The presence of tetracycline (TC) has been detected in the human living environment, and its complex structure makes it difficult to degrade. The green and efficient utilization of electroactivated persulfate advanced oxidation technology for the degradation of tetracycline remains a challenge. In this study, N-doped reduced graphene oxide (N-rGO) was prepared using a hydrothermal treatment method with urea as the nitrogen source. Four different mass ratios of graphene oxide (GO) to urea were synthesized, and the optimal mass ratio was determined through degradation experiments of tetracycline. The N-rGO/EC/PMS three-dimensional electrocatalytic system was constructed, and the influence of the experimental data on TC degradation, such as initial pH, PMS dosage and voltage, was determined. Characterization analysis using scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), and other methods was conducted. The efficient catalytic ability of N-rGO was demonstrated through the generation of hydrogen peroxide ( H2O2) and consumption of peroxymonosulfate (PMS). The superiority of the three-dimensional (3D) electrochemical advanced oxidation process was proposed by combining different systems. Furthermore, the presence of hydroxyl radicals (.OH), persulfate radicals ( SO4 ·−), and singlet oxygen (1O2) was identified using electron spin resonance (ESR) technology. The utilization of N-rGO as a three-dimensional electrode, coupled with the advantages of PMS activation and electrochemical oxidation processes, is a promising method for treating organic pollutants in wastewater.

Single-atom Pd clusters anchored on t-BaTiO3 material was synthesized using hydrothermal and ultrasonic methods for the effective piezoelectric catalytic degradation of pollutants using vibration energy. XRD patterns of BaTiO3 loaded with monoatomic Pd were obtained before and after calcining, and showed typical cubic-phase BTO. TEM and HAADF-STEM images indicated single-atom Pd clusters were successfully introduced into the BaTiO3. The piezoelectric current density of the prepared Pd-BaTiO3 binary composite was significantly higher than that of the pristine BaTiO3. Under mechanical vibration, the nanomaterial exhibited a tetracycline decomposition rate of ~95 % within 7 h, which is much higher than the degradation rate of 56.7 % observed with pure BaTiO3. Many of the piezo-induced electrons escaped to the Pd-doped BaTiO3 interface because of Pd’s excellent conductivity. Single-atom Pd clusters help promote the separation of the piezo-induced electrons, thereby achieving synergistic catalysis. This work demonstrates the feasibility of combining ultrasonic technology with the piezoelectric effect and provides a promising strategy for the development of ultrasonic and piezoelectric materials.

Central bank digital currency (CBDC) is generally defined as the digital form of a country’s fiat currency. Based on the distributed ledger technology and other financial technology, CBDC could improve the efficiency of domestic and cross-border payments, increase payment safety and soundness, and promote financial inclusion. However, it is argued that the introduction of CBDC would threaten data security and invade personal privacy. Currently, this issue has received growing concern, and some recommendations are proposed by countries or international organizations, like privacy design, restrictions on public authorities and payment intermediaries, and establishing independent supervisory authority. Other suggestions include getting countries involved in international coordination and promoting the formation of unified standards. Among major economies, China is the first to launch CBDC, which is known as e-CNY. Based on an overview of the privacy protection legislation in China, this article attempts to describe the rules that should be followed when dealing with personal data generated in e-CNY circulation.

Graphitic carbon nitride (g-C3N4) has attracted extensive attention in energy storage due to its suitable and tunable bandgap, high chemical/thermal stability, earth abundance and environmental friendliness. However, its conductivity should be improved to work as the electrode materials in supercapacitors. In this report, we have prepared a two-dimensional composite (CN-PANI) based on g-C3N4 and polyaniline (PANI) by in-situ polymerization, which can be efficiently applied as electrode material for supercapacitors. The introduction of PANI can increase the conductivity of the electrode, and the porous structure of g-C3N4 can provide enough channels for the transport of electrolyte ions and improve the electrode stability. As a result, the obtained CN-PANI demonstrates excellent specific capacitance (234.0 F g− 1 at 5 mV/s), good rate performance and high cycling stability (86.2% after 10,000 cycles at 50 mV/s), showing great potential for high-rate supercapacitors.

Nitrogen-doped carbon dots (N-CDs), derived from the biomass (anthocyanin), are the novel additive to the nanocarbon materials, which is expected to bring a wide spectrum of novel applications. Moreover, metallic oxides are emerging for their unique potential for electrocatalysis. Herein, we report the synthesis of N-CDs for the selective detection of Fe3+ with a limit of detection of 2.57 μM in the range of 5–60 μM using ethylenediamine and H2O2 by a hydrothermal method. The obtained N-CDs displayed a spherical morphology with a particle size range of 2–7 nm and emitted blue luminescence at 394 nm under excitation at 319 nm. Meanwhile, we have demonstrated the fabrication of cost-efficient electrocatalysts for oxygen evolution reaction (OER) in an alkaline medium, employing N-CDs. Owing to the successful incorporation of N-CDs into NiO nanospheres, the resulting N-CDs/NiO with large surface areas, fast charge transfer, and increased conductivity vastly improved the catalytic activity. Remarkably, the optimal of N-CDs/NiO composite requires the overpotential of only 380 mV at a current density of 10 mA cm− 2 and a relatively low Tafel slope of 57.96 mV dec− 1 compared with pure NiO. These results open up a facile route for the application of N-CDs and offer prospects for CD-metal hybrids as high OER catalysts in electrochemical energy devices.

The carbon spheres (CSs) synthesized by an ultrasonic-spray pyrolysis method were activated for supercapacitor electrode. There are plenty of cracks on the surface of the activated carbon spheres (ACSs), which expend with increasing the activation temperature and activator dosage. The specific capacitance of ACSs increases with the activation temperature and activator dosage and reach to maximal value at certain conditions. Importantly, the ACS sample activated at relatively low activation temperature (600 °C) and 7 of mass ratio of KOH to CSs has the highest specific capacitance (about 209 F g− 1 at 50 mA g− 1 of current density) and indicates the excellent cycling stability after 1000 consecutive charge–discharge cycles. Furthermore, the graphene sheets could be found in the samples that were activated at 1000 °C. And the electrode prepared by the sample has the very low series resistance because of the excellent conductivity of the formed graphene sheets.

In the past few years, the Chinese government has put the internationalization of CNY on the map. Besides regular reforms such as facilitating CNY trading settlement and relaxing capital accounts, China deployed the Pilot Free Trade Zone and the One Belt One Road policy to significantly expand investment channels for CNY. It was also considered as a response to the criticism of CNY’s trade-driven model. CNY was developing from a trade currency to an investment currency and now has the potential to be a global reserve currency. The growth of CNY as an international currency could counterbalance the US dollardominated system and contribute to regional and international financial constancy. However, CNY internationalization is a double-edged sword. Inflow surges or disruptive outflows of capitals can give rise to macroeconomic fluctuation. With regard to the potential risks, it is suggested that Chinese authorities adopt more market-based measures and make the best of the international arrangements to protect the domestic financial integrity and stability.

While it was found that consumers’ experience on purchase intention is significantly affected by greater involvement in blogging (Hsu & Tsou, 2011), not many fashion companies use blogs to improve online consumption and relationship with their employee or customer (Fieseler & Fleck, 2013). Further, despite the growing significance of blog communication, there is a lack of understanding for the impact of accumulation of social capital in the blogosphere on the consumers’ attitude and engagement in previous research. This study is designed to address this gap, and particularly the role of three dimensions of social capital (i.e., structural, relational, and cognitive) in understanding blog user’s attitude and engagement. The purpose of this study is to investigate 1) the effect of blog user’s motivation (i.e., perceived usefulness, perceived ease of use, reputation, altruism, enjoyment, community identification) on their level of social capital within the blog 2) the influence of structural social capital and cognitive social on user’s relational social capital and 3) the impact of relational social capital on blog user’s attitude and engagement. Data was collected through a marketing research firm utilizing online survey method. With 530 usable data, the results of this study indicated enjoyment have positive significant effect on structural social capital while community identification have negative significant effect on structural social capital. For the effect of blogging motivation on cognitive social capital, the result showed positive significant effect of perceived usefulness, altruism and community identification on cognitive social capital Further, structural social capital does not have relationship with relational social capital while cognitive social capital has significant effect on relational social capital. The results also indicated that the relational social capital has influence on blogging attitude, which in turn has strong positive relationship with blogging engagement. The findings of this study contribute some useful knowledge about fashion blog and the relationships of the three social capital dimensions to the literature. Also, this study not only provides theoretical insight into understanding the influence of fashion blog user’s motivation on blogging behavior and satisfaction of needs of belong, it also exposes the influence of relationships building in blog community on user’s blogging attitude and engagement. Previous studies focused more on social influence on knowledge sharing motivation, and most of the researchers paid attention to the interaction of cognitive social capital and relational capital. This study employs the knowledge sharing motivation findings of previous studies, and it uses the effective motivation factors to test if they have the same impacts on people’s blogging behavior.

Due to the continuous development of international retailers in the Chinese market, and the merger and reorganization among Chinese retailers in recent years, the degree of concentration of the Chinese retail industry has been increasing, and the scale of retailers has been expanding. It is suggested by the report China Powers of Retailing 2014 that an increasing number of large-scale retail groups have been formed in the Chinese retail industry. In large and medium-sized cities in China, such large-scale supermarkets as Wal-Mart, Carrefour and RT-Mart have controlled most market shares of food and daily necessities. And large-scale household appliance chains, such as Gome and Suning, have controlled most market shares of home appliance. Due to the advantage of scale and brand of large-scale retailers, these retailers have gradually occupied a leading role in the supply chain, and formed buyer monopoly power and countervailing power. Intuitively speaking, retailers can acquire obvious advantages in procurement activities, no matter it is the buyer monopoly power or countervailing power that is being utilized. And the advantages are beneficial to the improvement of retailers’ procurement performance. However, it is pointed out by a number of scholars’ research that buyer power’s influence on retail enterprises’ performance is quite complicated. Whether buyer power can improve economic efficiency depends on the quality of retailer-supplier relationship. The quality of the relationships between retailers and suppliers exerts direct influence on the stability, durability and equity of the trade. In the long term, the reinforcement of buyer power will probably exert adverse influence on the suppliers and retailers. By imposing influence on suppliers with buyer power, retailers will cause twisted competition and prifit shrinkage to suppliers in the upstream market. As a result, the quantity of suppliers will be decreased, which will be disadvantageous to the selection of retailers and affect retailers’ utilization of their negotiating advantage. In the meanwhile, by imposing special prices and discounts, collecting extra charges and signing exclusive agreement with suppliers, retailers will lead to suppliers’ impaired benefit. It will further affect the quality of the retailer-supplierrelationship and ultimately exert adverse influence on both parties’ long-term earnings. In the existing research, few scholars have thoroughly discussed the influence of retailers’ buyer power on the quality of retailer-supplier relationship and retail enterprises’ procurement performance. In addition, different conclusions exist in the analysis of the relationships among the three factors, or between two of them. In order to empirically test the influence of retailers’ buyer power on the quality of retailer-supplier relationship and retail enterprises’ procurement performance, we established the theoretical model of this study in figure 1. The research will help us to cognize the influence of retailers’ buyer power more reasonably, and guide retailers better utilize buyer power, an attempt is made to explore the following questions in this research: 1. Does direct positive influence exist between large-scale retailers’ buyer power and retailers’ procurement performance? 2. Are there any differences in the influence of different types of retailers’ buyer power on retailers’ procurement performance? 3. What influence will large-scale retailers’ buyer power exert on the quality of retailer-supplier relationship? 4. When the quality of retailer-supplier relationship is brought in as a mediating variable, what influence will large-scale retailers’ buyer power exert on retailers’ procurement performance? From the perspective of the relationships among channel members, large-scale retailers in the Chinese market, such as Wal-Mart, Carrefour, RT-Mart, OUYA Supermarket and Vanguard, as well as suppliers of their products are taken as the object of the research. Methods like interview, pre-survey and official survery with questionnaire are adopted to verify different hypotheses in the research. During the indepth interview, twelve respondents are invited respectively to the interview. Seven of them are in charge of large-scale retailers’ procurement, and five of them are salespersons of manufacturers, who supply products to retailers. It can be seen from the result of the interview that the twelve respondents hold different opinions towards the relationships among large-scale retailers’ buyer power, the quality of retailer-supplier relationship and retailers’ procurement performance. In terms of the influence of large-scale retailers’ buyer power on retailers’ procurement performance, some believe that there’s positive influence, some believe there’s negative influence, and some believe the influence should be respectively analyzed according to the degree of buyer power. In terms of the influence of large-scale retailers’ buyer power on the quality of retailer-supplier relationship, some believe large-scale retailers’ buyer power exerts positive influence on the quality of retailer-supplier relationship, some believe it exerts negative influence, and some believe the influence depends on specific circumstances. During the pre-survey with questionnaire, scales of retailers’ buyer power, the quality of retailer-supplier relationship and retailers’ procurement performance are developed on the basis of theoretical overview and interview research. Specifically speaking, the scale of retailers’ buyer power is constituted of two level-1 dimensions (buyer’s monopoly power and countervailing power) and seven level-2 dimensions; the scalerelationship and ultimately exert adverse influence on both parties’ long-term earnings. In the existing research, few scholars have thoroughly discussed the influence of retailers’ buyer power on the quality of retailer-supplier relationship and retail enterprises’ procurement performance. In addition, different conclusions exist in the analysis of the relationships among the three factors, or between two of them. In order to empirically test the influence of retailers’ buyer power on the quality of retailer-supplier relationship and retail enterprises’ procurement performance, we established the theoretical model of this study in figure 1. The research will help us to cognize the influence of retailers’ buyer power more reasonably, and guide retailers better utilize buyer power, an attempt is made to explore the following questions in this research: 1.

During the pre-survey with questionnaire, scales of retailers’ buyer power, the quality of retailer-supplier relationship and retailers’ procurement performance are developed on the basis of theoretical overview and interview research. Specifically speaking, the scale of retailers’ buyer power is constituted of two level-1 dimensions (buyer’s monopoly power and countervailing power) and seven level-2 dimensions; the scaleof the quality of retailer-supplier relationship is constituted of three level-1 dimensions (cooperation, adaption and relationship atmosphere); the scale of retailers’ procurement performance is constituted of three level-1 dimensions (cost performance, time performance and quality performance of procurement). The questionnaire pre-survey is specific to retailers’ procurement staff and suppliers’ sales personnel respectively. A total of valid 179 questionnaires are collected, among which, 86 are from retailers’ procurement staff and 93 are from suppliers’ sales personnel. Based on the survey data, SPSS and AMOS software are utilized in the analysis of items, reliability and validity of the different scales. Finally, the factor structure of the scale regarding retailers’ buyer power is adjusted, and the scale regarding retailers’ buyer monolopy power is re-designed specially. During the official survey with questionnaire, questionnaires are handed out to retailers’ procurement staff and suppliers’ sales personnel respectively. A total of 340 valid questionnaires are collected, among which, 178 are from retailers’ procurement staff and 162 are from suppliers’ sales personnel. The samples, which are quite representative, are evenly distributed. Based on the survey data, SPSS and AMOS software are utilized to further analyze the reliability and validity of the different appraisal scales. Finally, the various hypotheses in the research are tested by causual steps of regression analysis with SPSS. After relatively complicated and elaborate statistical analysis, most of the hypotheses are supported, some are partially supported, and only one is not supported. One of the mediating effect analysis results is show in table 1 and figure 2. Based on direct regression analysis, we can get some important results: First of all, the hypothesis that retailers’ buyer power will overally exert positive influence on retailer enterprises’ procurement performance is supported, but the hypothesis that retailers’ buyer monopoly power and countervailing power will exert positive influence on retailer enterprises’ procurement performance is partially supported. Secondly, the hypothesis that retailers’ buyer power will overally exert negative influence on the quality of retailer-supplier relationship is not supported, and the hypothesis that retailers’ buyer monopoly power will exert negative influence on the quality of retailer-supplier relationship and the dimension is partially supported, and the hypothesis that retailers’ buyer countervailing power will exert positive influence on the quality of retailer-supplier relationship and the dimension is supported. Thirdly, the hypothesis that the quality of retailer-supplier relationship, as well as the dimensions (cooperation and relationship atmosphere) will overally exert positive influence on retailer enterprises’ procurement performance is supported, and the hypothesis that the dimension---the adaptation of the quality of retailer-supplier relationship will exert positive influence on retail enterprises’ procurement performance is only partially supported. Based on causual steps of regression analysis for the mediating effect, we can also get some important results: First of all, the relationship quality plays a complete intermediary role between the retailer’s buyer power and the procurement performance. Secondly, the relationship quality plays a complete intermediary role between the r retailers’ buyer monopoly power and the procurement performance. Thirdly, the relationship quality plays a complete intermediary role between the r retailers’ buyer countervailing power and the procurement performance.Some inspirations are achieved from the research. First of all, basically speaking, the direct influence of retailers’ buyer power on retail enterprises’ procurement performance is significantly positive. Secondly, the influence of retailers’ buyer power on the quality of retailer-supplier relationship is relatively complicated. Thirdly, basically speaking, the influence of the quality of retailer-supplier relationship on retail enterprises’ procurement performance is significantly positive. Fourthly, after the quality of retailer-supplier relationship is brought in as a mediating variable, the influence of retailers’ buyer power on retail enterprises’ procurement performance depends on the specific condition of the retailer-supplier relationship.

During the past few years, the Bank of Japan has injected billions of yen into the economy and pursued a monetary easing policy. Japan has plausible arguments, namely that its current policies are needed to support the growth of the economy and to spur inflation. However, these measures result in a weakened yen and increase trade imbalances between Japan and other Asian countries, particularly China. This article argues that Japan’s practice is rooted in protectionism and examines such actions under the IMF Agreement and the WTO system. It is suggested that the Chinese government should adopt diplomatic and judicial approaches to urge Japan to return to normal monetary policies.

Wood vinegar, an extract from Acer Tegmentosum Maximowicz, was evaluated for its hypoglycemic and anti-diabetic properties by using normal and diabetic rats. The extract was dissolved in water and administered daily for six or seven weeks. In experiment 1, thirty normal Sprague- Dawley (SD) male rats were randomly divided into five treatments of 6 rats each. The treatments were T1 (mineral water), T2 (mineral water), T3 (silver solution), T4 (wood vinegar), and T5 (silver solution + wood vinegar) and diabetes was induced by intravenous injection of streptozotocin except T1. In experiment 2, sixteen diabetic Goto-Kakizaki (GK) male rats were randomly divided into four treatments of 4 rats each. The treatments were T1 (mineral water), T2 (silver solution), T3 (wood vinegar), and T4 (silver solution + wood vinegar). Streptozotocin-induced diabetic rats showed less body weight gain, more food intake and less water consumption as compared with normal non-diabetic rats. Oral administration of wood vinegar resulted in more weight gain, lower blood glucose concentration and urine pH among all the diabetic rats. In experiment 2, diabetic GK rats administrated with wood vinegar showed higher weight gain, food intake and less water intake when compared with control. However, supplementation with wood vinegar did not result in any decrease of blood glucose concentrations. It could be concluded that wood vinegar extracted from Acer Tegmentosum Maximowicz exerted hypoglycemic effect in diabetic-induced normal rats, but not in diabetic GK rats.
