Rigid Supramolecular Aramid Nanotubes as Catalyst Supports

open access: yesAdvanced Materials, EarlyView.
Molecular nanotube self‐assemblies with high aspect‐ratios and stiffness are demonstrated as nanocatalyst supports. The extended dimensions and tunable surface chemistries of the nanotubes enable tethered gold nanoparticle catalysts to remain dispersed in solution and to be easily recovered through simple filtration.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites

open access: yesAdvanced Materials, EarlyView.
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.
