Speaker Abstracts & Bios

"How Particle Structure Provides Performance", Dr. Toivo Kodas & Dr. Bjoern Schimmoeller, Cabot Corporation

Abstract:
This presentation will showcase different performance materials Cabot makes for specific applications. Particles include carbon black for reinforcement applications (e.g. tires), fumed silica as a rheology agent (e.g. silicones), mixed metal oxides as taggants (e.g. security materials), activated carbon as an absorber (e.g. purification) and tantalum particles (e.g. capacitors). Cabot uses classic analysis tools like surface area measurement by nitrogen absorption, crystal composition by x-ray diffraction as well as scanning and transmission microscopy to determine powder and particle structure and properties. The presentation will focus on how particle structure, morphology and composition can influence the final performance in the application.

Toivo Kodas Bio
Toivo leads Cabot's Particle Competency and Front End of Scouting. He is interested in hearing about any new particle technologies and particle applications/markets associated with small and large companies, universities, Cabot and elsewhere. He has a PhD from the UCLA and was a co-founder of Superior Micropowders. Previously he was a professor at the University of New Mexico.

Bjoern Schimmoeller Bio
Bjoern Schimmoeller received his diploma in Process Engineering from University of Karlsruhe (TH) in 2005. He then joined the Particle Technology Laboratory at ETH Zürich for his Ph.D thesis with focus on “Structure of Flame-Made Mixed-Metal Oxide Catalysts”. He received his Ph.D in 2010 and joined Cabot Corporation in 2011 in the R&D department as process engineer. His research interests lie in flame synthesis of (mixed) metal-oxides, metal and ceramic nanoparticles focusing on control of material properties and their performance as well as scale-up studies. During the last 9 years Bjoern has come across quite a few fascinating microscopy images of particles and is happy to share his experiences.

"Polarized fluorescence microscopy for analysis of cytoskeletal architecture" Dr. Shalin Mehta, Marine Biological Laboratory

Abstract:
Polarization is the property of light that carries information about
molecular order in specimens with which the light has interacted. But, polarization cannot be perceived by conventional detectors (human eye or electronic cameras). Most of the fluorescent dyes are well-approximated as dipoles (imagine a nanoscale antenna), whose orientation can be measured by imaging them with polarized light. Polarized fluorescence provides a unique and powerful probe for analyzing position and orientation of ordered cellular assemblies, such as cytoskeleton and membrane, by labeling them with rotationally-constrained fluorescent dyes. Ordered arrangement of constituent molecules underpins the biophysical properties of cytoskeleton and membrane, and therefore, needs to be measured to fully understand their function.

After a brief tour of polarized light microscopy methods developed at Marine Biological Laboratory over several decades, I will discuss new developments in polarized fluorescence microscopy, their computational analysis, and their application to analysis of cytoskeletal architecture at scales ranging from single molecule to whole cells.

Bio: 
I am interested in design of computational microscopy methods to address the measurement challenges posed by cell biology and materials science. I am currently an HFSP (Human Frontier Science Program) Cross-Disciplinary Fellow in the laboratories of Rudolf Oldenbourg and Tomomi Tani at Cellular Dynamics Program of Marine Biological Laboratory. I pursued PhD research in optical phase microscopy at National University of Singapore with Colin Sheppard. I have been fascinated by a variety of signals over the course of my career, such as digital communication waveforms, radar waveforms, human speech, and, presently, intriguing biological processes measured using the microscope and genetic/biochemical techniques.
