Current Research

Dr. Moon is an internationally recognized researcher in cellulose nanomaterials (CN). He is an expert in processing-structure-property relationships as they apply in various aspects of CN research, such as, nanocomposites, hybrid composites, recyclable solar cells, multi-scale modeling, characterization, etc.. His research program on nanoscale science and engineering of CNs are highly collaborative with Purdue University and Georgia Institute of Technology (GT), where he holds Adjunct Professor appointments in both the School of Materials Engineering (at Purdue University), and in the School of Materials Science and Engineering (at GT). Dr. Moon a member of and is currently stationed at the Renewable Bioproducts Institute at GT.

Dr. Moon works to develop cellulose nanomaterials (CN) pre-structures (e.g. films, continuous fibers, spheres, etc.) combined with targeted CN surface treatments to produce industrially relevant CN composites with improved performance (thermo-mechanical properties, etc) and new functionality/capabilities (e.g., antimicrobial, current conduction, etc.). Resent work has been in the areas of new cement systems, flexible electronics, and functional fillers in various polymer systems.

Past Research

Improved Fracture Toughness of Ceramics by Structural Design: 1997-2005

Ceramic materials are increasingly being used in applications with extreme environments (e.g., wear, high temperatures, etc.), but they are brittle, cracking easily. There is a need to improve their durability. During his PhD and Post Doctorial studies, the Dr. Moon completed cutting-edge research in knowledge discovery on making ceramics more difficult to break via ground breaking investigations into how cracks grow. Through design of ceramic composites, the Dr. Moon focused on three key mechanisms for impeding crack growth; weak interlayers, residual stress, and graded layers (e.g., change in composition vs position). This work resulted in 17 publications.

  

Knowledge Synthesis and Assessment of Cellulose Nanomaterials: 2010-2018

Dr. Moon strives to digest down the culmination of many studies and complex ideas regarding Cellulose nanomaterials (CN) into basic constructs, describe these in simple relevant terms, maintaining content consistency and integrity, and writing in a style that engages a wide spectrum of readers from various disciplines & level of expertise who are reading to be introduced to CNs or gain some new insights about the key concepts of these materials. Dr. Moon has co-lead three key publications in this area.

Chemical Society Reviews 47:2609-2679 (2018).

How Stiff and Strong are Cellulose Nanomaterial: 2007-2018

Cellulose nanomaterials (CNs) have big gaps and reliability issues in their reported properties, a consequence of their extremely small size, and the ordered bundling of cellulose chains along the CN length, which results in large differences in properties depending on the measurement direction (e.g. property anisotropy). Dr. Moon used Atomic Force Microscopy (AFM) and atomistic modeling to assess properties of nanoscale sized particles and elucidate the mechanisms giving rise to uncertainties. This work provided the first experimental measurement of stiffness in the transverse direction of CNs. This work resulted in 11 publications.

    Dr. Moon provides the direction, vision, and sets the goals of the division, and plays a central role in directing/shaping the content of the NANO conference. The NANO conference is the NanoDivision’s annual conference “The International Conference in Nanotechnology of Renewable Materials”, which is the preeminent international technical conference on the production, research, development, and application of cellulose nanomaterials. Under Dr. Moon’s leadership, the NanoDivision (initiated in 2011) has grown in membership, become self-sustaining, expanded beyond the pulp and paper disciplines and industries, expanded informational outreach, and expanded the content and grew attendance of the annual NANO conference. Dr. Moon led the development of a new organizational structure consisting of a leadership team and 5 committees (e.g., Producers, End-Users, Research, Student, and Webinar) that execute specific functions of the NanoDivision, its outreach and the organization and plan
