Abstract:
... To address the difficult challenge of realizing macroscopic supramolecular assembly (MSA) of high-modulus hydrogels, we propose a strategy of introducing a flexible spacing coating to improve the surface compliance for efficient MSA, which holds promise to develop versatile MSA methods for fabricating hydrogel-based tissue scaffolds, and to provide insight into the MSA mechanism. ...

Abstract:
... The VO₂ film with “movable” antireflective (AR) coating was initially designed and successfully prepared to deal with the challenges that VO₂ faced. The “movable” AR layer, including water and other organic solvents, not only endowed VO₂ with active-passive regulation mode but also dramatically enhanced the thermochromic performance. Furthermore, we combined solid and movable antireflection layer ...

Different from previous studies, the wettability gradient is not required to produce lateral motions. Instead, a substrate with two halves decorated with same Cassie area fractions but different length ratios is used and four different motions can be observed b ...

Abstract:
... This paper unprecedentedly reports the effect of metal (nickel) coating on the stress-dependent electric permittivity, piezoelectricity and piezoresistivity of carbon fiber. Both permittivity (2 kHz) and DC conductivity of carbon fiber are increased by nickel coating. For 7-μm diameter carbon fiber, nickel coating (0.25-μm thickness) increases the relative permittivity from 12,200 to 63,200, and d ...

Abstract:
... The definitive role of the intermediate 5,6-dihydroxyindole (DHI) in the formation of polydopamine (PDA) coatings from aqueous dopamine (DA) has not been clearly elucidated and remains highly controversial. Our foray into this debate as reported in this study agrees with some reported assertions that DHI-based coatings are not synonymous with PDA coatings. Our conclusion arises from a systematic c ...
