Summary: A liquid Sn cathode is used to fabricate core-shell Sn-C spheres for CO2 electroreduction, achieving a CO2-fixation current efficiency higher than 84% and a high reversible lithium-storage capacity. This strategy is also applicable to other low melting point metals and enables energy-efficient CO2 conversion and value-added metal-carbon materials fabrication, leading to an overall carbon-neutral electrochemical reduction of CO2.

Summary: High-purity and fine CrB powders were synthesized in (Na, K)Cl molten salt at 850 degrees C for 2 h, and then used as precursors to synthesize homogeneous and size-controlled Cr2AlB2 powders at 900 degrees C for 2 h. The formation mechanisms involve in-situ reaction of Cr atom with B powders for CrB, and mutual migration of Al and CrB followed by Al intercalation for Cr2AlB2.

Summary: Researchers have developed a low-cost concrete-based thermal energy storage tank that can operate at high temperatures and in corrosive environments. The engineered concrete composites are made using commercially available additives and coatings. Rigorous testing has shown that the tanks can effectively withstand thermal shocks experienced during daily salt charge/discharge cycles. Additionally, the salt diffusion through the porous concrete walls is suppressed by using external coatings. The compatibility of the engineered composites with high-temperature chloride salts has also been qualitatively evaluated under a high-flux solar simulator.

Summary: This study investigates a method of molten salt dealloying using real-time in situ synchrotron three-dimensional X-ray nano-tomography, revealing long-range diffusion as the rate-determining step for the process. It also shows that subsequent coarsening is primarily surface diffusion controlled, with Rayleigh instability leading to ligament pinch-off and isolated bubbles in ligaments. X-ray absorption near edge structure spectroscopic images characterize the chemical environments and demonstrate that molten salt dealloying prevents surface oxidation of the metal.

Summary: Electrohydrodynamic redox 3D printing (EHD-RP) is an additive manufacturing technique that enables on-the-fly chemistry switching during deposition, with submicron resolution and multi-metal capabilities. By using aqueous solvents instead of organic solvents, the materials palette for EHD-RP can be expanded, allowing reproducible deposition of metals such as Cu and Zn. Additionally, the deposited Zn structures can be partially transformed into semiconducting ZnO structures through oxidation.

Summary: Molten salt electrorefining is a powerful technology for upcycling titanium scrap due to its ability to remove impurities. However, achieving stable operation is still a challenge for industrial applications, particularly in terms of the anode and cathode current efficiency. This study investigates the anodic dissolution and cathodic deposition processes of titanium under high-temperature operational conditions using a direct three-dimensional visualization method. The results show that the current efficiency is affected by the concentration of titanium ions in the melt.

Summary: MXenes are two-dimensional transition metal carbides and/or nitrides with unique physiochemical properties that have attracted extensive interest in various fields. However, current synthesis methods face limitations such as hazardous conditions, high costs, and difficulties in large-scale production. Therefore, the development of a general, safe, cost-effective, and scalable synthesis method for MXenes is crucial. In this study, a fast synthesis method called molten salt-shielded synthesis (MS3) was reported, which successfully synthesized carbide and nitride MXenes. The MS3 method demonstrated flexibility in large-scale production and the prepared MXenes showed excellent electrochemical properties for high-rate Li-ion storage.

Summary: The colorimetric detection of trace cobalt ions (Co2+) in electrolyte of zinc smelting plants is achieved using polyvinylpyrrolidone functionalized silver nanoparticles (PVP-AgNPs) even in high zinc ion concentration solutions. The strong attenuation of Co2+-related signals in ultraviolet-visible (UV-vis) extinction spectra caused by high concentration of Zn2+ is overcome, allowing for detection of 1-6 mg/L Co2+ in a 50 g/L Zn2+ solution. Systematic analysis techniques reveal the strong anti-interference ability and mechanism understanding for trace Co2+ detection in high-concentration Zn2+ solution. These results expand the application of AgNPs as colorimetric sensors to industrial solutions, providing a new strategy for detecting trace-metal ions in industrial plants.

Summary: The emergence of the sharing economy has had a significant impact on consumer purchase behavior and firms' operations management. Many manufacturers have entered the sharing market to capture more market shares by providing rental services through a third-party or self-built platform. This paper develops an analytical framework to examine the conditions for a manufacturer to participate in product sharing. The findings suggest that a manufacturer can benefit from involvement in the sharing market if consumers highly value and have a need for shared products, or if the cost of building a platform is low. However, the manufacturer's participation in the sharing market always negatively affects the retailer's profit.
