Abstract: Carbocations are important reactive intermediates that are invoked in many chemical transformations. These species are usually of the tricoordinated variety. Conversely, dicoordinated carbocations are rarely relevant in practical chemical processes due to their high energy and energetically challenging formation. In this talk I will discuss our recent efforts to utilize phenyl and vinyl carbocations […]

The UCLA Department of Chemistry & Biochemistry invites all incoming first-years and transfer students to our New Undergraduate Student Welcome event on Wednesday, September 30, 2020 from 10:00 a.m.- 11:00 a.m. Students will have the opportunity to hear from faculty and current students on various topics including academics, undergraduate research, and student involvement. There will also […] Abstract: Electrochemical nanomaterial has witnessed its extensive applications in catalysis, energy storage, and conversion. So what are the new frontiers for electrochemistry and nanomaterials? Can we discover new synergies of electrochemical nanomaterials with research disciplines that were not often considered before? Because electrochemical nanomaterials spatiotemporally transform chemical species and control their concentration profiles at a microscopic […] |

1 event,“Heterogenized Molecular Catalyst Materials for Electrochemical Carbon Dioxide Conversion” Abstract: Sustainable energy utilization and carbon emission reduction are critical challenges for the world. Solving these challenges requires precise control of many important chemical reactions with sluggish kinetics and myriad possible reaction pathways and associated products. There is a critical need for selective, active, durable and […] |
2 events,“Implantable and Wearable Bioelectronics: Eavesdropping on Chemical Signaling” Advisors: Prof. Paul Weiss and Prof. Anne Andrews Abstract: The Sletten Group works in three different areas which all encompass “fluoro” to control and detect chemistries in living systems. These include 1) fluorous nanoemulsions as versatile scaffolds for drug delivery, 2) fluoroarenes as chemical reporter groups for non-covalent bioorthogonal chemistry, and 3) fluorophores for the shortwave infrared region of the electromagnetic spectrum for real-time […] |

2 events,The NSF Center for Integrated Catalysis is delighted to announce that it will be hosting a monthly webinar series. The second day of this series will be held on Tuesday, October 20th at 1:00 PM. We are pleased to invite all students, postdocs, faculty, and staff. Zachary Edward Hemminger Wollman Group “Scaling up Spatial Transcriptomics using dredFISH” |
1 event,“An Organometallic Approach to the Assembly of Atomically Precise Nanomaterials” Abstract: There is significant interest in the ability to build atomically precise nanocluster molecules with complex three-dimensional structures resembling the intricate molecular architectures found in natural systems. We have developed a platform to access a class of robust, well-defined, three-dimensional hybrid nanomolecules with high tunability […] |
3 events,“Rewriting the Rules of Heterogeneous Catalysis for Supported Subnanometer Metal Cluster Catalysts” Advisor: Professor Anastassia Alexandrova Abstract: The process development of a BACE-1 inhibitor is described. In order to address major safety and scalability limitations in the Discovery synthesis, two novel reactions were developed. The discovery, development, and scale-up of these reactions will be described. Several additional methodologies which emerged during process research will also be presented. Abstract:The selective introduction of functional groups at the positions of typically unreactive C-H bonds has been a longstanding challenge in catalysis. To this end, our group has developed practical methods for the catalytic functionalization of C-H bonds with main group reagents.(1-4) These studies have led us to a general strategy of installing a single transient […] |

1 event,“Imagining, Building, and Understanding the Next Generation Battery” Abstract: Electrochemical energy conversion and storage is critical for vehicle electrification and storing clean energy from intermittent sources (i.e. wind, solar) on the grid. Towards these goals, my group pursues the broad spectrum of stages necessary for technological innovation: (1) developing new tools to discover fundamental understandings, […] |
1 event,Abstract:The potential to use mechanochemistry, either in isolated polymers or in polymeric materials, to trigger a programmed, desirable covalent molecular response was first revealed only a decade or so ago. Since that time, covalent polymer mechanochemistry has undergone a renaissance in which it has been extensively explored by a number of research groups and for a variety of purposes including (but not limited […] |
