“New Approaches to Mesenchymal Stem Cell Therapy”

Recently there has been a paradigm shift in what is considered to be the therapeutic promise of mesenchymal stem cells (MSCs) in diseases of vital organs.  Originally, research focused on MSCs as a source of regenerative cells through the differentiation of transplanted cells into lost cell types.  It is now clear that trophic modulation of inflammation, cell death, fibrosis, and tissue repair are primary mechanisms of MSC therapy.  This has been clarified in studies where delivery of growth factors, cytokines, and other signaling molecules secreted by MSCs is often sufficient to obtain the therapeutic effects.  In this presentation, examples of MSC therapy in disease models of vital organs using models of acute liver failure, acute renal injury, and spinal cord injury will be described.

Industry Engagement 101: Collaborating with Commercial Enterprises (Workshop)

March 9 @ 11:00 am1:00 pm

Many factors are driving an increase in engagement between universities and industry; including increased competition for redirected and/or declining governmental research investments and the creation of products and markets that require a workforce with new skills. As University researchers navigate these dynamics it is important to understand the extent to which successful relationships are dependent on an understanding of corporate decision making, the ability to manage expectations, and taking a holistic approach to finding win-win value propositions on the industry/university engagement continuum. Strategic partnerships in this domain merge the discovery-driven culture of the university with the innovation-driven environment of the company. But to make the chemistry work, each side must overcome the cultural and communications differences that often impair industry/university partnerships of all types and undercut their potential. This workshop, led by staff from the Industry Liaison Office, addresses the challenge of bridging the industry-university divide by providing researchers with a fundamental understanding of the value of industry engagement and the engagement continuum, tools for rapidly vetting and solidifying industrial opportunities, and knowledge of the support resources at OSU that are key to helping secure and nurture industrial relationships.

Who: OSU faculty, staff, and postdocs
When: Thursday, March 9, 11:00 a.m. – 1:00 p.m.

Please join us for a CME Seminar presented by Professor Wei Han from ICQM, Peking University, China as he shares his research on “Spin and Charge Conversion in 2D Quantum Materials”.

Abstract

Spintronics aims to use the spin degrees of freedom for future information technologies. A key challenge for spintronics is the efficient generation of spin currents from charge currents. Recently, emergent 2D quantum materials are very attractive for spintronics since they provide new mechanisms of spin currents generation [1].
In this talk, I will present the spin and charge conversion in three quantum materials. The first part of my talk will discuss the facet-dependent spin Hall effect and spin orbit torque in single crystalline antiferromagnetic IrMn3 [2], This result suggests a novel mechanism of the spin current generation arising from the triangular spin configurations in the single crystalline IrMn3. The second part of my talk will discuss the spin to charge conversion in the spin-momentum locked surface states of the topological Kondo insulator (SmB6), of which pure surface states exist at low temperatures [3]. At the end, I will present on the gate tunable charge to spin conversion at room temperature using the Rashba-split 2DEG at the complex oxides (SrTiO3 and LaAlO3) interface [4].

The Edward Mack, Jr. Lectures

Professor Edward Mack, Jr. was a long time faculty member of the Chemistry Department at The Ohio State University. After fourteen years as chairman, he resigned in October, 1955, to be devoted full time to teaching and research. Not long thereafter his friends and former students learned of his death in June, 1956.

Professor Mack’s research interests included the determina- tion of the sizes and shapes of molecules from collision cross-sections using kinetic gas measurements. He also studied the rates and mechanisms of gas phase reactions, surface films, and biochemical problems. Professor Mack is remembered as a man of great energy and enthusiasm for research as well as his students.

Professor Mack became a member of the faculty at Ohio State in 1919 when he immediately began to take a personal interest in graduate students. He was their continual advocate, aiding his students through difficult years by soliciting grants from many companies and businesses. In many cases, he even took funds out of his own pocket for their support. Professor Mack was entirely dedicated to his graduate students, both scientifically and personally. In this spirit, the graduate students are responsible for every aspect of the Mack Memorial Award.

Graduate Students participate in the Mack Memorial Award by serving on the Mack Award’s committee, nominating individuals, voting for the Mack Award recipient, and, of course, for attending the talks and joining the celebration.

Seminar: Vibration Analysis of Spinning Rotors with Flexible Bearings and Housing Supports

Rotary machines appear everywhere in our daily life ranging from jet engines to computer hard disk drives.  Every rotary machine consists of three basic elements: a rotary part (rotor), a stationary part (housing), and multiple bearings that connect the rotary and stationary parts.  The rotor can be axisymmetric (e.g., hard disk drives) or cyclic symmetric (e.g., wind turbines).

In this presentation, we will discuss how bearings and housing affect vibration of a spinning rotor.  Mathematical models are developed through use of Lagrange equation, finite element analyses and component mode synthesis.  The mathematical modeling leads to the following conclusions.  First, when a rotor is assembled to housing via bearings, some vibration modes will not change their natural frequencies and mode shapes. These modes have the characteristics of zero inertia force and inertia moment.  Therefore, they are called “balanced modes.”  Otherwise, a vibration mode is called an “unbalanced mode.”  Only unbalanced modes will be coupled to the housing and bearings.  Second, for axisymmetric rotors, unbalanced modes will appear in the form of precession or axial translation when they are coupled with the housing and bearings.  In the case of hard disk drives, one-nodal-diameter disk modes present precession and axisymmetric disk mode present axial translation. Disk modes with 2 or more nodal diameters are balanced modes.  Third, for cyclic symmetric rotors, balanced or unbalanced modes will depend on the number of repeated substructures  and a “phase index” , which determines the phase angle between two neighboring substructures.  A vibration mode is a balanced mode if , , or .  Finally, when mistuning is present in a cyclic symmetric rotor, localized vibration modes may appear.  Presence of bearings may introduce more localized modes and may couple the housing to the rotor. Localized modes are unbalanced with larger bearing forces.

Majority of the mathematical predictions have been validated via calibrated experiments.

Neutrino Astronomy Made Easy

Neutrinos barely exist: They have almost no mass or interactions.  Yet they are blazing forth from the hot, dense centers of nuclear reactors, the Sun, supernova explosions and who knows what else?  If only we could see them!  With new detectors, now we can, but faintly, opening up new vistas, questions and possibilities.

John Beacom is Ohio State professor of physics and astronomy; director, Center for Cosmology and Astroparticle Physics (CCAPP); and frequent public speaker and contributor to online publications.
