Dual‐Atom Dopants Activated Ruthenium Single‐Atom Alloy Boosting Hydrogen Evolution Electrocatalysis in Proton Exchange Membrane Water Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
Ni1‐Bi1 dual‐atom dopants are achieved for activating Ru lattices without blocking noble atoms. This model exhibits an ultralow overpotential of 11.4 mV and superb stability at 10 mA cm−2 toward hydrogen evolution reaction, enabling a proton exchange membrane water electrolyzer that needs only 2.233 V to reach 3.0 A cm−2 and operates stably at 1.0 A cm−

Le mythe de l’« icône » : anachronisme et désir moderniste

open access: yesPerspective
The term “icon”, commonly used today to designate a sacred image, especially in the context of so-called Byzantine art, conceals a recent historiographical construction that is far removed from its Medieval meanings and uses. Our essay traces the history

Cultural prototypes and dimensions of honor [PDF]

open access: yes, 2013
Research evidence and theoretical accounts of honor point to differing definitions of the construct in differing cultural contexts. The current studies address the question “What is honor?” using a prototype approach in Turkey and the northern US ...

Service or Devotion? Motivation Patterns of Russian Researchers

open access: yes, 2017
Most current studies of high-skilled personnel argue that the intrinsic personal motivation is their main feature and this motivation has a non-linear connection with external management actions.

Modulating Interfacial Potential Gradients in Metal−Carbon Catalysts via Phase‐Engineering for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
It is elucidated that phase engineering of cobalt modulates the interfacial potential gradients of cobalt–carbon electrocatalysts, enhancing the intrinsic electrocatalytic performance. Modulating the dominant crystalline phase of cobalt from a hexagonal close‐packed to a face‐centered cubic enriches the electron density of carbon shells, thereby ...

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...

Quelle place pour les masculinités dans la spiritualité béguinale ? Penser les béguins au regard des études de genre

open access: yesPerspectives Médiévales
While it is common to consider Beguine spirituality as predominantly, if not exclusively, feminine, several literary texts written in the oïl language during the 13th century offer the possibility of a different perspective, designating members of ...

Il pharmakos nelle fonti antiche e nella Storia delle religioni. Alcune valutazioni critiche

open access: yesMythos, 2018
What is meant by the Greek word pharmakos? Was it a purification ritual or a sacrifice? What are the origins of this ceremony? One or two individuals – in case of social, religious, political crisis, or a natural disaster – were expelled from the ...

Strengthening Devotion

open access: yesGrounded Theory Review: An International Journal, 2020
The experiences of parents rearing an autistic child(ren) framed an exploration of caregiver well-being using Glaser’s classic grounded theory. The theory delineates struggles, stress, and self-growth through service.
