We report a wrinkled configuration for MOF thin films. The deformable structures confer enhanced strain tolerance, and the wrinkles provide additional exposed surfaces compared with that of planar configurations. Unlike common methods to produce wrinkled structures in other inorganic materials, we developed a synthesis protocol that uses diffusion-driven instability to generate wrinkled MOF thin films that could be utilized for gas seperation and electronics with flexible MOF films.

This study demonstrates that a dynamic hydrogel composite can release cellular-size granules in the physiological environments for regenerative medicine and bioelectronics, which has been long sought in the development of hydrogel-based artificial cells21. A monolithic-to-focal evolving process allows the composite to harness the properties and functions of both monolithic and focal biointerfaces. The hydrogel composites use gelatin and chitosan as the hydrogel matrix to respond to biological environments while also facilitating macroscopic material shaping and manipulation.

We designed a soil-inspired chemical system that consists of nanostructured minerals, starch granules and liquid metals. The soil-inspired material possesses chemical, optical and mechanical responsiveness to yield write–erase functions in electrical performance. The composite can also modulate bacterial growth both in vitro and in vivo, such as enriches gut bacteria diversity, rectifies tetracycline-induced gut microbiome dysbiosis and ameliorates dextran sulfate sodium-induced rodent colitis symptoms within rodent models.

In this work, we show that the periplasm, an underappreciated subcellular region in materials research, can offer a nongenetic pathway for biomineralization of metastable semiconductor nanoclusters. Under light stimulation, the metastable semiconductor nanoclusters could couple with the electron transport chain to increase ATP levels and enhance malate production in the living hybrids. Using the E. coli strain as a model, the current system to develop periplasmic biointerface for enhanced solar-to-chemical production might be extended to other bacterial cells to potentially endow additional sustainability level to the bioremediation applications

We developed a cost-competitive and environmentally friendly approach that is promising for sustainable and scalable production of semiconductor biohybrids towards solar-driven chemical production utilizing multiple pollutants in wastewater. Compared with fossil-fuels refining and sugar-based bacterial fermentation, the wastewater-derived biohybrid system shows lower carbon emission and production cost. We believe wastewater-based hybrid fermentation will provide an alternative for both sustainable biomanufacturing and environmental remediation.

In this work, we showed that a porosity-based heterojunction, a largely overlooked system in materials science, can yield an efficient photoelectrochemical response from the semiconductor surface.

In this work, we identified several soft- hard composite designs in naturally occurring systems, and we use these designs to categorize the existing bioelectric interfaces and to suggest future opportunities in bioelectric studies.

In this review, we systematically summarize the attributes, fabrication methods, and applications of gallium-based liquid metal particles. Existing challenges and future opportunities regarding liquid metal particles are discussed herein.

We designed a liquid metal based composite that can change from non-conductive states to fully conductive states with mechanical pressure. Therefore, we can simply use a pen to create arbitrary conductive circuits on a soft substrate.

We presented a completely soft, stretchable silicone composite doped with thermochromic pigments and innervated with liquid metal. The ability to deform the liquid metal couples geometric changes to Joule heating, thus enabling tunable thermo-mechanochromic sensing of touch and strain.

We developed a super facile way to pattern liquid metal into complicated microstructures with branches and dead-ends. The process only took less than 1 minute.

We described here a light-fueled liquid-metal transformer for effective endosomal escape-facilitated cargo delivery via a chemical-mechanical process. Such liquid metal transformer could absorb and convert photoenergy to drive the simultaneous phase separation and morphological transformation from nanospheres to hollow nanorods to promote endosomal escape of payloads.
