To investigate the metal oxide thin film application in optoelectronic field via changing its conduction type, the p–n junction with Bi-doped p-type ZnO and n-type MoS2 is fabricated by pulsed laser deposition. In this work, we explore the photovoltaic effect of the ZnO/MoS2 heterostructure, focusing on the function of tuning Bi contents in enhancing the photoelectric conversion efficiency. Doping-Bi ZnO thin film perfectly shows stable p-type semiconductor properties with high carrier concentration (about from 1 × 1016 to 1 × 1017 cm−3), high rational mobility (363 cm−2 V−1 s−1) and low resistivity (216.7 Ω). In addition, MoS2 clearly exhibits large quantities of nanosheets and distinct vertically standing structure. The power conversion efficiency (PCE) of ZnO:Bix/MoS2 enhances from 0.518% to 2.430% along with increasing doping Bi element from 1% to 7%, but when doping Bi content reaches 10%, the PCE decrease 0.552%. Essentially, the ability of capturing photon-generated carriers in ZnO:Bix film gradually increases as doping Bi content to without excessive doping content. These findings illustrate that this proposed Bi-doped ZnO has potential in promoting the photoelectric conversion efficiency of MoS2 based p–n junction. [ABSTRACT FROM AUTHOR]

The polysiloxane modified with cationic and perfluorocarbon groups could form film on the polyester surface by macromolecular self-assembly process. The thin film on the polyester surface could affect the color shade of dyed materials. The effect of the polysiloxane film on the color shade of the dyed polyester was investigated by reflectance spectra, color yield ( K/ S) and the color differences (Δ E). The colorimetric data of CIELAB was discussed. The results show that the thin film of the polysiloxane modified with cationic and perfluorocarbon groups on the polyester surface had good water repellency. The effect of the polysiloxane film on the color shade of dyed polyester was noticeable. The K/ S of the dyed polyester fabrics with the modified polysiloxane film obviously increased. The reflectance spectra of the dyed fabrics treated without and with the modified polysiloxane had not significant change. [ABSTRACT FROM AUTHOR]

There are five hot springs named separately SHANGT, ZHONGT, WENT, XIAT and SHENT in Lushan County, Pingdingshan City, Henan Province. The archaeal diversity of the five hot springs was investigated and analyzed. 16S rDNA v4-5 genes of arehaea were sequenced by lllumina Hisiq2500 PE250 technolog). The numbers of sample sequences and OTUs were sorted by using Uparse, Mothur, SILVA, MUSCLE and Qiime software. Finally, the archaeal abundance and diversity in the five hot springs were analyzed. 87 993, 67 326, 44 400, 48 611 and 48 495 effective reads have been obtained from SHANCT, ZHONCT, WENT, XIAT and SHENT respectively, and 520, 280, 678,451 and 437 OTUs have been acquired. The analysis of archaeal classification showed that the arehaea from the five hot springs could be classified into 11 phyla, in which Thaumarchaeota accounted for 95. 25% and was the dominant arehaea. In the genera level, the dominant arehaea of the SHANGT, ZHONGT and WENT was Candidalus-Nilrosocaldus, and unidentified-Thaumarchaeota was the dominant arehaea in XIAT and SHENT. The results showed that the five hot springs in Lushan are rich in microbial resources. The research provided basic data for further research and utilization of the arehaea resources in the five hot springs of Lushan. [ABSTRACT FROM AUTHOR]
