A hierarchical nanostructured carbon nanofiber–In2S3 photocatalyst with high photodegradation and disinfection abilities under visible light
Photocatalytic degradation of pollutants under visible light provides a new door to solve the water contamination problem by utilizing free and renewable sunlight. The search for highly efficient photocatalysts with ...
Synthesis of β-d-glucopyranuronosylamine in aqueous solution : kinetic study and synthetic potential
A systematic study of the synthesis of β-d-glucopyranuronosylamine in water is reported. When sodium d-glucuronate was reacted with ammonia and/or volatile ammonium salts in water a mixture of β-d-glucopyranuronosylamine ...
Unidirectional surface plasmons in nonreciprocal graphene
We demonstrate theoretically the existence of unidirectional surface plasmons in the nonreciprocal graphene-based gyrotropic interfaces. We show that a unidirectional frequency range is raised under a static external ...
A graphene nanoribbon network and its biosensing application
Graphene oxide nanoribbons (GONRs) have been prepared by chemically unzipping multiwalled carbon nanotubes (MWCNTs). Thin-film networks of GONRs were fabricated by spray-coating, followed by ...
Biocompatible, uniform, and redispersible mesoporous silica nanoparticles for cancer-targeted drug delivery in vivo
Engineering multifunctional nanocarriers for targeted drug delivery shows promising potentials to revolutionize the cancer chemotherapy. Simple methods to optimize physicochemical characteristics and surface composition ...
Stable cyclic performance of nickel oxide–carbon composite anode for lithium-ion batteries
Nickel oxide (NiO) directly grown on nickel foam is regarded as a promising lithium ion battery anode material which shows good cyclic and rate performances with a theoretical specific capacity of 718 mAhg−1. In this study, ...
Sputtered nickel oxide on vertically-aligned multiwall carbon nanotube arrays for lithium-ion batteries
We fabricated nickel oxide (NiO) on vertically-aligned multiwall carbon nanotube (MWCNT) arrays (MWCNT/NiO) as an electrode for lithium-ion batteries. The specific capacity of 864.8 mAhg−1 at the rate of 143.6 mAg−1 for ...
Germanium coated vertically-aligned multiwall carbon nanotubes as lithium-ion battery anodes
The performance of polycrystalline and amorphous germanium (Ge) as anode active materials for lithium-ion batteries was studied systematically. Polycrystalline Ge on vertically-aligned multiwall carbon nanotube (MWCNT) ...
Surface modification of PLLA nano-scaffolds with laminin multilayer by LbL assembly for enhancing neurite outgrowth
In this study, PLLA nanofibers are fabricated by electrospinning and their surfaces are modified by laminin/chitosan (LN/CS) polyelectrolyte multilayer. Surface C/N ratio determined by XPS analysis quantitatively indicates ...
Plasmonic nanowire continuum light source
Optically pumped gold nanowire, 330 nm in diameter imbedded into silicate optical fiber produces broadband, highly collimated radiation (in the range 470-900 nm) with divergence of less than 4 mrad.
