  • Mitigating Alzheimer’s disease with natural polyphenols: a review 

    Gaudreault, Roger; Mousseau, Normand (Bentham Science, 2019-03-14)
    According to Alzheimer’s Disease International (ADI), nearly 50 million people worldwide were living with dementia in 2017, and this number is expected to triple by 2050. Despite years of research in this field, the root cause and mechanisms responsible ...

  • Molecular interactions of tannic acid with proteins associated with SARS-CoV-2 infectivity 

    Haddad, Mohamed; Gaudreault, Roger; Sasseville, Gabriel; Nguyen, Phuong Trang; Wiebe, Hannah; Van De Ven, Theo; Bourgault, Steve; Mousseau, Normand; Ramassamy, Charles (MDPI, 2022-02-27)
    The overall impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on our society is unprecedented. The identification of small natural ligands that could prevent the entry and/or replication of the coronavirus remains a pertinent ...

  • Polyphenol-peptide interactions in mitigation of Alzheimer’s disease : role of biosurface-induced aggregation 

    Gaudreault, Roger; Hervé, Vincent; Van De Ven, Theo; Mousseau, Normand; Ramassamy, Charles (IOS Press, 2021-05-08)
    Alzheimer’s disease (AD) is the most common age-related neurodegenerative disorder, responsible for nearly two-thirds of all dementia cases. In this review, we report the potential AD treatment strategies focusing on natural polyphenol molecules ...

  • Pressure effect on diffusion of carbon at the 85.91◦ 100 symmetric tilt grain boundary of α-iron 

    Rahman, Md Mijanur; El-Mellouhi, Fedwa; Bouhali, Othmane; Becquart, Charlotte; Mousseau, Normand (American Physical Society, 2021-04-19)
    The diffusion mechanism of carbon in iron plays a vital role in carburization processes, steel fabrication, and metal dusting corrosion. In this paper, using the kinetic activation-relaxation technique (k-ART), an off-lattice kinetic Monte Carlo algorithm ...

  • Raman-based mapping and depth-profiling of the relaxation state in amorphous silicon 

    Lussier, Alexandre W.; Bourbonnais Sureault, David; Chicoine, Martin; Martel, Richard; Martinu, Ludvik; Roorda, Sjoerd; Schiettekatte, François (American Institute of Physics, 2024-02-09)
    We show that the micro-scale variations in the relaxation state of amorphous silicon (aSi) can be well-identified by Raman mapping over hundreds or thousands of µm2 in 1-2 hours. Pure and relaxed a-Si is obtained by self-implantation in crystalline ...

  • Spectrum simulation of rough and nanostructured targets from their 2D and 3D image by Monte Carlo methods 

    Schiettekatte, François; Chicoine, Martin (2015-09)
    Corteo is a program that implements Monte Carlo (MC) method to simulate ion beam analysis (IBA) spectra of several techniques by following the ions trajectory until a sufficiently large fraction of them reach the detector to generate a spectrum. Hence, ...

  • Zirconia-titania-doped tantala optical coatings for low mechanical loss Bragg mirrors 

    Lalande, Émile; Lussier, Alexandre W.; Lévesque, Carl; Ward, Marianne; Baloukas, Bill; Martinu, Ludvik; Gabriele, Vajente; Billingsley, Garilynn; Ananyeva, Alena; Bassiri, Riccardo; Fejer, Martin M.; Schiettekatte, François (American Vacuum Society, 2021-06-10)
    The noise caused by internal mechanical dissipation in the high refractive index amorphous thin films in dielectric mirrors is an important limitation for gravitational wave detection. The objective of this study is to decrease this noise spectral ...
