Abstract: Recently, a new family of 2D materials with exceptional optoelectronic properties has stormed into the scene of nanotechnology, the transition metal dichalcogenides (e.g., MoS2). In contrast with graphene, which is a zero band gap semiconductor, many of the single layered materials from this family show a direct band-gap in the visible range. [..] Read more

Abstract: In the present work we report on the influence of repetitive anodization cycles upon the dimensions and morphology of self-organized TiO2 nanotube layers.

Abstract: Nanocomposites with exceptional properties are promising materials that gain a market share during the current years. Multi-walls Carbon nanotubes (MWCNTs) can be used as a filler for polymeric matrix; however, their attractive forces lead to their agglomeration and affect the properties of the final nanocomposite.

Abstract: In this work chitosan based nanoparticles were prepared and modified by a star-shaped carboxy-terminated polylactide (S-PLA) in order to reduce the doxorubicin burst effect in physiological solution.S-PLA was prepared by polycondensation reaction using pentetic acid as a core molecule and methansulfonic acid as catalyst and linked to chitosan backbone through coupling reaction. Afterwards, chitosan-(S-PLA) modified nanoparticles loaded with doxorubicin were prepared by polyelectrolytes complexation method using dextran sulphate sodium salt as polyanion.Results show nanoparticles with diameter in the range 100-200 nm, spherical shape and ζ-potential between 27-35 mV.
