introduction: carbon nanotubes (cnts) have shown enormous potential in neuroscience. nerve growth factor (ngf)-cnts complex promotes the neuronal growth, however, the underlying mechanism(s) have remained elusive. based on the interplay between ngf and the endocannabinoid system, involvement of the neuroprotective endocannabinoid, 2-arachidonoyl glycerol (2-ag), was investigated in the mechanis...

The recent application of nanotechnology to structural materials is a promising way to produce new strong materials that exceed current limitations. Grain-size refinement is considered as one of the most effective strengthening methods of materials. At the same time, the addition of carbon nanotubes (CNTs) in a material is known to be more effective than conventional reinforcements. Here, CNT/C...

Al is one of the most widely applicable metallic materials due to its advanced properties. However, main drawback strength, which relatively low compared ferrous alloys. This issue may be resolved using different approaches. In present work, a heterostructure substrate with modified surface carbon nanotubes (CNTs) was studied. obtained laser-oriented deposition technique. The results showed sli...

Carbon nanotubes (CNTs) are being applied with increasing frequency for advanced soldering. They have excellent mechanical, electrical, and thermal properties primarily used to reinforce lead-free solders. This paper discusses the strengthening mechanism of CNTs, introduces preparation methods CNT composite solders, focuses on review tin-based solders reinforced unmodified CNTs metal-modified C...

The electrical properties of carbon nanotubes (CNT) cement-based composites have been modeled in previous works by circuit models or homogenization theories. An alternative approach is the use an effective medium theory with induced polarization: In this work, a new model based on generalized polarization (GEMTIP) cylindrical inclusions proposed. presented results and discussion show its applic...

Since their discovery in 1991, carbon nanotubes (CNTs) have attracted growing interest in view of their unique mechanical and physicochemical properties, and have successfully been applied in microelectronics such as memory devices, switches, supercapacitors, and in the biomedical area as drug-delivery devices and biosensors. The oriented assembly of CNTs on an electrode surface offers further ...

Carbon nanotube (CNT) polymer nanocomposites are one of the most promising materials due to their remarkable mechanical properties as well electrical conductivity, which offers capability monitoring deformation and damage composite structures by measuring related conductivity variations. However, quantifying distribution CNTs inside material remains a challenge with respects both experimental n...

In spite of significant insolubility and toxicity, carbon nanotubes (CNTs) erupt into the biomedical research, and create an increasing interest in the field of nanomedicine. Single-walled CNTs (SWCNTs) are highly hydrophobic and have been shown to be toxic while systemically administrated. Thus, SWCNTs have to be functionalized to render water solubility and biocompatibility. Herein, we introd...

Characteristics of nanosized Pt electro-catalyst deposited on carbon nanotubes (CNTs) were studied with CO-stripping voltammogram and chronoamperometry measurements. The CNTs were pretreated by oxidation in HNO3, mixed HNO3 + H2SO4 and H2SO4 + K2Cr2O7 solution, respectively, to enable surface modification. Well-homogenized Pt particles (average size: 3 nm) were loaded onto the pretreated CNT sa...

BACKGROUND Carbon nanotubes (CNTs) have found wide success in circuitry, photovoltaics, and other applications. In contrast, several hurdles exist in using CNTs towards applications in drug delivery. Raw, non-modified CNTs are widely known for their toxicity. As such, many have attempted to reduce CNT toxicity for intravenous drug delivery purposes by post-process surface modification. Alternat...
