Additive‐Free Ti3C2Tx MXene Actuator with Large Deformation, Programmability, and High‐Humidity Stability via Precise Interlayer Spacing Control Engineering

open access: yesAdvanced Science, EarlyView.
By sequentially assembling MXene nanosheets with significant size differences, a multistimulus responsive additive‐free MXene actuator with gradient structure is obtained. An innovative cyclic low‐temperature annealing‐rehydration technology is proposed, which achieves precise control of interlayer d‐spacing, initial shape, and actuation behavior of ...

Positive Feedback Organic‐on‐Silicon Upconversion Devices

open access: yesAdvanced Science, EarlyView.
Positive optoelectronic feedback is achieved by depositing a tandem OLED on top of a heterojunction Si photodiode. The resulting hybrid device is bistable and upconverts near‐infrared light (λ = 1050 nm) to visible light (λ = 570 nm) with a photon‐to‐photon upconversion yield of up to 900%.

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

Ultrathin, Unsinkable, Janus‐Faced Solar–Thermal Interfacial Evaporator for High‐Throughput Seawater Distillation and Solar‐Water Production

open access: yesAdvanced Science, EarlyView.
A nanostructured carbon‐coated porous polymeric scaffold is developed to accelerate the hydrological cycle, enabling solar–thermal freshwater production from saline water with reduced energy consumption and CO2 footprint. Abstract Solar–thermal distillation offers immense and hitherto untapped potential for energy‐efficient, sustainable freshwater ...
