One aspect of carbon nanotube (CNT) synthesis that remains an obstacle to realize industrial mass production is the growth efficiency. Many approaches have been reported to improve the efficiency, either by lengthening the catalyst lifetime or by increasing the growth rate. We investigated the applicability of dwell time and carbon flux control to optimize yield, growth rate, and catalyst lifet...

Recent advances in nanotechnology present synthetic bioinspired materials to create new controllable microenvironments for stem cell growth, which have allowed directed differentiation into specifi c lineages. [ 1 , 2 ] Carbon nanotubes (CNTs), one of the most extensively studied nanomaterials, can provide a favorable extracellular environment for intimate cell adhesion due to their similar dim...

Temporal and spatial changes in neurotransmitter concentrations are central to information processing in neural networks. Therefore, biosensors for neurotransmitters are essential tools for neuroscience. In this work, we applied a new technique, corona phase molecular recognition (CoPhMoRe), to identify adsorbed polymer phases on fluorescent single-walled carbon nanotubes (SWCNTs) that allow fo...

An aqueous solution containing photosynthetic reaction centers (RCs), membrane scaffold proteins (MSPs), phospholipids, and single-walled carbon nanotubes (SWCNTs) solubilized with the surfactant sodium cholate (SC) reversibly self-assembles into a highly ordered structure upon dialysis of the latter. The resulting structure is photoelectrochemically active and consists of 4-nm-thick lipid bila...

The integration of low-dimensional materials with optical waveguides presents promising opportunities for enhancing light manipulation in passive photonic circuits. In this study, we investigate the potential aerosol-synthesized single-walled carbon nanotube (SWCNT) films silicon nitride circuits as a basis developing integrated optics devices. Specifically, by measuring response SWCNT-covered ...

Single-walled carbon nanotube encapsulated in boron nitrite (SWCNT@BNNT) is a novel nanomaterial with one-dimensional van der Waals (1D-vdW) heterostructure. In this paper, we demonstrated that the SWCNT@BNNT has an enhanced optical power tolerance compared to of pristine SWCNT while exhibiting saturable absorption properties. Under intensity 13kW/cm2, lifetime found be 2,270 times longer than ...

The electron transfer dynamics and electrocatalytic behaviour of ferrocene-terminated self-assembled monolayers (SAMs), co-adsorbed with single-walled carbon nanotubes (SWCNTs) on a gold electrode, have been interrogated for the first time. Ferrocene monocarboxylic acid (FMCA) or ferrocene dicarboxylic acid (FDCA) was covalently attached to the cysteamine (Cys) monolayer to form Au-Cys-FMCA and...

A flexible, transparent, single-walled carbon nanotube (SWCNT) film electrode was prepared by vacuum filtering methods, followed by photolithographic patterning of a photoresist polymer on the SWCNT surface. The morphology of the SWCNT film electrode surface was characterized using a field-emission scanning electron microscope coupled to an energy-dispersive X-ray spectrophotometer. The electro...

Background & objectives: Xylene, which can pollute the water sources, is widely used as a solvent in insecticide manufacture, dye and leather and other industries. Adsorption is one of the most common processes used to treat the contaminated aqueous solutions by xylene. Therefore, the aim of this study was to compare the xylene removal efficiency and adsorption isotherms of magnetic nanoparticl...
