Molecular modeling of cracks at interfaces in nanoceramic composites

William Curtin, Fabio Pavia

Toughness in Ceramic Matrix Composites (CMCs) is achieved if crack deflection can occur at the fiber/matrix interface, preventing crack penetration into the fiber and enabling energy-dissipating fiber pullout. To investigate toughening in nanoscale CMCs, d ...

Electrostatic-Consistent Coarse-Grained Potentials for Molecular Simulations of Proteins

Matteo Dal Peraro, Michele Cascella, Matteo Thomas Degiacomi, Davide Alemani, Enrico Spiga

We present a new generation of coarse-grained (CG) potentials that account for a simplified electrostatic description of soluble proteins. The treatment of permanent electrostatic dipoles of the backbone and polar side-chains allows to simulate proteins, p ...

Molecular Modeling of Bacterial Nanomachineries

Matteo Thomas Degiacomi

Proteins have the ability to assemble in multimeric states to perform their specific biological function. Unfortunately, characterizing experimentally these structures at atomistic resolution is usually difficult. For this reason, in silico methodologies a ...

Interfacial sliding in carbon nanotube/diamond matrix composites

William Curtin, Fabio Pavia

Carbon matrix carbon nanotube (CNT) composites have a broad range of applications because of the exceptional mechanical properties of both matrix and fibers. Since interfacial sliding plays a key role in determining the strength and toughness of ceramic co ...

Molecular Simulation Studies of Separation of CO2/N-2, CO2/CH4, and CH4/N-2 by ZIFs

Berend Smit

In this work, molecular simulations were performed to evaluate the separation performance of two typical zeolitic imidazolate frameworks (ZIFs), ZIF-68 and ZIF-69, for CO2/N2, CO2/CH 4, and CH4/N2 mixtures. To do this, we first identified a suitable force ...

An Atomistic Simulation Method for Oxygen Impurities in Aluminium Based on Variable Charge Molecular Dynamics

Andreas Elsener

Impurities are known to have a significant impact on materials properties. In particular, the presence of impurities can change mechanical properties and stabilize the microstructure by reducing grain growth and recrystallization processes. In the past ato ...
