The need to provide food and better living to the exp loding world population promises to exacerbate climate change due to the h igh carbon cost per calorie and non-biodegradable products. Plant-based fo ods and formulations offer promising alternatives\; however\, their suitab ility as sustainable substitutes will require emulating properties\, proce ssing\, and functionalities of the animal- and fossil-fuel-based products. \n\nFlow behavior\, stringiness\, spinnability\, and printability of formu lations are often assessed qualitatively by dripping from a nozzle or a la dle or by stretching a liquid bridge between two surfaces (thumb and foref inger or between parallel plates). The handy tests examining the pinching time of a columnar neck undergoing spontaneous capillarity-driven pinching and extensional flows correlate better with stringiness and dispensing be havior than shear rheology characterized using torsional rheometers. Howev er\, well-documented challenges arise for the quantitative characterizatio n of extensional rheology response\, leaving unanswered questions about th e influence of macromolecular properties on rheology\, processing\, and se nsory perception\, thus hampering the search for sustainable alternatives. \n\nHere\, we show that the dripping-onto-substrate (DoS) rheometry protoc ols we developed enable the characterization of extensional rheology of th e polymer solutions and multicomponent formulations. We investigate the in fluence of polysaccharide thickeners on the rheology and fizzics of plant- based milk emulsions\, real and vegan mayo\, and model paints and cosmetic s. We find that the pursuit of practically motivated problems concerning r heology\, shelf-life\, and consumer perception of sustainable formulations involves fundamental problems in soft matter physics and fluid mechanics. We probe the influence of ingredient-specific interactions and dynamics b y elucidating the impact of significant stretching\, unraveling\, and orie ntation of polymers and proteins (or drop/bubble deformation and breakup) in response to nonlinear extensional flows. A deeper understanding of pinc hing dynamics and the governing mechanical quantities compels exploration and advances into the physics and mathematics of self-similarity\, finite- time singularity\, coalescence and spreading kinetics\, stretched polymer physics\, and scaling or dimensional analysis.\nBio\nVivek Sharma\, Ph.D.\ nAssociate Professor\, Chemical Engineering\nUniversity of Illinois Chicag o\nDr. Vivek Sharma is an Associate Professor of Chemical Engineering at the University of Illinois Chicago (UIC). His Soft Matter ODES-lab (optics \, dynamics\, elasticity\, and self-assembly laboratory) develops distinct ive experiments and theories to analyze interfacial and nonlinear flows\, colloidal and surface forces\, optics\, shear and extensional rheology\, a nd the processability of industrial and biological soft matter. His resear ch program exploits and advances surfactant\, proteins\, &\; polymer ph ysics\, fizzics (the science of drops\, bubbles\, jets\, foams\, and emuls ions)\, and fluid mechanics to facilitate macromolecular engineering of fo rmulations\, including coatings\, fibers\, cosmetics\, and plant-based foo ds. Vivek also publishes as a poet\, an essayist\, and a translator.\n\nVi vek received a B. Tech (Textile) from IIT Delhi and an M. S. (Polymer Scie nce\, 2003) from the University of Akron. He obtained his M. S. (Chemical Engineering\, 2006) and Ph. D. (Polymers/MSE\, 2008) from Georgia Tech. Fo llowing post-doctoral research in Mechanical Engineering at MIT\, he estab lished ODES-lab at UIC in November 2012. Vivek was selected as the Disting uished Young Rheologist by TA Instruments in 2015 and won the 3M Non-Tenur ed Faculty Award in 2019. At UIC\, he received the College of Engineering (COE) Teaching Award in 2017 &\; 2023 and the COE Advising Award in 20 22. Vivek is the winner of the 2023 John H. Dillon Medal awarded by the A merican Physical Society.
