The impact of magnetization is reported for the imposed of applied magnetic field along the normal direction of the flow. Additionally, the behavior of thermal radiation and the effect of binary chemical ration are implemented in the energy and concentration equation respectively. It is superimposed that both the channel walls are uniformly heated, and it is also assumed that concentration of the nanoparticles near the walls is considered as constant. However, the Cartesian coordinate system is imposed to describe the proposed designed flow problem. The formulated problem governed by nonlinear coupled partial differential equations is generalized and renovated to corresponding nondimensional form by implementing appropriate similarity rules. Further, the transformed equations are solved numerically using Runge-Kutta fourth order accompanied by shooting technique. The physical behavior of the standard factors involved in the problem is displayed graphically. Validation of the result is presented with an earlier study which shows a good correlation as well as convergence analysis of the proposed methodology. Further, the important outcomes of the proposed study are deployed as follows: the velocity distribution retards for the enhanced Reynolds number significantly; however, the Brownian motion is treated as a controlling parameter for the fluid temperature and reverse impact observed in case of fluid concentration.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div><p>• The Buongiorno model nanofluid flow within a converging and diverging channel inclined with the plane walls is analysed.</p><p>• The behaviour of not only thermal radiation but also the effect of binary chemical ration is implemented.</p><p>• It is superimposed that both the channel walls are uniformly heated and it is also assumed that concentration of the nanoparticles near the walls is considered as constant.</p><p>• The transformed equations are solved numerically using Runge-Kutta fourth-order accompanied by shooting technique.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"302 9","pages":"1337 - 1352"},"PeriodicalIF":2.2,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141194820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the proportions of simulation were used to prepare thermoplastic starch films, which were subsequently subjected to examinations such as DSC, XRD, FT-IR, SEM, and mechanical property testing. Comparative analysis of the simulation data from the three systems and the properties of the manufactured thermoplastic starch (TPS) established that the diverse functional groups of plasticizers significantly influenced starch plasticization. In different plasticizer functional group types, it was observed that hydroxyl groups in EG and amino groups in EDA predominantly form hydrogen bonds with hydroxyl groups in starch molecular chain.

Varying the amounts of shell monmer and crosslinking agents resulted thick, sphere-shaped shells with homogeneous morphology, which protects the core polymer and enabling controlled release. Structural and morphological properties are characterized using Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (H¹NMR), dynamic light scattering (DLS), and scanning electron microscope (SEM) imaging.

Thermal testing indicates heat resistance up to 300 °C, suitable for enhanced oil recovery (EOR) applications. Rheological tests determine an optimal 30-day release for the PNIPAM core, with the CS polymer showing increased viscosity under harsh conditions. The colloidal stability model estblished by Derjaguin, Landau, Verwey, and Overbeek (DLVO theory) and experimental results demonstrate good stability and energy barriers at room temperature, but decreased stability and increased agglomeration at higher temperatures.

The high aspect ratio of synthetic fluorohectorite clays allows for investigation of liquid crystalline orientational order for relatively large nanosheet spacings, in the range which can produce structural coloration, thus providing two handles for determining the nanosheet spacings: SAXS and visible color. Various clay concentrations were investigated, and good agreement with previous work on structural coloration from such suspensions was obtained. Particular attention is given to the confinement caused by the container geometry, where both cylindrical and flat confinements were investigated. In both cases, the SAXS data suggest coherent regions that have a nematic inter-orientational distribution that surprisingly is linked to the container geometry, which apparently determines the efficiency of packing of the suspension. For both geometries, the analysis suggests that these coherent regions have a 1D lamellar periodic intra-structure with uniform nanosheet spacing determined by the clay concentration and a typical correlation length in the range of 200 to 500 nm.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"21 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141169328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
