From Molecules to Bioaggregates: Unraveling the Photoexcitation Dynamics of Intracellularly Self‐Assembled Thiophene‐Based Fibers

open access: yesSmall Science, EarlyView.
Cell‐guided self‐assembly of thiophene based molecules inside living cells produces photostable, biocompatible nanofibers exhibiting J‐like excitonic coupling and stimulated emission. Integrated spectroscopic and quantum‐chemical analyses reveal unique photophysical behavior and low phototoxicity, positioning these supramolecular structures as ...

High‐Resolution Heterogeneous Hydrogel Printing Using a Home Projector

open access: yesSmall Methods, EarlyView.
This study presents a high‐resolution hydrogel printing method using photoreactive polyvinyl alcohol bearing styrylpyridinium groups (PVA‐SbQ) and a standard digital projector to spatially control light exposure. This approach enables precise tuning of crosslinking, allowing the integration of soft/tough and high/low swelling regions within a single ...

Femtoliter Batch Reactors for Nanofluidic Scattering Spectroscopy Analysis of Catalytic Reactions on Single Nanoparticles

open access: yesSmall Methods, EarlyView.
A transient 4.8 femtoliter batch reactor is created within a micro‐ and nanofluidic system with the help of symmetric N2‐streams. The catalytic activity of a single lithographic gold nanoparticle in the reactor is monitored via nanofluidic scattering spectroscopy (NSS), revealing dynamic chemical changes of Fluorescein in the presence of NaBH4 as a ...

Robust Passivation of Perovskite Using Rubidium Iodide for Efficient Photovoltaic Applications under Various Illumination Environments

open access: yesSmall Structures, EarlyView.
A robust defect passivation strategy for perovskite films using rubidium iodide (RbI) is reported. The RbI treatment simultaneously mitigates defects across the buried interface, within the bulk, and on the surface of perovskite films. This enhances crystallinity, suppresses ion migration, and reduces phase segregation.

Harmonizing NAD+ metabolism with CeMOF nanozyme to orchestrate intraocular pressure modulation for glaucoma treatment

open access: yesVIEW, EarlyView.
Our findings demonstrate that NAD+ metabolism dysregulation contributes to elevated intraocular pressure in glaucoma. Supplementation with NAD+ precursors reduces IOP by alleviating oxidative stress, cellular senescence, and extracellular matrix deposition.

Lanthanide Coordination Polymers Obtained from Ln(OH)3 and 2‐Furoic Acid for Ln3+‐Based Luminescence in the Visible and Near‐Infrared Range

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
A series of isotypic lanthanide 1D‐coordination polymers and a 2D‐network with the 2‐furoate anion was synthesized from lanthanide hydroxides Ln(OH)3 (Ln = Nd3+, Eu3+, and Ho3+) as starting materials. The different lanthanide ions exhibit 4f‐based emission, including near infrared emission for Nd3+.

Mother of Holiness: Phoebe Palmer's Maternal Grief, Silence, and Spiritual Leadership in her Spiritual Narrative

open access: yesJournal of Religious History, EarlyView.
This article expands upon a central aspect of Holiness evangelist Phoebe Palmer's (1807–1874) theology, which has been only tangentially mentioned by scholars: her gendered identity of motherhood. It first considers how Palmer narrated the deaths of her first two sons in her spiritual narrative The Way of Holiness as divine punishment for her ...

Superoxide Activates Ferroptosis via the Haber‐Weiss Reaction and Enhances Age‐Related Macular Degeneration

open access: yesAging Cell, EarlyView.
Superoxide activates ferroptosis through the Haber‐Weiss reaction and contributes to the development of age‐related macular degeneration. MnSOD‐depleted RPE cells are susceptible to blue light‐induced ferroptosis. MnSOD deficiency promotes Hsp70‐driven ubiquitin‐mediated degradation of GPX4.
