“…34 In the following, we propose a synthetic procedure where the mercury thiolate is prepared in situ from liquid mercury. We sonicate liquid Hg in DDT for several hours 35 and then obtain a mixture of mercury thiolate crystals and colloidal liquid Hg, 36 see Figure 2a and b and Figure S7.…”

HgTe nanocrystals are currently the most promising colloidal material for infrared detection, combining broadly tunable infrared absorption and photoconductive properties. Current synthesis leads to a limited amount of material and relies on a highly toxic water-soluble form of Hg. Here, we explore the possibility of using Hg thiolate as Hg source and demonstrate that the latter can be formed in situ from liquid Hg. The developed protocol allows large masses (7 g) and highly concentrated (100 g/L) synthesis, which is a step forward for the transfer of this material towards industry. The transport properties of the material have also been investigated and we observe a transition from p to n-type with size. We observe that the threshold of the p to n switch depends on the growth method which enables for a given size of nanocrystal the formation of p-n junction. This work has great potential to design infrared sensor with optimized charge dissociation.

“…It has been demonstrated that sonication of bulk liquid metal droplets can produce micro‐, meso‐, and nanosized liquid metal spheres. Previous reports show that thiol‐stabilized mercury and EGaIn (75 wt% Ga, 25 wt% In) liquid metal droplets with dimensions in the order of micro‐ to nanometer can be successfully synthesized through sonication …”

[12][13][14][15][16] They have also been used for a variety of sensing applications including chemical and biochemical sensors. [17][18][19][20][21] In principle, solid metals can be replaced by liquid metals to form "liquid metal"/"metal oxides" (LM/MO) structures. Interestingly, despite their immense potentials, LM/MO structures have rarely been reported. [ 22 ] Furthermore, none of these works take advantage of the nature of the incorporated liquid metals. In addition to the well-known benefi ts that solid metals can offer, liquid metals add extra dimensions to the structures, which originate from their soft and liquid nature. This brings fl exibility, the possibility of amalgamation with other metals and their recoverability, mobility and high conformation to the system.We have previously shown the possibility of coating relatively large liquid metal droplets of galinstan using metal oxide nanoparticles. [23][24][25] By doing this, we created liquid metal marbles with extraordinary physical and chemical properties. Our investigations associated these properties to the interfaces between liquid metal and metal oxide nanoparticles in combination with the fl exibility of the marbles, thereby providing extra degrees of freedom in order to manipulate their functionalities on demand. However, the properties of large liquid metal marbles are strongly surface dependent and the bulk of the droplet is mostly redundant. For using the bulk of liquid metals, it should be divided into the smallest possible stable entities.It has been demonstrated that sonication of bulk liquid metal droplets can produce micro-, meso-, and nanosized liquid metal spheres. Previous reports show that thiol-stabilized mercury and EGaIn (75 wt% Ga, 25 wt% In) liquid metal droplets with dimensions in the order of micro-to nanometer can be successfully synthesized through sonication. [ 26,27 ] In this work, we utilize micro-to nanosized galinstan spheres with coated metal oxide nanoparticles to form the LM/ MO spherical structures suspended in aqueous solutions. Galinstan (68.5 wt% Ga, 21.5 wt% In, and 10 wt% Sn) is chosen as it poses less health hazards in comparison to liquid metals such as mercury. The surface metal oxide nanoparticles are either inherently formed during the synthesis process or coated onto the surface of galinstan spheres. We fully characterize the LM/MO spherical structures in terms of stoichiometry and optical properties, including the demonstration of plasmon A new platform described as the liquid metal/metal oxide (LM/MO) framework is introduced. The constituent spherical structures of these frameworks are made of micro-to nanosized liquid metal spheres and nanosized metal oxides, combining the advantages of both materials. It is shown that the diameters of the spheres and the stoichiometry of the structures can be actively controlled. Additionally, the liquid suspension of these sphere...

“…Main difficulties related to the usage of mercury are the reduction of Hg-containing residues release into the environment and the elimination of Hg-contamination [1,2,4]. Mercury can be readily bound by incorporating it within plate-like crystals of Hg(S-R) 2 [5]. Several other organic molecular systems have also been recently designed, which are capable of efficiently localizing mercury for subsequent disposal [6][7][8].…”

Surface tension of liquid mercury: a comparison of density-dependent and density-independent force fields

2015

View full text Add to dashboard Cite

Motivated by an experimental interest we investigate by the means of atomistic Molecular Dynamics simulation the ability of density-independent, empiric density-dependent, and recently proposed embedded-atom force fields for liquid mercury to predict the surface tension of the free surface of liquid mercury at the temperature of 293 K. The effect of the density dependence of the studied models on the liquid-vapor coexistence and surface tension is discussed in detail. In view of computational efficiency of the density-independent model we optimize its functional form to obtain higher surface tension values in order to improve agreement with experiment. The results are also corroborated by Monte Carlo simulations and semi-analytic estimations of the liquid-vapor coexistence density. *
