Electrically, Chemically, and Photonically Powered Torsional and Tensile Actuation of Hybrid Carbon Nanotube Yarn Muscles
Guest-filled, twist-spun carbon nanotube yarns are designed as electrolyte-free muscles that provide fast, high-force, large-stroke torsional and tensile actuation and can solve the problems of speed and lifetime.

The results show that these nano-oscillators are dynamically stable when the radii difference values between inner and outer tubes are of approximately 3.4 A.
Geometric and electronic structure of carbon nanotube networks: ‘super’-carbon nanotubes
Structures of the so-called super-carbon nanotubes are proposed. These structures are built from single walled carbon nanotubes connected by Y-like junctions forming a ‘super’-sheet that is then…
Chemical Vapor Deposition of Monolayer Rhenium Disulfide (ReS2)
Initial field-effect transistor characteristics are evaluated, which highlight the potential in being used as an n-type semiconductor.
Gigahertz nanomechanical oscillators based on carbon nanotubes
We report molecular dynamics studies of carbon nanotubes as mechanical gigahertz oscillators. Our results show that different oscillatory regimes exist but that sustained oscillations are possible…
Graphene to graphane: a theoretical study
This work has investigated the role of H frustration (breaking the H atoms' up and down alternating pattern) in graphane-like structures and shows that a significant percentage of uncorrelated H frustrated domains are formed in the early stages of the hydrogenation process leading to membrane shrinkage and extensive membrane corrugations.
Hierarchically buckled sheath-core fibers for superelastic electronics, sensors, and muscles
Using theory, the complementary effects of an increase in muscle length and a large positive Poisson’s ratio on torsional actuation and electronic properties are quantitatively explained.
Polymerization of 5,6‐indolequinone: A view into the band structure of melanins
We present for the first time a study of finite and infinite polymers of 5,6‐indolequinone. We show that the band structure of the infinite polymer presents semiconductor characteristics, and that…
High Toughness in Ultralow Density Graphene Oxide Foam
Here, the scalable synthesis of low‐density 3D macroscopic structure of graphene oxide (GO) interconnected with polydimethylsiloxane (PDMS) is reported. A controlled amount of PDMS is infused into…
Prediction of the hydrogen storage capacity of carbon nanoscrolls
Classical grand-canonical Monte Carlo simulations were performed to investigate the equilibrium hydrogen storage capacity of carbon nanoscrolls. The results show that hydrogen molecules can be…
