An empirical study on the measurement and influencing factors of carbon emission efficiency in China's transportation industry


Gang Zeng et al. View all

Ecology, environmental change and management

The severe climate problem has forced the Chinese government to put forward the goal of "carbon peak" and "carbon neutrality", and the transportation industry is a key area of carbon emission reduction. Based on this background, this paper introduces the BCC model and the Malmquist-Luenberger index...

Entrapment of green seaweed Caulerpa Scalpelliformis for extracting Pb(II), Ni(II) and Zn(II) metal ions from aqueous solutions


Kousalyadevi G et al. View all

Water and Wastewater Treatment

From this study, green seaweed Caulerpa Scalpelliformis is utilized as a sorbent for the removal of three metals such as lead (Pb), nickel (Ni) and zinc (Zn). Adsorption tests showed that maximum removal efficiency of 75.02% for Pb, 80% for Ni and 91.11% for Zn was obtained at an optimal equilibrium...

Preparation and Characterization of Polyvinyl Alcohol/Polyhedral Oligosilsesquioxane Hybrid Membrane for Pervaporation Separation of High-Concentration ε-Caprolactam Solution


Lin WH. et al. View all


We used Vinyl-polyhedral oligosilsesquioxane (POSS)as a modified material and polyvinyl alcohol (PVA) to make a hybrid membrane for the pervaporation membrane separation of high-concentration caprolactam solution. The membranes were characterized by Fourier transform infrared spectroscopy, X-ray...

Spatiotemporal evolution and driving factors of carbon emissions in Qingdao City based on GeoDetector


Peifeng Zhang et al. View all

Urban environment and health

Investigating the spatiotemporal characteristics and factors of urban carbon emissions is essential to reduce carbon emissions and achieve dual carbon goals. In this study, we examined the change tendency of carbon emissions using the coefficient of variation, the Sen’s slope method, and the Mann...

Microbial Technique to Treat Recycled Aggregates from Construction Waste for its Effective reutilization in Concrete


Jagan S et al. View all

Solid Waste Management

Excessive consumption of natural resources for concrete production results in the diminution of conventional resources, leading to the scarcity of construction materials. Perhaps, the dumping of construction wastes increases the municipal wastes ensuing in disposal problems. The dumped construction...
