Adsorbent Materials for Hydrocarbons Removal by Geopolymerization of Halloysite Clay Nanotubes Filled Within Chitosan Matrix

open access: yesAdvanced Materials Interfaces, EarlyView.
Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...

Moisture‐Adaptive Triboelectric Materials and Platforms: Design Strategies, Performance Enhancement, and Applications in Energy Harvesting and Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.

Flames of Time:

open access: yesScandinavian-Canadian Studies, 2022
The manuscript as narrator in Icelandic children’s novel Bál tímans (2022) belongs to a literary tradition of sentient object narrators who document the domestic spaces in which they circulate. Bál tímans shifts the reader’s focus to normally invisible manuscript owners and users, including women and children, bringing attention to disparities in ...
