Ying Wang, Yingying Fang, Yongguang Yin. Unveiling a “New” Species Mercurous Mercury: Assessing the Environmental Stability and Its Implications[J]. Progress in Chemistry, 2025, 37(3): 293-294.
Mercury (Hg) is a global pollutant. The redox transformation of Hg plays a pivotal role in the Hg global cycle, with mercurous mercury (Hg(I)) serving as an important intermediate theoretically. Due to the metastable nature of Hg(I), it was considered unstable and susceptible to dispropor-tionation. This finding not only challenged the traditional viewpoint that Hg(I) cannot exist in wa-ter, but also revealed that the stability of Hg(I) had a significant effect on the reduction process of Hg(II) in the natural water.

Nowadays stretchable electronic devices have become a hot research topic in the field of information electronics because of their excellent mechanical and electrical properties. As the high-speed electron transmission channel in stretching electronic devices, stretchable conductive materials play a crucial role in realizing the functions of stretching electronic devices. Liquid metal has become a hot research object in the field of stretchable conductive composites in recent years because of its intrinsic flexibility and excellent conductivity. Liquid metal is a room temperature liquid conductive material, which exhibits excellent stretchability and tunability due to its inherent high conductivity, fluidity, and ductility. Liquid metal-based stretchable conductive composites preparation and patterning techniques have been reported and many stretchable devices with excellent combination of mechanical and electrical properties have been prepared. In view of the general structural characteristics of liquid metal-based stretchable composites, the key to the preparation is how to solve the interfacial non-impregnation problem caused by the physical property differences between different materials. Therefore, starting from the common types of composites, this paper firstly briefly introduces the components and physical properties of liquid metals generally used, as well as the stretchable polymer matrix materials usually employed. Then, the composite methods of conductive materials and elastomer materials in liquid metal-based electrodes are reviewed from the two ways of "passive" and "active" to deal with the problem of non-wetting at the interface, as well as the blending and dispersion method and the new modification method. Finally, the latest research progress is introduced, and the current status of liquid metal research is summarized. Future development and potential problems to be faced are also discussed.

As an important family of synthetic polymers, poly(meth)acrylates have a wide range of applications in the fields of coatings, adhesives, biomedines, electronic and electrical materials. However, the (meth)acrylates monomers are mainly derived from petrochemical resources.Transformations of biomass into (meth)acrylate monomers and polymers have attracted growing research interest from the viewpoint of sustainability.

Black carbon (BC) particulate matter has significant light-absorbing capacity and is an important species contributing to haze pollution and global warming. However, quantitative studies of the light absorption capacity of black carbon (BC) have long been unable to reach a consensus affecting the accurate assessment of its environmental and climate effect. The morphological evolution of BC particles is the important factor affecting the light-absorbing capacity. However, the current literature review lacks a comprehensive summary of the characteristics and mechanisms involved in the evolution of BC micromorphology. This review summarizes the relevant studies on BC morphology evolution in recent years including the quantitative parameters of BC morphology, measurement and calculation methods of morphology parameters, the micromorphology evolution characteristics of BC during condensation process, phase separation process, coagulation process and evaporation process, and its evolution mechanism and main influencing factors. The evolution of the microphysical morphology of BC particles during different aging processes is the key to explaining the controversy over the light absorption of BC particles. However, there are still many uncertainties in the morphology evolution of BC core and the quantitative assessment of light absorption of complex-structured BC particles in these processes. Therefore, tracking the actual atmospheric BC morphology evolution, further investigating the effect of morphology evolution mechanism on the BC core collapse, and improving the models of BC light absorption and radiation will be the key research direction in the future.

Solar photoelectrochemical (PEC) water splitting holds significant importance for the development of sustainable green energy. With ongoing research, the BiVO4 photoanode, a core component of PEC systems, faces challenges in scaling up and maintaining long-term stability.
