Fatigue resistance is a key property of the service lifetime structural materials. Carbon nanotubes (CNTs) are one strongest materials ever discovered, but measuring their fatigue challenge because size and lack effective measurement methods for such small samples. We developed noncontact acoustic resonance test system investigating behavior centimeter-long individual CNTs. found that CNTs have excellent resistance, which dependent on temperature, time to fracture dominated by creation first defect.
Abstract Carbon nanotubes (CNTs) are promising candidates for smart electronic devices. However, it is challenging to mediate their bandgap or chirality from a vapor-liquid-solid growth process. Here, we demonstrate rate-selected semiconducting CNT arrays based on interlocking between the atomic assembly rate and of CNTs. Rate analysis confirms Schulz-Flory distribution which leads various decay rates as length increases in metallic Quantitatively, nearly ten-fold faster CNTs spontaneous...
The nature of chaos is in that elusive flow an advanced order out our vision. It wise to take advantage after recognizing or modifying its unique fractal properties. Here, a magnetron weaving strategy was developed for producing chaotic but monochromatic carbon nanotube tangles (CNT-Ts) under Kelvin–Helmholtz instability (KHI). self-similarity characteristic facilitated individual ultralong CNTs manipulate their entropy-driven geometry, resulting ∼104 μm2 CNT-Ts with variable curvature...
Ultralong carbon nanotubes (CNTs) exhibit extraordinary mechanical tensile strength of over 100 GPa, and a Young's modulus 1 TPa. CNTs are considered to be one the strongest materials ever found overwhelming advantages for storing energy. In particular, great potential fabricating flywheels store kinetic energy with both high density power density, as discussed by Rufan Zhang, Fei Wei, co-workers in article number 1800680.
Abstract The emergent nanofluidics promotes the exploration of special hydrodynamics fluid transport in a nano-sized flow domain 1–3 . Water, most common nature and human society, will form ordered structures 4–7 by reducing hydrogen bonding ultra-fast carbon nanotubes 8–16 However, such behaviors have only been reported tubes with nano- or micro-meter lengths far away from what can be considered as macroscopic scales. Here we establish mass spectroscopy system to detect super-transport...
