Teaching Reform of Materials Science and Engineering Foundation under the Background of "Carbon Peak and Carbon Neutral"

Universities have always been pioneers, advocates and leaders of economic and social reform, and should play a key role in this systematic change. In July 2021, the Ministry of Education issued the Action Plan for Carbon-neutral Scientific and Technological Innovation in Institutions of Higher Learning, which clarified the major tasks for universities to provide scientific and technological support and talent support for the dual-carbon target. The first to realize the campus carbon neutral, and promote the carbon neutral scientific and technological innovation and the training of high-quality talents with the construction of campus environment, is a positive response to the national strategy and the action plan of the Ministry of Education. In the Work Plan for Strengthening the Construction of the Training System for Higher Education issued in May 2022, the Ministry of Education particularly stressed that universities should strengthen green and low-carbon education, strengthen the construction of teaching resources in the field of "dual-carbon", and promote the high-quality training of "dual-carbon" related professionals. The key to controlling dual carbon lies in material technology. Therefore, it is particularly important to cultivate materials professionals with dual carbon concepts and related technologies. Based on this, the members of our teaching group have carried out a series of teaching reforms for the course "Fundamentals of Materials Science and Engineering" based on years of frontline teaching experience. They have combined theoretical teaching and practical teaching, providing strong guarantees for cultivating competitive talents in the field of dual carbon control.

The Changing Course, Evolutionary Mechanism and Advancing Path of the Construction of Emergency Plan System

In the face of the practical failure of emergency plan application and the frequent occurrence of emergencies, the construction of emergency plan system should be further strengthened. This paper combs the development process of the construction of the emergency plan system, analyzes the evolution mechanism of its changes from the external dynamic mechanism, the internal dynamic mechanism and the direct dynamic mechanism, and on this basis, puts forward the development path of the emergency plan system construction. It is found that the construction of emergency plan system has gone through three stages: forming, deepening and adjusting. And its development force is composed of institutional situation, path dependence and key nodes.

Substantive or symbolic ? The strategic choice of sustainable environmental strategy for enterprises induced by the new environmental protection law

AbstractThe new “Environmental Protection Law” (abbreviated as NEPL) holds milestone significance for the construction of China's ecological legal system. However, evidence regarding the impact of NEPL on sustainable environmental strategy (abbreviated as SES) still lacks empirical analysis. This study aims to examine the mechanisms and boundary conditions through which the NEPL influences SES. Utilizing a difference‐in‐differences approach, an empirical analysis is conducted on the data of listed companies on the Shanghai and Shenzhen A‐shares from 2008 to 2021. The findings are as follows: (1) NEPL has significantly promoted both the substantive environmental strategy (abbreviated as SUB) and symbolic environmental strategy (abbreviated as SYM) of heavily polluting enterprises. Compared with SYM, the impact of NEPL on SUB is more significant. (2) Analyst coverage plays a significantly positive moderating role in the relationship between NEPL and SUB, while managerial myopia plays a significantly positive moderating role in the relationship between NEPL and SYM. (3) Environmental legitimacy pressure exerts a mediating effect on the relationship between NEPL and SES. The research findings enrich existing theories related to strategic choice and environmental policy under government intervention and provide policy recommendations for enterprises to achieve sustainable development in the context of NEPL.

Research on the Development and Policy Evolution of CCUS Industry at Home and Abroad

CCUS is internationally recognized as one of the three major pathways to achieve carbon neutrality goals. It is an important choice for realizing zero emissions from large-scale fossil energy utilization and a feasible technological solution to offset carbon emissions in industries such as power, steel, and cement where emissions reductions are challenging. Systematic analysis of the development and policy evolution of the CCUS industry at home and abroad can provide theoretical basis and practical guidance for China's energy transition and development under the background of carbon emission peaking and achieving carbon neutrality. Guided by the strategic goals of national energy security, carbon emission peaking, and achieving carbon neutrality, this study aims to analyze the global development process and stage characteristics of the CCUS industry, investigate the supporting policies in the CCUS field and their evolution patterns, summarize the current status and trends of the CCUS industry at home and abroad, and provide reference for the implementation of national energy green and low-carbon transformation and the construction of a new energy system. In terms of industry, European and American countries emphasize national-level technological guidance and macro-control. The United States has introduced the progressive 45Q tax credit policy, and the European Union has included CCUS in its carbon trading system. The US National Carbon Capture Center provides a testing environment and facilities for CCUS technology research and development, and has established a carbon dioxide industry cluster and transportation hub. In terms of policies, tax credits and carbon trading policies in Europe and America have attracted various types of capital investment, establishing a relatively complete legal framework system. These regions have been leading in CCUS technology research and deployment, holding dominant positions and decision-making power in mainstream international CCUS organizations such as the CSLF, IEA, GCCSI, and OGCI. This study benchmarks the forward-looking and strategic development status of the CCUS industry at home and abroad, elucidates the challenges facing CCUS industry development, and proposes future trends and policy support needs for the CCUS industry. The research reveals that Europe and America emphasize national-level technological guidance and macro-control, focusing on the construction of regional industrial networks and having established a relatively complete legal and regulatory framework system. Compared to other countries, China needs to establish national-level guidance on CCUS development, regional carbon dioxide capture and transportation networks, and enact specific laws, regulations, and technical standards for CCUS.

Enhancing myocardial infarction treatment through bionic hydrogel-mediated spatial combination therapy via mtDNA-STING crosstalk modulation

Myocardial infarction (MI)-induced impaired cardiomyocyte (CM) mitochondrial function and microenvironmental inflammatory cascades severely accelerate the progression of heart failure for compromised myocardial repair. Modulation of the crosstalk between CM mitochondrial DNA (mtDNA) and STING has been recently identified as a robust strategy in enhancing MI treatment, but remains seldom explored. To develop a novel approach that can address persistent myocardial injury using this crosstalk, we report herein construction of a biomimetic hydrogel system, Rb1/PDA-hydrogel comprised of ginsenoside Rb1/polydopamine nanoparticles (Rb1/PDA NPs)-loaded carboxylated chitosan, 4-arm-PEG-phenylboronic acid (4-arm-PEG-PBA), and 4-arm-PEG-dopamine (4-arm-PEG-DA) crosslinked networks. An optimized hydrogel formulation presents not only desired adhesion properties to the surface of the myocardium, but also adaptability for deep myocardial injection, resulting in ROS scavenging, CM mitochondrial function protection, M1 macrophage polarization inhibition through the STING pathway, and angiogenesis promotion via an internal-external spatial combination. The enhanced therapeutic efficiency is supported by the histological analysis of the infarcted area, which shows that the fibrotic area of the MI rats decreases from 58.4% to 5.5%, the thickness of the left ventricular wall increases by 1-fold, and almost complete recovery of cardiac function after 28 days of treatment. Overall, this study reported the first use of a strong adhesive and injectable hydrogel with mtDNA and STING signaling characteristics for enhanced MI treatment via an internal-external spatial combination strategy.

A Study on the Distribution Dynamics, Regional Disparities, and Convergence of China’s Energy Transition

Abstract: Energy transition, as a crucial aspect of the country’s high-value-added economic development, involves the construction of an energy transition index system and empirical analysis using methods such as the entropy weighting method, kernel density estimation, Markov chain, Dagum Gini coefficient, σ-convergence, and β-convergence. This study measures the level of energy transition in 280 Chinese cities from 2010 to 2019 and analyzes their evolutionary trends, regional disparities, structural differences, and convergence. The findings reveal that China’s energy transition generally exhibits characteristics of “improvement in development levels and reduction in absolute disparities”. The disparities in energy transition primarily stem from developmental differences among the three major regions, displaying typical σ-convergence and β-convergence characteristics. This analysis contributes to understanding the real level and distribution features of China’s energy transition, providing a basis for identifying focal points for enhancing energy transition in the current and future stages.

Contemporary Aspects of Legal Doctrine and Interpretation - Challenges and Perspectives

In the countries where we have the construction of the legal system with the new laws, the ambiguity of the legal norms in the new laws in some cases is almost inevitable. But commenting on laws and judicial practice will be of great help to bring about the implementation of all legal norms as was the intention of the legislator, because the correct interpretation of legal provisions is a necessity of any legal order that creates a legal security for all citizens equally. Of course, the object of legal interpretation or clarification is not only written legal-civil norms, but also those that are part of customary law. The issue of interpretation of laws currently represents a fundamental concern for citizens and legal institutions, looking for a smart and innovative approach to address this issue effectively and sustainably. In this context, this paper aims to identify and analyze the advantages and challenges of legal doctrine and interpretation in the contemporary context.

Alkyl anchor–modified artificial viral capsid budding outside-to-inside and inside-to-outside giant vesicles

ABSTRACT The budding of human immunodeficiency virus from an infected host cell is induced by the modification of structural proteins bearing long-chain fatty acids, followed by their anchoring to the cell membrane. Although many model budding systems using giant unilamellar vesicles (GUVs) induced by various stimuli have been developed, constructing an artificial viral budding system of GUVs using only synthesized molecules remains challenging. Herein, we report the construction of an artificial viral capsid budding system from a lipid bilayer of GUV. The C-terminus of the β-annulus peptide was modified using an octyl chain as an alkyl anchor via a disulfide bond. The self-assembly of the β-annulus peptide with an octyl chain formed an artificial viral capsid aggregate. The fluorescence imaging and transmission electron microscopy observations revealed that the addition of the tetramethylrhodamine (TMR)-labeled octyl chain–bearing β-annulus peptide to the outer aqueous phase of GUV induced the budding of the capsid-encapsulated daughter vesicle outside-to-inside the mother GUV. Conversely, the encapsulation of the TMR-labeled octyl chain–bearing β-annulus peptide in the inner aqueous phase of GUV induced the budding of the capsid-encapsulated daughter vesicle inside-to-outside the mother GUV. Contrarily, the addition of the TMR-labeled β-annulus peptide to GUV barely induced budding. It was demonstrated that the higher the membrane fluidity of GUV, the more likely budding would be induced by the addition of the alkyl anchor–modified artificial viral capsid. The simple virus-mimicking material developed in this study, which buds off through membrane anchoring, can provide physicochemical insights into the mechanisms of natural viral budding from cells.

Dynamical analysis of a novel memristor-type chaotic map

As a unique nonlinear component, the discrete memristor, with its simple structure, is associated with the ability to lead to excellent chaotic performance in the construction of chaotic systems. This characteristic has elevated the discrete memristor to a hot topic in the field of chaos. This paper introduces a cosine hyperchaotic map. Numerical simulations reveal its rich dynamical behaviors. The chaotic map exhibits diverse chaotic control models, including partial amplitude control, total amplitude control, initial boosting, and parameter-offset boosting, with dynamical distribution diagrams plotted for amplitude control to quantify the range of amplitude modulation. Additionally, a localized boosting free region is identified, which exhibits extreme sensitivity to initial values. Dual offset parameters are introduced to control this localized boosting free region, enhancing the flexibility of the system. Finally, the map is implemented on STM32 to validate the numerical simulation results.

A low-cost, portable device for the study of the malaria parasite’s growth inhibition via microwave exposure

Recently, a novel method for the growth inhibition of malaria parasites using microwaves was proposed. However, the apparatuses used to demonstrate this method are high-cost and immovable, hindering the progression in this field of research, which is still in its early stages. This paper presents the redesign, construction, and validation of an equivalent system, converting it into a portable and low-cost system, capable of replacing the existing one. The proposed system is mainly composed of an RF generator (MAX2870), an RF amplifier (SKYWORKS 66292-11) and a graphical user interface. Likewise, the RF applicator proposed by the original study was redesigned, resulting in a five-fold improvement in return loss. The obtained results indicate that the proposed system achieves 90% parasite growth inhibition, matching the performance of its counterpart at less than 1% of its cost. These results represent a breakthrough for the creation of smaller, enhanced devices that open new possibilities for an alternative treatment to combat this devastating disease.

Research on the Construction of a Risk Assessment Indicator System for Transportation Infrastructure Investment under Public–Private Partnership Model

This paper is dedicated to developing a risk assessment indicator system applicable to transportation infrastructure investment projects in the public–private partnership (PPP) model. Initially, through practical research, literature reviews, and expert interviews, key risk factors for transportation infrastructure investment projects in the PPP mode were identified. Based on these risk factors, a preliminary risk assessment indicator system was established. Subsequently, the principal component analysis (PCA) was used to reduce the dimensions of the indicators, simplify the structure of the system, and highlight key risk factors. Simultaneously, the CRITIC-EWM method was applied to calculate the weights of the indicators. Furthermore, to validate the effectiveness of the indicator system, a questionnaire survey was conducted, collecting 314 responses. Structural equation modeling was applied to validate the effectiveness of the indicator system and examine its application value in practical risk management processes. The primary contribution of this study lies in proposing a method for constructing a risk assessment indicator system that combines quantitative and qualitative analyses, providing new theoretical and practical guidance for risk management of transportation infrastructure investment projects under the PPP mode.
