New strategy suggested to boost performance of all-solid-state ion-selective electrodes

Researchers propose a novel strategy to improve all-solid-state ion-selective electrodes by designing transduction layer materials with high hydrophobicity and large capacitance. The study reveals that ion-selective membranes constrain capacitive material performance, hindering sensor reliability.

Turning step-growth into chain-growth with click polymerization

Researchers developed a controlled 'living' click polymerization system to achieve well-defined polymers with narrow dispersity, enabling bidirectional synthesis of ABA-type block copolymers. The method leverages copper-catalyzed azide–alkyne cycloaddition and initiators to selectively drive monomer addition in a controlled manner.

Source criticism in school requires more than isolated interventions

A new study from Uppsala University shows that short teaching interventions on disinformation have no long-term impact on students' ability to distinguish between credible and misleading news. However, students who valued democratic ideals highly were better at identifying true and false information. The study suggests that isolated le...
