The rationally structural engineering is an efficient strategy to improve the comprehensive performance of potassium‐ion storage anode materials. In this paper, a hybrid with hollow FeS2 nanoparticles anchored into the 3D carbon skeleton (labeled as H‐FeS2@3DCS) is successfully constructed through two critical steps of in situ chemical deposition and anion‐exchange reaction strategies. In the former, the water‐soluble Na2CO3 crystals are used as hard templates for the preparation of 3DCS, while Fe3+‐containing aqueous solutions are utilized to remove the Na2CO3 templates. Interestingly, the intense collision between Fe3+ and CO32‐ in aqueous solution produces nanoscale Fe(OH)3 colloidal particles, which are firmly anchored into the pores of the carbon skeleton to form a "lotus‐seed"‐like nanostructure. In the latter case, a central void space is created inside the FeS2 nanoparticles due to the different diffusion rates of S‐anions and Fe‐cations during the subsequent sulfidation process. Thanks to this unique composition model, the H‐FeS2@3DCS hybrid not only alleviates the volume expansion efficiently by rationally hollow structure design, but also provides spacious "roads" (3D carbon skeleton) and "houses" (hollow FeS2 nanoparticles) for fast K‐ion transition and storage. As the anode of PIBs and PIHCs, the resultant H‐FeS2@3DCS electrode delivers an obviously enhanced K‐ions storage performance over state‐of‐the‐art. [ABSTRACT FROM AUTHOR]

AbstractIn the post-pandemic era, tourists are increasingly interested in sustainable consumption, particularly focusing on green hotels. Given the ongoing endemic nature of COVID-19, our research explores the effects of tourists’ residential locations, specifically pandemic-affected areas, on their intention to choose green hotels. Drawing on the Protection Motivation Theory, we discuss how and why residential location influences risk perception, which in turn motivates tourists to contribute to environmental protection by opting for green hotels. Results from five experiments suggest that the influence of pandemic areas on green hotel consumption can fluctuate over time. During the initial outbreak, a positive correlation emerges between tourists’ risk perception and their distance from the pandemic’s epicenter. Those residing in marginal areas show greater threat appraisal and stronger intentions toward choosing green hotels than tourists in central areas. However, this relationship is found to reverse during the mitigation and post-pandemic phases. Furthermore, our research reveals that hotels can significantly sway tourists toward green consumption through the strategic use of hope or fear appeals in advertising. These findings enrich the literature on pandemic-related influences on green consumption and offer practical insights for hotel managers and policymakers seeking to promote sustainable travel more effectively in the post-pandemic era.

Template‐assistant design and fabrication of porous carbon electrode materials has experienced great progress throughout the past decades and yielded lots of successes via various gas or solid state templates. Nevertheless, liquid‐state templates are rather rare in preparing porous carbon materials to date. In this work, melting B2O3 beads are used as both templates and a B dopant, leading to unique B, N co‐doping hierarchically porous carbons containing a "bubble pool"‐like skeleton built of interconnected carbon nanobubbles. Notably, an interesting amending effect of doped B atoms on the N‐doped carbon network can be identified for the first time, which creates a "paddy field"‐like hybrid microstructure with the co‐existence of sp2 short‐range order and sp3 defective areas, leading to an ideal model of carbon materials with both good conductivity and high capacity. Together with the rich ion diffusing pathways and the structural integrity of the "bubble pool"‐like skeleton, the resultant electrode delivers a comprehensive K‐ion storage performance. Therefore, the findings demonstrate the unique pore‐making merits of liquid state templates, which may open the door for exploring porous carbons with more innovations of microstructures and functionalities for applications in energy storage and other fields.

Many studies highlight the merits of positive reviews on social networking sites (SNSs), suggesting that consumers tend to consider these to be trustworthy recommendations. This study draws attention to the potential negative effects of luxury hotels' positive reviews on SNSs. We propose that positive reviews may encourage social comparison and trigger feelings of malicious envy, thereby negatively influencing purchase intentions. Results from two experiments show that high similarity between the review writer and readers increases readers' social comparison tendency, which induces malicious envy when the writer is considered undeserving of luxury hotel consumption. This leads to decreased purchase intentions toward the hotel brand mentioned in the review and increased purchase intentions toward competing hotel brands. The findings have implications for buzz marketing strategies seeking to mitigate the risk of eliciting malicious envy on SNSs. [ABSTRACT FROM AUTHOR]

The large volume expansion induced by K+ intercalation is always a big challenge for designing high‐performance electrode materials in potassium‐ion storage system. Based on the idea that large‐sized ions should accommodate big "houses," a facile‐induced growth strategy is proposed to achieve the self‐loading of MoS2 clusters inside a hollow tubular carbon skeleton (HTCS). Meantime, a step‐by‐step intercalation technology is employed to tune the interlayer distance and the layer number of MoS2. Based on the above, the ED‐MoS2@CT hybrids are achieved by self‐loading and anchoring the well‐dispersed ultrathin MoS2 nanosheets on the inner surface of HTCSs. This unique compositing model not only alleviates the mechanical strain efficiently, but also provides spacious "roads" (hollow tubular carbon skeleton) and "houses" (interlayer expanded ultrathin MoS2 sheets) for fast K+ transition and storage. As an anode of potassium‐ion batteries, the resultant ED‐MoS2@CT electrode delivers a high specific capacity of 148.5 mAh g−1 at 2 A g−1 after 10 000 cycles with only 0.002% fading per cycle. The assembled ED‐MoS2@CT//PC potassium‐ion hybrid supercapacitor device shows a high energy density of 148 Wh kg−1 at a power density of 965 W kg−1, which is comparable to that of lithium‐ion hybrid supercapacitors.

With the rapid development of artificial intelligence, information system, and mobile technologies, some companies (e.g. airlines) consider fully replacing service employees with self-service technologies (SSTs) to cut down costs and to increase efficiency. However, replacing full services with SSTs sometimes fail to deliver the benefits companies have hoped for: users may feel that they are being forced to use SSTs and show resistance to the new technologies. To investigate why users show resistance, we draw inferences from psychological reactance theory and argue that users may perceive the forced adoption as a threat, which leads to resistance of SSTs. A conceptual model was developed and an empirical study was conducted. The results show that, under a forced situation, users are likely to perceive the forced adoption as a threat to their freedom, causing them to have negative emotions and perceptions towards the SSTs, and, in turn, their adoption intention decreases and switch intention increases. The findings provide insights on why users show resistance to SSTs and highlight the impacts of the motivational state of psychological reactance. [ABSTRACT FROM AUTHOR]

Soil organic carbon (SOC) can be defined by measurable chemical and physical pools, such as mineral-associated carbon, carbon physically entrapped in aggregates, dissolved carbon, and fragments of plant detritus. Yet, most soil models use conceptual rather than measurable SOC pools. What would the traditional pool-based soil model look like if it were built today, reflecting the latest understanding of biological, chemical, and physical transformations in soils? We propose a conceptual model-the Millennial model-that defines pools as measurable entities. First, we discuss relevant pool definitions conceptually and in terms of the measurements that can be used to quantify pool size, formation, and destabilization. Then, we develop a numerical model following the Millennial model conceptual framework to evaluate against the Century model, a widely-used standard for estimating SOC stocks across space and through time. The Millennial model predicts qualitatively similar changes in total SOC in response to single factor perturbations when compared to Century, but different responses to multiple factor perturbations. We review important conceptual and behavioral differences between the Millennial and Century modeling approaches, and the field and lab measurements needed to constrain parameter values. We propose the Millennial model as a simple but comprehensive framework to model SOC pools and guide measurements for further model development. [ABSTRACT FROM AUTHOR]

Unprecedented levels of nitrogen (N) have been deposited in ecosystems over the past century, which is expected to have cascading effects on microbially mediated soil respiration ( SR). Extracellular enzymes play critical roles on the degradation of soil organic matter, and measurements of their activities are potentially useful indicators of SR. The links between soil extracellular enzymatic activities ( EEAs) and SR under N addition, however, have not been established. We therefore conducted a meta-analysis from 62 publications to synthesize the responses of soil EEAs and SR to elevated N. Nitrogen addition significantly increased glycosidase activity ( GA) by 13.0%, α-1,4-glucosidase ( AG) by 19.6%, β-1,4-glucosidase ( BG) by 11.1%, β-1,4-xylosidase ( BX) by 21.9% and β-D-cellobiosidase ( CBH) by 12.6%. Increases in GA were more evident for long duration, high rate, organic and mixed N addition (combination of organic and inorganic N addition), as well as for studies from farmland. The response ratios ( RRs) of GA were positively correlated with the SR- RRs, even when evaluated individually for AG, BG, BX and CBH. This positive correlation between GA- RR and SR- RR was maintained for most types of vegetation and soil as well as for different methods of N addition. Our results provide the first evidence that GA is linked to SR under N addition over a range of ecosystems and highlight the need for further studies on the response of other soil EEAs to various global change factors and their implications for ecosystem functions.

Advertising can be used to promote tourism recovery post-COVID-19 pandemic. However, the effectiveness of such advertising in the pandemic context remains uncertain. This study shows that when a country is associated with a warmth stereotype, advertisements with emotional appeals increase visit intention, whereas advertisements with rational appeals are more effective when the country is associated with a competence stereotype. These relationships are mediated by processing fluency and strengthened when the perceived health risk at a destination is low. Our study enriches tourism research by revealing that the effectiveness of destination advertising depends on a combination of tourists' pre-established country stereotypes, destination marketing organizations' advertising messages, and the pandemic environment. It also introduces metacognition as a new mechanism underlying travel decisions. • For a country with a warmth stereotype, emotional appeal increases tourists visit intention. • For a country with a competence stereotype, rational appeal increases tourists visit intention. • Processing fluency mediates the congruence effect of country stereotype and message appeal. • The congruence effect is stronger when tourists perceived a low level of health risk.
