“Toward Single Atom Catalysis for Environmental Application”

Various noble metals have been employed as catalysts and co-catalysts to enhance the kinetics of reactions that are critical for environmental remediation. The need to maximize the available catalytic sites per unit mass, particularly due to noble metal scarcity and high cost, has driven the development of material architectures at the nanometer scale. Recent theoretical and experimental studies have explored noble metal catalysts on the subnanometer, atomic scale to maximize atomic efficiency. A single atom catalyst (SAC), also called atomically dispersed catalyst, is the theoretical limit in this endeavor, and previous studies have identified additional benefits such as low coordination state and strong interaction with the surrounding substrate resulting in enhanced selective catalysis. For past few years, our group has since been exploring various SACs (Pt, Pd, Ag, and Co) anchored on different substrates (SiC, C3N4, and TiO2) that exhibit unique catalytic properties. This talk summarizes our recent studies to advance the water treatment catalysts from the nano-scale toward the single atom scale such as (1) single-atom Pt and Pd anchored to SiC for selective defluorination of perfluorooctanoic acid (PFOA) and selective dehalogenation of various water pollutants and (2) spatial separation of two co-catalysts coordinating single atom cobalt at the void center of C3N4 and anchoring anthraquinone at the edges of C3N4 platelets to significantly enhance the catalytic synthesis of H2O2, a precursor chemical for advanced oxidation.


Dr. Jaehong Kim is currently Henry P. Becton Sr. Professor of Engineering and Department Chair of Chemical and Environmental Engineering in School of Engineering and Applied Science
at Yale University. His areas of interest include: 1) environmental application of nanomaterials;
2) development of photoluminescence / photocatalysis technology for environmental and
energy application; and 3) membrane process and materials development. Kim received B.S.
and M.S. degrees in chemical and biological engineering from Seoul National University in
Korea in 1995 and 1997, respectively, and a Ph.D. degree in environmental engineering from
the University of Illinois at Urbana-Champaign in 2002. After graduation, he joined the School
of Civil and Environmental Engineering at Georgia Institute of Technology where he later held
the title of Georgia Power Distinguished Professor and Associate Chair for Undergraduate
Programs. He then moved to Yale University in 2013 as Barton L. Weller Endowed Professor.
He has taught undergraduate courses such as Water Quality Engineering, Environmental
Technology in the Developing World, and Environmental Engineering Laboratory, and graduate
courses such as Physicochemical Processes and Design of Drinking Water Treatment Facilities.
He is a recipient of various awards including Ackerman Award for Teaching and Mentoring
from Yale University (2017), Bill Shultz Junior Faculty Teaching Award from School of Civil and
Environmental Engineering (2013), Walter L. Huber Civil Engineering Research Prize from
American Society of Civil Engineers (2013), Top Environmental Technology Paper Award from
American Chemical Society (2012), Paul L. Busch Award from Water Environment Research
Foundation (2009), Excellence in Research Award from Georgia Institute of Technology (2009),
and CETL/BP Junior Faculty Teaching Excellence Award from Georgia Institute of Technology

“Toward Securely Connected World”

As the primary element of connected world, IoT promises to transform the way we work, live, and play. As many of these IoT devices are resource constrained in
terms of processing, bandwidth, and storage, equipping security and intelligence
on these devices faces enormous technical challenges. The hacking of IoT devices
and privacy fears already grabbed public attention. If the issue of IoT security is not
resolved in a timely manner, the envisioned connected world built on IoT, may be
a story in the distant future. This talk discusses the information technology
evolution toward IoT in the view of entropy expansion. Future trends of IoT
technologies will be explored in the core areas of IoT including security and
machine learning. Discussion also extends to an effective approach installing an
intrusion detection system inside an IoT device itself.


Dr. Myung Jong Lee received a B.S and MS from Seoul National University and Ph.D from Columbia University in electrical/electronics engineering. He is currently a professor at the Dept of Electrical & Computer Engineering, City College, and Computer Science Graduate Center, City University of New York. He is also an adjunct professor at GIST. He was a visiting professor to Bellcore, Seoul National University, and Samsung Advanced Institute of Technology. Dr. Lee’s recent research interests include wireless communication networks, 5G testbed, secure IoT, mobile cloud computing, V2X, and stochastic computing applications. His researches have been funded government agencies and leading industries, including, NSF, US Army, AT&T, Panasonic, Samsung and ETRI. He authored and coauthored over 200 international journal & conference papers, a book more than 25 U.S and international patents. Dr. Lee also actively contributed to international standard organizations IEEE and ZigBee (TG chairs for IEEE 802 15.5 &15.8).  Dr. Lee’s research group developed the first NS-2 simulator for IEEE 802.15.4, a standard NS-2 distribution widely used for wireless sensor network researches. He received the best paper awards (IEEE CCNC 2005, INCos2019, EAI 2016) and CUNY Excellence Performance Award. Dr. Lee founded the Secutopia Corp developing hardware security solution for IoT devices using stochastic machine learning while serving the first president of KITEE. He served the KSEA in various capacities including NY metro Chapter president, 42nd HQ President, Chair/program chair ofNRC.
