Abstract Liquid metal nanodroplets are an emerging class of underexplored materials with significant potential in many applications, including catalysis, bio‐therapeutics, and phase‐change materials. These nanostructures generally synthesized by mechanical agitation via ultrasonication low‐melting metals like Ga. Once these successfully synthesized, they can be suspended a vast array different solvents. However, one major issue arises specifically liquid alloys which found to de‐alloy the...
An electrocatalyst with trace vanadium alloyed liquid metal reduces CO 2 directly into solid carbon.
The exceptional properties of liquid metals at room temperature, such as their fluidity, stretchability, deformability, and potential applications, have rapidly inspired the scientific community. At present, main challenge is overcoming technical barriers associated with characterization metal systems, which resulted in molecular structure remaining effectively unknown. This lack knowledge has significantly hampered progress emerging field chemistry, prohibiting tailored design relegating...
Abstract Crystallization of alloys from a molten state is fundamental process underpinning metallurgy. Here the direct imaging an intermetallic precipitation reaction at equilibrium in liquid‐metal environment demonstrated. It shown that outer layers solidified are surprisingly unstable to depths several nanometers, fluctuating between crystalline and liquid state.

The rise of antibiotic resistance in pathogenic bacteria requires new therapeutics to be developed. Several metallic nanoparticles such as those made from silver, copper, and zinc have shown significant antibacterial activity, part due metal ion leaching. Ga3+ containing compounds also been properties. Accordingly, it is estimated that Ga droplets may antibacterial, some studies date confirmed this. Here, multiple concentrations were tested against the resistant Gram-positive...
Abstract Liquid metals (LMs) are emerging as unique fluids for a variety of applications, but their nanoscale solvation properties remain largely understudied.
