Cryogenic electron tomography to determine thermodynamic quantities for nanoparticle dispersions

Francesco Stellacci, Davide Demurtas, Quy Ong Khac, Xufeng Xu, Francesca Olgiati, Ting Mao, Paulo Henrique Jacob Silva, Anna Murello

Here we present a method to extract thermodynamic quantities for nanoparticle dispersions in solvents. The method is based on the study of tomograms obtained from cryogenic electron tomography (cryoET). The approach is demonstrated for gold nanoparticles ( ...

Nature-Inspired Circular-Economy Recycling for Proteins: Proof of Concept

Francesco Stellacci, Laure Menin, Luc Patiny, Shiyu Cheng, Daniel Ortiz Trujillo, Anna Murello, Simone Giaveri

The billion tons of synthetic-polymer-based materials (i.e. plastics) produced yearly are a great challenge for humanity. Nature produces even more natural polymers, yet they are sustainable. Proteins are sequence-defined natural polymers that are constant ...

Water interactions with complex surfaces

Anna Murello

The solvent accessible surface area of proteins is very complex, mainly because it is composed of domains with different degrees of affinity for water. The domains nature and arrangement determine both the interactions of the proteins with water (and there ...

Determination and evaluation of the nonadditivity in wetting of molecularly heterogeneous surfaces

Francesco Stellacci, Michele Ceriotti, Sylvie Roke, Quy Ong Khac, Halil Ibrahim Okur, David Mark Wilkins, Zhi Luo, Anna Murello, Filip Kovacik

The interface between water and folded proteins is very complex. Proteins have "patchy" solvent-accessible areas composed of domains of varying hydrophobicity. The textbook understanding is that these domains contribute additively to interfacial properties ...

Amorphous CaCO3: Influence of the Formation Time on Its Degree of Hydration and Stability

Francesco Stellacci, Huachuan Du, Esther Amstad, Camelia Borca, Mathias Steinacher, Anna Murello

Calcium carbonate (CaCO3) is one of the most abundant biominerals that is prevalent in rocks and often used as a structural material in marine animals. Many of these natural CaCO3-based materials display excellent mechanical properties that are difficult t ...
