Interactions of Oxygen and Water Molecules with Pyrite Surface: A New Insight
Pyrite is the most
common sulfide in nature, and it is well-known
for its roles in acid mine drainage, flotation separation of useful
metal (Cu, Pb, Zn, and Mo) sulfide minerals, optoelectronic and photovoltaic
application, pneumoconiosis, and even in the origin of life. However,
the detailed oxidation behaviors of pyrite are still unclear and not
well-understood. New oxidation pathways by O<sub>2</sub> on the pyrite
(100) surface have been found in this work for the first time using
density functional theory simulation; that is, besides Fe sites, S
sites are also possible oxidation sites in the initial oxidation state
of pyrite, where easier and stronger oxidation may occur. This is
the first time to confirm the other researchers’ conjecture
on the direct oxidation of S sites, which explains the isotopic composition
experiments that a minor amount of O<sub>2</sub> is permanently incorporated
into SO<sub>4</sub><sup>2–</sup> during pyrite oxidation (O
in SO<sub>4</sub><sup>2–</sup> is mainly derived from water).
We constructed various H<sub>2</sub>O–O<sub>2</sub> coadsorption
models on the pyrite surface by considering the adsorption sequence
of H<sub>2</sub>O and O<sub>2</sub>. It is found that the H<sub>2</sub>O molecule undergoes step-wise dissociation in the presence of the
O<sub>2</sub> molecule. Hydroxyl radical •OH is the reactive
oxygen species during H<sub>2</sub>O dissociation. Cyclic voltammetric
measurements confirm the presence of •OH. In addition, H<sub>2</sub>O<sub>2</sub> may also be formed on the surface in terms of
H<sub>2</sub>O-then-O<sub>2</sub> sequence adsorption

Data_Sheet_1_Acupuncture and moxibustion therapy for cognitive impairment: the microbiome–gut–brain axis and its role.docx
Cognitive impairment poses a significant burden on individuals, families, and society worldwide. Despite the lack of effective treatment strategies, emerging evidence suggests that the microbiome–gut–brain (MGB) axis may play a critical role in the pathogenesis of cognitive impairment. While targeted treatment is not yet comprehensive, recently, acupuncture and moxibustion therapy has participated increasingly in the treatment of degenerative diseases and has achieved a certain therapeutic effect. In this review, the possible mechanisms by which acupuncture and moxibustion therapy may improve cognitive impairment through the MGB axis are reviewed, including regulating gut microbial homeostasis, improving intestinal inflammation mediated by the neuroendocrine–immune system, and enhancing intestinal barrier function. We also discuss common acupoints and corresponding mechanism analysis to provide insights into further exploration of mechanisms that target the MGB axis and thereby intervene in cognitive impairment.</p
Image_1_Bacteria from nodules of Abrus mollis Hance: genetic diversity and screening of highly efficient growth-promoting strains.pdf
IntroductionAbrus mollis Hance. (AM) is an important species used in southern Chinese medicine. It is mainly found in Guangdong and Guangxi provinces in China, and it is effective in the treatment of hepatitis. Endophytic bacteria are known to affect the growth and quality of medicinal plants. However, there are limited reports describing endophytic bacteria related to AM.MethodsIn the present study, Illumina-based 16S rRNA gene sequencing was used to investigate the endophytic bacterial communities of root nodules of AM at five sampling sites in Guangxi. In addition, 179 strains of endophytic bacteria were isolated and categorized into 13 haplotypes based on recA sequence analysis.ResultsThe phylogeny of the 16S rRNA gene sequences revealed a predominance of nonrhizobial endophytes. Microbial diversity analysis showed that Proteobacteria was the dominant phylum in all samples, while Bradyrhizobium was the dominant genus in different samples. An efficient strain, Rhizobium tropici FM-19, was screened and obtained through greenhouse experiments. The AM plants inoculated with this strain showed the best growth performance and high nitrogen fixation and nodulation capacity. Notably, total phenols and total flavonoids, important active components in AM, increased by 30.9 and 42.7%, respectively, after inoculation with Rhizobium tropici FM-19.DiscussionThis study provides insights into the complex microbial diversity of AM nodules and provides strain information for the efficient cultivation of AM.</p

Direct Formation of Electronic Excited NO<sub>2</sub> Contributes to the High Yield of HONO during Photosensitized Renoxification
Photosensitized renoxification of HNO3 is
found to produce
HONO in an unexpectedly high yield, which has been considered an important
source for atmospheric HONO. Conventionally, the production of HONO
is ascribed to the secondary photolysis of the primarily formed NO2. In this study, by using humic acid (HA) as a model environmental
photosensitizer, we provide evidence of the direct formation of NO2 in its electronic excited state (NO2*) as a key
intermediate during the photosensitizing renoxification of HNO3. Moreover, the high HONO yield originates from the heterogeneous
reaction of the primarily formed NO2* with the co-adsorbed
water molecules on HA. Such a mechanism is supported by the increase
of the product selectivity of HONO with relative humidity. Further
luminescence measurements demonstrate clearly the occurrence of an
electronic excited state (NO2*) from photolysis of adsorbed
HNO3 on HA. This work deepens our understanding of the
formation of atmospheric HONO and gives insight into the transformation
of RNS
