-layer-thick transition metal dichalcogenides thus form ...

Mechanoluminescence (ML) is a type of luminescence that occurs when a material emits light in response to an external mechanical stimulus, such as scratching, pressing, or stretching. Unlike ...

2D organic-inorganic heterojunctions for applications in the field of multifunctional optoelectronic devices, including electronic devices, molecular switches, photodetectors, memory devices, ...

(Nanowerk Spotlight) The maxillofacial bone defects after the trauma, deformity, tumor, or infection may cause severe dysfunctions and dramatically decrease the life quality of patients. According to ...
