Performance of Fe-N/C Oxygen Reduction Electrocatalysts toward NO2-, NO, and NH2OH Electroreduction: From Fundamental Insights into the Active Center to a New Method for Environmental Nitrite Destruction.

open access: yesJournal of the American Chemical Society, 2016
Although major progress has recently been achieved through ex situ methods, there is still a lack of understanding of the behavior of the active center in non-precious metal Fe-N/C catalysts under operating conditions.

Single Magnetic Atom on a Surface: Anisotropy Energy and Spin Density [PDF]

open access: yesarXiv, 2012
Studying single-atom magnetic anisotropy on surfaces enables the exploration of the smallest magnetic storage bit that can be built. In this work, magnetic anisotropy of a single rare-earth atom on a surface is studied computationally for the first time.

Multiple metabolisms constrain the anaerobic nitrite budget in the Eastern Tropical South Pacific

open access: yes, 2017
The Eastern Tropical South Pacific is one of the three major oxygen deficient zones (ODZs) in the global ocean and is responsible for approximately one third of marine water column nitrogen loss.

Expression of the nirS, hzsA, and hdh Genes in Response to Nitrite Shock and Recovery in Candidatus Kuenenia stuttgartiensis.

open access: yesEnvironmental Science and Technology, 2016
In this study, Candidatus Kuenenia stuttgartiensis were subjected to distinct nitrite shocks (66 (control), 200, 300, 400, and 500 mg N/L), and the responses of mRNA levels of cytochrome cd1 nitrite/nitric oxide oxidoreductase (nirS), hydrazine synthase (

In situ growth of α-Fe2O3 nanorod arrays on 3D carbon foam as an efficient binder-free electrode for highly sensitive and specific determination of nitrite

open access: yes, 2017
Long-term accumulation and overdose of nitrite ions have been proven to pose a great threat to the ecological environment and public health. Therefore, it is highly desirable to construct a novel architecture electrode for the accurate quantification of ...

Micro-sized cold atmospheric plasma source for brain and breast cancer treatment [PDF]

open access: yesarXiv, 2018
Micro-sized cold atmospheric plasma (uCAP) has been developed to expand the applications of CAP in cancer therapy. In this paper, uCAP devices with different nozzle lengths were applied to investigate effects on both brain (glioblastoma U87) and breast (MDA-MB-231) cancer cells.
