Abstract The development of low-cost, high-activity, and durable integrated bifunctional flexible air electrodes for use in Zn-air batteries is both challenging important. We report a simple scalable electropolymerization method used to prepare an electrode material comprising heavily N-doped carbon covering single-walled nanotube (N/C-SWCNT) networks. resulting core/shell structure the hybrid ...

This study examines the potential of using nanofluids in solar thermal energy systems. Nanofluids are known to exhibit high convection heat transfer coefficients, low specific heat, and density, making them ideal for improving performance However, this computational investigates application Cattaneo-Christov flux on cylindrical surfaces carbon nanotube (CNT) hybrid nanofluids, use a solar-power...

Tailoring the density of random single-walled carbon nanotube (SWCNT) networks is of paramount importance for various applications, yet it remains a major challenge due to the insufficient catalyst activation in most growth processes. Here we report on a simple and effective method to maximise the number of active catalyst nanoparticles using catalytic chemical vapor deposition (CCVD). By modul...

Aqueous single-walled carbon nanotube dispersions are often made using polymers from the pluronic family of amphiphilic block copolymers; however, relatively few studies have been conducted using small-angle neutron scattering techniques to discover the mechanism by which they act. SANS results reported here show that a relatively simple core-shell cylinder model can be used to fit data success...

Highly sensitive detection of a Pb(2+)-Cu(2+) mixture using gold nanoparticles patterned on single-walled carbon nanotube (AuNP-SWCNT) film is reported. The gold nanoparticles were deposited electrochemically on carbon nanotube film using a cyclic voltammetry technique. The film showed a homogeneous size and density that could be easily controlled by the potential scanning cycle and gold precur...

Solution-processed single-walled carbon nanotube (SWCNT) thin-film transistors (TFTs) in the research stage often have large active areas. This results unusual gate leakage currents with high magnitudes that vary applied voltages. In this paper, we report an improved structure for solution-processed SWCNT-based TFTs. The current is resolved by patterning SWCNT layer to confine it channel region...

An integrated cellulose polymer concentrator/single-walled carbon nanotube (SWCNT) sensing system is demonstrated to detect benzene, toluene, and xylenes (BTX) vapors. The sensing system consists of functionalized cellulose as a selective concentrator disposed directly on top of a conductive SWCNT sensing layer. Functionalized cellulose concentrator (top layer) selectively adsorbs the target an...

Single-walled carbon nanotube (SWCNT) transparent conducting films (TCFs) were fabricated for the electrodes of organic light-emitting diodes (OLEDs); three types of film were studied. The as-prepared SWCNT TCFs displayed a relatively low sheet resistance of 82.6 Ω/sq at 80.7 T% with a relatively large surface roughness of 30 nm. The TCFs were top-coated with poly(3,4-ethylenedioxythiophene):po...

Hybrid heterojunction solar cells based on silicon and single-walled carbon nanotube (SWCNT) thin films have a simple structure their manufacture employ low-temperature processes. Moreover, progress has been rapid during the last decade, wherein efficiency of combining hydrogenated amorphous (a-Si:H) SWCNTs film increased from 0.03% to 8.80%. Here, we present comprehensive overview state-of-the...

In this study concept of experimental design is successfully applied for the determination of optimum condition to produce PP/SWCNT (Polypropylene/Single wall carbon nanotube) nanocomposite. Central composite design as one of experimental design techniques is employed for the optimization and statistical determination of the significant factors influencing on the tensile modulus and yield stres...
