Biological cellular structures have inspired many scientific disciplines to design synthetic that can mimic their functions. Here, we closely emulate biological in a rationally designed multicellular hybrid ion pump, composed of hydrogen-bonded [EMIM+][TFSI-] pairs on the surface silica microstructures (artificial mechanoreceptor cells) embedded into thermoplastic polyurethane elastomeric matrix extracellular matrix), fabricate ionic skins. Ionic mechanoreceptors engage hydrogen...
We report a non-trivial facile chemical approach using ionic liquid ([bmim][Cl]) as porogen for the synthesis of (001) faceted TiO2 nanocrystals having mesoscopic void space. This nanomaterial has been doped with Pt nanoclusters through impregnation. The resulting Pt-doped nanomaterials are thoroughly characterized by powder X-ray diffraction (PXRD), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), ultra high resolution transmission (UHR-TEM), energy dispersive...

Soft robotics systems are currently under development using ionic electroactive polymers (i-EAP) as soft actuators for the human-machine interface. However, this endeavor has been impeded by dilemma of reconciling competing demands force and strain in i-EAP actuators. Here, authors present a novel design called "ions-silica percolated dielectric elastomer (i-SPIDER)", which exhibits liquid-confined silica microstructures that effectively resolve chronic issue conventional The i-SPIDER...
Abstract Atomic‐level tailoring of active sites is an efficient strategy for designing high‐performance photocatalysts clean energy. Asymmetric atomic (AAS) like M SA ‐O v ‐M 2 created through hetero‐metal single atoms (M ) doping on defect‐rich metal oxides are favored better activation targeted molecules. However, creating AAS typically demands high energy input, hindering their widespread use in photocatalytic H production. Furthermore, precise control over surface defects to create...
Anatase TiO2 nanocubes and nanoparallelepipeds, with highly reactive {111} facets exposed, were developed for the first time through a modified one pot hydrothermal method, hydrolysis of tetrabutyltitanate in presence oleylamine as morphology-controlling capping-agent using ammonia/hydrofluoric acid stabilizing faceted surfaces. These nanocubes/nanoparallelepipeds characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution (HRTEM) angle annular...
