Speech Topic: Probing Neural Science at the Micro and Nano Scales
Abstract: According to the United Nations, there is one in every 6 persons in the world suffering from neurologic disorder. In the United States alone, there were 6.2 million patients living with Alzheimer’s disease in 2020; for example. This figure is projected to increase to 14 million in less than 30 years. Between 2000 and 2017, death from heart disease had gone down by 9%, while death from Alzheimer’s disease had gone up by 145%, killing more seniors than breast cancer and prostate cancer combined. At the same time, various treatments for Alzheimer’s disease have not been effective without any known cure. Twenty years have passed between the previous FDA-approved drug for Alzheimer’s disease and the latest accelerated approval of aducanumab on June 7, 2021. One of the main bottlenecks in developing effective and long-lasting treatments in neurological disorders is our yet insufficient understanding of the nervous system and how various disorders impact its physiology. The advent of micro technology is offering tools to probe at the brain at a scale that has never been reached before and provide meaningful augmentation to our current knowledge on how the brain and the rest of the nervous system work. The uses of Microelectromechanical Systems (MEMS) and nanotechnology both in vivo and in vitro have elucidated the intricate and complex network of neuronal tissues and subregions of different parts of the brain. One example of such advances is the reconstruction of hippocampal subregions in a microfluidic device to study the electrophysiology of neural communications. The hippocampus has been known as the center for memory formation, consolidation, and retrieval. The rich axonal spike dynamics between subregions of the hippocampus reveal both constraints and broad emergent dynamics of hippocampal architecture. In particular, certain aspects of how memories are received, sorted, stored, and retrieved can be probed at with analyzing spikes and spike dynamics from subregions of the hippocampus. Further studies could shed light on how the brain learns and unlearns. Similar studies on the other parts of the brain are vital to understanding how disease states impact the brain and how potential therapeutic strategies can be developed meaningfully.

Speech Topic: Analysis of engineering application requirements of nano coating materials in typical atmospheric environment of South China Sea
Abstract: Coatings are the primary means to control the corrosion of marine engineering structures. It is the frontier and hot spot of nano coating materials research to use nano materials to modify anti-corrosion coatings, realize the complementary advantages between different materials, and prepare high-performance, environmental protection, energy saving and functional anti-corrosion coatings. However, with the application of nano coating materials in the atmospheric environment of the South China Sea, there are many problems of poor weatherability. Based on the environmental corrosion characteristics of the South China Sea coastal zone, this paper evaluates the environmental adaptability of several nano coating materials in the coastal atmospheric environment, analyzes the engineering application requirements of nano coating materials, and puts forward the measures and suggestions for the development of nano coating materials in marine engineering in view of the main problems existing in the engineering application of nano coating materials in China.

Speech Topic: Interface Engineering in Heterostructured Metal Selenides for Enhanced Sodium Storage Properties
Abstract: As a promising alternative to the lithium-ion batteries especially in the large-scale applications, sodium-ion batteries possess the distinct advantages including the high reserves of sodium resources. However, the large atomic size of sodium ions causes the sluggish kinetic process as well as severe structural variation during charge/discharge process. To address these problems, we developed effective approaches to construct metal selenides with unique heterostructures, giving rise to interfaces with greatly enhanced electronic and ionic conduction. This led to selenide nanocomposites with significantly improved cycling stability and high-rate performance for sodium-ion batteries.

Speech Topic: Efficient Sn-based Perovskite Solar Cells
Abstract: Tandem solar cells using all metal-halide perovskite thin films show great promise for next-generation solar cells in terms of reduced cost, flexibility, and high efficiency, an effective way to break the Shockley-Queisser limit of single-junction cells. Low-bandgap mixed tin (Sn)-lead (Pb) perovskite solar cells, as a key to make highly efficient all-perovskite tandem solar cells, have been gaining extensive interest due to their appropriate bandgaps and promising application to build efficient all-perovskite tandem cells. Tin fluoride (SnF2) as a basis along with various strategies has been widely used. However, fully understanding the roles of SnF2 in both films and devices is still lacking. Here, we will present the progress and strategies on low-bandgap Sn-Pb cells devoted by our group in the past years. More importantly, we systematically investigate the effect of single SnF2 additive on both optoelectronic properties of low-bandgap mixed Sn-Pb perovskite films and solar cells performance. We find that a decent amount of SnF2 not only suppresses the oxidation of Sn2+ and reduces the hole concentration related to Sn vacancies, but also promotes the perovskite growth, which reduces the disorder of crystal arrangement and improves the crystallinity. We also probe and evidence the location of excessive the F- ions. Our work suggests that such a fundamental understanding of SnF2 additives would definitely help unveil the in-depth mechanisms of additional additives and approaches proposed in efficient low-Eg mixed Sn-Pb perovskite solar cells towards making highly efficient all-perovskite tandem solar cells.

Speech Topic: Metal-Organic Frameworks for Chemical Separations and Reactions: A Computational Perspective
Abstract: Metal-organic frameworks (MOFs) have emerged as a unique class of nanoporous materials and received tremendous interest over the last two decades. The variation of metal oxides and the judicious choice of controllable organic linkers allow the pore size, volume and functionality of MOFs to be readily tailored in a rational manner. Consequently, MOFs provide a wealth of opportunities for engineering of nanoporous materials and have been considered as versatile candidates for many important potential applications. Nevertheless, the number of MOFs synthesized to date is extremely large, thus experimental testing alone is economically expensive and practically infeasible. With rapidly growing computational resources, computational methods have become indispensable to characterize, screen, and design MOFs. In this presentation, I will give an overview of our recent computational studies on MOFs for chemical separations and reactions, such as carbon capture and utilization, biofuel purification, water desalination, chiral synthesis, etc. It will be demonstrated that computations at an atomic/molecular level can secure the quantitative interpretation of experimental observations, provide microscopic insight from bottom-up, and facilitate the development of new MOFs.
