Abstract MXene and graphene cryogels have demonstrated excellent electromagnetic interference (EMI) shielding effectiveness due to their exceptional electrical conductivity, low density, ability dissipate waves through numerous internal interfaces. However, synthesis demands costly reduction techniques and/or pre‐processing methods such as freeze‐casting achieve high EMI mechanical performance. Furthermore, limited research has been conducted on optimizing the cryogel microstructures...
Janus structures have unique properties due to their distinct functionalities on opposing faces, but yet be realized with flowing liquids. We demonstrate such liquids a customizable distribution of nanoparticles (NPs) throughout by joining two aqueous streams NP dispersions in an apolar liquid. Using this anisotropic integration platform, different magnetic, conductive, or non-responsive NPs can spatially confined opposite sides the original interface using magnetic graphene oxide (mGO)/GO,...

LS demonstrated general method design multifunctional specific hierarchical order morphology, conveniently controlled by...

Drop motion and deformation of a conducting drop in perfect (or leaky) dielectric fluid leaky fluid, non-uniform electric field is presented. The investigated electrode configuration the pin-plate type. Systematic experiments comparison with existing analytical models carried out. main results are summarized as follows: (i) dielectrophoretic explained reasonably well assuming spherical drop, although deviations observed at large deformations. Thus shows weak shape dependence. (ii) has...
Interfacial assemblies formed by colloidal complexation are effective in multiphase stabilization, as shown structured liquids and Pickering emulgels. Herein, we demonstrate a type of biobased system that spontaneously stabilizes an organic phase continuous hydrogel phase. Specifically, triterpene extracted from bark (betulin, BE) is added to containing coniferous resin (rosin acid, diterpene). BE take part strong noncovalent interactions with the nanochitin dispersed aqueous (hydrogel)...
This study coined a practical strategy entitled “Aerogel Electromagnetic Traps” toward blocking the scattered electromagnetic waves from metallic substrates through aerogel engineering, leading to absorption dominant shielding constructs.
We have developed bioparticle-based hybrid superhydrophobic-hydrophilic coatings that significantly enhance water collection in fog harvesting. Our use of superhydrophobic betulin crystals, extracted from birch bark, to create microtextured represents...
Synthetic adhesives commonly used in shipbuilding, plumbing, and various industrial household applications pose environmental health concerns due to chemical leaching other issues. In this work, we present a sustainable alternative using chitin nanofibers (ChNF) enhance the networking surface binding of biomolecules. We investigate aqueous-based formulations composed tannic acid (TA), poly(vinyl alcohol) (PVA), nanofibers, which form robust adhesive complexes. These are driven by multiple...
The significance of synthetic foams as insulative materials stems from their mechanical and water resistance well cost-effectiveness. Broadly, the design building envelopes should also consider fire mold impacts on environment (end life compostability). This study addresses these issues considering ever-increasing demand for sustainable sources to develop highly porous materials. We introduce a versatile strategy based wet-foam laying cellulosic fibers that leads hierarchical structures...
Here, we describe the all-aqueous bicontinuous emulsions with cholesteric liquid crystal domains through hierarchical colloidal self-assembly of nanoparticles. This is achieved by homogenization a rod-like cellulose nanocrystal (CNC) two immiscible, phase separating polyethylene glycol (PEG) and dextran polymer solutions. The dispersed CNCs exhibit unequal affinity for binary mixtures that depends on balance osmotic chemical potential between phases. Once at critical concentration, CNC...
We study the influence of a megahertz Rayleigh surface acoustic wave (SAW), propagating in solid substrate, on pattern deposition solute mass off an evaporating solution. An experimental procedure, where film solution undergoes controlled evaporation chamber, shows that SAW alters state deposition. Increasing power supports increase density deposited patterns. Beyond threshold conditions, patterns merge and we observe film. A simplified theory suggests deforms geometry film, which is...
