Molecular Preorganization Unlocks Reversible Solid‐State Photoconversion in Dianthrylnaphthalene‐Based Molecular Solar Thermal Systems

open access: yesAngewandte Chemie, EarlyView.
Three dianthrylnaphthalenes were synthesized and investigated for molecular solar thermal (MOST) energy storage. Naphthyl‐based bridging units preorganize the two anthracene moieties face‐to‐face, leading to improved photoisomerization quantum yield (QY) and unlocked bidirectional photoswitching in the solid state compared to previously reported ortho ...

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Un terrorisme que no va poder ser: el cas d’El complot dels anells

open access: yesStudia Romanica Posnaniensia, 2015
This article analyzes the construction of El complot dels anells (The plot of the rings), a Catalan political fiction artifact that was created as both a film and a novel in 1988. To this end, not only the fundamental sociopolitical and cultural contexts

Highly Flexible and Conformable ZnO/FeGa Magnetoelectric Heterostructures for Skin wound Healing

open access: yesAdvanced Science, EarlyView.
The magnetic field‐induced electric field generated by a highly flexile ZnO(piezoelectric)/FeGa(magnetostrictive) magnetoelectric heterostructure embedded in the low Young's modulus elastomer PDMS has been used to stimulate the wound healing processes.

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

open access: yesAdvanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

Giant Direct Magnetoelectric Effect in Nanocomposite CoFe2O4:PVDF‐TrFE Thin Films

open access: yesAdvanced Science, EarlyView.
A novel three‐step grow‐etch‐fill fabrication approach creates structured cobalt ferrite/ferroelectric polymer nanocomposites with high interfacial areas. Driven by efficient strain‐mediated coupling, this crystalline system achieves a giant room‐temperature magnetoelectric coefficient nearly two orders of magnitude higher than other CFO/PVDF‐TrFE thin

Greener Solvents for the Photoisomerization and Catalytic Heat Release of a Norbornadiene‐Based Molecular Solar Thermal Energy Storage System

open access: yesAdvanced Science, EarlyView.
A Molecular Solar Thermal (MOST) system combining a scalable norbornadiene–quadricyclane photoswitch, a biodegradable solvent, propylene carbonate, and noble and first‐row metal catalysts, is presented. Propylene carbonate boosts photoisomerization quantum yield by 25% compared to toluene, prolongs energy storage by an additional 15 days, and enables ...

Improving High‐Temperature Operational Stability of Inverted Perovskite Solar Cells Through MXene Heat‐Dissipating Layers

open access: yesAdvanced Science, EarlyView.
MeO‐2PACz‐functionalized MXene nanosheets create a thermally conductive buried interface in inverted perovskite solar cells. The interface improves heat spreading, suppresses defects and ion migration, and strengthens charge extraction, extending T80 at 65°C from 141 to 687 h while maintaining competitive efficiency.
