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 covalent functionalization of carbon nanotubes (CNTs) is a basic but important chemistry that can modify their physicochemical properties, resolve their poor dispersion capability, and improve their capacitance to enable their use as high-energy supercapacitors. However, the relationship between functional groups on the CNT surface and their capacitive characteristics has not yet been explo...

In this study, noncovalent functionalization of single-walled carbon nanotubes (SWCNTs) with phospholipid-polyethylene glycols (Pl-PEGs) was performed to improve the solubility of SWCNTs in aqueous solution. Two kinds of PEG derivatives, ie, Pl-PEG 2000 and Pl-PEG 5000, were used for the PEGylation process. An experimental design technique (D-optimal design and second-order polynomial equations...

We developed a novel detection method for osteopontin (OPN), a new biomarker for prostate cancer, by attaching a genetically engineered single-chain variable fragment (scFv) protein with high binding affinity for OPN to a carbon nanotube field-effect transistor (NT-FET). Chemical functionalization using diazonium salts is used to covalently attach scFv to NT-FETs, as confirmed by atomic force m...

Controlling the chemistry on the surface of new carbon materials is a key factor to widen the range of their applicability. In this paper we show a grafting methodology of polyalkylamines to the surface of carbon nanomaterials, in particular, carbon nanotubes and a carbon black. The aim of this work is to reach large degrees of covalent functionalization with hyperbranched polyethyleneimines (H...

The increasing rise in the rate of both anthropogenic CO2 emissions and atmospheric CO2 concentration, combined with an evolving understanding of what this means for global climate change both now, and in the future, has increased the need for novel technologies for CO2 capture from large point sources. Current industry standards involve the use of amine solvents, which have a large parasitic l...

Abstract The increasing emission of carbon dioxide (CO 2 ) to the atmosphere has gained worldwide concern due its main contribution climate changes, global warming, and greenhouse effect. Numbers technologies have been carried out remove this hazardous gas from environment such as absorption, adsorption, membrane separation, cryogenic biological process. Due limitation current absorption techni...

An efficient metal-free visible light-driven two-step domino reaction towards new bioactive tetrahydroisoquinoline-butenolide hybrid compounds was developed for the first time. Combination of fluorescein as photosensitizer and thiourea an additive found to be most effective way promote aerobic amine oxidation/vinylogous Mannich sequence with yields up 97% a broad substrate scope. Both experimen...

Graphene oxide (GO) is a promising 2D material with complex chemical structure which characterization remains as challenge. The widely-accepted of GO includes epoxides, hydroxyls and carboxylic acids. Recently, alkene groups have been used for selective functionalization. Despite the different efforts that exist to elucidate exact structure, composition main functionalities fairly limited. By k...
