Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

Advanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Electroadhesion Suction Cups

Advanced Materials, EarlyView.
Electroadhesion (EA) Suction Cups are electrically operated soft grippers that can pick up a wide range of objects from the top. A soft membrane, driven by electrostatic forces, conforms to surfaces, creating a passive vacuum when lifted. EA suction cups eliminate bulky vacuum systems, offering a compact, efficient, and portable alternative for ...

Dual‐Scale Hydration‐Induced Electrical and Mechanical Torsional Energy Harvesting in Heterophilically Designed CNT Yarns

Advanced Materials, EarlyView.
Despite the abundance and vast energy potential of water, its efficient utilization is hindered by single‐mode energy conversion. Herein, heterophilic CNT yarns that allow for simultaneous energy harvesting by means of dual‐scale hydration—electrical energy harvesting through proton gradients and mechanical torsional harvesting through microchannel ...

Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO

Advanced Materials, EarlyView.
A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.
