The grafting of drugs to the single-walled carbon nanotube (SWCNT) was attained by the initial conversion of carboxylic groups in SWCNT to corresponding acyl chlorides. The active acyl chlorides in SWCNT were subsequently mixed with chemotherapeutic agents having NH, NH2, and OH functional groups to afford the formation of relevant amide and ester, respectively. The covalently grafted drugs to ...

Abstract Free vibration of a single-walled carbon nanotube (SWCNT) embedded in an elastic medium is studied on the basis nonlocal Timoshenko beam model. Influences slenderness ratios, boundary conditions, atomic structures and stiffness natural frequencies mode shapes SWCNT are examined. The effect significant for higher modes with small ratio soft medium, it softens except fundamental frequenc...

Airbrushed single walled carbon nanotube (SWCNT) thin films with sheet resistivity <1 kX/ sq. and transparency >80% are used as electrodes for pentacene and regioregular poly(3hexylthiophene) (P3HT) thin-film transistors (TFTs). Airbrushed SWCNT electrodes show low contact resistance in a bottom-contact configuration, comparable to (in the case of P3HT) or lower than (in the case of pentacene) ...

In the article number 2200357 Tomonaga Ueno, and co-workers report an ultralight single-walled carbon nanotube (SWCNT) aerogel for low-frequency sound absorption, with a hierarchical porous structure high-modulus framework. The Biot–Johnson–Champoux–Allard model indicates significant effect of high elastic modulus SWCNT on absorption.

Disposable, selective and low-cost carbon nanotube modified electrodes were fabricated for the electrochemical detection of neonicotinoid insecticide, Clothianidin (CLT). Almost 2 folds’ increase at Clothianidin reduction signal was obtained by using single-walled carbon nanotube modified electrodes (SWCNT-PGE) compared to unmodified electrodes. These nanomaterials modified electrodes developed...

Herein, we present the fabrication of multiplexed single-walled carbon nanotube (SWCNT) devices, where selected chiralities were separately immobilized on one chip with single-tube precision. Each chirality was subsequently electrically measured individually. Specifically, (6,5) and (7,5) SWCNT species isolated via aqueous two-phase polymer systems, after which dielectrophoresis used to precise...

Noncovalent polymer-single walled carbon nanotube (SWCNT) conjugates have gained recent interest due to their prevalent use as electrochemical and optical sensors, SWCNT-based therapeutics, and for SWCNT separation. However, little is known about the effects of polymer-SWCNT molecular interactions on functional properties of these conjugates. In this work, we show that SWCNT complexed with rela...
