“…The values of Δ S o and Δ H o were calculated using the slope and origin intercept of a graph of ln K eq versus 1/ T after calculating the thermodynamic equilibrium constant for the Gibbs free energy at various temperatures. Table S4’s positive entropy change (Δ S o = 75.84 J/mol K) and positive enthalpy change (Δ H o = 19.92 kJ/mol) values demonstrate that the absorption process is disrupted by the increased motility of the TC molecules in solution because the adsorption process is endothermic and the irregularity rises with temperature. , …”

In the present study, a nanocomposite adsorbent based on mesoporous silica nanotubes (MSNTs) loaded with 3aminopropyltriethoxysilane (3-APTES@MSNTs) was synthesized. The nanocomposite was employed as an effective adsorbent for the adsorption of tetracycline (TC) antibiotics from aqueous media. It has an 848.80 mg/g maximal TC adsorption capability. The structure and properties of 3-APTES@MSNT nanoadsorbent were detected by TEM, XRD, SEM, FTIR, and N 2 adsorption− desorption isotherms. The later analysis suggested that the 3-APTES@MSNT nanoadsorbent has abundant surface functional groups, effective pore size distribution, a larger pore volume, and a relatively higher surface area. Furthermore, the influence of key adsorption parameters, including ambient temperature, ionic strength, initial TC concentration, contact time, initial pH, coexisting ions, and adsorbent dosage, had also been investigated. The 3-APTES@MSNT nanoadsorbent's ability to adsorb the TC molecules was found to be more compatible with Langmuir isothermal and pseudo-second-order kinetic models. Moreover, research on temperature profiles pointed to the process' endothermic character. In combination with the characterization findings, it was logically concluded that the 3-APTES@MSNT nanoadsorbent's primary adsorption processes involved interaction, electrostatic interaction, hydrogen bonding interaction, and the pore-fling effect. The synthesized 3-APTES@MSNT nanoadsorbent has an interestingly high recyclability of >84.6 percent up to the fifth cycle. The 3-APTES@MSNT nanoadsorbent, therefore, showed promise for TC removal and environmental cleanup.

“…Density measurement: In this investigation, the density (ρ) of all liquid mixtures and pure liquids was measured at 303.15 using a 105 mL double-arm pycnometer as reported by Nikkam et al [20,21]. In order to calibrate the pycnometer, water with a conductivity and a density of 995.61 kg/m 3 was employed.…”

Over the complete composition range of mole fractions, densities and ultrasonic velocities of binary liquid mixtures of dimethyl malonate with o-xylene, p-xylene and m-xylene were investigated at 303.15-318.15 K. These parameters were chosen to investigate the impact of substituents and specific locations on several thermodynamic characteristics of binary mixtures. The deviation in adiabatic compressibility (∆βad), excess molar volume (VE) and excess intermolecular free length (LfE) were estimated using the experimental measurements. These extraneous parameters are fitted to a polynomial equation of the Redlich-Kister type. Along with the obtained parameter values, the standard deviation (σ) was also determined.
