Can Aygen

Resistivity and Stress Relaxation Studies on Electrically Conducting Rubber Composites

Department of Electrical and Computer Engineering, Northwestern University

Host Professor: Noa Lachman

Can Aygen is one of three NU-TAU Nanoscience & Nanotechnology Fellows participating in a joint project developing a touchpad-based resistance tomography system between the Grayson lab at Northwestern, spearheading the electrical measurement aspects of the project, and the Lachman lab at Tel Aviv, which handles materials and fabrication.  Aygen’s research focuses on heavy tail relaxation behavior in disordered systems, for which he has developed an analysis software package.  His work at TAU will focus on testing the reliability of this software under a larger range of conditions, while adapting it for work on impedance measurement of the composite materials the larger project is developing.  With the rapid, real-time snapshots this work will provide, the research team can gain multiple data points for each millisecond-long event being measured.

 

Dr. Yu Chen

Endogenous peptide-driven biomimetic mineralization for controlled intracellular drug delivery

Center for Nanoscience and Nanotechnology, Tel Aviv University

Host Professor: Nathan Gianneschi

 Dr. Yu Chen's research is focused on developing self-assembling peptide structures with helpful medicinal properties. Chen's current research focuses on researching minimalistic peptide building blocks that, when combined with metal ion, can be used to create structures capable of collecting medicines and releasing them slowly into a patient.  This solution would allow researchers and doctors to monitor and manipulate drug delivery using materials that are common in the body, and can be easily tolerated and broken down when no longer required.  Dr. Chen’s research aligns with the Gianneschi lab’s own expertise in peptide-polymer structures, and will benefit from the advanced real-time imaging technology available there for more precise monitoring of the peptide assembly process.

 

Yoav Dan

A Correlative Light-Electron Liquid-Phase Microscopy for Elucidating Mechanism, Dynamics, and Assembly of Dipeptides

Department of Oral Biology, Tel Aviv University

Host Professor: Nathan Gianneschi

Yoav Dan’s research focuses on the formation process and properties of Tert-Butoxycarbonyl-FF (Boc-FF) crystals.  Building on previous work at the Adler-Abramovich laboratory investigating differences in monoclinic and orthorhombic crystal composition, Dan will make use of  liquid cell transmission electron microscopy methodologies developed in the Gianneschi laboratory for real-time, high resolution imaging.  These images, supplemented with simultaneous bulk scale microfluidic platform experiments promise new insights into the processes under which Boc-FF crystals form and interact.  Dan’s work at Northwestern will deepen an existing research partnership between the Adler-Abramovich and Gianneschi groups.

 

Dr. Pranab Mohapatra

Controlling Nucleation Density of 2D Materials: From Nanodomains to Large Single Crystals for Advanced Electronics and Optoelectronics

Department of Materials Science and Engineering, Tel Aviv University

Host Professor: Mark Hersam

 Dr. Pranab Mohapatra’s research focuses on the production of transition metal dichalcogenides (TMDC), crystal films used as nanoscale semiconductors.  Dr. Mohapatra has worked extensively in developing metal organic chemical vapor deposition (MOCVD) techniques for improving material quality and purity in large scale production, including a novel Growth-Etch process for increased optical quality.  He will be joining Dr. Hersam’s lab for a joint further investigation of TMDC growth for electronic and optoelectronic applications, particularly the effects of domain size and defect density on the properties of the films produced.  The Primary Investigator of Dr. Mohapatra’s laboratory at Tel Aviv University, Professor Ariel Ismach, will be accompanying him for the duration of the fellowship, allowing for an uncommonly deep collaboration between the two research groups.

 

Claire Onsager

Studying Membrane Strain and Conductivity for Resistive Tomography Applications

Department of Electrical and Computer Engineering, Northwestern University

Host Professor: Noa Lachman

Claire Onsager is a member of the joint Grayson-Lachman project developing the touchpads for resistance tomography imaging.  This project has resulted in the parallel design and construction of stress-relaxation measurement systems in both labs based on shared blueprints, with the Tel Aviv device designed for rapid measurement and the device at Northwestern designed for longer-term observation.  As part of this project, built the physical components of the Northwestern device, and has been developing a rapid-refresh 2D tomographic algorithm to map localized stress in the material.  During the exchange program, Onsager will collect large amounts of data from the Tel Aviv device, compare methodologies with the Lachman lab team, and continue the process of testing and refining the materials and measurement methods of the larger project.

 

Parul Rathee

RAFT and ROMP based enzyme responsive amphiphiles as building blocks for smart polymeric nanocarriers

Department of Chemistry, Tel Aviv University

Host Professor: Nathan Gianneschi

 Parul Rathee studies enzyme-responsive polymers that can be used for targeted drug delivery, and will be joining the Gianneschi lab to gain experience with RAFT and ROMP polymerization processes.  These methods will complement her work in synthetic dendron production in the Amir laboratory at TAU, allowing for the study of new enzyme-responsive polymers.  As part of this process, Rathee plans to utilize the Gianneschi laboratory’s liquid-phase transmission electron microscopy for real-time characterization of polymeric assemblies in their native swollen state.

 

Lev Rovinsky

Dielectric Relaxation Behavior of VMQ/CNT Self-Sensing Stretchable Electrodes

Department of Materials Science and Engineering, Tel Aviv University

Host Professor: Matthew Grayson

 Lev Rovinsky is the third member of the Grayson-Lachman project developing touchpads for resistance tomography to participate in this year’s exchange program.  The project began with the creation of two measuring devices from shared blueprints incorporating the respective expertise of the research labs involved in their creation.  While collaboration has been fruitful so far, Rovinsky’s work at Northwestern will further bridge the difficulties inherent to specialized research teams working on different continents.  Rovinsky will learn electrical characterization techniques that the Northwestern team has been using for measurements, while improving the Northwestern device’s user interface and providing on-site expertise in materials function.  Rovinsky also plans to make use of NUANCE’s specialized microscopy equipment for molecular level research of the relaxation behavior of advanced rubber composites, meant to advance both the larger project and his own research.
