The discovery of bilayer nickelate superconductor La₃Ni₂O₇ under high pressure has attracted worldwide attention, in which theoretical research plays a vital role. So far, theoretical calculations show that the two e_g Ni 3d_x2-y2 and 3d_z2 orbitals in La₃Ni₂O₇ are crucial to the formation of superconductivity, while the O₂ p orbital also appears on the Fermi surface. Multi-orbital models have been proposed based on the above analysis. Various calculations show that La₃Ni₂O₇ has a s^± wave pairing symmetry although other pairing symmetries can be obtained. Theoretical calculations shows that the superconducting mechanism is unconventional and closely related to antiferromagnetic fluctuation. The vacancy of apical oxygen has a significant impact on the occurrence of superconductivity. The discovery of trilayer nickelate superconductor La₄Ni₃O₁₀ under pressure has further enriched the family of nickelate superconductors. And its electronic band structure, multi-orbital model, superconducting pairing symmetry and so on have been investigated and explored theoretically.

Under the background of the superpower games, the United States actively promotes the de Sinicization of key minerals and constructs a strategic blockade against China, which may seriously affect China's normal resource rights and interests. Based on the critical mineral related data released by the United States Geological Survey from 2013 to 2022, quantitative research was conducted from three perspectives: import dependence, market dynamics, and supply risk. The changes in the security of the critical mineral supply chain in the United States were elucidated, and the means and characteristics of strengthening the security of the critical mineral supply chain in the United States were analyzed. About 90% of critical minerals in the United States rely on imports, with China as its top supplier. The market dynamics of about 70% of critical minerals fluctuate violently, and market instability may amplify the import risk of critical minerals in the United States; About 32% of critical mineral supply risks are high or keep rising, and the production capacity of critical minerals further shifts to some thirdworld countries in Asia, Africa and South America, and the escalation of geopolitical crises may exacerbate mineral supply risks. Based on the analysis of the security situation of the key mineral supply chain in the United States and its security measures to strengthen supply chain, suggestions have been put forward, including systematic planning to respond to the strategic game of key minerals, enhance the influence on the international mineral resource market, deepen overseas development cooperation, and strengthen risk prevention and control.

Seismic water temperature observation instruments (abbreviated as thermometer) plays a key role in short and imminent earthquake prediction. However, for a long time, there has been a lack of field detection method with quantitative traceability, which is, mobile calibration method. In this paper, two kinds of mobile calibration methods of thermometers, namely in situ comparison method and constant temperature chamber comparison method, are proposed, and the influence of these methods on the continuity of observation data is preliminarily verified by field experiments. The results show that under the conditions of the experimental well, the standard deviations of the observation data of the measured instrument before and after mobile calibration are close, with the maximum difference of -0.0002℃, the maximum difference of the variation amplitude of the indication value of -0.0053℃, and the calculated results of interference degree (ID) of all<50%. The influence of mobile calibration method on instrument data continuity is in the acceptable range. Although the method has some limitations in the scope of application, it is still a potential scheme to realize the traceability of station operating thermometers.

To support the logistics industry’s sustainable growth, it is essential to identify the driving forces and the peak path of carbon emissions in the province’s logistics industry along the Belt and Road. Firstly, this paper uses the carbon emission coefficient method to calculate the carbon emissions of the provincial logistics industry along the Belt and Road from 2006 to 2021. Then, the generalized Divisia index method is used to decompose the driving factors of carbon emissions. Finally, combined with Monte Carlo simulation, three scenarios are set up to predict the carbon emissions of the logistics industry from 2022 to 2035, aiming to study the future carbon peak scenario and effective carbon peak path of the logistics industry along the Belt and Road. The results show that: (1) Among the factors that promote the increase of carbon emission, the effect of fixed asset investment and the added value of the logistics industry is significant. Among the factors that promote carbon emission reduction, investment carbon intensity and output carbon intensity have significant effects. (2) The northeast and northwest regions can achieve the 2030 carbon peak target under the government intervention scenario, and the Belt and Road can only achieve the carbon peak target under the technology breakthrough scenario. This means that to reach the carbon peak as quickly as possible, we should fully embrace both the functions of governmental intervention and technology innovation breakthrough.

This paper focuses on the latest progress of oil generation, storage, production and engineering transformation of Gulong shale oil in Songliao Basin and holds that the high oil generation and low hydrocarbon expulsion efficiency of Gulong shale provides important material basis for oil production. The micro-nano pore and fracture combination system widely developed in Gulong shale provides the spatial basis for shale oil reservoir. In terms of engineering transformation, engineering technologies such as increasing the proportion of guanidine adhesive fracturing fluid, using silt slug to plug micro-fractures near the well, reducing the number of clusters in the section, increasing the construction displacement, and using stress interference in a positive way are proposed to realize the joint network concept of "controlling near and expanding far" and improve the scale and degree of transformation. By quantifying the process and sequence of energy release through hydraulic elastic flooding, rock and fluid elastic flooding, and dissolved gas flooding, reasonable control of pressure and orderly release of elastic energy can be achieved to control the decline of volume development. Although the revolutionary transformation of continental facies shale oil from "oil generation" to "oil production" still faces major challenges in theoretical mechanism, the engineering technologies and benefit development, continental facies shale oilin a huge scale is one of the important goals to ensure national energy security in the future.

Technological talents are the core element for achieving self-reliance and self-improvement in China's science and technology, and innovation willingness is the key to stimulating the vitality of technological talents. This article takes 236

scientific and technological talents as the survey subjects, adopts the fuzzy set qualitative comparative analysis method, and explores the configuration path of multi factor synergy affecting the innovation willingness of scientific and technological talents under the TPB framework. Research has found that there are four driving types of high innovation willingness among technology talents, namely demonstrative norms innovation attitude driven, directive norms innovation attitude driven, endogenous attitudes subjective norm driven, and innovation attitude driven. Innovation attitude is an important condition for technology talents to generate innovation willingness; Directive norms and demonstrative norms are key elements in regulating the innovation willingness of scientific and technological talents, and there is a substitution relationship between the two; The perceived behavioral control of technology talents has a weaker effect on enhancing innovation willingness. This article reveals the complex causal mechanism of the synergistic effect of planned behavior theory elements on the innovation willingness of scientific and technological talents from a configuration perspective, providing important reference for organizations to cultivate the innovation willingness of scientific and technological talents.
