for modulus decay. A borax threshold near 0.1250 wt % delineated weak from strong gel regimes. Steady shear measurements revealed a three-region flow curve, including shear-thickening and shear-thinning regions that depended on temperature and cross-link density. All formulations deviated from the Cox-Merz rule at high shear. These findings support predictive design of thermoresilient borate-guar gels for energy and high-temperature applications.
