A Polymer‐Intercalated Modulation Assembly Strategy Towards Mesoporous Single‐Crystalline BiVO4 Materials for Enhanced Photocatalytic Performance

open access: yesAdvanced Science, EarlyView.
A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...

Thermally Programmable Two‐Port Non‐Hermitian Acoustic Metastructure for Broadband and Direction‐Dependent Absorption

open access: yesAdvanced Science, EarlyView.
A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...

The Political Cost of Corruption: Scandals, Campaign Finance, and Reelection in the Brazilian Chamber of Deputies

open access: yesJournal of Politics in Latin America, 2016
While corruption is widely disapproved of, some corrupt politicians continue to win elections. We tackle this paradox by examining the effects of malfeasance scandals in politicians’ behavior.

Modeling and Measurement of Noise in Aluminium Nitride Piezoelectric MEMS

open access: yesAdvanced Electronic Materials, EarlyView.
This work analyzes electrical noise in piezoelectric AlN MEMS devices using a combined measurement‐modeling approach. The framework separates sample and amplifier noise contributions and demonstrates close agreement between model and experiment at both room and cryogenic temperatures.
