Steric‐Pressure‐Driven Topological Reconstruction for High‐Performance Zintl Phase Thermoelectrics with Machine‐Learning Validation

open access: yesAdvanced Science, EarlyView.
Synergistic Sr and Ag co‐doping drives steric‐pressure‐induced reconstruction from a 2D layered structure to a cross‐linked 3D framework in the Ca9‐xSrxZn4+y‐zAgzSb9 system, enhancing carrier mobility while maintaining a large Seebeck coefficient and doubling ZT to 0.73 at 873 K, with hybrid transfer machine learning further capturing the compositional

Contact‐Free Human‐Machine Interfaces via Printed Thermopile Infrared Arrays

open access: yesAdvanced Science, EarlyView.
Can a printed sheet locate and sense a fingertip without being touched? Fully printed, flexible thermoelectric arrays convert the infrared from a hovering finger directly into voltage, with no external power. Aerosol‐jet‐printed silver mirrors partially shield each pixel, creating a local temperature gradient.

Nonstoichiometric Defect Engineering in Mn2+‐Doped MgGa2O4 Persistent Phosphors Toward Enhanced Luminescence and Multimodal Optical Manometry

open access: yesAdvanced Science, EarlyView.
Mg2+ deficiency transforms Mn2+‐doped MgGa2O4 into a multifunctional persistent phosphor, enhancing green emission, thermal stability, and afterglow effect for optical anti‐counterfeiting. Under compression, spectral shifts enable visual pressure sensing with a sensitivity of 5.01 nm GPa−1 over a pressure range up to 30 GPa.
