Nanozymes are a type of nanomaterials that exhibit enzyme-like activities, including metals (Au, Ag, Pt, Pd, etc.), metal oxides (CeO2, Fe3O4, Mn3O4, CuO, etc.), carbon-based compounds (carbon nanotubes, graphitic carbon nitride, carbon dots, etc.), and other nanomaterials (e.g.,...
WSOM is considered as a strong contributor to the light absorption of aerosol. The amount of solar radiation absorbed by WSOM relative to that of black or elemental carbon (BC or EC) were up to 40% over the whole solar spectrum and varies largely depending on the source and composition of ...
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals that contain an alkyl chain with at least one fully fluorinated carbon atom (U.S. Environmental Protection Agency, 2021). They have been manufactured and used in many industries since the 1940s (Buck et al., 2011...
In a two-dimensional diagram, there would thus be a continuum along the productivity axis from (ultra)oligotrophy to (hyper)eutrophy, while the humic lakes would stretch along the humus (or dissolved organic carbon) axis, yet at the very oligotrophic end. Similarly, in their survey of ...
SEM–EDS analysis of the hydration and carbonation reaction. Figure 4 shows the SEM images of LFS after hydration and carbonation at different temperatures and when using samples of different particle sizes. Fig. 5 shows a schematic diagram of the microstructure mechanism of hydration and ...
When present as esters, the fatty acid or fatty alcohol components preferably contain the above amount of carbon atoms. According to the invention, compounds with branched chain fatty residues as well as resin or naphthenic acids, their esters and corresponding alcohols also come under the term "...
Isothermal and Thermo-Osmotic Transport of Sorbable Gases in Microporous Carbon Membranes With the use of helium and a series of gases adsorbed to give dilute films, measurements have been made of thermo-osmotic steady-state pressure ratios esta... R Ash,RM Barrer,JH Clint,... - 《Philosophic...
it may be dissolved in an appropriate solvent and submitted to oxidation in solution, according to the process of this invention. For instance, a high melting Paraffin wax, asphalt or other bitumen might Sbe dissolved in carbon tetrachloride, or other fluid solvent having a low tendency to oxida...
a unique phase existing in the p,T-diagram of a substance in the area beyond the so-called critical point (pcrit,Tcrit), where liquid cannot be distinguished from gas and where the physical properties are intermediate between those two phases, is employed as chromatographic mobile phase. The ...
