Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

BMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

Pulse-resolved Classification and Characteristics of Long-duration Gamma-Ray Bursts with Swift-BAT Data. I. Precursors versus Main Bursts

The Astrophysical Journal Supplement Series
Many long gamma-ray bursts (GRBs) exhibit complex prompt emission structures with multiple temporally distinct episodes, such as early-time precursors preceding the main burst. Whether these subcomponents share the same physical origin and classification

Applications of Biomaterials in Separators for Secondary Batteries

Carbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Advancing the Classification of Gamma-Ray Bursts Using Machine Learning. I. Gamma-Ray Bursts with Extended Emission

The Astrophysical Journal
Gamma-ray bursts (GRBs) with extended emission (EE) challenge traditional GRB classification schemes, yet their origins remain unknown. In this paper, we employ unsupervised machine learning methods to classify Swift EE GRBs using multidimensional ...

Designing a Triplet 2‐Formylphenylnitrene With Fast Tunneling Reactivity

Chemistry – A European Journal, EarlyView.
A 3‐CF3 substituent accelerates tunneling in triplet 2‐formylphenylnitrene, making its reactivity in cryogenic matrices too fast for conventional IR spectroscopic detection. Bringing this chemistry to low‐temperature solutions allows suppression of intrinsic nitrene dimerization through faster cyclization, which even outcompetes the 1,4‐H shift ...

Highly Polarized 1,4‐Dihydropyrrolo[3,2‐b]Pyrroles: From Synthesis to Photophysics and Two‐Photon Induced Polymerization

Chemistry – A European Journal, EarlyView.
Quadrupolar, centrosymmetric 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPP) possessing two five‐membered rings and highly polarized architecture are not emissive, but they are good photosensitizers in two‐photon induced polymerization. ABSTRACT A series of ladder‐type, highly polarized functional dyes possessing 1,4‐dihydropyrrolo[3,2‐b]pyrrole (DHPP ...
