All-solid-state lithium batteries (ASSLBs) have advantages of safety and high energy density, and they are expected to become the next generation of energy storage devices. Sulfide-based solid-state electrolytes (SSEs) with high ionic conductivity and low grain boundary resistance exhibit remarkable practical application. However, the space charge layer (SCL) effect and high interfacial resistance caused by a mismatch with the current commercial oxide cathodes restrict the development of sulfide SSEs and ASSLBs. This review summarizes the research progress on the SCL effect of sulfide SSEs and oxide cathodes, including the mechanism and direct evidence from high performance in-situ characterizations, as well as recent progress on the interfacial modification strategies to alleviate the SCL effect. This study provides future direction to stabilize the high performance sulfide-based solid electrolyte/oxide cathode interface for state-of-the-art ASSLBs and future all-SSE storage devices.

为了避免老、少、边地区因经济相对落后、科技条件艰苦和信息相对闭塞而造成科技人员流失，促进不发达地区的科技发展，国家自然科学基金委员会采取了设立地区科学基金的措施。这一明智而科学的措施对于稳定和培养西部边疆地区的科技人才队伍、提高地区科技水平、发展地方经济的作用是深远的，其影响力也是其他类型的项目所无法比拟的，但在有关资助工作中也存在一些问题值得我们思考。  相似文献   

International brand alliances and co-branding: antecedents of cognitive dissonance and student satisfaction with co-branded higher education programs     

Stephen Wilkins  Muhammad Mohsin Butt  Troy Heffernan 《Journal of Marketing for HIGHER EDUCATION》2018,28(1):32-50

The study investigates how in international partnerships the brand credibility of each partner, student-institution identification with each partner, and perceived service quality relate to student satisfaction. A structured survey questionnaire was completed by 528 students taking a co-branded higher education program in Hong Kong or Sri Lanka. The results indicate that the brand credibility of a foreign institution is a stronger influencer on student identification with the foreign institution as compared to the relationship between credibility and identification with the local partner. The negative relationship between organizational identification and cognitive dissonance for each institution in the partnership is also stronger for the foreign institution. As the popularity of international partnerships and co-branded higher education programs continues to grow, the importance and dominance of foreign brand credibility and student identification with foreign institutions is recognized.  相似文献   

Perceived service quality-loyalty path: A PAKSERV based investigation of international students enrolled in business schools in Thailand     

Muhammad Kashif  Pimpa Cheewakrakokbit 《Journal of Marketing for HIGHER EDUCATION》2018,28(1):51-65

We aim to examine the international student perceived service quality of Business Schools located in Thailand to link it with their intentions to remain loyal. The survey based approach is adopted to collect data from 300 international students enrolled in various business schools in Thailand. All the dimensions of PAKSERV except Personalization are found to positively contribute to student satisfaction, which strongly leads to their loyalty to business schools. This is the first study which validates the PAKSERV scale in a business school context while collecting data from international students – investigating their perceptions of service quality to link it to their loyalty to business schools. The findings call for investment in faculty and process development to improve the international student perceptions of business schools located in Thailand. The findings will help Thai higher education policymakers specifically to improve student perceived service quality in order to attract and retain international students.  相似文献

Exploring the role of a government authority in managing transformation in service re-engineering – Experiences from Dubai police

E-Government adoption and implementation has gained noticeable momentum across many developed and developing economies. Nevertheless, transitioning from the “electronic” to the stage of “transformational” domain – coined as t-Government – is posing the greatest challenge of how government services respond to changes in the broader economy and society. Despite considerable investments and the wide use of Information and Communications Technology (ICT), research literature on e-Government suggests that government services have yet to reach the full potential of seamless integration, where all transactions are completed electronically. Through a detailed analysis of the extant e-Government literature and a case study based empirical research, this paper explores the domain of e-Government in identifying the possible reasons for this potential shortfall in achieving full integration. Furthermore, the paper intends to highlight an aspect of complexity surrounding crossing the integration gap as the authors denote by “eChasm” in the e-Government conceptual model that leads to transformation. In addition, it focuses on radical change through Business Process Re-engineering (BPR) and the call for strategic style of leadership, for cross-agency collaboration leading to a successful realisation of transformational government (t-Government). It is interesting to note that researchers and public sector leaders have started to realise that implementing and managing the transformation of public services, copiously satisfying the users and stakeholders, is a task of multi-dimensional complexity.  相似文献   

Extraction of DNA suitable for PCR applications from mature leaves of Mangifera indica L.     

Muhammad Abubakkar Azmat  Iqrar Ahmad Khan  Hafiza Masooma Naseer Cheema  Ishtiaq Ahmad Rajwana  Ahmad Sattar Khan  Asif Ali Khan 《Journal of Zhejiang University. Science. B》2012,13(4):239-243

Good quality deoxyribonucleic acid (DNA) is the pre-requisite for its downstream applications. The presence of high concentrations of polysaccharides, polyphenols, proteins, and other secondary me- tabolites in mango leaves poses problem in getting good quality DNA fit for polymerase chain reaction (PCR) applications. The problem is exacerbated when DNA is extracted from mature mango leaves. A reliable and modified protocol based on the cetyl- trimethylammonium bromide (CTAB) method for DNA extraction from mature mango leaves is described here. High concentrations of inert salt were used to remove polysaccharides; Polyvinylpyrrolidone (PVP) and β-mercaptoethanol were employed to manage phenolic compounds. Extended chloroform-isoamyl alcohol treatment followed by RNase treatment yielded 950?1050 μg of good quality DNA, free of protein and RNA. The problems of DNA degradation,contamination, and low yield due to irreversible binding of phenolic compounds and coprecipitation of polysaccharides with DNA were avoided by this method. The DNA isolated by the modified method showed good PCR amplification using simple se- quence repeat (SSR) primers. This modified protocol can also be used to extract DNA from other woody plants having similar problems.  相似文献

Swayed by the logo and name: does university branding work?     

Muhammad Zaffwan Idris 《Journal of Marketing for HIGHER EDUCATION》2014,24(1):41-58

Over the last decade, many universities attempted to improve their public image by changing their corporate visual identity (CVI) and/or name. Despite the prevalence of such practices, little research has been conducted into their effectiveness. The research reported here focused upon one facet of the higher education branding debate, that of the effectiveness of CVI in influencing observers' perceptions of a university and, by association, its lecturers. A secondary question concerned the name. Photographs of two lecturers (M/F) were placed into controlled digital simulations of a university foyer featuring systematically varied CVI and name. Using a range of measures and a large-sample Internet survey of n?=?888, we found that CVI and name affected respondents' perceptions of university lecturers. However, the enhancement was exclusively upon perceptions of the male lecturer, and strongly favored traditional, heraldic CVI, with a secondary naming effect.  相似文献   

Microbial control of diamondback moth, Plutella xylostella L.(Lepidoptera: Yponomeutidae) using bacteria (Xenorhabdus nematophila) and its metabolites from the entomopathogenic nematode Steinernema carpocapsae

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.  相似文献
