N vacancies and OH/C=O co-modified g-C3N4 photoactivated peroxymonosulfate for the degradation of tetracycline: Synergistic promotion effect between excitons and carriers

Activation of peroxymonosulfate (PMS) to generate reactive oxygen species (ROS) for pollutant degradation via metal-free photocatalysts is an important green wastewater treatment and remediation method, but the pathway for generating ROS via exciton effects in catalysts is often overlooked. In this study, OH/C=O co-modified N-defective rod-shaped carbon nitride (Nv-CN-O) was designed and synthesized by soft template and alkali hydrothermal method. In the Nv-CN-O/PMS/Light system, there was a synergistic degradation of tetracycline (TC) by carriers and excitons, with a degradation rate 2.15 times higher than that of CN/PMS/Light. N vacancies and OH/C=O enhanced the adsorption to PMS, accelerated the charge transfer process, and activated PMS to generate ·O2− dominated reactive species. The functional group OH/C=O promoted the production of triplet excitons that through the energy transfer pathway to promote the production of 1O2. Abundant ROS were involved in the TC degradation process, and three possible TC degradation pathways were proposed. Nv-CN-O has strong anti-interference ability in actual water bodies, shows a promoting effect on the degradation of TC, which has practical application potential.

The rapid advancement of information technology has led to the convergence of telecommunications and computer technologies. This shift has also influenced consumer behavior, with a growing number of individuals becoming more accustomed to online shopping, resulting in an increasing number of e-commerce users. Shopee, the leading e-commerce platform in Indonesia, has the highest number of website visits, positioning it as the top e-commerce site in the country. The purpose of this study is to analyze how e-service quality, security, and promotions influence e-customer satisfaction with Shopee among Generation Z in Denpasar. The study employs a descriptive quantitative research method with a sample size of 100 respondents. The t-test results for e-service quality reveal a t-value of 5.930, which is greater than the critical value of 1.984, indicating a significant positive effect of e-service quality on customer satisfaction. Conversely, the security variable demonstrates a negative impact on customer satisfaction, with a t-value of -2.842, which is less than the critical value of 1.984. The promotion variable exhibits a positive effect on customer satisfaction, with a t-value of 4.916, exceeding the critical value of 1.984. Furthermore, the overall hypothesis is supported as the calculated F-value of 62.474 exceeds the F-table value of 2.70, indicating that e-service quality (X1), security (X2), and promotions (X3) collectively influence customer satisfaction (Y).

Influence of Mutation, Promotion And Compensation, on Employee Performance Through Job Satisfaction In Cross-Functional Programs at The Ministry Of Finance

For human resource development, enhancing organizational synergy and collaboration, the Ministry of Finance implements a cross-functional program involving mutation and promotion among Echelon I Units of the Ministry of Finance. The main point of this research is how job satisfaction and performance are affected by this cross-functional program, considering mutation, promotion, and compensation in their new positions. This research focuses on forty supervisory-level employees who are directly engaged in the cross-functional program, spread across various regions in Indonesia. The independent variables in this research are mutation, promotion, and compensation, while the dependent variable is performance, with job satisfaction acting as an intervening variable. The variables were measured using a Likert scale. Subsequently, data were analyzed using PLS 3.0. The research results indicate that mutation does not significantly influences job satisfaction, promotion and compensation, however, have a positive impact on job satisfaction. Job satisfaction, mutation, and compensation collectively affect performance, while promotion does not exert a significant influence on performance. Furthermore, job satisfaction does not mediate the relationship between mutation and performance, but it does mediate the effects of promotion and compensation on performance.

Comparison of Neurogenesis Promotion Effects between Cinnamoylquinic Acids in Neural Stem Cells from Adult Mice Brains.

Caffeoylquinic acids (CQAs) and feruloylquinic acids (FQAs), as cinnamoylquinic acids, have neurogenesis promotion effects. We studied for the first time the neurogenesis-enhancing effect of 3,4,5-tri-feruloylquinic acid (TFQA) compared to 3,4,5-tri-caffeoylquinic acid (TCQA), which has a similar structure, and explored their different cellular and molecular mechanisms in neural stem cells (NSCs) of mice brains. After 2 weeks of incubation, we first assessed the number and size of NSCs in TCQA and TFQA treatments. In NSCs treated for TCQA and TFQA, the NSC proliferation gene expression as well as neuronal and glial cell differentiation gene expressions improved. In the microarray assay, the erythroblastic oncogene B (ErbB) signaling pathway, as the common signaling of TCQA and TFQA treatments, was focused on and discussed. In our study, TCQA and TFQA treatments in NSCs showed a significant performance on improving synapse growth and neurogenesis compared with no treatment of NSCs. The two treatments in NSCs also had a significant activation of the ErbB signaling pathway, protein kinase B (AKT), and mitogen-activated protein kinase (MAPK) kinases. In particular, the TCQA-expressed proliferation gene myelocytomatosis oncogene (Myc) had the greatest connections significantly. TFQA treatment remarkably regulated the differentiation gene jun proto-oncogene (Jun), which was the gene with greatest direct relations, while Myc was also induced in TFQA treatment. In the overall quantitative real-time polymerase chain reaction (PCR) assay, TFQA had more outstanding neural proliferation and differentiation capabilities than TCQA in NSCs. Our study suggests that TFQA has greater therapeutic potential in neurogenesis promotion and neurodegenerative diseases compared with TCQA.

The impact of port green competitiveness on the hinterland economy: A case study of China.

In the global trade landscape, ports are not only critical nodes for the transportation of goods but also increasingly recognized as key factors driving sustainable development through their green competitiveness. This paper takes a green competitiveness perspective to delve into the interactive relationship between port development and the hinterland economy, aiming to provide a theoretical foundation and policy recommendations for the green development of ports. An evaluation index system for green competitiveness of ports was constructed, and a combination of the Slacks-Based Measure (SBM) and the Entropy Weighted-Technique for Order Preference by Similarity to Ideal Solution (EW-TOPSIS) method was employed to quantitatively measure and assess the 25 major coastal ports and their hinterland economic systems in China. The study reveals that the overall green competitiveness of these major coastal ports is on the rise, yet notable disparities exist among individual ports. Regionally, the green competitiveness of the Yangtze River Delta port group stands out, while that of the Bohai Rim, southeastern, Pearl River Delta, and southwestern coastal port groups is relatively low. Empirical analysis conducted in this paper demonstrates the positive impact of port green competitiveness on the hinterland economic system, particularly its significant role in enhancing the total and quality aspects of the hinterland economy. Furthermore, it was found that the green competitiveness of ports exerts a more pronounced promotional effect on the hinterland economies of the Yangtze River Delta and Pearl River Delta port groups compared to that on the Bohai Rim, southeastern, and southwestern coastal port groups. The results of this paper also hold important guiding value for optimizing the allocation of port resources, promoting port technological innovation, and improving port environmental management, contributing to the harmonious coexistence and long-term development of ports and their hinterlands.

Divergent responses of soil aggregation and aggregate-carbon to fertilization regimes jointly explain soil organic carbon accrual in agroecosystems: A meta-analysis

Soil aggregation can be substantially affected by fertilizers and contributes to soil organic carbon (SOC) sequestration in agroecosystems. However, the mass and C distributions in different aggregates in responses to fertilization regimes are not often synchronous, which may largely affect soil C storage and stability. We conducted a meta-analysis of 2440 paired observations from 63 publications to assess the fertilization effects (i.e. inorganic, organic, and their combinations) on soil aggregation and aggregate-associated OC, as well as their linkages to the stimulated bulk soil C. Overall, fertilizer application significantly increased the mean weight diameter of soil aggregates by 27.8%. The proportion of large (> 2mm) and small (0.25-2mm) macroaggregates were significantly increased by 19.8% and 17.2%, and that of microaggregate (0.053-0.25mm) and silt-clay fraction (< 0.053mm) were significantly decreased by 6.0% and 18.4%, respectively. In contrast, fertilization significantly increased C concentration in all aggregates. Organic fertilizer applications had remarkably greater effects than inorganic fertilizer applications on soil C concentration but the effects declined with decreasing aggregate size (from 36.5% to 13.2%), while that of inorganic application changed very little among aggregates (from 14.1% to 10.0%). The fertilizer effects on soil aggregation and aggregate-associated OC divergently responded to the gradients of major agronomic conditions (i.e. climate, soil properties, and duration). Organic fertilizer applications tended to have distinctly greater promotion effect than solely inorganic fertilizer applications with temperate climate, neutral-to-alkaline pH and more sand-like texture of soil. The importance of mineral- rather than larger size aggregate-associated OC in contributing to the bulk SOC pool tended to increase in the long term. The inorganic-organic combinations exhibited the most lasting effect on SOC accrual. In conclusion, the responses of bulk soil C to fertilizer applications were not always in accordance with those of soil aggregation, but can be well explained when jointly considering soil aggregate C. Our findings highlight the varying contributions of aggregates to the soil C pool in diverse and complicated agronomic situations, which are important to the agricultural C sink stability.

Selection Process Based on Advancing the Development of a Science and Technology Law System with Chinese Features

The significance of advancing socialist S&amp;T legal system building with Chinese features is examined in this paper, along with the extensive effects it has on S&amp;T innovation and economic growth. Against the backdrop of an increasingly competitive global scientific and technology landscape, China’s ability to innovate and achieve sustainable growth hinges on the establishment of an ideal science and technology legislative framework. This essay first examines the primary obstacles to China’s development of a science, technology, and innovation (S&amp;T) legal system, including inadequate protection for intellectual property rights, a flawed process for transforming scientific and technological advancements, and an insufficient system for encouraging enterprise innovation. Then, this research presents a quantitative analysis model to optimize the path of science and technology legal building by applying the improved particle swarm optimization method (PSO). The model takes into account a wide range of variables, including the degree of intellectual property protection, the strength of legal backing, the pace at which scientific and technological advancements are transformed, etc. Through the analysis of simulation data, the model also confirms the promotion effect of the legal system construction on the quantity of patent applications, the success rate of innovation projects, the enterprise R&amp;D expenditure, and the expansion of the local economy. The study’s findings demonstrate that bolstering the science and technology legal system can effectively encourage businesses to boost R&amp;D investment and foster regional economic development in addition to greatly raising the quantity of patent applications and the success rate of innovation projects. The rigorous intellectual property protection laws and ideal legal framework for the conversion of accomplishments greatly boost the regional innovation vitality and economic efficiency, particularly in the case study of Zhongguancun in Beijing and East China. Moreover, adaptive weighting is used to enhance the PSO algorithm and optimize the development of science and technology legal system’s comprehensive performance index, thereby confirming the model’s viability and efficacy. The study’s findings offer theoretical justification and helpful advice for China’s development of a science and technology legal framework, which is crucial for fostering innovation in these fields and boosting the country’s competitiveness.

Investigation of Long-term Promotion Effects on Market Baskets: A Dynamic Bayes Network Approach

Investigation of Long-term Promotion Effects on Market Baskets: A Dynamic Bayes Network Approach

Decoding the Promotional Effect of Iron in Bimetallic Pt-Fe-nanoparticles on the Low Temperature Reverse Water-Gas Shift Reaction.

The reverse water-gas shift (RWGS) reaction is a key technology of the chemical industry, central to the emerging circular carbon economy. Pt-based catalysts have previously been shown to effectively promote RWGS, especially when modified by promoter elements. However, their active states are still poorly understood. Here, we show that the intimate incorporation of an iron promoter into metal-oxide-supported Pt-based nanoparticles can increase their activity and selectivity for the low temperature reverse water-gas shift (LT-RWGS) substantially and drastically outperform unpromoted Pt-based materials. Specifically, the study explores the promotional effect of iron in Pt-Fe bimetallic systems supported on silica (PtxFey@SiO2) prepared by surface organometallic chemistry (SOMC). The most active catalyst (Pt1Fe1@SiO2) shows high selectivity (>99% CO) toward CO at a formation rate of 0.192 molCO h-1 gcat-1, which is significantly higher than that of monometallic Pt@SiO2 (96% sel. and 0.022 molCO h-1 gcat-1). In-situ diffuse reflectance FT-IR spectroscopy (DRIFTS) and X-ray absorption spectroscopy (XAS) indicate a dynamic process at the catalyst surface under the reaction conditions, revealing distinct reaction pathways for the monometallic Pt@SiO2 and bimetallic PtxFey@SiO2 systems.

Highly catalytic performance for the selective C–H bond oxidation of p-chlorotoluene over Co, Cr co-doped OMS-2 catalyst

Using O2 as an oxidant, developing a non-noble metal catalyst for the selective catalytic C–H bond oxidation of p-chlorotoluene is desirable and challenging. In this work, a series of Co, Cr co-doped OMS-2 (Octahedral Molecular Sieve-2) catalysts were prepared by a conventional refluxing method. It was found that the incorporation of Co and Cr improved the catalytic activity for the selective oxidation of p-chlorotoluene to p-chlorobenzaldehyde. Among these catalysts, CoCr/OMS-2 (Co: Cr = 1: 1, mass ratio), the best catalyst, shows that the conversion and the selectivity of p-chlorobenzaldehyde is 94.8 % and 94.3 %, respectively. The enhanced catalytic activity was due to the larger specific surface area and even dispersion of active components. The characterization results also disclosed that the co-doping of Co and Cr increased the oxygen vacancy and enhanced the ability to activate the surface lattice oxygen. Additionally, density functional theory calculations demonstrated that co-doping of Co and Cr promoted the adsorption of p-chlorotoluene and O2, and decreased the energy barrier of rate-determining step (the conversion of p-chlorobenzyl alcohol to p-chlorobenzaldehyde). Besides, when H2O was added to the reaction system as the second solvent, the activation and dissociation of O2, and the formation of p-chlorobenzaldehyde were facilitated, in agreement with the experimental results. This work demonstrated the promotional effect of Co, Cr co-doped into OMS-2 catalyst and the role of H2O for the selective oxidation of p-chlorotoluene.

An Experimental and Kinetic Modeling Study of the Laminar Burning Velocities of Ammonia/n-Heptane Blends

Ammonia is carbon-free and is a very promising renewable fuel. The ammonia/diesel dual-fuel combustion strategy is an important combustion strategy for ammonia internal combustion engines. To achieve clean and efficient combustion with a high ammonia blending ratio in ammonia engines, it is important to thoroughly investigate the combustion characteristics and chemical reaction mechanisms of ammonia/diesel fuel blends. Based on the constant volume combustion vessel experiments, the laminar burning velocities (LBVs) of ammonia/n-heptane blends were measured at the conditions of an ammonia–energy ratio of 60–100%, at initial pressures of 0.1–0.5 MPa and initial temperatures of 338–408 K, and under an equivalence ratio regime of 0.8–1.3. The experimental results indicate that the laminar burning velocities of ammonia/n-heptane fuel blends increase with a decreasing ammonia–energy ratio. Specifically, with an ammonia–energy ratio of 60%, an initial temperature of 373 K, an initial pressure of 0.1 MPa, and an equivalence ratio of 1.1, the measured LBV is approximately 20 cm/s, which is about 61% faster than that of pure ammonia flames under the same conditions. A previously developed chemical kinetic mechanism is employed to simulate the new experimental data, and the model exhibits overall good performance. The sensitivity analyses have been conducted to highlight the important reaction pathways. The elementary reaction O2 + Ḣ&lt;=&gt;Ö + ȮH demonstrates the most significant promotional effect on the laminar burning velocities, while the interaction reaction pathways of via H-abstraction from n-heptane by ṄH2 radicals are not showing obvious effects on the simulation results under the studied conditions.

Effect of Plant Growth Promoters and Herbicides on Growth, Yield Attribute and Yield of Kharif Hybrid Maize (Zea mays L.)

A Smart Design of Non-Noble Catalysts for Sustainable Propane Dehydrogenation.

Propane dehydrogenation (PDH), an important process for propylene synthesis, relies on expensive noble metals or highly toxic oxides as catalysts. In a recent publication, Gong and co-workers report a breakthrough discovery for PDH by introducing a sustainable catalyst composed of titanium oxide overlayers encapsulating nickel nanoparticles, termed Ni@TiOx. This innovative catalyst showcases exceptional performance in PDH, exhibiting high propylene selectivity and stability under industrially relevant conditions. The study elucidates the role of defective TiOx overlayers and the electronic promotional effect of subsurface Ni in enhancing catalytic activity, translating a traditional model catalyst system into a sustainable industrial catalyst for low-carbon energy and the chemical industry.

Comparative Study of PtM (M=Cu, Zn, Ga, Mn, Fe, In, Ce) Bimetals on Zincosilicate for Propane Dehydrogenation Reaction.

Silicoaluminate zeolites have relatively strong Brönsted (B) acid properties that can easily lead to deep cracking reactions, making them less favourable as carriers for propane dehydrogenation. Here, we utilise zincosilicate zeolite with less B-acid produced by the introduction of the heteroatom Zn into the framework as a carrier, followed by simultaneous ion exchange (IE) of M monometallic or PtM bimetallic (M = Cu, Zn and Ga, etc.). The optimized PtZn/Zn-4 exhibits a superior propane dehydrogenation performance over PtCu/Zn-4 and PtGa/Zn-4, which can achieve a propane conversion of about 30% in a pure propane atmosphere at 550 °C and can be operated for at least 168 h without significant deactivation. Characterization techniques such as spherical aberration corrected transmission electron microscopy, in situ X-ray photoelectron spectroscopy, and in situ diffuse reflectance infrared fourier transform spectroscopy with different gas adsorptions are used to investigate these PtM@zeolite catalysts in order to deepen the understanding of acid site identification, promoter effect and catalysis.

Does continuous innovation failure lead firm innovation to hesitate to press forward?: Evidence from Chinese-listed technology-intensive industries firms

Continuous innovation failure is a common phenomenon in the process of firm innovation. However, little is known about how continuous innovation failure affects firm innovation, and what factors moderate the relationship between them. Using the empirical data from China’s technology-intensive industries listed firms, we find that continuous innovation failure doesn’t lead firm innovation to hesitate to press forward but promotes firms to increase innovation. Managerial overconfidence strengthens the positive impact of continuous innovation failure on firm innovation. Interestingly, managerial power does not enhance but weakens the regulatory role of managerial overconfidence. Further analysis shows that continuous innovation failure will prompt firms to increase exploratory innovation and reduce exploitative innovation. Heterogeneity analysis finds that the promotion effect of continuous innovation failure on firm innovation will be enhanced in firms with higher financial redundancy, but will be weakened in firms with higher R&D subsidies.

Lymphoma cell-driven IL-16 is expressed in activated B-cell-like diffuse large Bcell lymphomas and regulates the pro-tumor microenvironment.

The activated B-cell-like subtype of diffuse large B-cell lymphoma (ABC-DLBCL) displays a worse outcome than the germinal center B-cell-like subtype (GCB-DLBCL). Currently, targeting tumor microenvironment (TME) is the promising approach to cure DLBCL with profound molecular heterogeneity, however, the factors affecting the tumor-promoting TME of ABCDLBCL are elusive. Here, cytokine interleukin-16 (IL-16) is expressed in tumor cells of ABCDLBCL and secreted by the cleavage of active caspase-3. The serum IL-16 levels are not only a sensitive marker of treatment response but also positively correlated with unfavorable prognosis in DLBCL patients. While IL-16 shows few direct promotional effects on tumor cell growth in vitro, its bioactive form significantly promotes tumor progression in vivo. Mechanically, IL-16 increases the infiltration of macrophages by the chemotaxis of CD4+ monocytes in the TME enhancing angiogenesis, and the expression of cytokine IL-6 and IL-10, as well as decreasing T cell infiltration to accelerate tumor progression. This study demonstrates that IL-16 exerts a novel role in coordinating the bidirectional interactions between tumor progression and the TME. IMM0306, a fusion protein of CD20 mAb with the CD47 binding domain of SIRPα, reverses the tumorpromoting effects of IL-16,which provides new insight into treatment strategy in ABC-DLBCL.

Enhancing the Self-Propelled Motion of Hydrogen Peroxide Fueled Active Particles with Formic Acid and Other Oxygen Scavengers.

We report enhanced active particle motion in hydrogen peroxide-fueled self-diffusiophoretic active particle systems of up to 400% via addition of low concentrations of oxygen scavenging agents such as formic acid (as well as other organic acids, hydrazine, and citric acid), whereas active motion was inhibited at higher concentrations. Control experiments showed that enhanced motion was decoupled from catalytic hydrogen peroxide decomposition rate and insensitive to particle surface chemistry. Experimental results point to bulk oxygen scavenging as the cause for the enhanced active motion, representing a realization of recently predicted promotional effects of product sinks on self-diffusiophoretic motion. Diminished active motion at high oxygen scavenger concentrations was attributed to catalytic site blocking by adsorbed solute.
