Stabilizing the Exotic Carbonic Acid by Bisulfate Ion

The solvation of SOH group in hydrated HSO4−(H2O)n clusters

The S=O stretching and SOH bending peaks in the vibrational spectra of HSO4−(H2O) n, with n up to 6, are analyzed by both harmonic analysis and ab initio molecular dynamics simulation. The SOH bending mode is found to be much more sensitive to the extent of hydration and to the fluctuation of hydrogen bonds than the S=O stretching mode. The SOH donor hydrogen bond is gradually stabilized by n = 4, and further shortened up to n = 6, which is the key factor to understand the trend of evolution observed in the infrared multiple photon dissociation spectra.

Research on the New Ecological Model under the Environment of “Double Reduction” of Children’s Community Education Services

Children are the hope of building a powerful, modern-socialist state. In recent years, all social classes have paid more and more attention to children's enlightenment education, and the country began to implement the double reduction policy. As the main place for children to live and grow, the community has the responsibility and obligation to conduct the education of children. Work and effective development and utilization of community education resources can greatly meet the needs of children's growth, help children develop good behavior habits, and lay a solid foundation for future education. Through the experimental survey results, this paper discusses the theoretical basis for the development and utilization of community children's education resources under the dual emission reduction policy, puts forward the corresponding development principles, and analyzes the main strategies to improve the efficiency of social education.
