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.

Graphite felt is a felt-like porous material made of high-temperature carbonized polymers. It is widely used in electrode materials because of its good temperature resistance, corrosion resistance, large surface area and excellent electrical conductivity. In this paper, the surface functional group modification is of graphite felt electrodes (mainly nitrogen doping modification, nitrogen–sulfur or nitrogen–boron co-doping modification) and surface catalytic modification (metal/ion surface modification and metal oxide surface modification as Main). There are two main methods and research progresses to improve the performance of graphite felt electrodes, and the comprehensive performance of surface functional group-modified graphite felt electrodes and surface catalytically modified graphite felt electrodes are compared respectively. The results show that both surface functional group modification and surface catalytic modification can improve the comprehensive performance of graphite felt electrodes. In this paper, the future development direction of graphite felt activation modification is also prospected.

The purpose of this research is to explore the factors that affect a celebrity’s perceived authenticity on social media sites. In total, 653 Taiwanese consumers were recruited to examine the proposed model. The findings generally support our model. The theoretical and managerial implications of this study 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.

Transient luminous events (TLEs; sprites, elves, jets and etc.) are lightning-related optical flashes occurring above thunderstorms. Since the first discovery of sprites in 1989, scientists have learned a great deal about the morphological, spectroscopic and electromagnetic characteristics of TLEs through ground and spacecraft campaigns. However, most of the TLE studies were based on events recorded over US High Plains. To elucidate the possible biasing effects, space-borne observations are needed and have their merits. Imager of sprites and Upper Atmospheric Lightning (ISUAL) on the FORMOSAT-2 satellite is the first instrument to carry out a true global measurement of TLEs from a low- earth orbit. In this short paper, we apply a common astronomical data analysis technique, two-color diagram, on the ISUAL spectrophotometer (SP) data. By choosing appropriated bandpasses and converting the measured flux of TLEs into the unit of magnitude, two-color diagrams of TLEs can be constructed. We demonstrate that two-color diagrams, which were constructed from the narrow-band spectrophotometer data, can be used to classify different types of TLEs and trace their temporal evolution. The amount of reddening due to Earth's atmosphere can also be estimated from two-color diagrams assembled from the broad-band spectrophotometer data.

Purpose: This study aimed at exploring the product choice tendency differences between the consciousness and unconsciousness of goal orientation when product attributes is perceived to be compatible with the goal orientation. Research design, data and methodology: Empirical study used a 2 (goal conscious vs. unconscious) × 3 (hedonic vs. performance vs. reliability attribute) between-subjects design and one control group. To verify hypotheses, χ²-test was conducted to 320 questionnaire data answered by undergraduate students of Jiangxi Normal University in China. Results: First, consumers under unconscious condition showed a higher product choice consistency based on compatibility between hedonic (performance) attribute of the product and their hedonic (performance) promotion goal-orientation than those under the conscious condition. Second, product choice effects of compatibility between reliability attribute of the product and prevention goal orientation were not significantly different between consumers’ consciousness and unconsciousness of their prevention goal orientation. Conclusions: Marketers of ‘under dog’ should try to develop and deliver the product attributes different from the attributes of ‘top dog.’ And the ‘top dog’ marketers should help their customers to avoid the conflicts by developing the environment of inducing their goal orientation unconsciously. Brand marketers should always pay attention to the reliability attributes concerned with the prevention goal orientation.

Compared with the research on consumer engagement in brand community, the research on consumer engagement in brand public has been relatively less. This research aimed at exploring how brand public characteristics such as information variety, various communications and no limitation in expressing self affect the brand public engagement. 274 questionnaires answered by Chinese consumers are used to conduct analysis. Principal component analysis is used to test the reliability and validity of each construct, and structural equation model is used to test hypotheses. The study finds the positive effects of information variety on information benefits, those of various communications on social benefits, and also positive roles of no limitation in expressing self to brand-related self-expression motivation. And each of the information benefits, social benefits and brand-related self-expression motivation is proved to positively affect brand public engagement. The study implies that marketers should give attention to characteristics of brand public, and provide the ways by which members of brand public engage the brand. Additionally, marketers should pay more attention to both direct and indirect engagement activities of consumers toward brand public in social media to better understand their target consumers.

Purpose - This paper aims at exploring the effects of failure types such as failure in promotion orientation and failure in prevention orientation on consumers' consumption behavior, and the moderation role of lay theories in the effects. Research design, data, and methodology – This study employed 2 between-subject designs(failure in promotion orientation vs. failure in prevention orientation) and also 2 (failure in promotion orientation vs. failure in prevention orientation) with implicit self as the within-subject. Chinese consumers participated in the empirical study, and to verify the hypotheses ANOVA, T-test and regression analysis were used. Results – Consumers were more likely to choose adaptive consumption behavior rather than compensatory consumption behavior when they were encountered with failure in promotion orientation versus failure in prevention orientation. Lay theories did play the moderation role in the effect of failure types on consumption behavior. The incremental theorists who think that effort is an important way to accomplish their learning goals showed more willingness to conduct compensatory consumption behavior rather than adaptive consumption behavior. Conclusions – Marketers should put more attention on the ways by which their products can help consumers self-improve when consumers encounter with failure. They should also be aware of the importance of consumers' mindsets when designing and developing advertising messages.
