Highly Scalable, Raspberry‐Like Microbeads with Nano‐/Micro‐Confined Hybrid Hydrogel Desiccants for Rapid Atmospheric Water Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
A scalable nano‐/micro‐confinement strategy is developed, where polyacrylamide (PAM)‐LiCl hybrid desiccants are confined within hollow nanoparticles (HNPs) and assembled into raspberry‐like microbeads. The beads have a hydrogel‐rich core and an NP‐rich shell for fast absorption and desorption, releasing water 13.6 L kg⁻¹ day⁻¹.

High‐Performance Field‐Effect Transistors and Phototransistors Array Based on Solution‐Processed Quasi‐1D Van der Waals Ta2Pd3S8 Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Herein, the synthesis of Ta₂Pd₃S₈ nanowires is reported via scalable liquid cascade exfoliation and their integration into high‐mobility field‐effect transistors (FETs) and sensitive photodetectors, achieving carrier mobility of up to 27.3 cm2 V⁻¹ s⁻¹ and responsivities of 322.40 A W⁻¹ and 1.85 mA W⁻¹ for single nanowire and network devices ...

Numerical investigation of boiling [PDF]

open access: yes, 2012
In this work, we study different phenomena that occur during nucleate boiling. We numerically investigate boiling using two phase flow direct numerical simulation based on a level set / Ghost Fluid method.

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

open access: yesAdvanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...
