[PAHs Pollution Characteristics and Source Analysis of Typical Lake and Reservoir Sediments in Jin-Ji-Liao Area].

In this research, 29 surface sediments samples of three typical lake reservoirs (in Yuqiao Reservoir, Hengshui Lake, and Dahuofang Reservoir) in the Jin-Ji-Liao area were collected and investigated, and the contents of 16 polycyclic aromatic hydrocarbons were detected using GC-MS. The results show that the Sigma PAHs (ng·g) in the sediments were 337.3-1604.

CdS nanoflake arrays for highly efficient light trapping.

CdS nanoflake arrays (NFAs) exhibit unprecedented light absorption capability, and they can serve as a scaffold to load thin organic absorbers for extraordinarily high light absorption. As a result, the hybrid solar cell consisting of NFAs and organic absorber yields a ten-times high short-circuit photocurrent compared to the counterpart device with a common planar structure.

[Catalytic degradation of dimethyl sulfoxide in aqueous solutions by liquid-phase pulsed high voltage discharge].

Fenton catalytic degradation of dimethyl sulfoxide (DMSO) by using liquid-phase pulsed high voltage discharge was carried out. The discharge was driven by a self-made pulsed power supply providing a pulse rising time of 400 ns, discharge repetition rate of 96.2 Hz, peak voltage of 20 kV.
