“f-Block metal-arene interactions: from inverse sandwiches to redox chemistry” Abstract: Recent years have witnessed the breakthrough of identifying unusual oxidation states of f-block elements in molecular compounds such as divalent rare earth metals and actinides, as well as tetravalent terbium and praseodymium. By taking advantage of the symmetry and energy match between the f/d orbitals […]

“Earth-Abundant Molecular Catalyst System for the Reduction of Dioxygen and Carbon Dioxide” Abstract: The steady increase in anthropogenic carbon dioxide (CO2) emissions and corresponding atmospheric concentrations continues to generate interest in using CO2 as a liquid fuel and commodity chemical precursor. The conversion of CO2 has the dual benefit of addressing its associated negative environmental […]
"Scanning probe microscopy for physical and chemical property characterizations at the nanoscale"
The NSF Center for Integrated Catalysis is delighted to announce that it will be hosting a monthly webinar series. The next webinar of this series will be held on Tuesday, April 13th, 2021 at 1:00 PM. We are pleased to invite all students, postdocs, faculty, and staff.
Abstract: Perfluorocarbon nanoemulsions, droplets of fluorous solvent stabilized by a polymeric amphiphile dispersed in water, are an intriguing platform for drug delivery. The fluorous phase is biocompatible, has a high dissolved oxygen content, and is both lipophobic and hydrophobic, preventing the leaching of payloads. Here, we describe the use of perfluorocarbon nanoemulsions as a drug […]
The UCLA Molecular Biology Institute (MBI) will hold the 2020-2021 Sigman Symposium in honor of Professor David Sigman (1939-2001), who was an internationally renowned UCLA professor of chemistry and biological chemistry who illuminated the molecular mechanisms by which enzymes catalyze biological reactions and was one of the founding members of the MBI. 2020-2021 Sigman Award Honoree: […]
Abstract: This lecture will describe some recent developments in the area of electrophotocatalysis, with a particular focus on a trisaminocyclopropenium (TAC) ion catalyst developed by our group.
Quinlan Group "Biochemical Characterization of Mammalian Formin FHOD3 in Cardiomyocytes”
Abstract: Biopharmaceutics are widely used to treat serious diseases, but the architectural and chemical complexity that makes proteins good therapeutics renders them susceptible to degradation and aggregation during manufacturing, transportation, and storage. Loss of intact biopharmaceutics causes patient under-dosing as well as adverse reactions. With the growth of biopharmaceuticals coming to market, the need increases […]
“Synthetic Nanorobot – from Individual Microswimmer to Active Swarm” Abstract: Over 60 years ago, Prof. Richard Feynman envisioned that, in principle, machines could be made so tiny, we can use them to construct matters from atomic/molecular scale; nanorobots can perform surgeries and deliver drugs at cellar level. Sixty years later, the scientific community finds an […]
“Superparamagnetic Core/Shell Mesoporous Silica Nanoparticle for Magnetic Heating-Induced Anticancer Drug Delivery” ABSTRACT: Superparamagnetic iron oxide nanoparticles (SPION) generate heat in the presence of an alternating magnetic field (AMF) and are used in clinics to treat cancers. Mesoporous silica nanoparticles (SPION@MSN) embedded with SPION possess the advantageous features of both the SPION core and the shell, […]
Abstract: N4-acetylcytidine is an ancient RNA modification catalyzed by an enzyme essential for human life. However, its distribution, dynamics, and function remain mysterious. In this seminar I will introduce my group’s work developing chemical tools to investigate RNA acetylation, why this led us to study an organism that thrives in solfatara (volcanic craters), and how […]

Abstract: The NIH Molecular Libraries Program was founded to translate the discoveries of the Human Genome Project into therapeutics through a network of high-throughput screening (HTS) centers. A decade of discovery produced hundreds of probes—highly selective small molecules that modulate cellular function—but centralized HTS bears the same cost and infrastructure burdens of millennial DNA sequencing […]
“Enhanced Gas Transport in Hybrid Bio-Inorganic CO2 and N2 Fixation Systems” Abstract: With the surge of intermittent, renewable electricity, the storage of excessive electricity and reduction of CO2 or N2 into value-added chemicals is of great significance for a sustainable society. One viable route is to construct a hybrid inorganic-biological system that converts electricity into […]
“Van der Waals Integration beyond 2D Heterostructures” Abstract: The integration of dissimilar materials to form heterostructures with designable electronic interfaces is central in modern electronic devices and has thus been a long pursuit in material science. The traditional integration methods such as metal evaporation, atomic layer deposition (ALD) and epitaxial growth typically rely on strong […]
Abstract: Development of new synthetic strategies via organic photocatalysis in our group was described. Both photoacidic activity and photoredox activity of organic photocatalysts were discussed. A series of phenol-conjugated acridinium-based organic photoacids were rationally designed, synthesized and studied alongside commercially available phenolic catalyst, eosin Y. In the presence these photoacid catalysts and light, synthetic glycals […]
