Ruddlesden–Popper Defects Act as a Free Surface: Role in Formation and Photophysical Properties of CsPbI3

open access: yesAdvanced Materials, EarlyView.
This work investigates Ruddlesden–Popper (RP) defects in vapor‐deposited CsPbI3 thin films using electron microscopy, density functional theory, and optoelectronic measurements. The atomic positions at the planar defect are found comparable to those of a free surface, revealing their role in phase stabilization.

Electrospun Lignin/ZnO Nanofibrous Membranes for Self‐Powered Ultrasensitive Flexible Airflow Sensor and Wearable Device

open access: yesAdvanced Materials, EarlyView.
This study explores the novel sensing applications of water evaporation‐induced power generation, by using lignin/ZnO nanofibrous membranes for sensing airflow through output voltage variation. Obtained lignin/ZnO airflow sensors are self‐powered, precise, and quick‐responding, and can be used as wearable devices for breath monitor, surrounding ...

Ultrafast Light‐Driven Electronic and Structural Changes in LaFeO3 Perovskites Probed by Femtosecond X‐Ray Absorption Spectroscopy

open access: yesAdvanced Materials, EarlyView.
Femtosecond X‐ray absorption spectroscopy (fs‐XAS) at PAL‐XFEL captures ultrafast electronic and structural dynamics in epitaxial LaFeO3 thin films. Combined with DFT and multiplet calculations, the study reveals photoinduced ligand‐to‐metal charge transfer, followed by polaron formation and reduced oxygen 2p‐iron 3d hybridization, explaining key ...

Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

open access: yesAdvanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

Pairing N‐Vacancy and Adjacent Ni‐Sites in the Local Microenvironment to Regulate the Urea Oxidation Reaction Pathway With Enhanced Kinetics

open access: yesAdvanced Materials, EarlyView.
In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...
