HRTEM investigation confirms the crystallographic structure of graphene. The investigated layers show flat transmittance spectra across the visible and near-infrared region. The charge transfer resistance of the graphene-based film was analysed by electrochemical impedance measurement. The obtained results ...
Graphene oxide layerDye-sensitised solar cellsHigh-resolution electron microscopyThe influence of the graphene-based counter electrode on the structure, optical properties and electrocatalytic activity of dye-sensitised solar cells (DSCC) was analysed. The graphene and reduced graphene oxide were ...
It has been found that physical features such as length, diameter, alignment, composition, crystalline structure, purity, doping, defect density, as well as growth direction and nature of facets are all essential in determining the emission and absorption properties of nanowires, and therefore in de...
Centrifugation, vibration and shear flow have all provided increases in osteogenesis through external modulation of the force imposed on the cell structure. The use of vibration as a mechanotransductive stimulus has been explored with varied vibrational parameters14,15,16. Vibration of periodontal ...
Firstly, the intricacy of the pore structure makes the transport processes in porous media very complex. Pores tend to have irregular surfaces and some of them even make dead ends. These factors influence the flow and transport behaviour significantly. Another difficulty of studying transport ...
and electronic structure calculations investigating the interaction of gold nanoparticles with graphene and graphite substrates.The results presented here have significant implications for future research on the chemical and physical properties of gold-based nanoparticles and are of interest to many researchers...
Finally, MTT assay showed that the coated MWSB nanocomposites on 3T3 cells were very much biocompatible at a concentration up to 100 g/mL, which is an evidence of MWSB reduced cytotoxicity.Similar content being viewed by others A pH-sensitive nanocarrier based on BSA-stabilized graphene-chitosan...
Increasing the MWCNTs concentration changes the PCL crystalline structure. • Scaffold containing 3 wt% of MWCNTs presents a compressive modulus close to cancellous bone Abstract Carbon nanotubes(CNTs) with exceptional physical and chemical properties are attracting significant interest in the field oftiss...
Reactions that form these links usually occur post-translation, stabilising folding and providing structure for a number of proteins9,10,11. The cell regularly controls disulfide bonds between thiol groups, alternately guiding species through reduction and oxidation12. Redox potentials and oxidative ...
In this work we studied the influence of experimental conditions (vs. substrate temperature, working pressure and inert sustaining gases) on the structure evolution of carbon films, from an almost amorphous material to nano-clustered graphene particles. The carbon films were grown by Pulsed Laser ...
