It is estimated that the world will need to double its energy supply by 2050. Nanotechnology has opened up new frontiers in materials science and engineering to meet this challenge by creating new materials, particularly carbon nanomaterials, for efficient energy conversion and storage. Comparing to conventional energy materials, carbon nanomaterials possess unique size-/surface-dependent (e.g....

We report the fabrication of a hybrid light-harvesting electrode consisting of photosystem I (PSI) proteins extracted from spinach and adsorbed as a monolayer onto electrically contacted, large-area graphene. The transparency of graphene supports the choice of an opaque mediator at elevated concentrations. For example, we report a photocurrent of 550 nA/cm(2) from a monolayer of PSI on graphene...

Graphene is considered to be the ‘wonder material’ because of many unique and fascinating properties, such as high mechanical strength (200 times stronger than steel. Young’s modulus ~ 1100 Gpa), exceptionally thin nanostructure (1 million times thinner than human hair and world’s first twodimensional material made up of single layer of hexagonally arranged sp2-bonded carbon atoms, cf. (Figure ...

Since the first report of graphene, thin two-dimensional (2D) nanomaterials with atomic or molecular thicknesses have attracted great research interest for gas sensing applications. This was due to the distinctive physical, chemical, and electronic properties related to their ultrathin thickness, which positively affect the gas sensing performances. This feature article discusses the latest dev...

Carbon nanotubes have long been described as rolled-up graphene sheets. It is only fairly recently observed that longitudinal cleavage of carbon nanotubes, using chemical, catalytical and electrical approaches, unzips them into thin graphene strips of various widths, the so-called graphene nanoribbons. In contrast, rolling up these flimsy ribbons into tubes in a real experiment has not been pos...

Understanding the transformation of graphene derivatives by natural amphiphiles is essential for elucidating the biological and environmental implications of this emerging class of engineered nanomaterials. Using rapid discrete-molecular-dynamics simulations, we examined the binding of graphene and graphene oxide with peptides, fatty acids, and cellulose, and complemented our simulations by exp...

The cover picture shows the electrochemical detection of dihydroxy benzene by nano-electrocatalysts based on carbonaceous nanomaterials (i.e., carbon nanotubes, graphene, and their derivatives) non-carbonaceous metal-organic frameworks, molecular imprinted polymers, other nanomaterials). See Reviews Part 1 (DOI:10.1002/tcr.202100043) 2 (DOI:10.1002/tcr.202100044) Md. Abdul Aziz, A. J. Saleh Aha...

Examining interactions between nanomaterials and cell membranes can expose underlying mechanisms of nanomaterial cytotoxicity and guide the design of safer nanomedical technologies. Recently, graphene has been shown to exhibit potential toxicity to cells; however, the molecular processes driving its lethal properties have yet to be fully characterized. We here demonstrate that graphene nanoshee...
