Thermal behavior of aminotrimethoxysilanphosphonate functionalized onto styrene-divinylbenzene copolymer

open access: yesInternational Journal of Polymer Analysis and Characterization, 2020
The chlorometylated styrene–divinylbenzene copolymer with different percent of divinylbenzene (code: S-6.7 DVB, S-12DVB, and S-15DVB) was functionalized with 3-hydroxybenzaldehyde for obtaining intermediated polymers. The aminotrimethoxysilanphosphonate groups were grafted by one-pot reactions in tetrahydrofuran using three components: polymers grafted

A Degradable Device for Sustainable Capillary Blood Sampling

open access: yesAdvanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

Temperature Thresholds Govern Microbial‐Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Electrodialysis of LiPF6 in Aqueous Solution for Wastewater Treatment in Hydrometallurgical Recycling of Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Hydrometallurgical recycling of lithium‐ion batteries produces wastewater containing PF6− and Li+, which must be removed and recovered, respectively. This study pioneers electrodialysis using anion exchange membrane and cation exchange membrane to separate PF6− and Li+.

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, Volume 37, Issue 49, December 10, 2025.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Functional Groups‐Driven Molecular Design for Broad‐Spectrum Clusteroluminescence in Scalable Monodisperse Polymer Microspheres

open access: yesAggregate, Volume 6, Issue 12, December 2025.
This study developed a scalable strategy for fabricating monodisperse cluster‐luminescent polymer microspheres via functional group engineering. The microspheres exhibit broad emission (400–700 nm) and low fluorescence coefficient of variation (CV < 3%), fulfilling requirements for routine flow cytometer calibration.
