Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

open access: yesAdvanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

open access: yesAdvanced Functional Materials, EarlyView.
A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

open access: yesAdvanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

Programmable In‐Situ Interactions Between Resins and Photopolymerized Structures for Seamlessly Integrated Optical Manufacturing of Microlenses

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...

Risk and Social Democracy [PDF]

open access: yes
‘Risk’ has become a central theme in 21st-century policy thinking. The fact that individuals and families are vulnerable to a wide range of social, economic and other risks, and that collective action is needed to help reduce and manage these risks, has ...

Egypt and the Middle East: Democracy, Anti-Democracy and Pragmatic Faith [PDF]

open access: yes, 2016
In this article, I discuss prospects for democracy in the Middle East. I argue, first, that some democratic experiments—for instance, Egypt under Mohammed Morsi—are not in keeping with etymological and historical meanings of

The Global Hinterland of Social DemocracyOn the Limitations of Norwegian Welfare Capitalism

open access: yesNordisk Välfärdsforskning
Every instantiation of decommodifying welfare capitalism relies on a global hinterland, an exterior space for which commodification still remains the rule and whose function is to service the national interior of a social democratic polity. Taking Norway
