In the wake of biomimicry, I will discuss several strategies aiming to harness mechanical instabilities in flowing liquids, e.g. coiling, droplet formation, digitation, drainage, capillary suction, and use the regular shapes and universally self-organized patterns they naturally produce as templates for materials design. These flows are "frozen" as the liquids we use solidify into solids, e.g., through curing, cooling or evaporation. The shapes and patterns they form are universal and transcend the traditional divisions between scientific fields or even between living and inert matter. I will show that these similarities result from the mathematical analogies in the rules that govern pattern formation. In turn, I will demonstrate how to compose with these rules to augment our manufacturing capabilities, e.g. in soft robotics.</p> <p><strong>Biosketch</strong><br> PT Brun received his bachelor’s degree in mechanical engineering from Ecole Polytechnique in 2008 and his master’s degree in advanced chemical engineering from the University of Cambridge in 2009. He then received his PhD&nbsp;in mechanical engineering from Sorbonne University in 2012 for work on the dynamics and instability of viscous and elastic threads. Brun&nbsp;was a postdoctoral fellow at EPFL, specializing in interfacial fluid mechanics and instabilities. In 2014, he joined MIT as an instructor in applied mathematics before moving to Princeton, where he has been a faculty member in the department of chemical and biological engineering since 2017. Brun&nbsp;is the recipient of the 2020 NSF CAREER Award and the 2023 APS Early Career Award in soft matter research. His curiosity-driven research combines experimental investigations and the quantitative modeling of fluid and elastic processes in soft materials. He is best known for his work on interfacial flows and pattern-forming instabilities in the context of solidifying liquids and his studies on elastic rods and morphing materials. While the epicenter of his work is fundamental, his research naturally connects to critical societal challenges, e.g., developing new manufacturing paradigms and facilitating the distribution of soft robots into our daily lives.</p></div> </div> </div> </div> </div> <h2> <div class="paragraph paragraph--type--ucb-related-articles-block paragraph--view-mode--default"> <div>Off</div> </div> </h2> <div>Traditional</div> <div>0</div> <div>On</div> <div>White</div> Sun, 19 Mar 2023 15:46:18 +0000 Anonymous 3355 at /chbe Patten Seminar Series: Aditya Khair, Nov. 29 /chbe/2022/09/12/patten-seminar-series-aditya-khair-nov-29 <span>Patten Seminar Series: Aditya Khair, Nov. 29</span> <span><span>Anonymous (not verified)</span></span> <span><time datetime="2022-09-12T11:22:35-06:00" title="Monday, September 12, 2022 - 11:22">Mon, 09/12/2022 - 11:22</time> </span> <div> <div class="imageMediaStyle focal_image_wide"> <img loading="lazy" src="/chbe/sites/default/files/styles/focal_image_wide/public/article-thumbnail/khair_headshot61.jpg?h=9315c8e1&amp;itok=xlt_UTzF" width="1200" height="600" alt="Aditya Khair"> </div> </div> <div role="contentinfo" class="container ucb-article-categories" itemprop="about"> <span class="visually-hidden">Categories:</span> <div class="ucb-article-category-icon" aria-hidden="true"> <i class="fa-solid fa-folder-open"></i> </div> <a href="/chbe/taxonomy/term/78"> News </a> </div> <div role="contentinfo" class="container ucb-article-tags" itemprop="keywords"> <span class="visually-hidden">Tags:</span> <div class="ucb-article-tag-icon" aria-hidden="true"> <i class="fa-solid fa-tags"></i> </div> <a href="/chbe/taxonomy/term/4" hreflang="en">News</a> <a href="/chbe/taxonomy/term/281" hreflang="en">Seminar</a> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="imageMediaStyle large_image_style"> <img loading="lazy" src="/chbe/sites/default/files/styles/large_image_style/public/article-image/khair_headshot61.jpg?itok=ZSQKZEV7" width="1500" height="1500" alt="Aditya Khair"> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> <div><h2>Seminar:&nbsp;Nonlinear Electrophoresis of Colloidal Particles</h2> <p><strong>Speaker</strong>:&nbsp;Aditya Khair, Professor of Chemical Engineering, Carnegie Mellon University</p> <p><strong>Host</strong>:&nbsp;Ankur Gupta</p> <p><strong>Seminar Abstract</strong><br> The past decade has witnessed a surge of interest in nonlinear electrophoresis of charged colloidal particles in aqueous electrolytes. Here, the word "nonlinear" refers to the fact that the ratio of the electrophoretic speed of the particle to the magnitude of the applied electric field—the electrophoretic mobility—is not independent of field strength. This is in stark contrast to the vast majority of work on (linear) colloidal electrophoresis over the last century, where the mobility is assumed to be a material property dependent only on the particle-electrolyte combination. In this talk, Khair&nbsp;will first review various experimental measurements of the field-dependent mobility. He will then discuss theoretical approaches to predicting the nonlinear mobility, including asymptotic schemes in the common thin-Debye-layer limit and our own recent computations via direct numerical simulation of the full electrokinetic equations. Khair will conclude with suggestions for future work in this evolving area of colloid science.</p> <p><strong>Biosketch</strong><br> Aditya Khair is a professor of chemical engineering at Carnegie Mellon University (CMU).

However, the structure-to-function relationship and the physics describing the behavior of these polymer systems are, in general, not well understood. For example, almost all proteins have a specific three-dimensional structure that maintains its specific activity in the cell. One class of phase separating proteins, which has flown under the radar for decades, do not. They are referred to as intrinsically disordered proteins (IDPs). Their role in the cell appears to be to spontaneously associate with other proteins and nucleic acids in phase separated compartments called ‘membraneless organelles’ to activate them collectively. This is an important function to include in the design of a synthetic cell and for integration with cellular regulatory systems.</p> <p>Our work explores how we can leverage polymer physics combined with the blueprint provided by the cell to engineer synthetic membraneless organelles comprising phase separated protein/DNA/RNA components in microdroplets. Our experimental results characterizing the morphology and composition of these liquids are interpreted by simple mean field Flory-Huggins equilibrium thermodynamics combined with formalisms describing the dynamics of phase separation via Cahn-Hilliard and Lattice Boltzmann theories. Potential broader impacts of this work include understanding how these interactions affect the regulation of gene expression and cell metabolism, understanding how dysfunctional interactions are linked to neurodegenerative disorders, and the design of synthetic cellular systems to create membraneless organelles to control a variety of biological processes at the molecular level.</p> <div class="ucb-box ucb-box-title-left ucb-box-alignment-right ucb-box-style-fill ucb-box-theme-lightgray"> <div class="ucb-box-inner"> <div class="ucb-box-title">If you go</div> <div class="ucb-box-content"> <p><strong>Who:</strong> Everyone welcome<br> <br> <strong>What:&nbsp;</strong>Nick Carroll, Assistant Professor of Chemical and Biological Engineering, University of New Mexico; Patten Seminar Series&nbsp;</p> <p><strong>When:</strong>&nbsp;Sept. 27, 2022,&nbsp;2:45-&nbsp;3:45&nbsp;p.m</p> <p><strong>Where: </strong>JSCBB A108</p> <p><a href="/chbe/research/news/department-seminar-series" rel="nofollow">More information </a> </p><p><a href="mailto: chbepattenseminar@colorado.edu" rel="nofollow">Questions about this seminar</a></p> </div> </div> </div> <strong>Biosketch</strong><br> Nick Carroll received his BS and PhD&nbsp;in chemical engineering from the University of New Mexico.

Current polymerization processes do not offer much potential for efficiency improvements and energy demand reduction. Additionally, only mechanical recycling is employed at scale, which has limited life cycles due to contamination and degradation of the polymer. Thus, the most promising decarbonization options for the U.S. plastic industry involve system-wide changes and the integration of a bio-/waste-based supply chain with a plastic-to-plastic circular economy loop based on innovative recycling techniques to recover the plastic waste. The Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment (BOTTLEâ„¢) Consortium is a U.S.&nbsp;Department of Energy multi-organization research consortium focused on developing new chemical upcycling strategies for today's plastics and redesigning tomorrow's plastics to be recyclable-by-design (RBD). This talk will highlight flagship BOTTLE technologies in low-energy plastic deconstruction, upcycling strategies for the waste intermediates, and promising RBD polymers that may challenge the current plastic industry.</p> <p><strong>Biosketch</strong><br> Kat Knauer is a polymer scientist who has dedicated her scientific career to solving the plastic waste problem. She has a PhD in polymer science and engineering from the University of Southern Mississippi and completed the BASF PhD Leadership Development Program (LDP) in 2018 before taking a senior scientist role in BASF’s plastics division. Her research efforts focused on advanced recycling technologies which ultimately led her to leading materials innovation R&amp;D at Novoloop (formerly BioCellection), a San Francisco Bay area chemical recycling startup. Recently, Knauer joined the National Renewable Energy Laboratory (NREL) as the chief technology officer&nbsp;of the Bio-Optimized Technologies to keep Thermoplastics out&nbsp;of Landfills and the Environment (BOTTLE) Consortium where she is developing sustainable technologies to chemically upcycle today’s existing plastic waste streams and develop new plastics for the future that are inherently recyclable by design.</p> <div class="ucb-box ucb-box-title-left ucb-box-alignment-none ucb-box-style-fill ucb-box-theme-lightgray"> <div class="ucb-box-inner"> <div class="ucb-box-title">If you go</div> <div class="ucb-box-content"> <p><strong>Who:</strong>&nbsp;Everyone welcome</p> <p><strong>What:</strong>&nbsp;Katrina Knauer, CTO of the BOTTLE Consortium, National Renewable Energy Laboratory (NREL); Patten Seminar Series</p> <p><strong>When:</strong> Oct. 11,&nbsp;2022,&nbsp;2:45-&nbsp;3:45&nbsp;p.m</p> <p><strong>Where:</strong> JSCBB A108</p> <p><a href="/chbe/research/news/department-seminar-series" rel="nofollow">More information </a> </p><p><a href="mailto: chbepattenseminar@colorado.edu" rel="nofollow">Questions about this seminar</a></p> </div> </div> </div></div> </div> </div> </div> </div> <h2> <div class="paragraph paragraph--type--ucb-related-articles-block paragraph--view-mode--default"> <div>Off</div> </div> </h2> <div>Traditional</div> <div>0</div> <div>On</div> <div>White</div> Tue, 02 Aug 2022 01:10:00 +0000 Anonymous 3242 at /chbe Patten Seminar Series: Enrique Iglesia, Oct. 4 /chbe/2022/08/01/patten-seminar-series-enrique-iglesia-oct-4 <span>Patten Seminar Series: Enrique Iglesia, Oct. 4</span> <span><span>Anonymous (not verified)</span></span> <span><time datetime="2022-08-01T16:21:47-06:00" title="Monday, August 1, 2022 - 16:21">Mon, 08/01/2022 - 16:21</time> </span> <div> <div class="imageMediaStyle focal_image_wide"> <img loading="lazy" src="/chbe/sites/default/files/styles/focal_image_wide/public/article-thumbnail/enrique_mg_3197_full_trimmed_300_dpi.jpg?h=44addd64&amp;itok=5j1mmbzN" width="1200" height="600" alt="Enrique Iglesia in a jacket and tie"> </div> </div> <div role="contentinfo" class="container ucb-article-categories" itemprop="about"> <span class="visually-hidden">Categories:</span> <div class="ucb-article-category-icon" aria-hidden="true"> <i class="fa-solid fa-folder-open"></i> </div> <a href="/chbe/taxonomy/term/78"> News </a> </div> <div role="contentinfo" class="container ucb-article-tags" itemprop="keywords"> <span class="visually-hidden">Tags:</span> <div class="ucb-article-tag-icon" aria-hidden="true"> <i class="fa-solid fa-tags"></i> </div> <a href="/chbe/taxonomy/term/4" hreflang="en">News</a> <a href="/chbe/taxonomy/term/281" hreflang="en">Seminar</a> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="imageMediaStyle large_image_style"> <img loading="lazy" src="/chbe/sites/default/files/styles/large_image_style/public/article-image/enrique_mg_3197_full_trimmed_300_dpi.jpg?itok=P3UxDsZb" width="1500" height="2144" alt="Enrique Iglesia in a jacket and tie"> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> <div><h2>ChBE Patten Distinguished Lecturer<br> Seminar: Binding Sites and their Environment in Surface Catalysis</h2> <p><strong>Speaker</strong>: Enrique Iglesia, Distinguished Professor and Theodore Vermeulen Chair in Chemical Engineering, University of California, Berkeley; Laboratory Fellow – Pacific Northwest National Laboratory</p> <p><strong>Host</strong>: <a href="/chbe/j-will-medlin" rel="nofollow">Will Medlin</a></p> <p><strong>Seminar Abstract</strong><br> The properties of molecular species that act as intermediates and transition states and of the surface sites that bind them act in concert to select reaction channels in chemical transformations mediated by surfaces. In acid-base and oxidation catalysis on oxides, theory and experiments have uncovered unprecedented details about site requirements and mechanisms, at the level of local architectures and elementary steps, respectively. On acids, the deprotonation energy of a solid and the proton affinity of the relevant analogs of transition states determine reactivity and selectivity, because such chemistries involve proton transfer and ion-pairs at transition states. Oxidation cycles on redox-active oxides occur via elementary steps reduce metal centers via H-abstraction from C-H bonds in reactants.&nbsp; The relevant transition states involve bound di-radical pairs with O-H and C-H bonds that are nearly formed and cleaved, respectively, thus making the energies of H-binding at surface O-atoms and of C-H homolysis the relevant surface and molecular descriptors of oxidation reactivity.&nbsp; In both types of reactions, more accurate descriptions, however, require assessments of how molecular species and sites interact and delocalize electron density in stabilizing intermediates and transition states, specifically ion-pairs and di-radicals in acid and oxidation catalysis, respectively. The environments that surround the active sites complement their&nbsp; binding properties through solvation effects that can stabilize specific bound intermediates and transition states through weak concerted van der Waals or H-bonding interactions.&nbsp; Such stabilization is particularly evident when sites reside within inorganic voids of molecular dimensions or exist in contact with dense phases, such as liquids or dense adlayers. These inner and outer sphere effects on reactivity and the fidelity brought forth by solids with well-defined atomic architectures are bringing us closer to the purposeful design of catalytic surfaces.</p> <div class="ucb-box ucb-box-title-left ucb-box-alignment-right ucb-box-style-fill ucb-box-theme-lightgray"> <div class="ucb-box-inner"> <div class="ucb-box-title">If you go</div> <div class="ucb-box-content"> <p><strong>Who:</strong>&nbsp;Everyone welcome</p> <p><strong>What:</strong>&nbsp;Enrique Iglesia, Distinguished Professor and Theodore Vermeulen Chair in Chemical Engineering, University of California, Berkeley; Patten Seminar Series</p> <p><strong>When:</strong> Oct. 4, 2022,&nbsp;2:45-&nbsp;3:45&nbsp;p.m</p> <p><strong>Where:</strong> JSCBB A108</p> <p><a href="/chbe/research/news/department-seminar-series" rel="nofollow">More information </a> </p><p><a href="mailto: chbepattenseminar@colorado.edu" rel="nofollow">Questions about this seminar</a></p> </div> </div> </div> <strong>Biosketch</strong><br> Enrique Iglesia is a distinguished professor and the Theodore Vermeulen Chair in Chemical Engineering at the University of California, Berkeley and a laboratory fellow at Pacific Northwest National Laboratory.

Ware, Associate Professor, Biomedical Engineering, Materials Science, and Engineering<br> Texas A&amp;M University<br> <br> <strong>Host: </strong>Tim White</p> <p>Tuesday, April 19, 2022 - 2:45 p.m<br> JSCBB A108</p> <p><strong>Seminar Abstract</strong> </p><p>Stimuli-responsive polymers respond to their environment without requiring motors, sensors, or power supplies. These materials can replace the functions of traditional machines in conditions or at scales, such as in the human body, where traditional actuators, electronics, and batteries are difficult to employ. Here, two orthogonal strategies, one non-living and one living, to create materials that respond in a complex manner to specific environmental conditions, such as exposure to light, will be discussed. First, we will discuss controlling molecular orientation, and therefore the stimulus-response, in liquid crystal elastomers. Using processing techniques, such as 3D printing, and materials formulation strategies, shape change, geometry, and activation temperature can be precisely controlled. We will discuss the potential applications of these materials as reconfigurable structures and as artificial muscles. We will also discuss the harnessing entanglement of many shape changing polymer structures to create 3D objects that self-assemble and then disperse on command. Notably, the stimulus-response of these and many other smart materials is derived wholly from physical properties, and as a result, these materials require powerful stimuli, such as heat, to induce shape change. By comparison, the stimulus-response of living organisms can be triggered by weak physical stimuli or specific biochemicals. To bridge the gap between living cells and engineered materials, we will discuss fabricating living Baker’s yeast –hydrogel composites capable of undergoing programmed shape change. As the cells are higher modulus (~100×) than the gel, cell proliferation results in a macroscopic shape change of the composite. Importantly, genetic manipulation of the yeast enables the stimulus that induces shape change to be controlled. For example, we will discuss composites where volume change on exposure to a single biochemical (L-histidine) is 14× higher than volume change when exposed to highly similar biochemicals (D-histidine and other amino acids). These living composites may enable new strategies for medical devices like autonomous drug-delivery systems.</p> <p><strong>Biosketch</strong> </p><p>Taylor Ware is an Associate Professor in Biomedical Engineering and Materials Science and Engineering at Texas A&amp;M University.

Next, we discuss plastics upcycling. Single-use plastics impose an enormous environmental threat, but recycling, especially of polyolefins, has proven challenging. We report a direct method to selectively convert various polyolefins, including virgin materials, layered materials, and everyday plastics, to branched, liquid fuels including diesel, jet, and gasoline-range hydrocarbons, with high yields and at low temperatures in the melt. We discuss new mechanisms by which polyolefins depolymerize.</p> <p><strong>Biosketch</strong></p> <p>Dionisios (Dion) G.

We have leveraged advances in multi-modal electron microscopy to generate new insights on membrane structure and function.&nbsp; For example, we have combined the focused ion beam with scanning electron microscopy through serial sectioning to reconstruct a 3D representation of ultrafiltration membranes using for virus removal from biopharmaceutical streams.&nbsp; In addition, we have combined energy-filtered transmission electron microscopy with electron tomography from scanning transmission electron microscopy images to map the variation in density of polyamide films used in reverse osmosis membranes.&nbsp; Quantitative analyses of imaging products are key to extract mechanistic details that govern water transport and separations.&nbsp; Furthermore, we image membranes challenged with model and common foulants, to ascertain initial conditions and mechanisms for degradation of filtration performance.</p> <p><strong>Biosketch</strong> </p><p>Enrique D.

Patterned, surface-grafted polymer brushes provide spatial control over a variety of physical properties and allow for fabrication of ‘intelligent’ substrates which selectively adapt to their environment. This presentation describes recent advances in our group in using photolithography to produce topographically and chemically patterned polymer brush surfaces via surface-initiated (SI) photoinduced electron/energy transfer (PET) reversible addition–fragmentation chain transfer (RAFT) polymerization. Using this oxygen tolerant approach, organic light emitting diodes (OLEDs), anti-microbial surfaces, and anti-fogging coatings are engineered to highlight facile pathways towards advanced functional surfaces. Oxygen tolerance, mild reaction conditions, and the use of visible light make this approach user-friendly in its application for the design of patterned and functional organic thin films.</p> <p><strong>Biosketch</strong> </p><p>Christian received his Diploma in Polymer and Colloidal Chemistry from the University of Bayreuth (Germany), before working for Prof. Alexander Böker at the DWI - Leibniz Institute for Interactive Materials (RWTH Aachen University, Germany).
