Mechanical properties of suspended graphene sheets
TLDR
In this article, the Young's modulus of stacks of graphene sheets suspended over photolithographically defined trenches in silicon dioxide was measured using an atomic force microscope, with measured spring constants scaling as expected with the dimensions of the suspended section, ranging from 1to5N∕m.Abstract:
Using an atomic force microscope, we measured effective spring constants of stacks of graphene sheets (less than 5) suspended over photolithographically defined trenches in silicon dioxide. Measurements were made on layered graphene sheets of thicknesses between 2 and 8nm, with measured spring constants scaling as expected with the dimensions of the suspended section, ranging from 1to5N∕m. When our data are fitted to a model for doubly clamped beams under tension, we extract a Young’s modulus of 0.5TPa, compared to 1TPa for bulk graphite along the basal plane, and tensions on the order of 10−7N.read more

Stretching and Breaking of Ultrathin MoS2
TL;DR: In this paper, the stiffness and breaking strength of monolayer MoS2, a new semiconducting analogue of graphene, was investigated. But the results were limited to the case of single and bilayer membranes, and the strength of strongest membranes was only 11% of its Young's modulus.

Catalysis with two-dimensional materials and their heterostructures
TL;DR: Recent advances in the use of graphene and other 2D materials in catalytic applications are reviewed, focusing in particular on the catalytic activity of heterogeneous systems such as van der Waals heterostructures (stacks of several 2D crystals).

Raman Scattering from High-Frequency Phonons in Supported n-Graphene Layer Films
TL;DR: Results of room-temperature Raman scattering studies of ultrathin graphitic films supported on Si (100)/SiO2 substrates are reported, and both the first- and second-order Raman spectra show unique signatures of the number of layers in the film.

Single spin detection by magnetic resonance force microscopy
TL;DR: The long relaxation time of the measured signal suggests that the state of an individual spin can be monitored for extended periods of time, even while subjected to a complex set of manipulations that are part of the MRFM measurement protocol.

A tunable carbon nanotube electromechanical oscillator
TL;DR: The electrical actuation and detection of the guitar-string-like oscillation modes of doubly clamped nanotube oscillators are reported and it is shown that the resonance frequency can be widely tuned and that the devices can be used to transduce very small forces.
