Ultra-high performance of DLC-coated Si3N4 rings for mechanical seals
Mercedes Vila,J.M. Carrapichano,José R. B. Gomes,Sergio S. Camargo,Carlos A. Achete,Rui F. Silva +5 more
TL;DR: In this paper, a self-mated pure diamond-like carbon (DLC) ring-on-ring tribosystem was proposed for sealing Si3N4-based ceramics.

Properties of tantalum oxynitride thin films produced by magnetron sputtering: The influence of processing parameters
Daniel Cristea,Daniel Cristea,D. Constantin,D. Constantin,Aurel Crisan,C.S. Abreu,C.S. Abreu,José R. B. Gomes,N.P. Barradas,Eduardo Alves,C. Moura,Filipe Vaz,Luís Miguel Cunha +12 more
TL;DR: In this article, a set of tantalum oxynitride (TaNxOy) thin films were prepared by varying the reactive gases flow rate, using a N2/O2 gas mixture with a concentration ratio of 17:3.

Molecular Simulations of the Synthesis of Periodic Mesoporous Silica Phases at High Surfactant Concentrations
Szu Chia Chien,Germán Pérez-Sánchez,Germán Pérez-Sánchez,José R. B. Gomes,M. Natália Sias Soeiro Cordeiro,Miguel Jorge,Scott M. Auerbach,Peter A. Monson +7 more
TL;DR: In this paper, the formation mechanism of periodic mesoporous silica over a wide range of cationic surfactant concentrations was studied and it was shown that the liquid-crystal templating mechanism is not viable because the preformed liquid crystal collapses as silica monomers are added into the solution.

Molecular simulation of silica/surfactant self-assembly in the synthesis of periodic mesoporous silicas.
TL;DR: It is shown that silica promotes the formation of larger aggregates than in a simple surfactant/water solution, by comparing the self-assembly of cationic surfactants in the presence and absence of silicates.
Multiscale Model for the Templated Synthesis of Mesoporous Silica: The Essential Role of Silica Oligomers
Germán Pérez-Sánchez,Germán Pérez-Sánchez,Szu Chia Chien,José R. B. Gomes,Natália Cordeiro,Scott M. Auerbach,Peter A. Monson,Miguel Jorge +7 more
TL;DR: In this article, a multiscale simulation strategy was proposed to describe the molecular-level processes behind the formation of silica/surfactant mesophases in the synthesis of templated MCM-41 materials.
