Unraveling the synergistic promotion mechanism of Fe coupling phragmites australis biomass for nitrogen removal in coastal wetland: From low to moderate salinities.

The simulated coastal constructed wetlands supplemented with Fe and phragmites australis (P.A) biomass (CW-M) were constructed to improve nitrogen removal under different salinities (0-15‰). Results showed that the denitrification performance of CW-M were improved significantly, with the higher NO-N removal of 72-94% and lower NO emission flux, when compared with mono-P.

Working Voltage Switching the Photo-/Thermo-Electric Effect for Distinct Ultraviolet and Infrared Signal Detection.

The combination of sensing invisible ultraviolet photons and infrared radiation can significantly enhance target recognition by offsetting their own limit in a short sensing range and poor spatial resolution. However, the difference in their wavelength sets unique requirements for sensing materials and devices, which makes it hard to establish their implementation in a single detector. In this work, we present the design of a single detector with CHNHPbCl (MAPbCl) for distinguishing ultraviolet and IR signals by switching its operating mode in the photo-/thermo-electric effect.

Three New Species of from East and Northeast China.

species are ubiquitous in the environment and are of substantial importance, especially in industrial and medical aspects. During our investigation of the biodiversity of , three new species were discovered in soil samples collected from East and Northeast China. They were determined as new to science based on morphological comparisons and phylogenetic analyses, and were found to belong to the subgenus section and subgenus sections and .

Salinity effect on denitrification efficiency with reed biomass addition in salt marsh wetlands.

Five simulated salt marsh wetlands with reed were constructed to investigate the effect of salinity on denitrification efficiency and its enhancement by reed biomass addition. It was found that the salinity of 7 ‰ and 10 ‰ could promote the organic carbon release of reed biomass. Results showed that the nitrate removal was highest at the salinity of 7 ‰, and would be further enhanced from 54.

Enhanced nitrogen removal via iron‑carbon micro-electrolysis in surface flow constructed wetlands: Selecting activated carbon or biochar?

The iron-assisted autotrophic denitrification was plagued by passivation when introduced in surface flow constructed wetlands (SFCWs). Iron‑carbon micro-electrolysis (Fe/C-M/E) could facilitate the transfer of electrons during the utilization of iron. In this study, iron scraps coupling with activated carbon and biochar were applied to explore the effects of carbon materials on autotrophic denitrification.

Expression and clinical significance of Notch signaling genes in colorectal cancer.

The objective of this study was to explore the expression and clinical significance of Notch signaling genes in colorectal cancer. Colorectal cancer samples were prospectively collected from patients post-surgery at the 3rd Affiliated Hospital, Nanjing University of Traditional Chinese Medicine. Immunohistochemistry of tissue arrays was used to analyze the samples and genes involved in the Notch signaling pathway.
