Examining the asymmetric socioeconomic determinants of CO2 emissions in China: challenges and policy implications.

A better socioeconomic development is necessary for environmental sustainability. The current study scrutinizes the asymmetric socioeconomic factors of CO2 emissions in China by using the nonlinear ARDL approach. This study is based on annual data covering the period from 1980 to 2019.

Synergic effect of adsorption and biodegradation enhance cyanide removal by immobilized Alcaligenes sp. strain DN25.

A high efficiency and stability polyurethane-foam (PUF)-immobilized cell system was constructed to remove cyanide based on simultaneous adsorption and biodegradation (SAB). The performance of the PUF-immobilized system was evaluated by comparison with the freely suspended cell system. The SAB system exhibited more effective and robust, and could still remain degradation activity even at 40 °C or pH 11.
