Advances in spin properties of plant leaf-derived graphene quantum dots from materials to applications.

Over the past decade, graphene quantum dots have gained an inexhaustible deal of attention due to their unique zero-dimensional and quantum confinement properties, which boosted their wide research implication and reliable applications. As one of the promising zero-dimensional member and rising star of the carbon family, plant leaf-derived graphene quantum dots have attracted significant attention from scholars working in different research fields. Owing to its novel photophysical properties including high photo-stability, plant leaf-derived graphene quantum dots have been increasingly utilized in the fabrication of optoelectronic devices.

Enhancing optical characteristics of mediator-assisted wafer-scale MoSand WSon h-BN.

Two-dimensional (2D) materials and their heterostructures exhibit intriguing optoelectronic properties; thus, they are good platforms for exploring fundamental research and further facilitating real device applications. The key is to preserve the high quality and intrinsic properties of 2D materials and their heterojunction interface even in production scale during the transfer and assembly process so as to apply in semiconductor manufacturing field. In this study, we successfully adopted a wet transfer existing method to separate mediator-assisted wafer-scale from SiO/Si growing wafer for the first time with intermediate annealing to fabricate wafer-scale MoS/h-BN and WS/h-BN heterostructures on a SiO/Si wafer.

Coming back home to start up a business? A comparison between youth from rural and urban backgrounds in China.

Youth entrepreneurship is regarded as an important part of rural revitalization. Against the backdrop of the rural revitalization strategy, the Chinese government has introduced many policies to encourage return-home entrepreneurship among young people. However, highly educated youth have a lower willingness to return home for entrepreneurship, and prefer urban entrepreneurship or getting a job in a city.

Detecting latent topics and trends in blended learning using LDA topic modeling.

With the rapid application of blended learning around the world, a large amount of literature has been accumulated. The analysis of the main research topics and development trends based on a large amount of literature is of great significance. To address this issue, this paper collected abstracts from 3772 eligible papers published between 2003 and 2021 from the Web of Science core collection.

Crowdfunding Curriculum Design Based on Outcome-Based Education.

Entrepreneurship has flourished in recent years; however, since education on how to raise funds has received little attention from scholars, obtaining funds remains a difficult task. The development of crowdfunding has provided new opportunities to entrepreneurs, thus solving the funding, marketing, and distribution problems they previously faced. The main purpose of this study is to organize crowdfunding literature and to develop a crowdfunding curriculum grounded on output-based education.

Positive Emotions and Entrepreneurial Intention: The Mediating Role of Entrepreneurial Cognition.

Under the background of "mass entrepreneurship and innovation," entrepreneurship and innovation for college students not only alleviates the current social employment pressure but also sets off the upsurge of their entrepreneurship. It is a significant field to research the entrepreneurial intention of undergraduates as potential entrepreneurs, which covers the study of entrepreneurial intention from the perspective of personal traits and entrepreneurial cognition. This article studies entrepreneurial intention from two aspects: irrational positive emotions and rational entrepreneurial cognition, which aims to reveal the mechanism of positive emotions and entrepreneurial cognition on entrepreneurial intention.

Can China's industrial policies enhance the green competitiveness of the manufacturing industry?

This study innovatively uses local government regulations related to manufacturing to quantitatively identify industrial policies. The degree of influence and functional mechanism of China's industrial policies on the green competitiveness of the manufacturing industry are empirically examined using the provincial and regional panel data. Additionally, the synergistic complementary effect between industrial policy power and market forces and the fiscal decentralization's role in influencing industrial policies are investigated.

Precision Teaching and Learning Performance in a Blended Learning Environment.

Blended learning has gained increasing popularity in colleges and universities with mixed results. Precision teaching can effectively promote learning performance. The relation between perceived precision teaching (PPT) and the learning performance of college students in a blended learning environment is investigated in this paper.

High-throughput identification of antibacterials against methicillin-resistant Staphylococcus aureus (MRSA) and the transglycosylase.

To identify new transglycosylase inhibitors with potent anti-methicillin-resistant Staphylococcus aureus (MRSA) activities, a high-throughput screening against Staphylococcus aureus was conducted to look for antibacterial cores in our 2M compound library that consists of natural products, proprietary collection, and synthetic molecules. About 3600 hits were identified from the primary screening and the subsequent confirmation resulted in a total of 252 compounds in 84 clusters which showed anti-MRSA activities with MIC values as low as 0.1 μg/ml.
