Combining artificial cellular compartmentalization and intelligent motion benefits of micro/nanomotors, light is used as energy input to construct an artificial cell-based micromotor capable of photosynthetic anabolism and intelligent directional movement. This system is assembled from phospholipids functionalized with F-ATP synthase and molybdenum disulfide (MoS) nanoparticles (Vesical@MoS-ATPase). The underlying mechanism involves the generation of protons (H) through photo-hydrolysis of MoS nanoparticles within vesicles, which generates a local electroosmotic flow inside the vesicles and drives the negatively charged MoS toward light. The established proton gradient across the phospholipid membrane, in turn, drives the ATP synthase to catalyze ATP production. Both in vitro and in vivo models demonstrate that the micromotor can elevate local intracellular ATP levels upon light and improve the metabolism of denatured chondrocytes. This cell mimicry, with capabilities of migration and biosynthesis, emerges as a promising platform for the next generation of functional bio-interface.

Thermoelectric (TE) materials offer a promising solution to reduce green gas emissions, decrease energy consumption, and improve energy management due to their ability to directly convert heat into electricity and vice versa. Despite their potential, integrating new TE materials into bulk TE devices remains a challenge. To change this paradigm, the preparation of highly efficient tetrahedrite nanocomposites is proposed.

The low-cost hydrothermal method has been successfully applied to synthesize MnS-incorporated MoS nanoflowers (MoS/MnS). The FE-SEM, TEM, XRD, Raman, UV-VIS, and density functional theory (DFT) were used to investigate the surface morphology, structural property, optical property, and simulated optical and dielectric properties. FE-SEM and TEM images reveal the 3D flower-like structure of MoS and the flower-like structure of the nanocomposite.

There is a growing interest in finding alternative materials for food packaging because synthetic plastic materials pose a significant risk to the environment. Chitosan, a natural polymer, is both biodegradable and non-toxic. The present study aimed to prepare composite films made from chitosan, molybdenum disulfide, and zinc oxide (chi-ZnO-MoS).

An ultrafast-responsive α-FeO/Fe(MoO) nanocomposite was developed for the detection of ethanol vapor. The α-FeO/Fe(MoO) nanocomposite was synthesized utilizing a green, normal-pressure, microwave-assisted method followed by an in situ solid-state reaction process with flower-like MoS as a unique precursor. The resulting α-FeO/Fe(MoO) composite presents a porous, agminated petal-like structure with α-FeO nanoparticles homogeneously attached to the surfaces of Fe(MoO) nanosheets.
