Clusterization‐Triggered Emission from Cellulose‐Based Luminophores in Dilute Aqueous Solution through Imine Formation

Advanced Functional Materials, EarlyView.
Clusterization‐triggered emission is realized in dilute aqueous solution by introducing imine linkages into cellulose‐based luminophores. Imine functionalization creates O/N‐rich, hydrogen‐bonded clustered microenvironments that stabilize emissive states and restrict molecular motions. Luminescence is tunable by amine type and multiplicity.

Low‐Fraction Irregular Inclusions Trigger Large Compression Stiffening in Biopolymer Hydrogels

Advanced Functional Materials, EarlyView.
Irregular inclusions at low filler fractions trigger large compression stiffening in biopolymer hydrogels. By promoting contact‐network formation under compression, these inclusions induce non‐affine rearrangements, stretch surrounding fibers, and provide parallel load‐bearing pathways.

Vulnerability of dynamic genetic conservation units of forest trees in Europe to climate change [PDF]

, 2015
A transnational network of genetic conservation units for forest trees was recently documented in Europe aiming at the conservation of evolutionary processes and the adaptive potential of natural or man‐made tree populations. In this study, we quantified

Engineering of Crystallinity to Amplify Chiroptical Activity of TiO2 Nanohelices for Enhancing Dissymmetric Circularly Polarized Photocatalysis

Advanced Functional Materials, EarlyView.
Enhancing crystallinity through thermal annealing leads to amplifying the chiroptical activity of TiO2 nanohelices (NHs) fabricated by glancing angle deposition, ascribed to the suppression of charge trapping. The enhanced chiroptical activity can be converted into pronounced dissymmetric photocatalytic kinetics of circularly polarized photocatalysis ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Ultrasensitive Detection of Porcine Epidemic Diarrhea Virus Infections Using Multivalent DNA Nanostructure‐Enabled Lateral Flow Assay

Advanced Healthcare Materials, EarlyView.
A multivalent DNA nanostructure‐enabled lateral flow assay was developed for rapid, ultrasensitive detection of porcine epidemic diarrhea virus (PEDV) nucleocapsid protein. Designer net‐shaped DNA nanostructures (DNA‐Net) presenting PEDV‐specific aptamers achieved ~1000‐fold enhanced binding, enabling detection of viral copies with Ct ≤ 37.42 within 10
