4. The original physical nucleation limit was calculated based on homogenous systems, implying that only the self-dimerization of individual PAH molecules was considered. Fig. 4: Inception mechanisms of polycyclic aromatic hydrocarbons in homogenous systems21. The dashed line parallels the physical ...
Plastic pollution is a planetary threat that has been exacerbated by the COVID-19 pandemic due to the surge in medical waste, personal protective equipment and takeaway packaging. A socially sustainable and economically viable method for plastic recyclin
The third step of the experiment includes potential self-resistance-associated protein overexpression which results in tolerance amelioration of the cell to the surfactin biosurfactant. In the fourth step, by the branched-chain fatty acid biosynthesis pathway engineering, they increased the precursor ...
Class-selective immuno- sorbent for trace-level determination of polycyclic aromatic hydrocarbons in complex sample matrices, used in off-line procedure or on-line coupled with liquid chromato- graphy/fluorescence and diode array detections in series. Environmental Science and Technology 33 (11), 1916...
We address the use of Euler's theorem and topological algorithms to design 18 polyhedral hydrocarbons of general formula C n H n that exist up to 28 vertexes containing four- and six-membered rings only; compounds we call "nuggets". Subsequently, we evaluated their energies to verify the ...
Table 1. IARC groups of polycyclic aromatic hydrocarbons are investigated in this study. Group 1: carcinogenic; group 2A: probably carcinogenic; group 2B: possibly carcinogenic; group 3: not classifiable; N/A: no information available. The consumption of red and processed meats is linked to ...
Versions Notes Abstract In this study, a composite material consisting of three-dimensional graphene aerogel and iron oxide nanoparticles (3DG/Fe3O4) was created and utilized for the purpose of magnetic solid-phase extraction (MSPE) of thirteen polycyclic aromatic hydrocarbon (PAH) compounds via gas...
Versions Notes Abstract The progress in ultrahigh-resolution mass spectrometry (UHRMS) and related technologies has significantly promoted the development of petroleomics. The study of petroleomics has greatly broadened our knowledge of the composition of petroleum at the molecular level, especially heavy...
The construction of 3D carbon material types frequently involves CNFs’ self-assembly into a macroscopic structure [33]. Additionally, inexpensive components like bacterial cellulose (BC) and pitch may enable large-scale production [47]. For instance, in 2014, Chen et al. worked to develop a ...
Versions Notes Abstract The genotoxicity, mutagenesis, and carcinogenic effects of polycyclic aromatic hydrocarbon (PAH) derivatives may exceed the parent PAHs. However, their influence on the soil environment has not been explored to a large extent. Oxygenated polycyclic aromatic hydrocarbons (OPAHs) ...
