Charting a sustainable tomorrow: Advancing urban low-carbon economies through comprehensive evaluation and promotion.

With the world population growth, energy consumption and the rapid development of industrial economy, a large amount of carbon emissions has brought destruction and threats to the earth's environment on which human beings depend. The development of low-carbon economy has become the consensus of governments all over the world and has been vigorously advocated & promoted. This paper focuses on the top five global GDP nations in 2022: The United States, China, Japan, Germany, and Britain.

How digital finance promotes renewable energy consumption in China?

This study uses a quantitative methodology to investigate how the rise of digital money has affected efforts to increase green energy use in China. This work contributes to the body of knowledge by using a number of empirical methods, such as regression analysis, parametric quantile estimation, stability diagnostic tests, and sensitivity analysis. This study's results further demonstrate the importance of digital financing in easing the adoption of renewable energy sources throughout China.

Microstructures and Mechanical Properties of V-Modified Ti-Zr-Cu-Ni Filler Metals.

TA2 titanium alloy was brazed with Ti-Zr-Cu-Ni-V filler metals developed in a laboratory. The melting properties, the microstructures, phase compositions of filler metals and wettability, erosion properties, tensile properties of the brazed joint were studied in detail. The results show that with the increase of V content, the solidus-liquidus temperature of Ti-Zr-Cu-Ni-V filler metals increased, but the temperature difference basically remained unchanged, trace V element had a limited influence on the melting temperature range of Ti-Zr-Cu-Ni filler metals.

The spatial characteristics of embodied carbon emission flow in Chinese provinces: a network-based perspective.

Combining the multi-regional input-output model with complex network technology, based on the provincial scale, this paper systematically describes the characteristics of the spatial network flow and its changing track of embodied carbon emissions among provinces in China from three dimensions of network structure, flow distribution characteristics, and spatial flow characteristics. Furthermore, the maximum spanning tree method is used to identify the spatial flow path of embodied carbon emissions between provinces and to distinguish the hierarchical status and roles of different provinces on the path. The research results show that the embodied carbon emission flow network among provinces has obvious small-world characteristics during the study, and the roles of different provinces in the network have significant heterogeneity.
