Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

open access: yesResponsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Designing for unanticipated uses: How product attributes shape community‐led exaptation

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Users often discover new uses for products that firms may later commercialize, which we call community‐led exaptation. We examine how product attributes shape users' discovery of new functions versus new functionalities. Using 1925 IKEA product hacks, we find that modularity increases the likelihood of new functions.
