Electronic skins are developed for applications such as biomedical sensors, robotic prosthetics, and human–machine interactions, which raise the interest in composite materials that possess both flexibility sensing properties. Polypyrrole-coated cellulose nanocrystals nanofibers were prepared using iron(III) chloride (FeCl3) oxidant, used to reinforce polyvinyl alcohol (PVA). The combination of weak H-bonds iron coordination bonds synergistic effect these components yielded self-healing...
Abstract Superwettable surfaces show great potential in water harvesting applications, however, a scalable surface remains elusive due to the trade‐off between deposition and transport. Herein, we report unique superhydrophobic with tunable nanoscale hydrophilicity constructed by structured Pickering emulsions. Preferential exposure of cellulose nanocrystal's outer wax microspheres accelerates droplet allowing for manipulation mobility. Appropriate tuning wetting characteristics surfaces,...
A surfactant is an efficient and common additive used to enhance the spreading of droplets on hydrophobic surfaces. However, a high concentration required achieve desired performance, resulting in environmental pollution increased costs. Additionally, pesticide loading capacity surfactants at low concentrations (below their critical micelle concentrations) concern. Thus, this study, we developed strategy droplet deposition by mixing small amounts sodium dodecyl sulfate (SDS) (0.1 wt %)...
Cellulose nanocrystals (CNC) have received much attention as a drug delivery agent, but their hydrophilic nature hinders hydrophobic loading. Ionotropic gelation using CNC and chitosan (CS) can enhance the loading/encapsulation efficiency of compounds, improve colloidal stability, strengthen mucoadhesion due to cationic surface CS. The behavior CNC/CS nanocomposites loaded with emamectin benzoate (EMB) were elucidated by measuring particle size, zeta potential, contact angle, morphological...

Smart surfaces with superhydrophobic/superhydrophilic characteristics can be controlled by external stimuli, such as temperature. These transitions are attributed to the molecular-level conformation of grafted polymer chains due varied interactions at interface. Here, tunable were prepared grafting two well-known thermo-responsive polymers, poly(N-isopropylacrylamide) (PNIPAM) and poly(oligoethylene glycol)methyl ether acrylate (POEGMA188) onto micro-pollen particles uniform morphology...
Electric-field-induced phase transitions and piezoelectric properties of <001>-oriented Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>-32%PbTiO<sub>3</sub> (PMN-PT) single crystals have been investigated as a function temperature. It was found that the for PMN-PT are strongly dependent on The measurements polarization longitudinal strain unipolar electric field show induced monoclinic-tetragonal transition decreases linearly with temperature in range between 23 °C 75 °C.

Nanofluidic channel constructed using two-dimensional material (2D) is a promising system for harvesting osmotic energy from nature. Current systems stacks of 2D nanosheets possess high ion selectivity but they suffer poor mechanical strength and flux. The intercalation nanofibers, such as silk nanofiber, Kevlar nanofiber cellulose into membrane can enhance the structural stability provide additional space charge to maintain density, while entanglement agglomeration micro-scale polymer chain...
