Vilas Pol

“The Quest for Safer Rechargeable Batteries”

Vilas Pol, Associate Professor of Chemical Engineering

The ViPER (Vilas Pol Energy Research) laboratory focuses on the development of high-capacity electrode materials, their engineering for longer cycle life and improved safety. Considering the advantages and limitations of known synthesis techniques, a solventless, single-step processing technology has been developed to fabricate a variety of unique anode and cathode materials for Li-ion, Na-ion, K-ion and Li-S batteries.

Dr. Pol’s talk also will discuss how tailored spherical, solid, dense carbon-particle anodes could make Li-ion batteries safer by distributing current uniformly during charging, minimizing excess solid-electrolyte interphase (SEI) formation and dendritic growth. He also will demonstrate ViPER’s recent efforts on structural, morphological, compositional and electrochemical properties of various fascinating electro-chemistries. Additionally, he will discuss ViPER’s determinations on the transformative science, engineering and technology.

Hong Wan

“Blockchain Basics: Myths and Opportunities”

Hong Wan, Associate Professor of Industrial Engineering

A blockchain is a distributed database that maintains a dynamic list of records, secured against tampering and revision. The main hypothesis is that the blockchain establishes a system that creates distributed consensus in the digital online world. This provides a guarantee to participating entities that a digital event actually happened by creating an incorruptible record in a public ledger. It opens the door for developing an open and scalable digital economy from a centralized one.

Blockchain has caught most its attention from cryptocurrency — encrypted media for financial transactions. However, the technology goes far beyond this specific application. In her talk, Dr. Wan will give a brief introduction of the blockchain, how people misunderstand it, and the potential applications of the blockchain technology. She also will discuss the efforts in her lab to study and design blockchain systems. There will be time for questions and discussions.

David Whittinghill

“Virtual Reality’s Simulator Sickness Problem: Where We Are Today”

David Whittinghill, Associate Professor of Computer Graphics Technology and Computer and Information Technology

Simulator sickness is a phenomenon experienced in virtual reality applications that causes users to experience an intense sensation of vertigo and, in extreme cases, nausea. The simulator sickness problem is multidimensional and complex, having roots in technology, psychology and physiology. At present, a reliable, inexpensive and nonintrusive treatment has yet to be found. Despite the combined efforts of not only the research community but several of the largest technology companies in the world — who have a strong market incentive to be the first to market with a solution — a solution remains elusive.

In this talk, Dr. Whittinghill will discuss the science of simulator sickness in depth to help shed light on this stubborn usability problem. He will summarize and evaluate existing attempts to address the issue, as well as his own research, according to their respective strengths and weaknesses.
