Synergistic carbon-sulfur co-roasting driven sustainable and selective recovery of lithium from spent ternary lithium-ion batteries.

Spent lithium-ion batteries (LIBs) contain high-value strategic metals which are essential for the sustainable resource utilization and eco-environment conservation. Conventional recycling technologies usually involve complicated procedures, high energy consumption and hazardous gas emissions. Hence, a novel process based on "C/S synergistic roasting - water leaching" is put forward to selective and environment-friendly recovery of lithium from spent LIBs.

[Carbon Peak Prediction of Energy Consumption in China： Based on STIRPAT Extended Model].

Achieving carbon peak before 2030 and carbon neutrality in 2060 is the solemn commitment of the Chinese government to the international community. It is important to scientifically identify the key influencing factors and accurately predict carbon peak value and time for achieving the dual carbon targets in China. On the basis of the economic and energy consumption data from 1980 to 2022， a STIRPAT extended multivariate-nonlinear model was built， which was fitted by a ridge regression to examine the relationships between carbon emissions of energy consumption and seven influencing factors， including population， GDP per capita， energy intensity， secondary industry proportion， fossil energy proportion， electrification rate， and urbanization rate.

Inflammatory markers including NLR, AFR and SII as prognostic factors in neuroblastoma.

Neuroblastoma (NB) is a common pediatric solid tumor, particularly in children under 2 years.

Emission fluxes of nitrous acid (HONO) from livestock and poultry wastes.

Gaseous nitrous acid (HONO) is a critical contributor to daytime hydroxyl radical in the troposphere. Livestock farming has been recognized as an overlooked HONO source, but the lack of detailed flux measurements from livestock and poultry wastes would cause uncertainties in modeling its environmental impacts. Here, based on field flux measurements and laboratory experiments, we observed substantial HONO emissions from the composting of swine feces and chicken manure in the warm season, which might be mainly attributed to nitrification process in livestock and poultry wastes.

Evaluating the contribution of residential coal combustion to atmospheric nitrous acid (HONO) in winter.

Nitrous acid (HONO) is an important precursor of hydroxy radicals (OH) that determine atmospheric oxidation capacity and thus influence air quality and climate. Like vehicle exhausts and biomass burning, coal combustion is also recognized as a potential direct source of HONO. However, the quantification of HONO emissions from coal combustion is currently limited.

Numerical Simulation Study on the Solid-Carrying Capacity of Hydrate-Sediment Slurry in a Vertical Pipe.

Solid fluidization is a green mining developed method for seabed nondiagenetic gas hydrate reservoirs, which can safely and controllably transport hydrate to land through seabed mining, closed fluidization, and gas-liquid-solid multiphase lift.

Nano-wire spin Hall nano-oscillator fabricated by novel sidewall transfer lithography.

Spin Hall nano-oscillators (SHNOs) have garnered significant attention in the field of spintronics in recent years, particularly for their potential in neuromorphic computing.

Field-free spin hall oscillator based on giant magnetoresistance effect and its potential for electrical synchronization.

Spin Hall nano oscillators (SHNOs) have attracted much attention in recent years due to their great potential for applications in neuromorphic computation. However, the output power of SHNOs is very low and an external magnetic field is required to generate microwave signal continuously, which hinders the further development of SHNOs. In order to solve the two problems, we propose a new-type SHNO based on the giant magnetoresistance (GMR) effect, while retaining the advantage of the simple fabrication process of the conventional oscillator.

Nest Site Selection by Green Sea Turtles () and Implications for Conservation on Qilianyu, Xisha Islands, South China Sea.

The green sea turtle () is the only sea turtle species that breeds in China, and the largest remaining nesting grounds for green sea turtles in Chinese waters is found on the Qilianyu atoll of the Xisha Islands. Nesting site selection is particularly important for egg survival, and understanding the microhabitat characteristics of green sea turtle nesting sites is crucial for delineating priority conservation areas for nesting grounds. In this study, we aimed to examine the role of several microhabitat ecological factors in the selection of nesting sites and the success of nesting.

Advantages and disadvantages of current human enteric virus surrogates in soils and aquifers.

Groundwater is one of the main sources of drinking water, thus, human enteric viruses in groundwater could pose safety risks. Many enteric viruses enter drinking water sources through irrigation or recharge of contaminated water. It is therefore advised to test the potential transport risk with harmless surrogates before wastewater or recycled water is used for irrigation or groundwater recharge.
