With the development of nanofabrication and nanomaterials, electrokinetic nanofluidic energy conversion has been studied in nanometre-scale, even sub-1 nm channels, which can sieve organic molecules. However, achieving simultaneous nanofluidic energy conversion and organic molecular sieving...

With small and mid-sized enterprises (SMEs) and start-ups already facing a significant financing gap in normal circumstances, their financial situation has worsened considerably during the COVID-19 pandemic. We argue that crowdfunding may offer excellent financing opportunities for SMEs to stay...

China produces ≈23.4 million tons of leachate retentate (LR) annually. LR is suitable for electrochemical treatment due to its high electrical conductivity. This study compared the performances of electrochemical oxidation (EO) and electro-coagulation (EC) technology on LR treatment under...

To effectively restore the groundwater environment of the Shiping Mine (SPM) area, which is contaminated by acid mine drainage (AMD), a hydrogeochemical conceptual model was constructed based on groundwater chemistry and environmental stable isotopes. The contribution rate of various pollution...

Metal-free biochar (BC), as a green catalyst for driving advanced oxidation processes, has exhibited superior engineering applications potential in wastewater purification. However, the performance of the pristine BC for peroxymonosulfate (PMS) activation is unsatisfactory. To this end, this...

The purchasing behavior of cloud terminals is increasingly shaped by the emerging cloud services. Rather than its hardware configuration, performance of cloud intelligent terminals such as the Chromebook is more and more dependent on the cloud service capability. However, it remains unknown what...

The US advantage in per capita output, apparent from the late 19th century, is frequently attributed to its relatively large domestic market. We construct market potential measures for the US and 26 other countries between 1880 and 1913 based on a general equilibrium model of production and...

With the rapid development of the Internet, the online shopping market expands constantly. Inspired by fierce competition and complex and diverse consumer demand, personalized recommendation has become an effective marketing tool for e-commerce enterprises. However, the existing recommendation...

In this paper, I empirically examine the non-monotonic relationship between openness and within-group wage inequality predicted by  Helpman et al. (2010) using a panel data for the US, 1983–2005. Within-group wage inequality is measured for each industry and matched with exports. It can be...

This study analyzes financial risk factors of China’s Small and medium-sized enterprises (SMEs), employing Alexander Bathory model for the currently available data on the small and medium enterprise board in Shenzhen Stock Exchange. Financial risk is measured by the Alexander Bathory model....
