Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Twin Crystal Moiré Metasurfaces for Crossing Flat‐Band Transport

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces twin crystal moiré metasurfaces, breaking in‐plane symmetry to enable reconfigurable acoustic wave manipulation. By adjusting the twin angle and interlayer twist angle, various combinations of hyperbolic, flat bands, and elliptic states can be synthesized in the system.

'Keeping the bastards honest': the promise and practice of freedom of information legislation

open access: yes, 2006
In the last decade the number of countries that have enacted Freedom of Information (FOI) laws have increased dramatically. In many respects FOI laws have become a democratic 'right of passage'. No FOI, no 'proper' democracy.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a
