Incorporation of nanoscale colloidal objects into three-dimensional (3D) hydrogel networks can not only reinforce the hydrogels as “colloidal cross-linkers”, but also add many extra functionalities for diverse applications. For the first time, def...... -
Marine molluscs have inspired to construct robust composites with hierarchical microstructures, and also to design artificial muscles with rapid and controllable deformation. Abalone nacre has the unique “brick and mortar” structure, whose two-dim...... -
Artificial asymmetric ionic membranes have attracted great interests in harvesting electricity from ubiquitous water activities, while mostly based on delicately-designed nanopores/nanochannels, either to harness saline water in mimic of cytomembr...... -
Porous metallic architectures with well-defined networks possess multiple reactivity center and large specific surface area, offer improved catalytic activity, adsorption capacity, and sensing abilities than bulk materials, thus be an increasingly...... -
Artificial electric skin, which is capable of strongly adhering to different parts of human bodies and precisely detect different types of human motions, shows great promise for biomedical prosthetics, human/machine interfaces, wearable devices an...... -
聚烯烃材料引入长支化结构，能够提升材料熔体强度和异相成核作用，使聚合物具备更加优异的发泡性能，从而扩宽材料的应用领域. 本文利用甲基丙烯酸十八烷基酯（SMA）熔融改性聚丁烯（PB），发现其链段缠结程度提升，发泡行为改善. 通过红外谱图的化学结构分析以及材料的力学性能分析，发现随着SMA添加量的增加，材料拉伸强度降低，冲击强度呈现先升高后降低的趋势. 差示扫描量热（DSC）的分析结果表明改性PB的结晶度下降. 采用间歇釜式法制备PB发泡珠粒，利用扫描电子显微镜（SEM）研究发泡珠粒泡孔结构，...... -
Protein nanostructures in living organisms have attracted intense interests in biology and material science owing to their intriguing abilities to harness ion transportation for matter/signal transduction and bioelectricity generation. Silk nanofi...... -
Liquid metal nanodroplets not only share the similar metallic properties and nanoscale effect with solid metal nanoparticles, but also possess the additional uniqueness in nonvolatile fluidity and ambient sintering ability...... -
Although responsive actuators have been intensively investigated, it remains challenging to enable rapid and self-oscillating actuation under ambient circumstances without human intervention analogous to living organisms. By hybridizing a unique t...... -
The surface modifications of graphene oxide (GO) by biomolecules are widely used to increase the biocompatibility, change the hydrophobicity, solubility and surface properties of GO, and provide GO with selectivity to specific molecules. A simple,......
