Diatom-Inspired 3D Hierarchical Liquid Metal Sponge for Flexible Photoelectrochemical Photodetectors.

Inspired by the hierarchical micro/nanoscale architecture of diatoms which are renown for capturing and utilizing dim light in oceanic environments, a three-dimensional (3D) hierarchical liquid metal (LM) sponge was proposed for advancing flexible photoelectrochemical (PEC) photodetectors. A room-temperature LM nanodroplet (ND)-bridging strategy by deformable welding LM NDs on polymer fibers was developed to controllably fabricate 3D architectures consisting of LM integrations in the form of interconnected either one-dimensional (1D) liquid-bridges or two-dimensional (2D) liquid-films. Optical characterization reveals that the 3D hierarchical architecture with radian 2D liquid-films (3D-HA-R2DLF) exhibits moderate absorption (0.

Tailoring Heterostructure Growth on Liquid Metal Nanodroplets through Interface Engineering.

Liquid metal (LM) nanodroplets possess intriguing surface properties, thus offering promising potential in chemical synthesis, catalysis, and biomedicine. However, the reaction kinetics and product growth at the surface of LM nanodroplets are significantly influenced by the interface involved, which has not been thoroughly explored and understood. Here, we propose an interface engineering strategy, taking a spontaneous galvanic reaction between Ga and AuCl ions as a representative example, to successfully modulate the growth of heterostructures on the surface of Ga-based LM nanodroplets by establishing a dielectric interface with a controllable thickness between LM and reactive surroundings.

Synthesis and Application of Liquid Metal Based-2D Nanomaterials: A Perspective View for Sustainable Energy.

With the continuous exploration of low-dimensional nanomaterials, two dimensional metal oxides (2DMOs) has been received great interest. However, their further development is limited by the high cost in the preparation process and the unstable states caused by the polarization of surface chemical bonds. Recently, obtaining mental oxides via liquid metals have been considered a surprising method for obtaining 2DMOs.

A hydrothermally synthesized MoSSe alloy with deep-shallow level conversion for enhanced performance of photodetectors.

Photoelectric detectors based on binary transition metal chalcogenides have attracted widespread attention in recent years. However, due to the high-temperature synthesis of binary TMD, high-density deep-level defect states may be generated, leading to poor responsiveness or a long response time. Besides, the addition of an alloy will change the DLDSs from deep to shallow energy levels caused by S vacancies.
