Biological & Biomimetic Materials

Biological and bioinspired materials are complex as they naturally contribute to environments that “grow and develop.” In this session, we will curate and discuss topics related to the crystallization of biological or biomimetic materials as well as self-assembly mechanisms. This includes, but will not be limited to: assembly and / or function of organic (e.g., polysaccharides, proteins, peptides, peptoids, polymers, DNA and RNA) materials, and nucleation, growth and phase transformations in biological or biomimetic materials as well as the subsequent impact on performance. In addition, interactions at the inorganic-organic interface, biomimetic crystallization, bioinspired synthesis, in silico modeling of crystallization of biological structures and synthetic materials, as well as methods to characterize these biological materials and interfaces will be discussed. Past investigations into these biological interfaces and materials are limited by the sensitivity of standard methodologies, lacking the necessary temporal and spatial resolutions. Moreover, multiple techniques may be required to understand the organization and activity of these materials in their native states. To concisely characterize and measure properties of these model systems, novel toolsets are required to accurately access ranges of time- and length- scales which are physiologically-relevant. In this interdisciplinary session, state-of-the-art experimental procedures and theoretical approaches will be discussed and thereby further the understanding of fundamental principles as well as the possibilities for various applications. Plenary talks and posters will be organized into three correlated topics in this session: (A) Biological and Biomimetic materials (B) Energy and Environmental Materials (C) Fundamentals of Bio-crystallization If there are any questions/suggestions regarding this session, please do not hesitate to contact the organizers.
Boron Nitride Epitaxial Growth & Characterization Symposium

Boron nitride (BN) has recently emerged as a material of choice for a wide array of technologically important application areas including deep-UV optoelectronics, power/RF electronics, neutron detectors, single photon/electron emitters, and super-capacitors. BN exists in three different crystalline forms: hexagonal, cubic and wurtzite resulting in a wide range of material properties, quite in analogy to carbon taking on a wide range of extreme properties resulting from structures ranging from diamond to graphite to graphene. Despite BN’s exciting material properties, the full potential of BN has yet to be realized at scale due to challenges in its large area, high quality, reliable synthesis in the desired polymorph. A lack of native substrates requires sophisticated approaches to overcome challenges brought on by heteroepitaxial constraints. This symposium explores recent advances in boron nitride synthesis (all polymorphs) with a particular focus on its epitaxial growth. Resulting material properties and defects will be discussed along with general characterization of this material and determination of metrics to assess ‘quality’ of synthesized materials.


Bulk Crystal Growth

This symposium will cover bulk crystal growth of a variety of materials from liquid and vapor phases. The topics of interest include, but are not limited to: melt growth, solution growth, physical vapor transport, and other bulk vapor grown techniques such as hydride vapor phase epitaxy (HVPE). Applications include, but are not limited to: semiconductors, detectors, laser host, and non-linear optical materials. The session is interested in papers related to crystal growth methods, innovative growth techniques, analysis of interface shape, the incorporation of impurities, characterization and elimination of defects, enhancements in size, properties and performance, fabrication techniques, and new materials. This cross-disciplinary session will provide an opportunity as a forum for business and academia to share research results and exchange ideas in bulk crystal growth.
Fundamentals of Crystal Growth
(Ken Jackson Session)

A diverse range of technologies continue to rely on the understanding of science principles that govern crystal growth. In several instances, advances in these fundamental aspects are enablers for emerging industrial applications of crystalline materials, and for engineering biomimetic growth strategies at the intersection of nature and technology. In this symposium, we bring together leading experts from academia, government laboratories, and industry to present key advances in all aspects of crystal growth in a wide range of material systems. The symposium will consist of invited specialists, presentations, and poster sessions. Topics of interest include (but are not limited to): 1) Fundamentals of nucleation and crystal growth 2) Bulk and thin film crystal growth, including aspects related to orientation/texture 3) Stress and morphological evolution during growth 4) Effect of impurities, surfaces, interfaces and related extended defects 5) Novel advances in growth of metals and alloys and ceramics, 6) Crystal growth at the nanoscale and low dimensional systems 7) Crystal growth of emerging active materials (topological insulators, quantum materials) 8) Data-enabled fundamental advances in crystal growth 9) Crystallization in soft (polymeric and biological) material systems 10) Experimental and characterization techniques for crystal growth (including ICME strategies) 11) Crystal growth via particulate and/or additive manufacturing techniques
Modeling of Crystal Growth Processes

Mathematical analysis and computational modeling are essential tools of inquiry for fundamental issues in crystal growth as well as for the design, optimization, and control of crystal growth processes. This symposium encourages the submission of presentations that discuss the development of computational models and simulations, their implementation and application, and the new understanding that emerges. The scope of the symposium is intended to be broad and will span modeling at all length and time scales, ranging from quantum mechanical studies to classical molecular simulations to continuum techniques. With the aim of emphasizing the cross-disciplinary nature of computational work, this symposium seeks to serve as a hub for modeling and simulation presentations submitted to other ACCGE/OMVPE symposia, where modeling results may be applied to advance the understanding of the materials or growth processes that are featured in that session. Papers discussing advances in modeling and simulation approaches and techniques are also encouraged and will grouped in the program according to their focus.
Reduced Gravity Symposium
It has long been established that the force of gravity can influence heat and mass transfer processes that occur during crystal growth through effects such as buoyancy convection and sedimentation. Microgravity experimentation provides a means to study these effects in the near absence of gravitationally induced flows. This symposium will bring together researchers from academia, government and industry to disseminate information both on the results of crystal growth experiments in reduced gravity and on projects that are currently under development. Papers on ground-based results from experiments that are leading up to flight investigations are also welcome. Also encouraged are presentations of technology and hardware developments, as well as modeling efforts, particularly those that elucidate the effects of steady and non-steady (g-jitter) effects on crystal growth processes.
Seventh Symposium on 2D and Low Dimensional Materials



7th Symposium on 2D and Low dimensional Materials Research on the synthesis and the applications of various low-dimensional materials (0D, 1D, and layered 2D materials) are the themes of this symposium. The unique properties of these materials, differing or exceeding those of their bulk crystal counterparts, are of potential scientific and technological importance. Materials of central importance to this symposium include 2D layered materials such as graphene, boron nitride, transition metal dichalcogenides and oxides, topological insulators, superconductors, Xenes, etc., as well as their 0D and 1D counterparts, and various heterostructure combinations.
