Solar vapor generation has become a promising technology for water harvesting owing to the abundant and costless solar energy. However, there still remains great challenges to improve the usability of solar absorbers and realize high-efficient vapor generation. Herein, novel solar absorber is...

Black-odor water not only completely loses the function, but also seriously affects the environment landscape and human health. Aiming at the problems of high cost and low activity of catalysts for black-odor waters treatment by catalytic ozonation technology, this paper fabricated a stable...

In this paper, we present a novel controller design method for stochastic nonlinear systems with unmodeled dynamics, uncertain parameters, and unknown covariance noise. In order to deal with these uncertainties, a new event-based small gain controller is designed. The event triggered scheme can...

Among the large-scale energy storage devices, vanadium redox flow batteries (VRFBs) are one of the most promising candidates. Carbon felt and graphite felt have been widely adopted as electrodes, however, poor electrochemical activities and low specific surface areas have limited their rollout...

By comparing uncollateralized business loans made by a big tech lending program with conventional bank loans, we find that big tech loans tend to be smaller and have higher interest rates and that borrowers of big tech loans tend to repay far before maturity and borrow more frequently. These...

China's rapid urbanization and industrialization made it the world's largest refined copper producer and consumer. Insufficient copper ore reserves necessitated significant imports. Using material flow and scenario analysis, this study examined historical copper supply and assessed future...

This Element synthesizes the current state of research on organizational social networks from its early foundations to contemporary debates. It highlights the characteristics that make the social network perspective distinctive in the organizational research landscape, including its emphasis on...
