Title: Deciphering the mechanisms of surface photoinduced and photocatalytic reactions using femtosecond UV and XUV laser pulsesAbstract:The detection of highly unstable intermediate species during surface photoinduced and photocatalytic reactions and the correlation of their dynamics with the surface properties is crucial to fully understand and control heterogeneous reactions. In this work, an experimental methodology that combines surface mass spectrometry with a femtosecond pump-probe technique and ultraviolet multiphoton or extreme ultraviolet single photon ionization is employed to decipher the mechanisms of surface photoinduced and photocatalytic reactions. The technique relies on the detection of highly unstable intermediate species and final products with time-, mass-, and energy resolution.In the first part of the talk, the photoinduced reaction dynamics of methyl iodide adsorbed on an amorphous cerium oxide ultrathin film is investigated to understand the effect of random molecular adsorption geometries on the surface reaction. In the second part of the talk, an experiment is presented in which the ultrafast photodissociation dynamics of CH3Br molecules adsorbed on variable size Au clusters on MgO/Mo(100) is investigated by monitoring the CH3+ transient evolution. Extreme-ultraviolet photoemission spectroscopy in combination with theoretical calculations are employed to study the electronic structure of the Au cluster on MgO/Mo(100). Changes in the ultrafast dynamics of CH3+ fragment are correlated with the electronic structure of Au as it evolves from monomers to small nonmetallic clusters to larger nanoparticles with a metallic character.In the last part to the talk, an experiment will be presented in which the photoinduced reaction of D2O in the presence of CH3I is monitored on an n-type (Nb) doped TiO2(100) surface. In this experiment intermediate species such as D, OD, and DO2 are detected when only water is dosed on the TiO2 (100) surface. When both D2O and CH3I are dosed on the surface, besides the intermediate species mention above, CH3 and I radicals as well as methane (CH3D) and methanol (CH3OD) are observed. Details about the surface properties and how this affects the surface chemical reactions will be provided.About the Speaker: Dr. Mihai E. Vaida is an associate professor in the Department of Physics and a member of the Renewable Energy and Chemical Transformation Cluster at the University of Central Florida (UCF). His research, which combines surface science and ultrafast spectroscopy, focuses on understanding the properties of catalytic and photocatalytic materials as well as surface reaction mechanisms. Prior to joining UCF, he earned a doctoral degree in physical chemistry from the University of Ulm, Germany and was a Postdoctoral Research Fellow at the University of California, Berkeley. He received several awards including NSF Career award, UCF Research Incentive Award, UCF COS Excellence in Research Award, DAAD Scholarship (German Academic Exchange Program), Erasmus and Erasmus Plus Scholarships, and EMSPS (European Mobility Scheme for Physics Students) Scholarship.Virtual Location URL: https://ucf.zoom.us/j/91965880588?from=addon

This special lecture is presented by Keith Knapp, professor of history in The Citadel at the The Military College of South Carolina.This is part of the Reaching for the Stars as a Global Citizen: An Intellectual Journey of Asia and the World lecture series. This lecture series provides a rare opportunity for students to learn first-hand from esteemed scholars about one of the most important regions in the world today. Students from UCF's top-ranking schools and programs will develop a more comprehensive understanding on the cultural, political and economic forces that have shaped modern Asia through this Special Lecture Series. Asia has a major role in manufacturing, technology and investment markets. Non-governmental organizations specializing in economic development, healthcare and environmental protection also are active throughout Asia. The goal of this course is to help students become global citizens who look forward to the prospects of cooperation between Americans and Asians in building a better, conflict-free world in the 21st century.

Federal, state and local government procurement is the largest target market in the world.The question is usually not "Does the government buy what you are selling?" It is more, "Can you be competitive enough and relentless enough to position your business to win government contracts?" If you think you can be competitive, then government contracting may be a good growth opportunity for your business.The Government Contracting Overview seminar, presented by the APEX Accelerators at UCF in partnership with the Florida SBDC at UCF, is designed for established small business owners with some commercial momentum that are curious about government contracting, as well as business owners that may already be involved in government contracting. This workshop will present government contracting in three components: positioning for government contracting, developing reactive business development strategies and developing proactive business development strategies. Specifically, we will discuss registration requirements, social-economic certification opportunities, market research tools, Florida PTAC's "Bid-Match" system and what we refer to as the initial "marketing tool kit" for government contractors.Join us for this great learning opportunity!Virtual Location URL: https://events.blackthorn.io/en/6g3Q8Wa7/government-contracting-overview-5a1e6g4Tumq/overview Registration Link: https://events.blackthorn.io/en/6g3Q8Wa7/government-contracting-overview-5a1e6g4Trwr/overview

Join Dr. Amit Baishya from the University of Oklahoma as she speaks about new critical studies on South Asian Horror and Anthropocene in her talk: Indian National Weird: The Aesthetics of Air as Horror in New Literary Narratives.This talk considers new theoretical categories in the "aesthetics of the weird" and their double valence of the terns, "atmosphere" and "weird" in emerging South Asian literature. I will be focusing on the aesthetics of the weird, a post-Lovecraftian generic descriptor that merges horror, science-fiction and speculation, to depict the vicissitudes of the Anthropocene emerging literary narratives such as Siddhartha Deb's new work The Light at the End of the World. In the era of Anthropocene, the "atmosphere" has become "weird" and in a different sense as a novel on the Anthropocene, the atmosphere that the characters inhabit is literally weird because of anthropogenic impacts such as air pollution. This latter aspect is especially germane in the representation of New Delhi, which is routinely listed as a city with poor air quality. In this talk, I focus exclusively on the Delhi segments of this sprawling heterotemporal and multiscalar novel. Zooming in especially on atmospheric pollution and it's differentiated impacts on the city's populations, the creation of insulated and exclusionary "bubbles" (Peter Slotedijk) through technologies like air conditioning, and the mediated representation of air through techno-visualizations like the Air Quality Index (AQI), my talk traces the double valence of weird atmospheres, and argues that the 'weird' may be one of the most powerful generic modes to depict how elemental substances like air are changed, changed utterly in the epoch of the Anthropocene.CHDR Presents is an ongoing talk series hosted by the Center for Humanities and Digital Research (CHDR) where scholars share innovative, award-winning, creative research to both showcase their work and foster collaboration.This event is supported by the UCF India Center and the Department of English.
