Featured symposium

November 27 – December 6, 2023

Symposium CH02 - Advances in In Situ TEM Characterization of Dynamic Processes in Materials

Co-organizer: Dongsheng Li

Invited speaker: James De Yoreo

Summary: The symposium covers a broad range of topics, including particle nucleation and growth, phase transformations, and interface dynamics with gases, liquids, and solids. This symposium aims to provide a platform for discussion to understand the physical and chemical processes governing the dynamic process of behavior under different external stimuli using in situ TEM, as well as computer-aided image analysis and data processing, (e.g. artificial intelligence algorithms).

Selected PNNL presentations

Tuesday, November 28

An In Situ Look at Interfacial Controls on Crystal Nucleation and Assembly

Session: 8:30 – 9:00 a.m. EST, Location: Sheraton, Second Floor, Republic A

PNNL Presenter: James De Yoreo

Summary: The results of this study reveal the importance of surface charge, organic ligands, chemical gradients, and solvent organization near interfaces in determining how ordered solids emerge from the solution.


Peptoid-Controlled Synthesis of Hierarchical Composite Nanomaterials

Session: 8:45 – 9:00 a.m. EST, Location: Hynes, Room 101

PNNL Presenter: Chun-Long Chen

Summary: To develop self-assembling peptoids for controlled formation and morphogenesis of hierarchical composite nanomaterials, a combination of in situ imaging and molecular simulations were used to elucidate the principles underlying peptoid-controlled inorganic crystallization with the ultimate goal of enabling predictive materials synthesis across scales.


Liquid Electrolytes and Solid Electrolytes for High-Energy Lithium Batteries

Session: 9:00 – 9:30 a.m. EST, Location: Hynes, Level 3, Room 304

PNNL Presenter: Jun Liu

Summary: Batteries play a critical role in modern society. The electrification of transportation and deep decarbonization require the development and deployment of high-energy, low-cost battery materials and technologies.


Solvation Directed Dimensionality and Hierarchy Control in Solution Synthesis of Nanomaterials

Session: 9:00 – 9:15 a.m. EST, Location: Sheraton, Second Floor, Republic A

PNNL Presenter: Maria Sushko

Summary: The development of structural hierarchy on various length scales during crystallization process is ubiquitous in biological systems and is common in synthetic nanomaterials. The driving forces for the formations of complex architectures range from local interfacial interactions that modify interfacial speciation, local supersaturation, and nucleation barriers, to macroscopic interparticle forces.


Understanding the Atomic Scale Mechanisms of Oxidation and Hydrogen Embrittlement of Nuclear Structural Materials using In Situ and Cryogenic Transfer Atom Probe Tomography

Session: 10:00 – 10:30 a.m. EST, Location: Sheraton, Third Floor, Dalton

PNNL Presenter: Arun Devaraj

Summary: When nuclear structural materials, specifically stainless steel, are subjected simultaneously to applied tensile stress and a corrosive, high-temperature water interplay of hydrogen and oxygen interactions with the alloy microstructure are thought to lead to intergranular stress corrosion cracking. Despite decades of research on stress corrosion cracking mechanisms of stainless steel, crucial knowledge gaps remain about the atomic scale mechanisms responsible for intergranular oxidation and hydrogen embrittlement.


Emulating Nature’s Way of Making Materials

Session: 10:15 – 10:45 a.m. EST, Location: Hynes, Level 1, Room 101

PNNL Presenter: James De Yoreo

Summary: From harvesting solar energy to capturing carbon monoxide and purifying water, living organisms have solved some of the most vexing challenges now faced by humanity. They have done so by creating a vast library of proteins and other macromolecules that can assemble into complex architectures and direct the mineralization of inorganic components to produce materials characterized by a hierarchy of structure.

Assembly of Sequence-Defined Peptoids into Crystalline Nanomaterials as Biomimetic Catalysts

Session: 4:00 – 4:15 p.m. EST, Location: Sheraton, Second Floor, Republic A

PNNL Presenter: Chun-Long Chen

Summary: While natural enzymes, including lignin peroxidase, phosphotriesterase, and carbonic anhydrase, are promising for various applications, such as lignin depolymerization, degradation of toxic organophosphates, and accelerated carbon monoxide precipitation, there are numerous key technical barriers to prevent their practical applications, because they often suffer from low stability and high cost.
