Simulating Energy Transfer and Storage in the Condensed Phase: From Photosynthesis to Batteries

I will discuss recent advances in modeling coupled electronic and vibrational dynamics that govern energy flow in condensed-phase systems. I will first present all-state quantum dynamics simulations of excitation energy transfer in the bacterial light-harvesting complex (LH2), showing how its ~90% efficiency and ~1 ps timescale arise from its concentric pigment architecture and nuclear quantum effects.

Nucleophilic Cobalt Photocatalysis and Organic Photoreductants: Two Enabling Approaches to Organic Synthesis

While carbon-centered radicals have become an increasingly important tool in organic synthesis, the breadth of radical precursors available to synthetic chemists remains underdeveloped. Many of the radical precursors employed in these methods require pre-functionalization of the initial feedstock chemical, adding undesired synthetic steps while generating additional byproducts after radical formation.

Two Hundred Years after Hamilton: Exploring New Formulations of Classical and Quantum Mechanics

Abstract: This talk has three parts. The first part is an introduction to Hamilton’s two monumental papers from 1834-1835, which introduced the Hamilton-Jacobi equation, Hamilton’s equations of motion and the principle of least action [1]. These three formulations of classical mechanics became the three forerunners of quantum mechanics; but ironically none of them is what Hamilton was looking for -- he was looking for a “magical” function, the principal function S from which the entire trajectory history can be obtained just by differentiation (no integration) [2].

Discriminating Polymer Microstructures through Nanoporous Crystals

Biography: Nobuhiko Hosono received his Ph.D. in polymer chemistry at the University of Tokyo in 2011. From 2011 to 2013, he worked at Eindhoven University of Technology as a research fellow of the Japan Society for the Promotion of Science (JSPS). In 2014, he was promoted to Assistant Professor of the Institute for Integrated Cell-Material Sciences (iCeMS), Kyoto University. In 2018, he was appointed Lecturer at The University of Tokyo. In 2021, he was appointed to Associate Professor of Graduate School of Engineering, the University of Tokyo.

From Neural Interfaces to Computing Paradigms

Abstract: Interest in Artificial Neural Networks (ANNs) has surged in recent years due to their remarkable versatility in addressing a wide range of complex problems. Today, ANNs are predominantly implemented on electronic platforms. While very-large-scale ANN models have been developed that surpass human performance in specific tasks, they do so at the cost of long training times and significant power consumption.

The Editor’s Role in Publishing at Chem and Some Advice for Scientific Writing

Abstract: Ever wondered what goes on behind the scenes when you submit a manuscript to a journal? Dr. Gillian Hatzis, a Scientific Editor at Chem, will discuss publishing at Cell Press, her editorial process for handling submitted works, give some advice on how to write more effectively for any audience, and share how she began her career as an editor.
