Mechanisms of Temperature‐Dependent Hysteresis in Freestanding BaTiO3/MoS2 Heterostructures

open access: yesAdvanced Science, EarlyView.
Freestanding ferroelectric BaTiO3 membranes are combined with monolayer MoS2 into 2D field‐effect transistors. At room temperature they provide ultrahigh‐κ gating with steep subthreshold swing and minimal hysteresis. Upon cooling, strong ferroelectric switching produces two stable memory states with long retention times.

Beyond‐Classical Ferroelectric Metamaterials: 3D‐Printed Planar Lattices With Programmable Electro–Thermo–Mechanical Coupling

open access: yesAdvanced Science, EarlyView.
Planar ferroelectric lattices with rationally‐tailored topology and polarization achieve programmable piezoelectric and pyroelectric properties. Analytical modeling, homogenization, and experiments collectively demonstrate enhanced and tunable longitudinal, transverse, and shear piezoelectric responses, together with substantially improved ...

Modélisation de la dynamique de l'habitat des jeunes stades de saumon atlantique (Salmo salar) de la rivière Ashuapmushuan (Québec, Canada)

open access: yesKnowledge and Management of Aquatic Ecosystems, 1994
La technique de modélisation des microhabitats sert à évaluer l'impact des divers usages de l'eau sur la disponibilité de l'habitat des poissons. Cependant, un aspect négligé par ces modèles est que les variations de débit peuvent affecter aussi la ...

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

open access: yesAdvanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

The Economic Consequences of Quebec Sovereignty [PDF]

open access: yes
This paper reviews the issues that would arise if Quebec were to separate from Canada. It also presents quantitative estimates of the likely orders of magnitude of their economic impact both on Quebec and the Rest of Canada.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Role of the Media in the Quebec Language Portfolio [PDF]

open access: yes, 2000
In the Province of Quebec, and in particular on the island of Montreal, large communities of the French-speaking Quebecois majority and the English-speaking Quebecker minority have historically co-inhabited peacefully.
