Joining of Dissimilar Lightweight Materials


The transportation sector is the largest contributor to greenhouse gas emissions in the United States. Because it takes less energy to move a lighter object, even small reductions in weight can have a significant effect on the fuel consumption and emissions of the transportation sector. Lightweight materials of interest include advanced high-strength steel, aluminum, magnesium, polymer composites, and multi-material structures. Assembling multi-material structures is challenging due to differences in melting temperature, formation of intermetallic compounds, differences in coefficient of thermal expansion, and galvanic corrosion potential.

While the number of joining techniques available to the transportation industry grows, for high-volume production, there is a continued desire for a single joining method that can assemble advanced high-strength steel, aluminum, magnesium, and composite materials consistently and robustly.

The theme of the August, 2019 issue of MRS Bulletin is "Joining of Dissimilar Lightweight Materials." This webinar will expand upon the Bulletin issue, and an interactive Q&A session with the speaker will be held at the conclusion of the presentation.

Talk presentations:

  • Advances in dissimilar metals joining through temperature control of friction stir welding
    Kenneth Ross, Pacific Northwest National Laboratory
  • Ultrasonic welding of AZ31B magnesium alloy
    Jian Chen, Oak Ridge National Laboratory
  • Vaporizing Foil Actuator Welding
    Anupam Vivek, Ohio State University

Nanomaterials for Biomedical Applications


Nanotechnology has been responsible for an unprecedented positive impact in healthcare advances, by merging fundamental and applied sciences as complementary tools envisioning an enhanced quality of life. Recently, a broader spectrum of high performance nanomaterials and material-based nanosystems has been engineered to address challenges in medical and health-related fields. At the same time, there has been a shift in importance from designing exclusively bioinert materials to instead producing complex bioactive building blocks for mimicking targeted functions.

The June, 2019 Journal of Materials Research (JMR) Focus Issue is devoted to the latest advances in biomedical nanomaterials, including: (i) different fabrication approaches and applications, (ii) design and characterization of novel biomedical materials and devices as well as their structure-property relationships with biological responses, and (iii) novel (bio)-nanomaterials as potential candidates to integrate multifunctional devices targeting self-assembly materials.

The talks in this webinar expanded on the material presented in the Focus Issue, and an interactive Q&A session was held with the speakers following each talk.

Talks:

  • Electrochemical single-step obtention and characterization of a biomimetic TiO2-Hydroxyapatite NTs covered by chitosan
    Giovanna Machado, CETENE
  • Nanostructured surface coatings for titanium alloy implants
    Pierre Layrolle & Guy Louarn, University of Nantes
  • Assessing the Influence of Silkworm Cocoons’ age on the physico-chemical properties of silk-based materials
    Marisa Beppu, University of Campinas

Acoustic Processes in Materials


The coupling of acoustic energy with materials structures and processes is at the core of current and emerging application areas, such as ultrasound-enabled materials characterization, structuring, and processing. High concentration of acoustic energy has been shown to provide conditions for the synthesis of unusual material phases and structures, while reports on acoustic activation of surface diffusion, desorption, and catalysis hold high promise for applications where heating must be avoided or rapid switching of surface conditions is required. Some of the recent scientific and technical advances in the general area of acoustically enabled material synthesis, processing, and characterization are reviewed in the May, 2019 issue of MRS Bulletin.

The talks in this webinar expanded on the MRS Bulletin issue, and an interactive Q&A session was held with the speakers following each talk.

Talks:

  • Materials Synthesis in a Bubble
    Alfred Vogel, University of Luebeck
  • Transient Grating Spectroscopy: An Ultrarapid, Nondestructive Materials Evaluation Technique
    Cody A. Dennett, Massachusetts Institute of Technology
  • Acoustic Activation of Surface Processes - Desorption, Catalysis, and Diffusion
    Henry Helvajian, The Aerospace Corporation

Self-Assembled Porphyrin and Macrocycle Derivatives


The March 2019 issue of MRS Bulletin focused on recent developments in porphyrin nanomaterials, and their applications in energy harvesting and biomedicine. Porphyrins are plane macrocyclic molecules containing four pyrroles connected in ring fashion through four methine carbons at their α-positions. They are present in almost all living organisms in one form or another, such as chlorophyll and heme. Porphyrins are important participants in the energy supply system for both earth and life, in the forms of photosynthesis and oxygen transport. Porphyrin nanostructures can be synthesized by self-assembly methods and have various applications including in solar-energy harvesting, water splitting, environmental pollutant reduction, and nanomedicine for tumor therapy.


This webinar expanded on the Bulletin issue, and an interactive Q&A was held with each of the speakers following their talks.

Talks:

Size and Shape-dependent Photocatalysis of Porphyrin Nanocrystals
Feng Bai, Henan University

Porphyrin-based Nanocomposites for Tumor Photodynamic Therapy
Bingbo Zhang, Tongji University

Binary Ionic Porphyrin Self-Assembly: Structures, Electronic and Light Harvesting Properties

Bio-inspired “Far From Equilibrium” Materials


The creation of new materials capable of performing life-like functions inspired by biology, such as complex and cooperative processes, self-replication, and self-repair, will ultimately rely upon incorporating biological principles of spatiotemporal modes of self-assembly. Elucidating fundamental principles for the design of such out-of-equilibrium dynamic self-assembling materials systems is the focus of the February, 2019 issue of MRS Bulletin.

This webinar expanded on the Bulletin issue, and an interactive Q&A was held with each of the speakers following their talks.

Mechanical Behavior of Nanocomposites


By engineering the length scales, morphology, crystallography and chemistry of interfaces, nanocomposites can deliver mechanical properties that exceed what could be achieved from a single-phase material alone. The January, 2019 issue of MRS Bulletin  highlights recent developments in mechanics of nanocomposites that are composed of a combination of metallic, polymer, biological, and ceramic materials and outline the challenges and opportunities for future research directions.

This webinar expanded on the Bulletin issue, and an interactive Q&A was held with each of the speakers following their talks.

Piezotronics and Piezophototronics


Piezotronics and piezophototronics are two newly coined fields for third-generation semiconductors that actively couple the strain-induced polarization potential with the mobile charge carrier transport behavior. The fundamental effects are likely to impact the design and fabrication of electronic and photonic devices for mechanosensation, human-machine interfacing, robotics, artificial intelligence, sensors, LEDs, solar cells, and catalysis. The December, 2018 issue of MRS Bulletin highlights the progress made in these two fields.

This webinar will expand on the Bulletin issue, and an interactive Q&A will be held with each of the speakers following their talks.
