Mechanistic Origins of Chemo‐Mechanical Instability and Failure in Solid‐State Lithium‐Sulfur Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...

Strengthening school coexistence through ancestral knowledge

open access: yesRevista Iberoamericana de la Educación
The general objective of this research project is to strengthen the school coexistence of the students of the Jaime Roock Educational Institution, El Caimito, rural area of the district of Buenaventura, through a pedagogical strategy based on ancestral knowledge. A qualitative approach of participatory action research is used.

Ga–O–Pt Electronic Bridges Bypass Single‐Site Constraints for pH‐Universal Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Well‐defined oxygen‐bridged Ga–O–Pt catalysts are constructed for pH‐universal hydrogen evolution, highlighting the relationship between oxygen‐bridged electronic coupling, rapid surface hydrogen redistribution, and superior catalytic performance. ABSTRACT Single‐site descriptors often fail to capture hydrogen evolution on heterometallic interfaces ...

Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Utilizing the Metastability of Spidroins as a Strategy for Improving Mechanical Properties of Biomimetic Spider Silk Fibers

open access: yesAdvanced Functional Materials, EarlyView.
Phase transitions are central for the assembly of recombinant silk proteins into fibers. Soluble protein can transition into condensed states such as condensates and gels. These states are metastable and evolve in a time‐dependent way. Metastability depends on the protein sequence, and this relationship can be used to enhance the mechanical properties ...

Local Dispersal and Coexistence in a Metacommunity Model with Trophic Structure

open access: yes, 2007
One of the major goals of ecology is to understand the mechanisms which promote species coexistence. Much progress has been made in recent years in understanding how spatial processes influence diversity.

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.
