This study comprehensively investigates three types of graphite materials as potential anodes for potassium-ion batteries. Natural graphite, artificial carbon-coated graphite, and mesocarbon microbeads (MCMB) are examined for their structural characteristics and electrochemical performances. Structural analyses, including HRTEM, XRD, Raman spectroscopy, and laser particle size measurements, reveal distinct features in each graphite type. XRD spectra confirm that all graphites are composed of pure carbon, with high crystallinity and varying crystal sizes. Raman spectroscopy indicates differences in disorder levels, with artificial carbon-coated graphite exhibiting the highest disorder, attributed to its outer carbon coating. Ex-situ Raman and HRTEM techniques on the electrodes reveal their distinct electrochemical behaviors. MCMB stands out with superior stability and capacity retention during prolonged cycling, attributed to its unique spherical particle structure facilitating potassium-ion diffusion. The study suggests that MCMB holds promise for potassium-ion full batteries. In addition, artificial carbon-coated graphite, despite challenges in hindering potassium-ion diffusion, may find applications in commercial potassium-ion battery anodes with suitable coatings. The research contributes valuable insights into potassiumion battery anode materials, offering a significant extension to the current understanding of graphite-based electrode performance.

Amorphous molybdenum sulfide ( MoSx) has been regarded as a promising hydrogen evolution reaction (HER) catalyst due to its mild preparation conditions and low-cost precursor materials. In this work, we report a simple strategy combining the growth of amorphous MoSx on the surface of metal organic frameworks (ZIF-67) and annealing treatment to prepare Co-doped MoSx nanopolyhedrons (denoted as CoMoSx NPs). The CoMoSx NPs exhibit excellent HER activity in acid condition with an overpotential of 188 mV at a current density of 10 mA cm− 2 (η10), and a relatively stable overpotential after 2000 cyclic voltammetry (CV) cycles testing. The excellent HER performance of the CoMoSx NPs can be attributed to the doping of Co element adjust the electronic structure and increase the conductivity of catalyst, and the nanopolyhedrons structure which can expose more active sites for HER electrocatalytic. This study offers a low-cost and simple strategy to prepare high-activity HER catalyst, which holds great promises in developing advanced electrocatalysts for energy storage.

In recent years E-commerce platforms recommend some products for consumers based on their shopping history and user persona. However, sometimes, unfamiliar products or styles would be recommended to consumers unintentionally or intentionally. Curiosity drives consumers to try but this idea would be declined with the consideration of product fit uncertainty. Augmented Reality (AR) is the integration of digital information with the user‘s environment in real-time (Hilken et al. 2018), it can deal with issues related to physical apprehension that hinder consumers’ online shopping (i.e, clothes, cosmetics), especially for the unfamiliar style. This study aims to investigate whether AR technology could improve consumers' purchase likelihood. Augmented Reality (AR) can enhance customer experiences in a multichannel environment (Hilken et al. 2017). AR Integrates online experiences into the offline experience (Hilken et al. 2018), such as virtual try-on or magic mirrors. Customers often find it difficult to imagine how firms’ products and services fit them personally or fit with their environment (Hilken et al. 2018). Drawn on AR, consumers can easily evaluate the fitness between themselves and the selected products. Prior studies have explored the different underlying processes of why AR technology could improve consumer purchase intention and customer experience. For instance, according to the situated cognition theory, AR creates a feeling of spatial presence (Hilken et al. 2017). The usage of AR benefits mental imagery, improving decision comfort (Heller et al. 2019). AR can compensate for consumers’ need for touch and offer hedonic and/or utilitarian benefits (Gatter et al. 2022). Based on media richness theory, AR offers more information for customers (Hoffmann et al. 2022), which represents a fitting concept for customers to evaluate the product (Javornik 2016).

Social media began to boom in the 2000s. According to statistics, there are 92.3% of internet users are social media users who spend nearly two and a half hours daily on social media. Instagram is considered the most popular image-sharing platform, with more than 1.2 billion monthly active users. Meanwhile, consumers nowadays refer to and follow online reviews to assist their decision-making process more efficiently.

Biomass carbon materials with high rate capacity have great potential to boost supercapacitors with cost effective, fast charging– discharging performance and high safety requirements, yet currently suffers from a lack of targeted preparation methods. Here we propose a facile FeCl3 assisted hydrothermal carbonization strategy to prepare ultra-high rate biomass carbon from apple residues (ARs). In the preparation process, ARs were first hydrothermally carbonized into a porous precursor which embedded by Fe species, and then synchronously graphitized and activated to form biocarbon with a large special surface area (2159.3 m2 g− 1) and high degree of graphitization. The material exhibited a considerable specific capacitance of 297.5 F g− 1 at 0.5 A g− 1 and outstanding capacitance retention of 85.7% at 10 A g− 1 in 6 M KOH, and moreover, achieved an energy density of 16.2 Wh kg− 1 with the power density of 350.3 W kg− 1. After 8000 cycles, an initial capacitance of 95.2% was maintained. Our findings provide a new idea for boosting the rate capacity of carbon-based electrode materials.

To solve the problem of water pollution, researchers have proposed a photocatalytic degradation technology, in which the key factor is the development of efficient photocatalytic materials. Graphitic carbon nitride (g-C3N4), an n-type semiconductor, has been widely studied due to its suitable band gap (2.7 eV), low cost, easy preparation, non-toxicity, and high photostability. However, the pure-phase g-C3N4 still has defects such as low specific surface area, insufficient visible light absorption, low charge mobility, few active sites for interfacial reaction, and easy recombination of photogenerated electron–hole pairs, which leads to the lower photocatalytic activity of g-C3N4. Aiming at the problems mentioned above, this paper focus on the synthesis of g-C3N4-based composites with high photocatalytic activity via lemon juice induction method. Thiourea and lemon juice were selected as precursors, and carbon quantum dots (CQDs) as electron mediators were introduced anchoring on the surface of g-C3N4 to build g-C3N4/CQDs with compact interface. The results showed that small-sized CQDs are uniformly distributed on the surface of g-C3N4, and the g-C3N4/CQDs composite has a 2D0D structure, which reduces the recombination of photogenerated electron–hole pairs. The photocatalytic degradation efficiency of 4% g-C3N4/CQDs for RhB reaches the highest data of 90.9%, and the photocatalytic degradation rate is 0.016 min− 1, which is about 2.3 times that of g-C3N4. After four cycles of photocatalytic reaction, the photocatalytic degradation efficiency of the material remained at 81.7%. Therefore, the g-C3N4/CQDs synthesized via lemon juice induction has a more stable microstructure, and the charge separation efficiency is greatly improved, which is suitable for practical photocatalytic environmental protection.

In the molecular cloud G33.92+0.11A, massive stars are forming sequentially in dense cores, probably due to interaction with accreted gas. Cold dense gas, which is likely the pristine gas of the cloud, is traced by DCN line and dust continuum emission. Clear chemical differences were observed in different source locations and for different velocity components in the same line of sight. Several distinct gas components coexist in the cloud: the pristine cold gas, the accreted dense gas, and warm turbulent gas, in addition to the star-forming dense clumps. Filaments of accreted gas occur in the northern part of the A1 and A5 clumps, and the velocity gradient along these features suggests that the gas is falling toward the cloud and may have triggered the most recent star formation. The large concentration of turbulent gas in the A2 clump seems to have formed mainly through disturbances from the outside.

Introduction The social Web is becoming more and more visual. While Facebook remains the leading social networking site (SNS), visual-based platforms such as Instagram and Pinterest have showed a significant increase in the proportion of online users worldwide (Greenwood, Perrin, & Duggan, 2016; Statista, 2017; Pew Research Center, 2017). The trend toward visual communication on SNSs is influenced by the emergence of advanced mobile technologies and the shifting habits of how social media users consume content today. While images displayed on Instagram are past-oriented sharing of memories, or present-oriented displays of creativity, Pinterest presents opportunities for future-oriented inspiration to evolve (Jin, Lin, Gilbreath, & Lee, 2017; Phillips, Miller, & McQuarrie, 2014). Pinterest also serves as a searchable archive of visual content, allowing users to seek and include brand-relevant pins and boards into their own aspirations and inspirations, thus facilitating the sharing of branded content (Phillips et al., 2014). Extant industry reports also suggest that Pinterest users are more likely to image-search for products, interact with sponsored pins, and show favorable attitudes toward advertising, compared with Facebook or Twitter users (McMullen, 2015; Ruscillo, 2017; Williamson, 2015). Considering the benefits of social media for global marketing and the role that imagery plays for developing international brands (Mikhailitchenko, Javalgi, Mikhailitchenko, & Laroche, 2009), this research focuses on the visual aspects of consumer engagement with branded content on Pinterest and investigates how such engagement leads to consumer-brand relationship building and Pinterest-inspired purchase intention. Theoretical Frameworks The extant consumer research has documented the superiority effect of visual content on facilitating persuasion (Childers & Houston, 1984; Miniard, Bhatla, Lord, Dickson, & Rao, 1991). Recent research on social media marketing also suggests that branded content with visual elements help generate favorable consumer responses (De Vries, Gensler, & Leeflang, 2012; Trefzger, Baccarella, & Voigt, 2016). The presentation of branded posts is directly related to the flow construct and trust (Bart, Shankar, Sultan, & Urban, 2005; Hoffman & Novak, 1996). Along this logic, consumer engagement, the degree to which consumers consume, contribute, and create social media content in relation to brands (Schivinski, Christodoulides, & Dabrowski, 2016), is likely to be influenced by brand-related visual cues on Pinterest. While consumption refers to consumers’ acquisition of both brand-created and user-generated content (Muntinga, Moorman, & Smit, 2011), contribution refers to consumers’ inputs to content created by brands or by other consumers (Shao, 2009). Further, creation is the highest level of engagement, which refers to consumers’ generation of brand-related content that could stimulate further consumption and contribution (Muntinga et al., 2011). Therefore, the visually dominant and appealing presentation style, such as appearance, layout, and images, on Pinterest would provide users with high information content, and is likely to increase both active and passive consumer engagement with brands (Bart et al., 2005). Consumer engagement is then expected to encourage social media users’ willingness to actively promote and endorse brand-related content, including organic and sponsored pins. Such volunteer display of their preferred brand-related content is likely to help engender eWOM communication and make such content become more influential in the social Web (Chu & Kim, 2011). As a result, users’ brand-related Pinterest activities are likely to enhance their relationships with brands (Rapp, Beitelspacher, Grewal, & Hughes, 2013) and their intention to purchase from the brands featured in the pins and boards (King, Racherla, & Bush, 2014). All hypothesized relationships are therefore formulated and displayed in Figure 1. Methods To test the proposed conceptual model, an online survey was conducted with participants recruited from a consumer panel administrated by Qualtrics. A total of 467 Pinterest users (58.2% female, Mage = 28.9, SDage = 5.6) comprised the sample, including Caucasian (76%), African American (7.5%), Hispanic (7.4%), Asian (6.9%), multiracial (1.3%), and others (.9%). The participants spent an average of 9.5 hours on Pinterest per week. Smartphones (54.8%) emerged as the most dominant devices for their Pinterest usage, followed by computers (34.9%) and tablets (10.3%). They had an average of 33.7 boards (Range = 1,233), 1,384.1 Pins (Range = 69,000), 930.1 likes (Range = 100,000), 319.0 followers (Range = 44,231), 65.0 following topics (Range = 3,442), 173.0 following people (including brands, Range = 7,000), and 102.0 following boards (Range = 6,000). To note, 78.3% of the participants reported that they made Pinterest-inspired purchases frequently (including 24.8% always, 24.4% usually, and 29.1% often). In addition, the participants were asked to answer questions pertaining to their perceptions of visual cues related to a self-selected brand on Pinterest, engagement with brand-related content, brand endorsing behavior, consumer-brand relationships, and Pinterest-inspired purchase intention (see Table 1). Results To test the proposed hypotheses, a two-step modeling approach following Anderson and Gerbing’s (1988) procedures was employed. The results of confirmatory factor analysis (CFA) showed that the measurement model achieved acceptable fit for the data (χ2 = 1178.30, df = 393, χ2/df = 2.99, RMSEA = .065, SRMR = .054, CFI = .930, TLI = .922). The constructs had good composite reliability (>.70). Factor loadings of the construct indicators were all above .70 with significant t values, which indicated good convergent validity for each of the construct items (Nunnally & Bernstein, 1994). Following Fornell and Larcker’s (1981) criteria, the results achieved satisfactory discriminant validity because the average variance extracted (AVE) for each factor was above .50 and greater than the squared correlations between each pair of constructs. The factor scores were then used to perform a path analysis for hypothesis testing which showed satisfactory fit of the conceptual model (see Figure 2). The results indicated that visual cues positively influenced consumer engagement with brand-related content (β = .68, p < .001), which positively led to brand endorsing behavior (β = .86, p < .001). Consequently, brand endorsing behavior positively enhanced the development of consumer-brand relationships (β = .97, p < .001) and increased Pinterest-inspired purchase intention (β = .48, p < .001). In turn, all hypotheses were supported. Discussion and Conclusion In response to the thriving academic interests in understanding how social media users connect and interact with international brands across SNSs (Hennig-Thurau, et al., 2010), this research sheds light on factors that determine social media users’ active discovery, creation, and distribution of visual branded content and the effects of consumer engagement on social media marketing outcomes. By focusing on Pinterest, the research findings showed that users, both men and women, actively seek inspiration from Pinterest across brand-relevant categories. They are highly engaged, open to brand activities, and ready to take Pinterest-inspired actions in the real world. The visual presentation of branded content plays an important role in generating consumer engagement, which is likely to act as a form of perceived relationship investment and subsequently stimulates brand endorsing and advocacy behavior (Simon & Tossan, 2018). Engaged Pinterest users search and select brand-relevant visual content, including sponsored pins, as part of their self-presentation to others (Phillips et al., 2014). Through such interactions with brands and other like-minded users on the platform, their relationships with brands and purchasing behavior are likely to be further enhanced. This research integrates several important literature streams in the conceptual model and employs a representative adult sample to provide theory-driven and generalizable insights into how visually-focused social media marketing works. Marketing managers face opportunities and challenges that social media and the interconnected international business environment present. Therefore, it is crucial to understand how social media users interact with brands on different platforms in order to tailoring brand strategies accordingly for fostering consumer engagement. Specifically, as Pinterest’s popular visual discovery engine continues to attract myriads of global users, managers should harness the power of visual content marketing and engage current as well as potential consumers on the platform, which could have a significant impact on consumer-brand relationship building and business performance in domestic and foreign markets. Building on the findings of this research, future studies should further delve into the psychological underpinnings and motivations that drive consumer engagement with visual branded content on SNSs across cultures and discover how paid, owned and earned brand communication on visual-based SNSs can help strengthen consumer-brand relationships.

Soybean straw (SS)-based activated carbon was employed as a precursor to prepare carbon molecular sieves (CMSs) via chemical vapor deposition (CVD) technique using methane as carbon source. Prior to the CVD process, SS was activated by 0.5 wt% ZnCl2, followed by a carbonization at 500°C for 1 h in N2 atmosphere. N2 (77 K) adsorption-desorption and CO2 (273 K) adsorption tests were carried out to analyze the pore structure of the prepared CMSs. The results show that increasing the deposition temperature, time or methane flow rate leads the decrease in N2 adsorption capacity, micropore volume and average pore diameter of CMSs. The adsorption selectivity coefficient of CO2/CH4 achieves as high as 20.8 over CMSs obtained under the methane flow rate of 30 mL min–1 at 800°C for 70 min. The study demonstrates the prepared CMSs are a candidate adsorbent for CO2/CH4 separation.

The present paper discusses the interrelationship among knowledge creation, heterogeneity, and open service innovation – an important theme of marketing research. Drawing on the literature of knowledge based innovation, we argue that both researchers and practitioners should extend the functionality of created knowledge into open and service-oriented innovation context. Our conceptual framework represent the following major points. First, the four classic knowledge creation mode each has different influences on open service innovation, given employee and customer knowledge is a cornerstone of service innovation. Specifically, socialization positively, externalization positively, combination positively, and internalization negatively predicts open service innovation. Second, knowledge heterogeneity moderates in the above mentioned relationships. Implication are discussed

Lentinula edodes is an important cultivated mushroom in China. The development of Lentinula edodes production promotes more studies on it. In our previous work, degenerate PCR and chromosome walking technologies were used to obtain one pheromone receptor gene and one pheromone precursor gene from Lentinula edodes. In this study, four pairs of specific primers were designed according to the whole genome sequencing of the protoplast monokaryon of Lentinula edodes strain 135, to amplify STE3-like pheromone receptor gene and its flanking conserved genes in the protoplast monokaryon strain SUP2 derived from Lentinula edodes strain Suxiang and 33655bp DNA sequence was obtained. By BlastX search, seven putative genes were identified, and three of them are pheromone receptor encoded genes. Furthermore, near to two pheromone receptor genes, four genes encoding proteins with conserved motifs of pheromone precursors were found. This study firstly reveals the molecular organization of the B mating type locus of Lentinula edodes.

Web 2.0 communities are providing new opportunities for teachers’ professional development by supporting more flexible sharing, communicating, and collaborating among teachers at a distance. Meanwhile, literature concerning teachers’ professional development increasingly places value on communities of practice and web-based learning communities. This paper presents a case study on the design of teacher training supported by a Web 2.0 community. The training program discussed in the paper is characterized by employing peer-coaching to facilitate teachers’ learning in a Web 2.0 community, and is a part of a project funded by the Ford Foundation. The paper gives a brief introduction to the training program, and reports some important findings and reflections on design and practice for in-service teacher training. It includes the theoretical framework design, a training model as well as activity design, and the implementation and evaluation of the training program and useful experiences. Initially, taking account school teachers’ needs at the K12 level for curriculum reform and quality education, theory, knowledge and practice competences for learner-centered instruction were examined by using peer-coaching methods supported by online communities. The suggested training program was delivered in two Chinese districts in August 2009: Tianhe district of Guangzhou, and Wuhou district of Chengdu. More than 120 participants, including subject teachers, school principals and local teaching researchers, took part in the f2f training, online activities and the further practice activities. Even still on-going, the comprehensive investigation and evaluation of the training program explains that the initial results and observations collected during the process of training are very positive. With cause for optimism as to the prospect of achieving the training program’s goals, the study has demonstrated that a task-driven approach and peer-coaching supported by a web 2.0 community are effective methods for in-service teacher training, and that peer-coaching can be greatly extended by out-of-school activities.

Ingestion of plant secondary metabolites (PSMs) presents a major challenge to mammalian herbivores. We investigated the relationship between PSM concentrations in the diet and feeding patterns in sheep fed diet containing flavone extracted from Apocynum venetum. Results showed that the flavone concentrations significantly influenced food intake by sheep. With the concentration of flavone in diet increase, sheep can regulate their intake of PSM within limits that are tolerable.
