Colloidal Cu2O nanoparticles can exhibit both photocatalytic activity under visible light illumination and resonant Mie scattering, but, for their practical application, they have to be immobilized on a substrate. Butterfly wings, with complex hierarchical photonic nanoarchitectures, constitute promising substrate the immobilization of tuning optical properties. The native wax layer covering wing scales Polyommatus icarus butterflies was removed by simple ethanol pretreatment prior...

Abstract Hybrid materials based on carbon nanotubes continue to attract considerable interest due the broad variety of both cages outside and encapsulated species inside. This review focuses organic molecules as guests in single-walled nanotube hosts. The majority results presented here has been attained recent years by various methods optical spectroscopy, complemented transmission electron microscopy. These spectroscopic yield information electronic structure, well dynamic processes...

Growing graphene nanoribbons from small organic molecules encapsulated in carbon nanotubes can result products with uniform width and chirality. We propose a method based on encapsulation of 1,2,4-trichlorobenzene the liquid phase subsequent annealing. This procedure results several tens nanometers long. The presence was proven by Raman spectra both macroscopic samples nanoscale tip-enhanced scattering high-resolution transmission electron microscopic images.

Successful encapsulation of sexithiophene (6T) molecules by two different methods is presented: sublimation filling at 400 °C and nanoextraction from supercritical carbon dioxide (sc‐CO 2 ) 50 °C. Differences in the Raman spectra samples indicate thermally induced polymerization during filling, increasing electronic conjugation length chains inside nanotubes. The thermal reaction proven heating sc‐CO ‐filled nanotubes after encapsulation. Although thiophene chain upon heating, no signatures...

Graphene nanoribbons are prepared inside boron nitride nanotubes by liquid phase encapsulation and subsequent annealing of 1,2,4‐trichlorobenzene. The product is imaged with high‐resolution transmission electron microscopy, characterized optical absorption Raman spectroscopy. Carbon‐containing material detected the energy‐dispersive X‐ray spectroscopy (EDS) scanning microscopy (STEM). observed structures twist under beam characteristic features appear in spectra.

A biosurfactant, n-hexadecyl-1-beta-D-maltopyranoside (HMP), and a broadly used cationic surfactant, hexadecyltrimethylammonium (HDTMA), were as montmorillonite clay modifiers for an in silico study to explore the most stable adsorption sites trapping of chromate (CrO4−2) contaminant. Monte Carlo searches have been find low energy configurations substrate with adsorbate identify possible sites. There was found that CrO4 proximity polar head HDTMA surfactant at less than 3 Å from Ca2+...
