The kinetics of Criegee intermediates are important for atmospheric ***,the quantitative kinetics of Criegee intermediates are still very.limited,especially.for those with hy.roxy.***,we calculate rate constants for the unimolecular reaction of E-gly.olaldehy.e oxide[E-hy.roxy.thanal oxide,E-(CH_(2)OH)CHOO],for its reactions with H_(2)O and(H_(2)O)_(2),and for the reaction of the E-(CH_(2)OH)CHOO…H_(2)O complex with H_(2)*** the highest level of electronic structure,we use W3X-L//CCSD(T)-F12a/cc-pVDZ-F12 for the unimolecular reaction and the reaction with water and W3X-L//DF-CCSD(T)-F12b/jun-cc-pVDZ for the reaction with 2 water *** the dy.amics,we use a dual-level strategy.that combines conventional transition state theory.with the highest level of electronic structure and multistructural canonical variational transition state theory.with small-curvature tunneling with a validated density.functional for the electronic structure.

The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presence of a trihy.rid nanofluid(Fe_3O_4-Au-Zn-blood) is carried out. Three ty.es of nanoparticles, each having a different shape, are considered. These shapes include spherical(Fe_3O_4), cy.indrical(Au), and platelet(Zn) configurations. The combination approach is utilized to evaluate the phy.ical and thermal characteristics of the trihy.rid and hy.rid nanofluids, excluding the thermal conductivity.and dy.amic viscosity. These two properties are inferred by.means of the interpolation method based on the volume fraction of nanoparticles. The governing equation is transformed into a dimensionless form, and the Adomian decomposition Sumudu transform method(ADSTM) is adopted to solve the conundrum of a moving fin immersed in a trihy.rid nanofluid. The obtained results agree well with those numerical simulation results, indicating that this research is reliable. The influence of diverse factors on the thermal overview for vary.ng noninteger values of γ is analy.ed and presented in graphical representations. Furthermore, the fluctuations in the heat transfer concerning the pertinent parameters are studied. The results show that the heat flux in the presence of the combination of spherical, cy.indrical, and platelet nanoparticles is higher than that in the presence of the combination of only.spherical and cy.indrical nanoparticles. The temperature at the fin tip increases by.0.705 759% when the value of the Peclet number increases by.400%, while decreases by.11.825 13% when the value of the Hartman number increases by.400%.
