Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.

Operando Temperature Sensing at the Actual Electrocatalytic Interface by Nanodiamond Quantum Sensors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating a wide‐field microscope with a custom‐designed electrolyzer, nanoscale temperature changes can be recorded in situ during the electrolysis process without interfering with ongoing electrochemical reactions. This method establishes a correlation between the interface temperature and specific electrochemical reactions, making the measured ...

A stigmergy-based analysis of city hotspots to discover trends and anomalies in urban transportation usage

open access: yes, 2018
A key aspect of a sustainable urban transportation system is the effectiveness of transportation policies. To be effective, a policy has to consider a broad range of elements, such as pollution emission, traffic flow, and human mobility.

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

open access: yesAdvanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...
