Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

EVOLUÇÃO DO CAPITAL SOCIAL EMPREENDEDOR DOS SPIN-OFFS UNIVERSITÁRIOS

Regepe Entrepreneurship and Small Business Journal, 2012
Apesar de a literatura do campo do empreendedorismo reconhecer a evolução do capital social, ao longo do processo de criação de uma empresa, as pesquisas até aqui realizadas registraram, em geral, a estrutura da rede em certo momento e não as mudanças ...

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

Designing Stable Periodic Magnetization Textures by Tailoring Anisotropies and Applying Geometrical Transformation

Advanced Functional Materials, EarlyView.
This work explores the possibility to design stable periodic magnetization textures by transforming a 2D film into a rolled‐up 3D architecture and back. In case of an isotropic exchange‐biased layer architecture, the magnetization encoded in the 3D state evolves into a spin‐spiral pattern with controlled periodicity after unrolling.

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

Advanced 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
