Tuning Excitonic Properties and Charge Carrier Dynamics by Halide Alloying in Cs3Bi2(Br1−xIx)9 Semiconductors

Advanced Optical Materials, EarlyView.
This work studies the effect of halide alloying in Cs3Bi2(Br1−xIx)9 (0 ≤ x ≤ 1) semiconductors. The x = 0.6 shows the smallest bandgap, lowest exciton binding energy, and longest charge carrier lifetimes, showing promising properties for optoelectronic and photocatalytic applications.

Cyclodextrin‐Functionalized Light‐Driven Cu2O Micromotors for Simultaneous Capture and Degradation of Bisphenol A

Advanced Robotics Research, EarlyView.
Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.
