Two self-healing-type supramolecular Ni(II)-metallogels are achieved. The choice of proper low-molecular-weight organic gelators such as trans-butenedioic acid (i.e., trans-BDA) and cis-butenedioic cis-BDA) triethylamine in N,N′-dimethylformamide solvent facilitates the metallogelation process. Through rheological investigations mechanical robustness viscoelastic properties synthesized metallogels explored. An in-depth exploration thixotropic behavior also supports their self-healing...
The generation of solvent-directed self-healing supramolecular Ni(II) metallogels glutaric acid (i.e., Ni-Glu-DMF and Ni-Glu-DMSO) is described in this article. Polar aprotic solvents like N,N'-dimethylformamide (DMF) dimethyl sulfoxide (DMSO) are separately entrapped into the Ni(II)-acetate salt acid-mediated networks to attain semisolid flexible scaffolds. gel nature fabricated materials experimentally proven through different rheological tests such as amplitude sweep, frequency...
Tetracarboxylic acid-directed formation strategy of Zn(II)-metallogel has been achieved through supramolecular interactions among gel-forming Zn(II) acetate dihydrate, pyromellitic acid and N,N′-dimethyl formamide (DMF). Role as low molecular weight gelator in forming stable established the work. Mechanical stability characterized several rheological analyses including frequency sweep, strain time sweep (i.e., thixotropic analysis), Creep recovery tests. The morphological feature xerogel...
Ni(II)-source and terephthalic acid (TA)-based solvent-directed supramolecular metallogels (i.e., Ni-TA-DMF Ni-TA-DMSO) are achieved in diverse polar-aprotic solvent media involving DMF DMSO. The Zn(II) coordination polymer-based gel composite (CPG-composite) of Ni(II) is also originated by utilizing a acid-directed chemically functionalized Zn(II)-based two-dimensional polymeric network. mechanical flexibility well-characterized through rheology. Ni-TA-DMSO offer extensive self-repairing...

α-Ketoglutaric acid-based supramolecular Zn(II) metallogels in N,N′-dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) solvent (i.e., Zn-α-Glu-DMF Zn-α-Glu-DMSO) were successfully achieved. Zinc(II) acetate salt α-ketoglutaric acid directed a three-dimensional noncovalent network individually entrapped with to accomplish their respective semisolid flexible metallogel frameworks. The gel features of these synthesized materials verified by rheological experiments such as amplitude sweep...
The Zn(II)-supramolecular metallogel (i.e., Zn-Py) of 2,6-pyridinedicarboxylic acid was prepared through the addition a metal source and as low molecular weight gelator. Zn-Py encapsulated N,N′-dimethylformamide gel-immobilized polar aprotic solvent media. mechanical features synthesized were investigated. thixotropic behavior also analyzed. microscopic feature imaged FESEM TEM studies. EDS pattern ratified role different gel-building chemical constituents. stimuli responsiveness tested....
The processing volume of bioengineering operations requires flow properties algal mass for effective techniques. Chlorella Vulgaris microalgae cultured at 25 °C in Tap media under continuous illumination was considered. It showed an exponential phase growth up to 8 days and then a stationary from 15 days. rheological biomass during the represented power law model. Microscopic analysis influence shearing on variation structure clusters complete cell separation. supported microscopy showing...
Molecular self-assembly assisted self-healing supramolecular metallogels of azelaic acid with cobalt(II)-, nickel(II)-, and zinc(II)-based metal acetate salts were successfully fabricated. Individually, N,N′-dimethylformamide dimethyl sulfoxide immobilized within these distinctly synthesized soft-scaffolds to attain their semisolid viscoelastic nature. Rheological experiments such as amplitude sweep, frequency thixotropic measurements executed for ratify gel features. The different extents...
Abstract Coal water slurries (CWS) were proposed as a substitute for the fuel oils century ago. As there is huge demand energy, it necessary us to use such concepts with good understanding of alternative fuels. CWS depends on physio-chemical properties coal and rheological slurry, obtained from Dugda washery, Jharkand, India subjected examination. These coals are ground segregated according sizes samples prepared. The prepared tested their first. various examined rheology by varying...
The present study highlights the possible utilization of polymer blend polyacrylamide and xanthan gum for an enhanced oil recovery application. A detailed investigation was carried out to examine effect alkali high-performance surfactants on solution's rheological properties emulsion stability characteristics. Besides, alteration in flow characteristics polymeric solutions corresponding reservoir conditions examined. application blends seems be promising based study, it shows higher...
Abstract In lab-developed micromachining facility has been utilized to fabricate conical micro dimple textured surfaces of different density on the Ti6Al4V implant surface improve properties for higher biocompatibility and osseointegration rate. The topography, roughness, quality, shape, size formed textures were analyzed by cross-sectional form measurement using probe-type contact profilometer FESEM (Field Emission Scanning Electron Microscope) analysis.
