Through in-depth analysis on history and current situations of fishery development in Poyang Lake area, this paper presents location, resource and environment advantages in development of ecological fishery. According to orientation of leading functions, Poyang Lake can be divided into breeding...

Herein, we proposed a mild method for the preparation of carbon quantum dots (CQDs) nanofluids, in which PEG-200 as raw material greatly reduced nanomaterial cost. To ensure the effectiveness of CQDs nanofluids in real seawater desalination, a systematic stability evaluation and stability...

The influence of ultrasonic impact treatment (UIT) on the microstructure, mechanical properties and burn resistance of laser solid forming (LSF) Ti60 titanium alloy samples was studied. The UIT has an obvious effect on grain refinement, residual tensile stress elimination and the improvement of...

We revisit the Armington model developed by Feenstra et al. (2018) that allows the elasticity of substitution between the domestic and foreign varieties to be different from that between alternative foreign varieties. We develop a novel two-stage gravity-based framework to estimate these two...
