In this study, the performance of chitosan based semi-IPN nanocomposite hydrogels for the adsorptive removal of basic violet 14 (BV14) from aqueous solution has been explored. Batch adsorption studies were conducted to determine the effect of various parameters on BV14 adsorption, and optimum values were reported as pH of 8, the adsorbent dosage of 0.025 g, initial BV14 concentration of 5 mg L–1 and contact time of 90 min at a temperature of 25 °C.

The interaction between small molecules and neutral soluble dietary fiber is one of the proposed mechanisms determining the bioavailability of these components in the small intestine. However, the weak nature of these interactions makes it difficult to find an analytical method sensitive enough to detect them.

Paper "Investigating the structure and thermodynamic properties of silicene materials when cooling fast by molecular dynamics simulation" presents the results of two-dimensional silicene cooling studies by MD simulation with a sample of 6400 atoms. The Silicene model was run on Lammps software with a StillingerWeber interaction potential. Silicene after melting to 3500K, it is cooled at a rate of 1013 K/s to a temperature of 300K. Investigation of the dependence of energy on temperature shows a jump in the average total energy of molten silicene at the temperature T = 1965K.

The influence of heterogeneity, however, cannot be studied experimentally. In this study, we employed two reversed phase columns with different retention mechanisms to show that by serially coupling the columns, the obtained thermodynamic parameters are not related to the results obtained on the respective individual columns.

The moment method in the statistical dynamics is used to study the thermodynamic properties of metals taking into account the anharmonicity effects of the lattice vibrations. The effective pair potentials work well for the calculations of metals. For obtaining better agreement of the thermodynamic quantities of metals like Nb, the many body potentials derived from the microscopic electronic theory are used. The theoretical calculations of the thermodynamic properties are in good agreement with the corresponding experimental results.
