À compter du 6 février, nous devrons procéder à une interruption temporaire du dépôt de documents dans Papyrus, y compris les thèses et mémoires, le temps d’effectuer une migration de la plateforme vers le service de dépôt institutionnel canadien Scholaris. Le jeudi 6 février, le site sera inaccessible à partir de 7h00 et il sera de retour en fin d’après-midi. Par la suite, tout le contenu de Papyrus sera accessible durant les travaux qui devraient durer environ deux semaines. Pour toute question, contactez depot@bib.umontreal.ca -------- As of February 6, we will be temporarily suspending the deposit of documents in Papyrus, including theses and dissertations, while we migrate the platform to the Canadian institutional deposit service Scholaris. On Thursday February 6, the site will be inaccessible from 7:00 a.m. until late afternoon. Afterwards, all Papyrus content will be accessible during the work, which is expected to last around two weeks. If you have any questions, please contact depot@bib.umontreal.ca

Data management plan - CERC in light-matter interactions
(2024-05-14)This data management plan shows how the data from the CERC on light-matter interactions directed by Prof. Carlos Silva Acuña will be collected, organized, named, stored, backed up, preserved, and shared. -
Raman-based mapping and depth-profiling of the relaxation state in amorphous silicon
(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 ... -
Formation of crystalline Si1-xGex top layers by ion implantation in crystalline silicon
(Elsevier, 2023-02-27)Semiconductor nanocrystals incorporated in a dielectric film are widely studied as potential candidates to exceed the Shockley-Queisser theoretical conversion limit of photovoltaic cells. In this context, Ge nanocrystals embedded in SiO2 films seem to ... -

In-plasma analysis of plasma–surface interactions
(American Institute of Physics, 2023)During deposition, modification, and etching of thin films and nanomaterials in reactive plasmas, many active species can interact with the sample simultaneously. This includes reactive neutrals formed by fragmentation of the feed gas, positive ions, ... -
Molecular interactions of tannic acid with proteins associated with SARS-CoV-2 infectivity
(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 ... -
Insights on the effect of water content in carburizing gas mixtures on the metal dusting corrosion of iron
(Elsevier, 2021-12-07)Constituents of syngas, such as water, carbon monoxide and sulfides, can cause the degradation of the steel pipes they move through, leading to carbon dusting and corrosion. In spite of considerable attention to this process, many questions remain ... -
Corilagin and 1,3,6-Tri-O-galloyl-β -D-glucose : potential inhibitors of SARS-CoV-2 variants
(2021-06-28)The COVID-19 disease caused by the virus SARS-CoV-2, first detected in December 2019, is still emerging through virus mutations. Although almost under control in some countries due to effective vaccines that are mitigating the worldwide pandemic, the ... -
Zirconia-titania-doped tantala optical coatings for low mechanical loss Bragg mirrors
(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 ... -
Polyphenol-peptide interactions in mitigation of Alzheimer’s disease : role of biosurface-induced aggregation
(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
(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 ... -
Diffusion mechanism of bound Schottky defect in magnesium oxide
(American Physical Society, 2021-03-25)In simple ionic crystals, intrinsic point defects must satisfy electrical neutrality and exist as Schottky defects. In magnesium oxide (MgO), a Schottky defect is then a combination of anionic and cationic vacancies. Since vacancies are charged, the ... -
Engineering visible light emitting point defects in Zr-implanted polycrystalline AlN films
(American Institute of Physics, 2020-12-22)We have investigated the impact of thermal annealing gaseous atmosphere of argon, nitrogen, and forming gas on the structural and optical properties of thin polycrystalline AlN films subjected to high-energy zirconium ions implantation. X-ray diffraction, ... -
Mitigating Alzheimer’s disease with natural polyphenols: a review
(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 ... -
Comparison of three radio-frequency discharge modes on the treatment of breast cancer cells in vitro
(Institute of Electrical and Electronics Engineers, 2019)Non-thermal plasmas (NTPs) are known for their ability to induce thermal-free cytotoxic effects on cancer cells.
