MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

¿Mujeres presbítero o mujeres diácono?

open access: yesEstudios Eclesiásticos, 1980
La ordenación ministerial de la mujer es una controversia de largo alcance dentro de la Iglesia. A raíz del ascenso social y laboral de la mujer ha surgido la cuestión de por qué no darles más relevancia en la dirección de la Iglesia.

La epilepsia desde el punto de vista canónico

open access: yesEstudios Eclesiásticos, 1958
Este estudio trata la epilepsia desde el punto de vista canónico y en relación a la preparación del sacerdocio y su ministerio. En general, desde el Concilio de Elvira de principios del siglo IV no se ha abordado este asunto de manera explícita.

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

open access: yesAdvanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...
