For air conditioning equipment, mini-channel heat evaporator/heat exchanger excels in performance over the traditional fin-tube counterpart. However, the uniformity of two-phase refrigerant flow distribution in mini-channel evaporator remains unsolved. To enhance the flow distribution in...

In digital economy, firm’s digital transformation is an important means of achieving high-quality development. Adopting career concerns theory, we examine rookie CEOs’ impact on firms’ digital transformations, using Chinese A-share listed firms from 2007 to 2019. (1) Rookie CEOs disclose...

Using a large sample of data on insiders’ stock selling and rumors about A-share listed companies in China, this study empirically tests whether and how rumors about companies are used to manipulate the market in the context of insiders’ stock selling. We find that the probability of a...

This paper shows that a standard deviation increase in carbon emissions by listed firms in China increases the odds of M&A (a green asset acquisition) by over 33% (over 81%) to achieve a green transition. However, firms decrease their R&D investment which tends to be fraught with technical and...

Organic solvent nanofiltration (OSN), as an emerging membrane separation technology, holds great potential in pharmaceutical and chemical applications. However, the development of such a promising technology is severely retarded by the trade-off between permeability and selectivity. Herein, we...

This paper provides a market-microstructure analysis of exchange rate dynamics in the Chinese foreign exchange market using a vector autoregressive (VAR) modeling framework. An index of order flow is constructed in the Chinese context to reflect excess demand pressure in the foreign exchange...

Photocatalytic degradation is a promising means to restore the ever-growing pharmacological active compounds (PHACs) contamination in the water environment. Herein, the oxygen vacancies (OVs) modulated Z-scheme CuWO4/CuBi2O4 hybrid systems were fabricated at thermal treatment by in-situ loading...
