Carbon nanohorns (sometimes also known as nanocones) are conical carbon
nanostructures constructed from an sp2 carbon sheet. Nanohorns require no metal catalyst …

The carbon nanotube (CNT) represents one of the most unique inventions in the field of
nanotechnology. CNTs have been studied closely over the last two decades by many …

The tensile strengths of individual multiwalled carbon nanotubes (MWCNTs) were measured
with a “nanostressing stage” located within a scanning electron microscope. The tensile …

Wrinkling is a ubiquitous phenomenon in two-dimensional membranes. In particular, in the
large-scale growth of graphene on metallic substrates, high densities of wrinkles are …

Carbon is a unique and very versatile element which is capable of forming different
architectures at the nanoscale. Over the last 20 years, new members of the carbon …

Carbon is an element with extremely versatile bonding properties and theoretical
calculations have suggested the possible existence of several hundred structural allotropes …

Defects are usually seen as imperfections in materials that could significantly degrade their
performance. However, at the nanoscale, defects could be extremely useful since they could …

Carbon nanotubes subject to large deformations reversibly switch into different
morphological patterns. Each shape change corresponds to an abrupt release of energy …

We employ scanning probe microscopy to reveal atomic structures and nanoscale
morphology of graphene-based electronic devices (ie, a graphene sheet supported by an …

We have conducted pulling and bending tests on individual carbon nanotubes in-situ in a
transition electron microscope. Based on our observation of the force required to break the …
