LAOS Rheology: a start-to-finish guide
Simon Rogers, Chemical and Biomolecular Engineering, University of Illinois at Urbana-Champaign
Course Description
Large amplitude oscillatory shearing (LAOS) is a popular method of probing the transient nonlinear rheology of a wide range of soft materials. The ability to tune
the strength of the flow with the amplitude and the timescale with the frequency allows LAOS to stand in for a variety of real-world applications. While it’s an
easy test to perform, how to understand the results obtained from such tests has been the subject of study for decades. This course will provide historical context
of our understanding of LAOS as well as teach participants the fundamental rheological concepts behind the protocol, the dimensionless groups that are often used to
describe LAOS, how to perform experiments in ways that allow maximum extraction of information, and how to interpret results. A particular emphasis of the course is
to show how connections between LAOS and responses to other protocols. Attendees will benefit from pre-existing familiarity with the concepts of stress, viscoelasticity,
non-Newtonian rheology, and rheometry. The course will include experimental demonstrations of LAOS measurements of materials that yield and how the obtained data can be
analyzed and used for constitutive model determination.

Simon Rogers
is Associate Professor of Chemical Engineering at the University of Illinois at Urbana-Champaign. Before joining the faculty at UIUC, he received his
B.Sc., B.Sc. (Hons), and PhD in Physics from Victoria University of Wellington, in New Zealand. He performed postdoctoral research at FORTH in Crete,
Forschungzentrum Juelich in Germany, and at the University of Delaware. Prof. Rogers’ research focuses on understanding the fundamental physics behind
time-dependent phenomena exhibited by soft condensed matter systems for biomedical, energy, and environmental applications. Toward this aim, a particular
focus of the Rogers lab is the integration of rheological, structural and flow measurements to monitor material processing in situ. Rogers’ research has
been recognized with early career awards from the National Science Foundation, American Chemical Society, and The Society of Rheology.
Automated Rheology and Application to Multi-methods Measurements
Jeffrey Richards, Chemical and Biological Engineering, Northwestern University
Thibaut Divoux, CNRS / ENS de Lyon
Course Description
Recently deployed open software concepts in commercial rheometers have made possible automation of rheological experiments without interaction with the graphical
user interface. In this short course, we will illustrate how Python can be leveraged to control a rheometer and how data streams from the rheometer can be utilized
to perform multi-method experiments, synchronizing the activities of the rheometer and other test equipment. This short course has broad applicability to a variety
of in situ rheometric techniques that couple rheology with other measurement tools to probe the properties of samples under test. Attendees will benefit from
pre-existing familiarity with programming concepts such as instrument control and data acquisition. For that audience, this course will serve as a first introduction
to interacting with an Application Programming Interface. A particular emphasis of the course is the illustration of multi-methods measurements using rheo-electric
measurements, where impedance measurements are made on a sample at the same time as rheology is measured. Our focus will seek to understand how the formulation and
processing of complex fluids whose electrical properties change dramatically under different flow conditions (e.g., lithium-ion battery slurries, carbon black gels,
graphene dispersions, etc.) can be informed by these measurements. This demonstration will show how impedance measurements on slurries subjected to shear in a
rheometer can be used to overcome the challenges related to characterizing the rheology of these slurries. A special emphasis will be placed on the impact that
flow history has on the electric impedance, which is a highly sensitive probe of the slurry microstructure and its response to processing. Impedance correction
protocols will be reviewed, and standard rheological protocols for slurry characterization discussed. Theories and scaling laws will be reviewed connecting elasticity
to electrical behavior.

Thibaut Divoux,
a CNRS research scientist since 2012, specializes in soft matter physics and experimental rheology. His research has generated original insights on amorphous soft
materials both from a fundamental perspective, and in various industrial sectors including pharmaceuticals (e.g., agarose gels), food (e.g., yoghurts), construction
(e.g., tile adhesive), and energy storage (e.g., conductive suspensions of carbon black or graphite oxide). His expertise encompasses complex fluids, dense suspensions,
gels and soft composites that he investigates by rheometry coupled with local techniques such as velocimetry, dielectric measurements, and IR spectroscopy. Additionally,
he performs local mechanical tests using atomic force microscopy, micro- and nano-indentation to understand how local mechanical properties translate in the macroscopic
response of these viscoelastic materials. He was awarded the 2018 Metzner Prize of the Society of Rheology for his work on the shear-induced yielding transition in Soft
Glassy Materials. Since 2023, he is serving as co-director of the GDR SoPhy, aiming to unite national and international research efforts in physics of soft precursors
for hard materials with over 300 members spread in 60 laboratories.
