technology Hotspot Networks in Industry–Academia–research Institute Collaboration and Development Trends

Journal of the Knowledge Economy 2025年 1-23页

作者： Chang, Shu-Hao Science and Technology Policy Research and Information Center National Applied Research Laboratories Taipei Taiwan

Following the increasing attention to and development of industry–academia–research (IAR) institute collaboration, studies on IAR institute collaboration have increased considerably. However, although most of these studies have examined the mechanisms for collaboration and innovation performance, they have failed to identify the technology hotspots for IAR institute collaboration. On the basis of IAR institute collaboration patent analysis, this study analyzes key players of the collaboration to identify the technology hotspots in the technology network. Because few studies have paid attention to the status of each country in the IAR institute collaboration patent technology network, this study integrates countries in the analysis model to identify the niches for each country in the IAR institute technology collaboration. The results reveal that technology hotspots in the technology network of IAR institute collaboration are focused on interdisciplinary fields, such as those involving the preparation, development, and evaluation of medicine and those involving energy generation and the reduction of greenhouse gas emissions. This trend in technological development reflects the tendency of national governments to promote innovation in technological fields. Notably, France and the USA have played key roles in the technology network of international IAR institute collaboration. The findings of the present study provide a reference for governments seeking to establish alliances for IAR institute collaboration and to promote the development of new technology.

引用

ACS applied Materials and Interfaces 2024年第15期16卷 18754-18767页

作者： Sakthivel, Mani Ho, Kuo-Chuan Department of Chemical Engineering National Taiwan University Taipei10617 Taiwan Advanced Research Center for Green Materials Science and Technology National Taiwan University Taipei10617 Taiwan Institute of Polymer Science and Engineering National Taiwan University Taipei10617 Taiwan

In this work, we demonstrated the synthesis of anions (X = selenium (Se), sulfur (S), and phosphorus (P)) doped cobalt oxytelluride (X-CoOTe) with oxygen and tellurium dual vacancies using hydrothermal methods, followed by selenization, sulfurization, and phosphorization reactions. Especially, the Se-CoOTe-modified nickel foam (Se-CoOTe/NF) electrode delivered a higher specific capacity (752.95 C/g) and an extremely lower charge transfer resistance (0.87 Ω) than S-CoOTe/NF and P-CoOTe/NF due to the higher metallic conductivity of Se. Both oxygen and tellurium vacancies facilitate higher charge transfer conductivity, specific capacity, and stability. On the other hand, banana stem core fiber-derived activated carbon fiber (AC) with exfoliated carbon sheet, cracked surface, and corresponding high surface area boosts the excellent cycle stability up to 4000 cycles with capacitance retention of 100.29%. Thus, the asymmetric device (Se-CoOTe/NF//AC/NF) exhibited an extendable cell voltage (1.55 V), higher energy density (155.6 W h kg-1) at a power density (1356.2 W kg-1), and generous long-term stability (100% retention up to 10 000 cycles) in a liquid alkaline electrolyte. In the practicability test, the proposed asymmetric device mutually showed an increased operating voltage from 1.55 to 4.65 V for a three-series connection. In a three-series connection, a single white LED and an LED string glowed efficiently. This new finding will be very useful to develop tellurium-based chalcogenides and biowaste-derived carbon for energy storage applications. © 2024 The Authors. Published by American Chemical Society.

This review examined the impact of online learning environments (OLE) on acquiring transferable skills (TS) through an analysis of 31 papers from the Web of science database. Significant attention is given to critical thinking and communication skills, with moderate consideration given to creativity, problem-solving, and cooperation skills. Lesser emphasis is placed on negotiation, decision-making, self-management, resilience, and participation, while respect for diversity and empathy skills remains unexplored. STEM dominated the research focus in many articles, primarily focusing on higher education institutions, with limited attention to primary and secondary schools. Learning management systems (LMS) and online platforms are widely used for teaching TS. Quantitative research methods predominated, emphasizing the cognitive dimension of TS, and limited exploration of the social dimension. Therefore, OLE significantly impacts TS development, contributing to a more knowledgeable society, improved education, lifelong learning, personal empowerment, enhanced employee skills, and entrepreneurial outcomes fostering economic development. OLE also plays a pivotal role in nurturing civic engagement, peace, and social harmony. However, some articles underscore negative consequences, including challenges in communication skill development, prolonged adjustment periods, and increased challenge for learners. According to the review's findings, the authors provide recommendations to teachers, educators, curriculum designers, and researcher. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

The effects of potassium concentration on the metabolomic and electrical responses of strawberry fruits were investigated. The potassium concentration of fruit harvested in January, March, and April were determined. Quality differences were observed in April, with lower potassium levels resulting in lower Brix values and acidity. Intracellular resistance and cell membrane capacity, as determined by impedance analysis, were correlated with acidity and sugar content, respectively. In addition, metabolomic analysis by gas chromatography-tandem mass spectrometry (GC-MS / MS) indicated that stress markers, such as putrescine, were detected before quality differences appeared. While impedance analysis is useful for evaluating the tissue condition of strawberries, metabolomic analysis can be used to predict quality changes. © 2023 Elsevier B.V.. All rights reserved.

Temperature dependence of the deformation behavior and mechanical response of CoCrNi medium-entropy alloy: Experiment and simulation

引用

Journal of Materials research and technology 2023年 24卷 9731-9742页

作者： Deng, H.W. Ge, H.E. Zhan, C.Y. Liu, Y. Ren, Q.S. Liu, Z.Y. Zhang, T. School of Physics and Materials Science Research Center for Advanced Information Materials Guang Zhou University Guangdong Guangzhou510006 China China Nuclear Power Technology Research Institute Guangdong Shenzhen518031 China

Tailoring the microstructure of metallic materials by controlling the fabrication process is crucial to achieving superior mechanical properties. Herein, the mechanism of modifying the microstructure and mechanical properties of medium-entropy CoCrNi alloys was investigated by equal-channel angular pressing (ECAP) at room temperature (RT) and cryogenic temperature (CT) and post-deformation annealing (PDA) and was analyzed by molecular dynamics simulations. It was found that temperature influences the deformation mechanism of the alloy, dislocations, stacking faults, deformation twins, and FCC-HCP phase transitions, which assume different roles at different temperatures. The dislocation density of the ECAP-CT sample is significantly higher than that of the ECAP-RT sample;however, the ECAP-RT sample exhibits unique deformation features of kink bands and hierarchical twin structure, resulting in dynamic grain refinement effects. In addition, the HCP phase strength increment caused by annealing-induced HCP phase transformation is higher in the ECAP-RT sample than in the ECAP-CT sample, thus leading to a substantial increase in strength after PDA. The present study exhibits the strengthening mechanisms and provides a generic approach to obtaining desirable mechanical properties of alloys. © 2023 The Author(s)
