The development of eutectic Ga–In alloy liquid-metal nanoparticles (EGaIn LM NPs) represents a significant advancement in the field materials science because their low melting points and desirable properties, including thermal electrical conductivity, conformability, biocompatibility. However, traditional technique for synthesizing EGaIn NPs via ultrasonication aqueous media results notable surface oxidation, which can degrade such as stability, size uniformity, flexibility, consequently, restrict potential uses. This paper presents novel method carbonated water to reduce oxidation. Smaller that exhibited notably lower oxide formation were generated without stabilizing polymers or surfactant chemicals, even water-based surroundings. Moreover, oxidation inhibition mechanisms ions scavengers •OH radicals during revealed, highlighting promising applications media.

Hydride (H–) species on oxides have been extensively studied over the past few decades because of their critical role in various catalytic processes. Their syntheses require high temperatures and presence hydrogen, which involves complex equipment, energy costs, strict safety protocols. tend to decompose atmospheric oxygen water, reduces activities. These challenges highlight need for further research improve stability efficiency processes develop safer cost-effective synthesis methods. This paper introduces an ultrasonic fabrication method gallium hydride liquid metal (LM) nanoparticles (Ga–H@LM NPs) water describes evaluation properties. The Ga–H@LM NPs were synthesized by dispersing metals eutectic gallium–indium using a two-step ultrasonication process ice bath. Ga–H was confirmed Fourier-transform infrared spectroscopy. demonstrated rapid hydrogenation 4-nitrophenol reductive degradation azo dyes within minutes without external reducing agents like NaBH4. proposed mechanism high-energy cavitation at interface between LM promotes formation H2 from its activation form particles surface during ultrasonication. study has significant implications advancing field catalysis it provides novel efficient stable oxides.

Nanodroplets of Gallium‐Based Liquid Metal (LM) have applications in stretchable electronics, electrochemical sensors, energy storage, hyperthermia, and rapid polymerization. The gallium oxide layer around LMNDs prevents aggregation. However, LM nanodroplets (LMNDs) are neither mechanically nor chemically stable. ultrathin ruptures under slight pressure, hindering their use electronics. shell also dissolves slightly acidic/alkaline solutions, making them unstable for storage sensing. We demonstrate the synthesis a dry powder with an core reduced graphene shell. Graphene provides excellent mechanical chemical stability permits electrical conductivity. Its porous structure does not block ion exchange between droplets environment, allowing to be used resulting EGaIn powders benefit from higher surface long‐term stability, addressing LMND limitations. report using GO@EGaIn nanocomposite as anode alkali‐ion batteries novel Ag‐EGaIn cell impressive capacity. combination liquid deformability LMNDs, area nano form, expands metals electronics storage.
