Assessing TiO2/Chitosan‐Based Hydrogels for Water Remediation: Sunlight‐Driven Degradation of Antibiotics in Water

Advanced Materials Interfaces, EarlyView.
Chitosan–TiO2 composite hydrogels combine adsorption of organic pollutants with photocatalysis, allowing to remove 85% of a broadly diffused antibiotic (sulfamethoxazole) under direct sunlight irradiation, opening great promises for point‐of‐use, outdoor applications.

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection

Advanced Materials Interfaces, EarlyView.
A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.
