Abstract

Purpose

The purpose of this paper was to investigate how variations in the geometry of silicon chips and the presence of surface defects affect their static bending properties. By comparing the bending radius and strength across differently sized and treated chips, the study sought to understand the underlying mechanics that contribute to the flexibility of silicon-based electronic devices. This understanding is crucial for the development of advanced, robust and adaptable electronic systems that can withstand the rigors of manufacturing and everyday use.

Design/methodology/approach

This study explores the impact of silicon chip geometry and surface defects on flexibility through a multifaceted experimental approach. The methodology included preparing silicon chips of three distinct dimensions and subjecting them to thinning processes to achieve a uniform thickness verified via scanning electron microscopy (SEM). Finite element method (FEM) simulations and a series of four-point bending tests were used to analyze the bending flexibility theoretically and experimentally. The approach was comprehensive, examining both the intrinsic geometric factors and the extrinsic influence of surface defects induced by manufacturing processes.

Findings

The findings revealed a significant deviation between the theoretical predictions from FEM simulations and the experimental outcomes from the four-point bending tests. Rectangular-shaped chips demonstrated superior flexibility, with smaller dimensions leading to an increased bending strength. Surface defects, identified as critical factors affecting flexibility, were analyzed through SEM and atomic force microscopy, showing that etching processes could reduce defect density and enhance flexibility. Notably, the study concluded that surface defects have a more pronounced impact on silicon chip flexibility than geometric factors, challenging initial assumptions and highlighting the need for defect minimization in chip manufacturing.

Originality/value

This research contributes valuable insights into the design and fabrication of flexible electronic devices, emphasizing the significant role of surface defects over geometric considerations in determining silicon chip flexibility. The originality of the work lies in its holistic approach to dissecting the factors influencing silicon chip flexibility, combining theoretical simulations with practical bending tests and surface defect analysis. The findings underscore the importance of optimizing manufacturing processes to reduce surface defects, thereby paving the way for the creation of more durable and flexible electronic devices for future technologies.

Abstract

With high-speed urbanization and strict requirements on energy conservation and environmental protection, eco-city has become the priority of urban development in China. Governments of all levels promote various eco-city planning schemes within a short term, but most schemes are characterized by randomness and subjectivity. To solve the lack of scientific pre-implementation evaluation for eco-city planning and improve eco-city construction quality, a systematic analysis is conducted in this study from three dimensions, namely, eco-city planning scheme, operating mechanism, and guarantee measures. A 3D evaluation model for eco-city planning is constructed through index selection. Schemes are ranked comprehensively with the distance measure method, and projection analysis is performed with the four-grid evaluation screen. Finally, the 3D evaluation model is applied to evaluate eco-city planning for Shenzhen, Chongqing, and Weifang. Results show that the model can be used to evaluate eco-city planning schemes effectively and comprehensively and offers targeted optimization suggestions in accordance with the evaluation results. Construction of the 3D evaluation model of eco-city planning based on the distance measure to determine the reasonability of eco-city planning reduces the institutional and social costs of eco-city planning practices.

Abstract

Purpose

The purpose of this paper is to investigate the impact of different sources of external financing and internal financial capabilities on competitiveness and sustainability. This paper also studies the nature of their relationships related to regulations on external financing in Chinese capital market.

Design/methodology/approach

Resource- and industry-based views provide a theoretical background. Based on balanced panel of 4,530 firm-year observations, hierarchical regressions were used to examine the research model.

Findings

Results support the idea that the strict Chinese regulatory regime allows some firms to access capital and debt markets for financing more than others. It was found that firms’ internal financing abilities do not offer a significant advantage compared to external financing abilities; firms’ abilities to raise capital from existing shareholders, the public and easy access to bank financing are related positively for an advantage on firm’s competitiveness within a industry. Firms with the ability to offer shares to existing shareholders, issue non-convertible and convertible bonds and access to bank financing are sustainable in long-run.

Research limitations/implications

This study focuses on sources of financial capability of Chinese listed firm impact on competitiveness and sustainability. It is context specific to a regulated market. Hence, it is necessary to replicate this study in other contexts.

Practical implications

Implications include the need to mobilize external financial resources for small and privately-owned firms and to further reform security regulations to ensure fair competition and sustainability.

Originality/value

The authors originally investigate the effect of sources of financial capability impact on firms’ competitiveness and sustainability in a regulated market. The paper explains the relationships, and enhances the understanding of regulated capital market and existing literature.

Abstract

City wall is an important symbol of ancient Chinese cities with unique geographical and cultural characteristics. Thus, the preservation of this historic landmark is considered significantly important. However, numerous residential construction activities and changes in ecological environment have destructed a great portion of the city walls in recent years. This study looks into the preservation of the ancient city walls from the systematic perspective and in line with the actual characteristics of Longdong Region to provide guideline measures for the protection and restoration of such landmark. Cognition and preservation are adopted extensively to investigate the specific situation of and the factors that influence the ancient city walls in this region. Preservation strategies for the city walls, including the “Axis-Point” system, planning control, and authenticity readability, are presented. The ancient city walls in Longdong Region can be preserved by protecting the entire region, the city, and the main wall body. The systematic method and preservation strategies at the “macro perspective,” “medium perspective” and “micro perspective” levels can solve the preservation problems of the ancient city walls in Longdong Region effectively.

Abstract

Purpose

The purpose of this study is to provide insights into bootleg innovation by investigating whether perceived hindrance stressors play an important role in bootlegging and how different organizational ownership types (state-owned enterprises (SOEs) vs non-SOEs) affect this relationship.

Design/methodology/approach

The study samples comprised 3,967 employees from 674 knowledge-intensive companies in southern China. Multilevel structural equation modeling was used to test the hypotheses.

Findings

Drawing on the conservation of resources (COR) theory, the results show that hindrance stressors have a curvilinear (U-shaped) influence on bootleg innovation, and that the curve relationship between the hindrance stressors and bootlegging is more pronounced among employees in non-SOEs.

Practical implications

The findings indicate that either a low or high level of hindrance stressors can activate a high level of bootlegging activities among employees. These results suggest that managers need to be vigilant in detecting the level of hindrance because different motivations predominate at different stressor levels.

Originality/value

Based on the COR theory, the findings cast perceived hindrance stressors as an antecedent of bootlegging at the individual level. The inquiry into state ownership types further provides a comprehensive understanding of the non-linear relationship between hindrance stressors and bootlegging.

Abstract

Purpose

The spread of rumors on social media has caused increasing concerns about an under-informed or even misinformed public when it comes to scientific issues. However, researchers have rarely investigated their diffusion in non-western contexts. This study aims to systematically examine the content and network structure of rumor-related discussions around genetically modified organisms (GMOs) on Chinese social media.

Design/methodology/approach

This study identified 21,837 rumor-related posts of GMOs on Weibo, one of China's most popular social media platforms. An approach combining social network analysis and content analysis was employed to classify user attitudes toward rumors, measure the level of homophily of their attitudes and examine the nature of their interactions.

Findings

Though a certain level of homophily existed in the interaction networks, referring to the observed echo chamber effect, Weibo also served as a public forum for GMO discussions in which cross-cutting ties between communities existed. A considerable amount of interactions emerged between the pro- and anti-GMO camps, and most of them involved providing or requesting information, which could mitigate the likelihood of opinion polarization. Moreover, this study revealed the declining role of traditional opinion leaders and pointed toward the need for alternative strategies for efficient fact-checking.

Originality/value

In general, the findings of this study suggested that microblogging platforms such as Weibo can function as public forums for discussing GMOs that expose users to ideologically cross-cutting viewpoints. This study stands to provide important insights into the viral processes of scientific rumors on social media.

Abstract

Purpose

Human computation games (HCGs) that blend gaming with utilitarian purposes are a potentially effective channel for content creation. The purpose of this paper is to investigate the driving factors behind players’ adoption of HCGs through a music video tagging game. The effects of perceived aesthetic experience (PAE) and perceived output quality (POQ) on HCG acceptance are empirically examined.

Design/methodology/approach

An integrative structural model is developed to explain how hedonic and utilitarian factors, including PAE and POQ, working with another salient factor – perceived usefulness (PU) – affect the acceptance of HCGs. The structural equation modeling method is used to verify the proposed model with data from 124 participants.

Findings

Results show that PAE is the strongest predictor of HCGs adoption. PU has a significant impact on individuals’ attitude toward HCGs. POQ is a salient predictor of PU and PAE, and its indirect effect on attitude is significance.

Originality/value

From an academic point of view, this study provides a good understanding of the driving factors behind player acceptance of HCGs and adds new knowledge to games with utilitarian purposes. It is also one of the first to describe the components of game enjoyment with a taxonomy of aesthetic experiences. From the practical perspective, the investigation of the specific factors behind adoption of HCGs provides specific guidelines for their design and evaluation.

Abstract

Purpose

This study aims to improve the corrosion resistance of TA2-welded joints by superhydrophobic surface modification using micro-arc oxidation technology and low surface energy substance modification.

Design/methodology/approach

The microstructure and chemical state of the superhydrophobic film layer were analyzed using scanning electron microscopy, energy dispersive X-ray spectroscopy, three-dimensional morphology, X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform infrared absorption spectroscopy. The influence of the superhydrophobic film layer on the corrosion resistance of TA2-welded joints was investigated using classical electrochemical testing methods.

Findings

The characterization results showed that the super hydrophobic TiO2 ceramic membrane was successfully constructed on the surface of the TA2-welded joint, and the construction of the super hydrophobic film greatly improved the corrosion resistance of the TA2-welded joint.

Originality/value

The superhydrophobic TiO2 ceramic membrane has excellent corrosion resistance. The micro nanostructure in the superhydrophobic film can intercept air to form an air layer to prevent the corrosion medium from contacting the surface, thus, improving the corrosion resistance of the sample.
