“…The thermal, 24 electronic, 25 and mechanical 26 properties of SWCNT vary substantially depending on the SWCNT diameters and chiral angles. [25][26][27][28] Five single wall carbon nanotubes with distinct chiralities were evaluated during this study, Figure 1(b). While these nanotubes have different diameters and lengths, they all consist of 600 carbon atoms each.…”

The potential use of carbon nanotubes based composites as structural materials in hazardous radiation environments calls for investigating their radiation damage resistance. In this study molecular dynamics simulations were utilized to elucidate the keV protons-induced processes in composites comprising carbon nanotubes and polyethylene chains. In particular, the investigation is focused on revealing the effect of the carbon nanotubes chiralities on the composite radiation damage tolerance and the composite's surviving stiffness. Radiation was emulated by adding an explicit energy term to that calculated via a force field which drove the systems away from thermodynamics equilibrium. It was observed that the damage accumulates rapidly during the early stages of the simulation and it consisted mostly of polyethylene chain scissoring and generation of small hydrocarbon radicals. Evident by the number of defragmentation and the endured elastic stiffness, composites incorporating carbon nanotubes with zigzag or armchair structure were found to be more resistant to radiation damage than those utilizing nanotubes with intermediate chiralities.

“…Chiral vectors such as (n1, n2) represent paths on a honeycomb lattice sheet in which the starting and ending points of the vector on the Nano-sheet have coincided. 33,34 If in the chiral vector of CNT one of n1 or n2 is equal to zero it is called zigzag, while if n1 is equal to n2 or |n1-n2| is equal to a multiple of three, it is named as Armchair, and the rest of combinations are known as Chiral. 35 Different types of CNTs have been shown in Fig.…”

By using CNFET technology in 3a 2 nm node using a proposed SQI gate, two split bit-lines QSRAM architectures have been suggested to address the issue of increasing demand for storage capacity in IoT/IoVT applications. Peripheral circuits such as a novel quaternary to binary decoder for QSRAM have been offered. Various simulations on temperature, supply voltage, and access frequency have been done to evaluate and ensure the performance of the proposed SQI gate, suggested cells, and quaternary to binary decoder. Moreover, 1000 Monte-Carlo analyses on the fabrication parameters have been done to classify read and write delay and standby power of proposed cells along with PDP of proposed quaternary to binary decoder. It is worth mentioning that the PDP of the proposed SQI gate, decoder, and average power consumption of suggested HF-QSRAM cell reached 0.92 aJ, 4.13 aJ, and 0.15 µW, respectively, which are approximately 80%, 91%, and 33% improvements in comparison with the best existing designs in the literature.

Effect of Chirality and Length on the Penetrability of Single-Walled Carbon Nanotubes into Lipid Bilayer Cell Membranes

The ability of carbon nanotubes to enter the cell membrane acting as drug-delivery vehicles has yielded a plethora of experimental investigations, mostly with inconclusive results because of the wide spectra of carbon nanotube structures. Because of the virtual impossibility of synthesizing CNTs with distinct chirality, we report a parametric study on the use of molecular dynamics to provide better insight into the effect of the carbon nanotube chirality and the aspect ratio on the interaction with a lipid bilayer membrane. The simulation results indicated that a single-walled carbon nanotube utilizes different time-evolving mechanisms to facilitate their internalization within the membrane. These mechanisms comprise both penetration and endocytosis. It was observed that carbon nanotubes with higher aspect ratios penetrate the membrane faster whereas shorter nanotubes undergo significant rotation during the final stages of endocytosis. Furthermore, nanotubes with lower chiral indices developed significant adhesion with the membrane. This adhesion is hypothesized to consume some of the carbon nanotube energy, thus resulting in longer times for the nanotube to translocate through the membrane.
