Directional transportation of objects ( liquids and solids ) has crucial applications from energy transfer , intelligent robots to biomedical devices , which has become a frontier for research .Realizing directional solid transportation under a confined pressure environment requires a strong mechanical driving force to overcome the rising interf...
Deep eutectic solvents ( DESs ) are an emerging class of solvents usually formed by hydrogen bond donors ( HBDs ) and hydrogen bond acceptors ( HBAs ) at a fixed molar ratio .Based on the above principle , the researchers synthesized Cu2 ( OH ) 3NO3 nanosheets at room temperature by adding Cu ( NO3 ) 2 to these DESs . The material shows oxidase-...
Stimuli-responsive hydrogels not only express excellent biocompatibility , but also can respond when exposed to external stimulation , enabling a wider range of applications in biomedicine .The soaking strategy adopted was able to not only achieve step-wise volume contraction of the sodium alginate structure , but also continuous enhancement of ...
As a newcomer in the alloy material world , high entropy alloys exceed the traditional alloy design concept as they possess more than 5 elements with a molar ratio of 5 ~ 35% .Has successfully prepared a series of high entropy alloy-based high temperature solar selective absorbing coatings through component modulation , conformational entropy op...
Ice-skating is a particularly popular sport , and it is widely believed that ice - skating is possible due to the formation of an intermediate layer of liquid water that forms between a layer of solid ice and the icy surface , which lubricates the skates .In addition , the solid-liquid lubrication and self-healing effect are realized by relying ...
