    Functionalized porous carbon materials (PCMs) were prepared by calcining rose pomace as raw material and KOH as activator at high temperature in a resistance furnace at 500 ℃ to investigate the adsorption performance of PCMs for the removal of methylene blue in water.The parameters for the preparation of PCMs were impregnation ratio of 1:1, impregnation time of 4 h, and activation time of 50 min.The PCMs were characterized by scanning electron microscope, Fourier transform infrared spectroscopy spectrometer, and pore size analyser. Characterised by scanning electron microscope, Fourier transform infrared spectrometer and pore size analyser, the PCMs were characterised by the presence of a variety of functional groups on the surface, the specific surface area of 285.112 m²/g, the average pore size of 4.2 nm, the total pore volume of 0.1589 cm³/g, and the percentage of mesopores was 54.05%. Taking the removal rate of methylene blue in printing and dyeing wastewater as an index, the preferred results of one-way experiment were: the dosage of PCMs was 0.15 g, the initial concentration of methylene blue was 80 mg/L, the initial solution pH=11, and the adsorption time was 4 h, under which the removal rate of methylene blue by PCMs could be up to 99.52%; and the optimal adsorption conditions of PCMs obtained from the response surface experiment were as follows: the PCMs The optimal adsorption conditions for PCMs were: PCMs dosage of 0.153 g, initial concentration of methylene blue of 64.35 mg/L, and pH=10.93, which predicted that the removal rate of methylene blue could reach 100%. Kinetic analysis showed that the adsorption of PCMs on methylene blue solution conformed to the quasi-secondary kinetic model (R2=0.9564), and the adsorption isotherm was well fitted by Freundlich (R2=0.9580).

    视网膜退行性疾病是全球不可逆视力丧失的主要病因。这类疾病的共同特征是视网膜(眼球后部的感光层)中的感光细胞(视杆细胞和视锥细胞)逐渐退化。然而,视网膜中的其他神经元(包括双极细胞、无长突细胞、水平细胞和视网膜神经节细胞)通常仍能维持大部分功能,并通过视神经维持与视觉皮层的连接。视网膜假体的设计初衷是通过人工刺激这些存活的视网膜神经元来提供有用的视觉感知,但大多数系统面临依赖外部电源以及对视网膜神经元刺激有限等挑战。在《Science》上,Wang等研究人员提出了一种由碲纳米线网络构成的视网膜假体,该技术在解决部分现有局限的同时,亦能响应比视锥细胞和视杆细胞更广的电磁波谱范围。

    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.

    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.

    Grasping the spatial and temporal evolution of transportation carbon emissions in the western region is of great significance for promoting the high-quality development of transportation in the west and narrowing the gap between the east and the west. In this paper, on the basis of measuring the transportation carbon emissions of 11 provinces in the western region from 2013 to 2022 using the "top-down" method, the natural discontinuity method, standard deviation ellipse method and spatial correlation network method are used to reveal the evolution law from the three dimensions of regional non-equilibrium distribution characteristics, center of gravity transfer trajectory and spatial correlation. The study shows that: (1) The growth trend of transportation carbon emissions in the west is slow, and the overall unbalanced regional distribution is characterized by "high in the middle and low in the north and south"; (2) The center of gravity of transportation carbon emissions shifts from the northwest to the southwest, and the difference between the level of transportation in the area of center of gravity and the rest of the provinces increases due to the impacts of location, policy, and development, and the centripetal convergence force is enhanced; (3) There is a significant spatial correlation in the western transportation carbon emissions. There is a significant spatial correlation effect of transportation carbon emissions in the west, in which the overall correlation effect in the policy and economic drive there is an upward trend, the local correlation effect of the phenomenon of bifurcation, Northwest and Southwest China are respectively in the "low-low" and "high-high" aggregation area. The northwestern and southwestern regions are in the "low-low" and "high-high" agglomeration zones, respectively, and have formed a certain range of agglomeration effects with neighboring provinces.

    As a mainstream science and technology in the new era, brain-computer interface has been widely used in education, medical, military, business and other fields, and has many functions such as "non-contact information dissemination", "deep reinforcement of human body functions", "efficient data transmission", etc. for enabling intelligence activities. The "non-contact information dissemination", "deep enhancement of human body functions", "efficient data transmission" and other functions have profound practical significance for the development of intelligence activities. By analysing the specific functions of brain computer interface technology for intelligence activities and the real risks of applying brain-computer interface technology in intelligence activities, we have constructed a compliance and protection mechanism that ranges from the guidance of principles to the anchoring of rules, and we strive to effectively safeguard the comprehensive application of brain-computer interface technology in the field of intelligence. In addition, it is necessary to adhere to the principle of preventive interest protection, the principle of interest level protection, and the principle of combining punishment and reward in the process of application, and dissolve the risks that brain-computer interface technology may face in the application of intelligence field from five aspects: the protection of individual's right to self-determination, the formulation of privacy compliance protection strategy, the strengthening of the supervision responsibility of the intelligence organisation, the improvement of the data security review system, and the formulation of the rewards and punishments mechanism for the protection of data compliance.

    The concept of "all-age friendliness" is a nascent but profound topic that impacts the spatial quality and future development of cities. Addressing issues such as insufficient refinement and mismatches between age groups and spatial needs in current urban planning and construction, this study focuses on the main urban area of Wuhan as a research subject. Leveraging big data from online public opinion, combined with techniques such as natural language processing and geospatial statistical analysis, we identify critical spatial issues related to different age groups and their distribution characteristics. The results reveal that spatial issues related to all age groups vary in content and emphasis. Old communities, schools and their surrounding neighborhoods, as well as commercial and office areas, are prone to issues specifically related to certain age groups. Urban transportation spaces and residential areas undergoing renewal are more likely to encounter issues pertaining to all age groups. Conversely, blue and green public spaces represent the least problematic spatial types. Based on these findings, this study provides guidance for the nascent exploration of all-age friendly cities in China, focusing on two aspects: "supporting the use of specific age groups" and "facilitating shared access for all ages." This research contributes to the ongoing efforts in enhancing the urban spatial quality and inclusivity for all age groups.

    This article focuses on amorphous matters and reviews recent advances in amorphous materials and physics. More recently, more than 30% of the lunar soil collected by China's Chang 'e-5 mission was found to be glassy, further confirming the widespread existence of amorphous matter in the universe. Topological order and inhomogeneity may be hidden behind the seemingly chaotic structure of amorphous materials, so amorphous matters have strange genetic, sensitive and relaxation behaviors, and show a series of excellent physical and chemical properties, such as extreme stability, super-plasticity, super mechanical behavior and excellent soft magnetic properties. The new generation of Zr-based and Fe-based amorphous alloys developed based on order regulation and high flux technology are successfully applied to core components such as folding mobile phone hinges and new energy vehicle motors, indicating that amorphous matters have irreplaceable application advantages. The future development of amorphous matters should focus on introducing a new paradigm of material research, attaching importance to the importance of process innovation, promoting the cross-integration of multi-disciplinary fields, giving full play to the advantages of advanced characterization technology and large scientific devices, and creating a whole-chain innovation model for production, university and research, so as to actively promote the rapid development of amorphous materials and physics, and expand the application of amorphous matters in high-tech fields. Make the future of mankind a better place.
