Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

Advanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

Advanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

Advanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.
