Site-selective surface enhanced Raman scattering study of ligand exchange reactions on aggregated Ag nanocubes

Francesco Stellacci, Paulo Henrique Jacob Silva, Zekiye Pelin Güven, Evangelia-Nefeli Athanasopoulou

Surface modification of ligand protected nanoparticles (NPs) can be driven by ligand exchange reactions (LER). Little is known about the mechanism of this reaction, especially when the particles are not spherical. Here, we use the intrinsic hot spots gener ...

Cyclodextrin Modulated Type I Collagen Self-Assembly to Engineer Biomimetic Cornea Implants

Francesco Stellacci, Evangelia-Nefeli Athanasopoulou

Collagen-rich tissues in the cornea exhibit unique and highly organized extracellular matrix ultrastructures, which contribute to its high load-bearing capacity and light transmittance. Corneal collagen fibrils are controlled during development by small le ...

Scanning Probe Microscopy Characterization of Organic Self-Assembled Monolayers

Evangelia-Nefeli Athanasopoulou

As technology advances, surface coatings become more and more important to assure materials performances. In recent years, molecular coatings have found larger acceptance and uses. Among them, self-assembled monolayers (SAMs) are attractive because they ar ...

Bimodal atomic force microscopy for the characterization of thiolated self-assembled monolayers

Francesco Stellacci, Quy Ong Khac, Nikolaos Nianias, Evangelia-Nefeli Athanasopoulou

Surface coatings are becoming an integral part of materials. In recent years, molecular coatings have found larger acceptance and uses. Among them, self-assembled monolayers (SAMs) are attractive due to their inherent versatility, manufacturability, and sc ...

From Nano- to Micrometer Scale: The Role of Antisolvent Treatment on High Performance Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Francesco Stellacci, Peng Gao, Evangelia-Nefeli Athanasopoulou, Kyung Taek Cho, Sanghyun Paek, Giulia Grancini, Yi Zhang, Pascal Alexander Schouwink

To date, antisolvent treatment has become one of the most important means to fabricate high efficiency perovskite solar cells (PSCs); however, the few reported antisolvents have not been analyzed on a uniform platform, and there is hitherto no clear reason ...
