Melting aspects in flow of second grade nanomaterial with
homogeneous–heterogeneous reactions and irreversibility phenomenon: A
residual error analysis
- Authors: Faris Alzahrani, Muhammad Ijaz Khan
  Abstract: Progress in Reaction Kinetics and Mechanism, Volume 47, Issue , January-December 2022.
  Here, we scrutinize the entropy analysis in magnetohydrodynamic flow of second-grade nanomaterials with melting effect subject to stretchable bended surface. Heat attribution is modeled through first law of thermodynamics with radiation effect. Major physical effect of random and thermophoretic motion is also addressed. Feature of irreversibility (entropy rate) analysis is also discussed. Isothermal cubic autocatalyses chemical reaction at catalytic surface is discussed. Nonlinear dimensionless differential system is developed through adequate transformation. Optimal homeotypic analysis method (OHAM) is employed to construct convergent solution. Influence of physical variables on entropy rate, fluid flow, concentration, and thermal field is discussed. An augmentation in fluid flow is noticed through curvature variable, while reverse effect holds for magnetic variable. A reverse effect holds for fluid flow and thermal field through melting variable. Entropy analysis is augmented with variation in melting variable. Reduction occurs in concentration through thermophoretic variable, while an opposite effect holds for thermal field. An increment in melting variable leads to reduced concentration. Larger estimation of radiation variable improves entropy analysis.

- Authors: Meng Ding, Fan Yang, Qingquan Lv, Qiongfang Liu
  Abstract: Progress in Reaction Kinetics and Mechanism, Volume 47, Issue , January-December 2022.
  In this current work, two fresh transition metal coordination polymers (CPs) have been created with the reaction between terphenyl-3,3″,5,5″-tetracarboxylic acid (H4L), the symmetrical rigid carboxylic acid ligand and the relevant metal salts under the reaction conditions of solvothermal, and the chemical compositions of the compounds respectively are {[Cu2(TPTC) (DMF)2(H2O)]·2DMF·2H2O} (2) and {[Zn (TPTC) (1,2-bimb)2]·4(H2O)}n (1, bimb = 1,2-bis((1H-imidazol-1-yl)methyl)benzene). Moreover, the prevention and nursing values of the compound on postoperative infection was explored and their corresponding mechanism also was investigated. Firstly, enzyme linked immunosorbent assay kit (ELISA) was employed to detect the release of inflammatory cytokines into plasma. Additionally, the expression of the bacterial survival genes was determined via exploiting the real time reverse transcription-polymerase chain reaction (RT-PCR) after treated with the compound.

A new mixed-ligand Mn(II) coordination polymer: Protective and nursing

- Authors: Yan Yang, Sheng-Mei Zhang, Yi-Qian Zhang, Liang Chen, Tao Xiong
  Abstract: Progress in Reaction Kinetics and Mechanism, Volume 47, Issue , January-December 2022.
  In the present study, via using the mixed-ligand synthesis approach, a new Mn(II)-containing coordination polymer (CP) with the chemical formula of {[Mn3(timb)2(SO3–IPA)2(H2O)2]·8H2O}n (1) has been successfully prepared via reaction of MnCl2·4H2O with the tripodal linker 1,3,5-tris(2-methylimidazole-1-yl)benzene (timb) and aromatic dicarboxylic acid ligand –SO3 group functionalized isophthalic acid (H2IPA) ligand. Furthermore, the biological activity of the new compound on renal calculus was assessed, and the related mechanism was explored as well. The Calcium Colorimetric Assay was conducted and the concentration of Ca2+ in urine was determined. The western blotting assay was conducted and the expression levels of the osteopontin (OPN) in the distal tubule were measured. Molecular docking simulation revealed that the carboxyl, iminazole, and sulfonate groups were all involving into the binding interactions with the target protein, and therefore exhibited strong biological activity.

Effect of nano bentonite on direct yellow 50 dye removal; Adsorption
isotherm, kinetic analysis, and thermodynamic behavior
- Authors: Ahmed S. Mahmoud
  Abstract: Progress in Reaction Kinetics and Mechanism, Volume 47, Issue , January-December 2022.
  Developing countries suffering from the toxicity of different industrial effluents especially dyes. This study successfully prepared and characterized nano-bentonite for anionic dye removal (DY 50). The prepared nanoparticles were characterized by X-Ray Diffraction (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscope (SEM), EDAX analysis, FT-IR, and TGA and the obtained results indicated the formation of nanoparticles with an average size of 15 nm. The effect of different operating conditions was studied using different pH, dose, contact time, temperature, and initial DY 50 concentrations. The obtained results indicated that nano bentonite was able to adsorb about 78.3 and 100% for initial concentrations of 100±8.1 and 20 ±1.62 mg/L, respectively. The optimum removal conditions were observed at acidic media (pH 3) using sorbent material dosage 1 g/L for 45 min and 30°C. The adsorption isotherm, kinetic analysis, and thermodynamic behavior were studied by using linear equation form, and the adjusted R2 was compared to detect the preferred models. The adsorption isotherm indicated that heterogeneous, as well as multilayer adsorption, plays an important role in the removal of dye. Kinetic studies indicated the chemisorption interaction between sorbed and adsorbed molecules. Thermodynamic behavior indicated the reaction is exothermic with ∆H equal to −5.24 KJ/mol and ∆S equal −74.2 J/K.mol. Finally, this study strongly recommended using nano bentonite for DY 50 removal from an aqueous solution. The RSM relations show significant relations in all removal models with p-value

Computational analysis of induced magnetohydrodynamic non-Newtonian

- Authors: Muhammad Imran Anwar, Hina Firdous, A.Al Zubaidi, Nadeem Abbas, Sohail Nadeem
  Abstract: Progress in Reaction Kinetics and Mechanism, Volume 47, Issue , January-December 2022.
  In the current article, induced magnetic field applied on second-grade fluid flow under variable thermal conductivity by an exponentially stretching sheet is taken into account for current analysis. The chemical reaction and viscous dissipation effects under the influence of thermophoresis and Brownian motion are considered on an exponentially stretching sheet. With the above assumptions, a mathematical model was developed in terms of partial differential equations by using the boundary-layer approximations. Similarity transformations in terms of ordinary differential equations considerably simplified this system. The dimensionless system was solved by a numerical procedure, the bvp4c method. The effects of involving physical parameters are presented through graphs and tables. The obtained numerical outcomes of the skin friction coefficient, the Sherwood number, and the Nusselt number are also highlighted in the tabulated form. It is concluded that the velocity and concentration profiles increased due to higher values of material parameter.
