The transmittance and sheet resistance of the copper nanowire(CuNW)/poly(methyl methacrylate) (PMMA) composite transparent electrode (TE) are not significantly altered as compared with those of the CuNW TE. This figure shows the transmittance spectra and photographs of the CuNW TE (left image) and CuNW/PMMA composite TE (right image) (grey line: CuNW TE; orange line:CuNW/PMMA composite TE).

The controlled preparation of oriented large-area high-quality single-crystal pentagonal graphene domains on Cu foils by chemical vapor deposition (CVD) is reported. The crystalline structure of the underlying Cu grain and the high hydrogen partial pressure contribute to the formation of pentagonal graphene. This work provides a deeper understanding on the mechanism of graphenegrowth.

Large biomolecules, including drugs, are unable to cross the blood-brain barrier (BBB); therefore, multi-functionalization of the surface of nanoparticles constitutes a promising strategy for overcoming this obstacle. Moreover, alternative administration routes could be utilized to improve BBB crossing by nanoparticles:Lung administration of nanoparticles designed for Alzheimer*s disease therapy is a suitable, feasible, and non-invasive strategy for reaching the brain and exerting therapeutic effects in an animal model of Alzheimer*s disease.
