Digitizing the Filtration Interface: A Smart, Modular Janus Wood Platform for Self‐Reporting Oil/Water Remediation

open access: yesAdvanced Functional Materials, EarlyView.
This work developed a smart Janus wood membrane integrating asymmetric wettability with built‐in electrical sensing for oil‐water separation. The membrane achieved > 99.5% separation efficiency and high flux by leveraging wood's natural anisotropic pore structure.

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

COVID-19: Export controls and international cooperation

open access: yes, 2020
As part of their response to the COVID-19 pandemic, many countries have restricted exports of medical products with the aim to allocate domestic supplies to national healthcare systems and citizens.

EU Core Groups: Specialisation and Division of Labour in EU Foreign Policy. CEPS Working Document, No. 252, 19 October 2006 [PDF]

open access: yes, 2006
Close foreign policy cooperation among a limited number of EU member states is generally looked upon with suspicion as it is associated with ‘directoires’ of large member states.

Russia and Myanmar – Friends in Need?

open access: yesJournal of Current Southeast Asian Affairs, 2015
To date, few political scientists have researched the political, economic, and social relationships between Russia and Myanmar. The two countries, which at first glance may seem to have little in common, have intensified their cooperation in recent years.

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

open access: yesAdvanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

PARTITIONING GAMES WITH RESTRICTED COOPERATION

open access: yes
Partitioning games and games with restricted cooperation are general games which include large classes of different and important cooperative games. In this paper we combined both concepts and prove a generalization of the theorem of Quint [1991] which ...

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Coalition structures induced by the strength of a graph [PDF]

open access: yes
We study cooperative games associated with a communication structure which takes into account a level of communication between players. Let us consider an undirected communication graph : each node represents a player and there is an edge between two ...
