Sponges are the oldest known extant animal-microbe symbiosis. These ubiquitous benthic animals play an important role in marine ecosystems in the cycling of dissolved organic matter (DOM), the largest source of organic matter on Earth. The conventional v
Extracellular vesicle (EV) secretion is a highly conserved evolutionary trait in all organisms in the three domains of life. The packaging and release of EVs appears to be a bulk-flow process which takes place mainly under extreme conditions. EVs participate in horizontal gene transfer, which supp...
However, the adsorption or catalytic oxidation of VOCs on the particulate surface are the two heterogeneous reaction pathways to the formation of SOA. Figure 7. TEM images of the mixing states and EDS spectra of individual particles. (a) Mixture of S-rich, fly ash, soot, and coated by ...
(ii) The ozone reacts with pollute via cycloaddition reaction by forming a five-member ring ozonide structure [5]. (iii) Ozone being an electrophilic agent can attack the nucleophilic position of the organic substances and the group in the aromatic molecule, such as -OH−, -NO2−and –...
Considering the prevalence of diatoms, these polysaccharides are produced in large quantities and play a non-negligible role in global carbon cycling. Many microalgae also exudate polysaccharide-rich extracellular polymeric substances (EPS). EPS have many functions, e.g., providing a nutritious matrix ...
Nanoemulsion, also referred to as ultrafine emulsion, submicron emulsion, and miniemulsion, is a class of thermodynamically stable and transparent dispersions of oil and water.107Nanoemulsions are heterogeneous systems composed of two immiscible liquids, in which one (dispersed phase) is dispersed in for...
Children are vulnerable to the neurotoxic effects of chemicals, especially during the prenatal period, when there is an immature blood-brain barrier and neuronal growth, migration, and myelination processes that occur on a specific and rapid schedule [17, 18]. Moreover, some toxic substances can ...
The interaction of CDOM and sunlight is a principal process controlling DOM transformation and mineralization. By examining the DOM absorbance and fluorescence properties, it is possible to obtain or infer important quantitative (e.g., concentrations of CDOM or humic substances) and qualitative ...
DISTLM relies on multiple regression models that can accommodate a mixture of categorical and continuous predictors using dbRDA. This is a constrained ordination of sample sites using the same resemblance matrix on the Jaccard similarity coefficient [36]. The relationship between each environmental ...
