This study draws on a survey of migrants in 12 cities across four major urbanizing areas in China and investigates the structure of migrant worker families' urban and rural consumption. The results show that the structure of migrant worker families' consumption has been dominated by survival...

Straw returning has been widely used as nitrogen (N) reduction measure in the North China Plain in recent years. But, little is known of the optimal plant density and N application rate of cotton under straw returning by now. In the present study, a short season cotton SCRC66 was used to study...

Micro-ductile fracture mechanism of a newly-produced meta-steel with a distinct auxetic effect is investigated mainly by performing in-situ X-ray micro-computed tomography (micro-CT) experiments. Conventional Q235 steel is chosen as a reference. The newly-produced meta-steel demonstrates a...

Owing to the abundant uranium reserves in the oceans, the collection of uranium from seawater has aroused the widespread interest. Compared to the uranium extraction from ore, uranium collection from seawater is a more environmentally friendly strategy. The amidoxime (AO) functional group has...

In recent years, the emergence of Y-series non-fullerene acceptors (NFAs) has received extensive attention in the field of organic solar cells (OSCs). Among various structural features, the side chains play a key role in fine-tuning the molecular properties of Y-series NFAs that can affect the...

Rechargeable aqueous zinc-ion batteries (ZIBs) have attracted increasing interest in large-scale energy storage systems due to their low cost, high safety, and high volumetric energy density. Manganese-based materials are one of most promising aqueous zinc-ion battery cathode materials but...
