In order to study the droplet formation mechanism, the structure of the ribbon is investigated. As the ribbon is etched by cyclohexane (the selective solvent of PS), we find that PS distributes in the middle of the ribbon and PMMA distributes on the three phase contact line (see ...
self-poled and bio-waste based piezoelectric material. Pomelo fruit membrane is composed of cellulose 1, hemicellulose and pectin-based polysaccharides. Generally, cellulose is a bio-polymer consist of β-1,4-glycosidic bonds which are present in every repeating unit ofd-glucose21. Hemicellulose and...
chirality perception in natural supramolecular systems such as enzymes, proteins, and DNA arousing biomimetic studies on artificial supramolecular chiral sensing30. However, achieving macroscopic helical self-motion in stimuli-responsive material is still a challenge31. Thus integrating chirality perception wit...
Furthermore, typical and new applications focused on smart home, gas sensing, human monitoring, robotics, transportation, blue energy, aircraft, and aerospace, are discussed to provide an overall prospect of smart cities. 2. Self-Powered Sensors and Wearable Solutions Currently, the human body can...
