MCB Seminar;Developing the Toolkit for Investigating Multi-Organelles’ Interactome in Live Cells, March 20https://events.berkeley.edu/live/events/243494-mcb-seminardeveloping-the-toolkit-for
Host: Na Ji
 
Abstract: My presentation will highlight three recent breakthroughs in imaging, sensing, and modulating organelles’ interactome in live cells. Firstly, we address speed and throughput challenges by using a universal lipid-specific dye for ratiometric imaging of membrane-associated organelles, enabling segmentation of up to 15 structures. Secondly, we explore lanthanide-doped nanoparticles capable of up-converting infrared photons into intense visible light at the nanoscale, facilitating diverse bio-applications, including the tracking of single-molecule transport, super-resolution microscopy, nanoscale thermometry, and nanoscale optical tweezers. Lastly, we introduce nanoscale capacitive optoelectrodes for in vivo neuromodulation, offering high-efficiency optical neuromodulation with minimal side effects. These advancements enable super-resolution imaging, sensing, and modulation of single molecules and live cells in their physiological environment, providing insights into the nanoscale world inside living cells.

Designing Advanced Nanocatalysts by Looking at Atoms and Molecules on Reactive Surfaces: Nano Seminar series, March 22https://events.berkeley.edu/live/events/237676-designing-advanced-nanocatalysts-by-looking-at

Clarification of the nature of active sites at both solid-gas and solid-liquid interfaces has been a long-standing question in surface chemistry, holding paramount significance in crafting innovative catalytic materials that demand minimal energy consumption. A bimetallic Pt alloy, or mixed catalyst, is an excellent platform to uncover the contentious role of the metal–metal oxide interface because the alloyed transition metal can coexist with the Pt surface layer in the form of an oxidized species on the bimetal surface during catalytic reactions. The real-time imaging of catalytically reactive atomic sites using operando surface techniques, including ambient pressure scanning tunneling microscopy, can reveal the nature of reactive sites on the catalytic surfaces.

In this talk, I present in-situ observation results of structural modulation on Pt-based bimetal catalysts and mixed catalysts and its impact on the catalytic activity. We utilized PtNi, and PtCo that includes both single crystal and nanoparticle surfaces as model catalysts, and showed the coexistence of Pt and metal oxide leads to the enhancement of catalytic activity, indicating these metal-oxide interfaces provide a more-efficient reaction path for CO oxidation. The mixed catalysts composed of Pt nanoparticles and the mesoporous cobalt oxide exhibit the enhancement of catalytic activity while Pt is encapsulated by the oxide thin layers forming the reactive metal-oxide interfaces. In addition, we address the fundamentals of the electrocatalytic process and on locating the real active sites at the solid-liquid interface by utilizing in-situ electrochemical scanning tunneling microscopy. Overall, the atomic-scale imaging of the reactive surfaces gives rise to the design rule of advanced bimetallic and mixed catalysts.

Polar Topological Defects – Fundamentals to Applications: Nano Seminar series, April 5https://events.berkeley.edu/live/events/230393-polar-topological-defects-fundamentals-to

Topological defects such as vortices and skyrmions have recently gained significant interest in solid state materials as ferroic materials (ferromagnets and ferroelectrics) have become a test-bed to realize and control these nanoscale structures. Although this phenomenon is being investigated as a pathway to energy efficient information storage, broader applications in interaction of electromagnetic waves with such features are emerging.

In the case of ferroelectrics, boundary condition engineering is used to achieve vortices, skyrmions, and merons in low dimensional epitaxial oxide heterostructures.

In this talk, I will introduce the notion that similar phenomenology but at the atomic scale can be achieved in charge density wave phases, especially nominally semiconducting chalcogenides. I will outline my group and other groups’ efforts in showing non-trivial toroidal polar topologies at the atomic level in chalcogenides with nominally empty conduction band with d-orbital character such as 1T-TiSe2, Ta2NiSe5 and BaTiS3.

Specifically, we use X-ray single crystal diffraction as a probe for high quality single crystals of a quasi-1D hexagonal chalcogenide, BaTiS3, to reveal complex polar topologies such as vortices, and head-to-head and tail-to-tail arrangement of dipoles. Recent experiments and theoretical studies on the stability and dynamics of these features, and their broad connection to low dimensional magnets, will also be discussed. Lastly, I will outline the perspective for photonic applications of polarization textures.

Bioengineering Seminar: Surgical Bioengineering - Engineering Stem Cells and Extracellular Components for Tissue Regeneration, April 10https://events.berkeley.edu/bioe/event/217517-bioengineering-seminar-surgical-bioengineering-engine

Abstract:

This presentation is providing an overview of the ongoing research at the UC Davis School of Medicine, Center for Surgical Bioengineering (CSB). CSB focuses on engineering stem cells and biomaterials to develop novel regenerative therapies for a variety of diseases, with the focus being on the birth defect program in collaboration with the UC Davis Fetal Treatment Center and Shriners Children’s. Birth defects represent a substantial portion of pediatric morbidity and mortality. In the United States, 1 in every 33 infants is born with a congenital anomaly, and congenital anomalies comprise the largest cause of infant death. In utero surgery and stem cell therapy have the potential to revolutionize the treatment of birth defects: instead of merely treating symptoms following birth, anomalies may be treated or cured before birth. The Wang lab has been developing fetal tissue engineering approaches using different types of stem cells, stem cell-derived extracellular vesicles, and extracellular matrix-mimicking biomaterial scaffolds to engineer the fetal environment and treat a variety of birth defects before birth. One of the major projects his lab has focused on over the past decade is on developing a stem cell technology for the fetal treatment of spina bifida. His team have successfully manufactured clinical-grade placenta-derived mesenchymal stem cells (PMSCs) in the UC Davis GMP facility, acquired IND approval from the FDA, and are currently conducting a first-in-human Phase 1/2a clinical trial for the in utero treatment of spina bifida using PMSCs. The Wang lab is also working on using lipid nanoparticles to deliver mRNAs to genetically modify developing stem cells to treat genetic diseases before birth. To harness the stem cell behavior, novel integrin-based ligands identified via One-Bead One-Compound (OBOC) combinatorial technology have been applied to target stem cells and improve stem cell attachment, migration and function.

Dynamic Control Of Active Matter: Nano Seminar Series, April 12https://events.berkeley.edu/live/events/229975-dynamic-control-of-active-matter-nano-seminar

Through the magic of ‘active matter,’ which converts chemical energy into mechanical work to drive emergent properties, biology solves a myriad of seemingly impossible physical challenges. I will present my lab’s efforts to develop new fluid mechanics models to direct the flow of matter enabled by the use of “active” molecules found within living systems.

We design 2D composite materials with tunable inclusions of lipid domains embedded within an active elastic network. These mechanoresponsive lipid inclusions enable exquisite control over the phase separation and material properties (like failure resistance) of 2D composite materials. I will also present our recent work on model predictive control and learning of many-body colloidal interactions driven by active and hydrodynamic forces.

Bioengineering Seminar: Engineering Extracellular Matrix Viscoelasticity to Probe Cellular Responses, April 17https://events.berkeley.edu/bioe/event/229420-bioengineering-seminar-engineering-extracellular-matr

Abstract:

In the body, cells are surrounded by a scaffolding of biopolymers that provide physical support and biochemical cues, known as the extracellular matrix (ECM). Hydrogel cell culture models have been used to reveal that properties of the ECM, notably matrix stiffness, can regulate a host of cellular behaviors, such as migration, division, differentiation, and even cancer progression. ECM is often viscoelastic, displaying stress relaxation in response to strain, and recapitulating complex aspects of native ECM, such as dynamic remodeling and viscoelasticity, remains challenging. Further, key aspects of mechanotransduction, such as the effect of mechanics on the epigenome, are not well understood. In this talk, I will discuss how matrix stiffness can induce epigenomic remodeling leading to a tumorigenic phenotype in a breast cancer model. I will also describe our work to develop 3D hydrogel platforms that allow for dynamic tuning of matrix viscoelasticity to better understand the biological impact and pathways involved in mechanotransduction.

Printing Functional Polymers for Sustainable Earth and Habitable Mars: Nano Seminar series, April 26https://events.berkeley.edu/live/events/229388-printing-functional-polymers-for-sustainable-earth

Printing technologies have the potential to revolutionize manufacturing of electronic and energy materials by drastically reducing the energy cost and environmental footprint while increasing throughput and agility. For instance, printing organic solar cells can potentially reduce energy payback time from 2-3 years to as short as 1 day! At the same time, additive manufacturing of such functional materials brings a new set of challenges demanding exquisite control over hierarchical structures down to the molecular-scale.

We address this challenge by understanding the evaporative assembly pathway and flow-driven assembly central to all printing processes. We discover a surprising chiral liquid crystal mediated assembly of achiral semiconducting polymers in an evaporating meniscus. We uncover the molecular assembly mechanism and further show that the chiral helical structures can be largely modulated by controlling printing regimes.

Such new topological states of semiconducting polymers can empower unprecedented control over charge, spin, and exciton transport, reminiscent of how Nature efficiently transfers electrons and transduces energy using chiral helical structures. The ability to control non-equilibrium assembly during printing sets the stage for dynamically modulating assembled structures on the fly.

We demonstrate this concept by programming nanoscale morphology and structure color of bottlebrush block copolymers during 3D printing. This approach holds the potential to reduce the use of environmentally toxic pigments by printing structure color. Complementing the above hypothesis-driven approach, we are pursuing data-science driven approach to drastically accelerate discovery and manufacturing of functional polymers. By linking automated synthesis, testing, and machine learning in a close-loop, we are able to optimize function highly efficiently while discovering new physical insights for transferring closed-loop optimization into hypothesis driven discovery.
