Materials for Heat Assisted Magnetic Recording (HAMR)
Preview Available
The state of the art for current data storage is perpendicular magnetic recording technology. For continued increases in storage capacities, the next technology is heat-assisted magnetic recording (HAMR).
HAMR uses heat from a laser beam confined well below the diffraction limit to write media with such high magnetic anisotropy that they would normally be unwritable under available magnetic fields. The February, 2018 issue of MRS Bulletin introduced HAMR requirements and discusses its numerous interdisciplinary materials challenges. The talks in this webinar will expand upon the articles in the MRS Bulletin issue, and attendees will be able to interact—in real time—with the webinar presenters.
The following talks were presented in this webinar:
Dealloyed Nanoporous Materials with Interface-Controlled Behavior
Preview Available
Dealloying of alloys, the selective dissolution of less noble elements, can produce macroscopic samples that exhibit large surface-to-volume ratios and a uniform network structure with characteristic strut or “ligament” size in the nanometer range. The articles in the January, 2018 issue of MRS Bulletin highlight aspects of research into nanoporous metallic alloys fabricated by dealloying.
The talks in this webinar expanded upon the MRS Bulletin issue, and attendees were able to interact—in real time—with the webinar presenters.
Catalysts for Nanocarbon Growth
Preview Available
The November 2017 issue of MRS Bulletin reviews the genesis and development of nanocarbons over the last 50 years, focusing on the role of catalysts in their formation. The articles in the issue discuss the formation mechanisms and controlled growth of carbon nanotubes and graphene on substrates through catalytic processes.
The talks in this webinar complemented the articles in the MRS Bulletin issue, and attendees were be able to interact—in real time—with the webinar presenters.

Materials under Pressure
Preview Available
The October, 2017 MRS Bulletin issue on “Materials Under Pressure” focuses on several of the many and diverse domains of advanced materials research where the pressure (or stress) applied is used to alter or otherwise garner information on the material properties. Also included is an overview of research in which the application of high pressure—often combined with high temperatures and advanced analysis—has led to technological progress in the preparation of super hard materials. In addition, the response of materials such as glasses and perovskites to high stress conditions is discussed, and the structural, dynamical, and phase behavior of biological systems is considered. The talks in this webinar will expand upon the articles in the MRS Bulletin issue, and attendees will be able to interact–in real time–with the webinar presenters.

Single Atom Fabrication with Beams and Probes
Preview Available
The two current reigning paradigms enabling nanotechnology are scanning probe microscopy and molecular machine devices. Presently, the nanoscience and nanotechnology communities are seeing the emergence of a third paradigm—the use of the atomically focused beam of a scanning transmission electron microscope (STEM) to control and direct matter on the atomic scale. The September issue of MRS Bulletin presents advances in electron- and ion-beam-based atomic fabrication on surfaces, in layered materials, and in three dimensions. The talks in this webinar will expand upon the articles in the September MRS Bulletin issue, and attendees will be able to interact–in real time–with the webinar presenters.

Biomedical Applications of Magnetic Micro- and Nanoparticles
Preview Available
The use of magnetic micro- and nanoparticles for biomedical applications was first proposed in the 1920s as a way to measure the rheological properties of the cytoplasm. Since that time, particle synthesis techniques and functionality have advanced significantly. Magnetic micro- and nanoparticles are now used in a variety of biomedical applications such as targeted drug delivery, MRI contrast enhancement, gene transfection, immunoassay and cell sorting. More recently, magnetic micro- and nanoparticles have been used to investigate and manipulate cellular processes both in vitro and in vivo.
The webinar will focus on developments in Magnetically Activated Receptor Signaling (MARS)—a magnetic nanoparticle-based technique for activating cell surface receptors and controlling the activity of biomolecules such as growth factors. In addition, magnetic nanoparticle-based gene transfection and hyperthermia will be discussed.

3D Bioprinting of Organs and Organs-on-a-Chip
Preview Available
Three-dimensional (3D) printing and related additive manufacturing technologies have started to displace traditional manufacturing in a wide range of industries and applications. The August issue of MRS Bulletin highlights 3D bioprinting approaches, including advances and challenges in support materials and multimaterials printing, along with applications in tissue engineering and organs-on-a-chip. The talks in this webinar will expand upon the articles in the August MRS Bulletin issue, and attendees will be able to interact–in real time–with the webinar presenters.

Electron Emission Materials
Preview Available
The July 2017 issue of MRS Bulletin on Electron emission materials is inspired by the concept that new materials and physics can reinvigorate the field of electron emission. The possibility to exploit 2D materials for electron emission opens up new scenarios, which, in combination with different emission mechanisms, allows the possibility of advanced applications, some of which improve upon classical devices, and some that may not have been invented yet. The talks in this webinar will expand on the articles presented in the MRS Bulletin.

Next-Generation Materials for Synchrotron Radiation
Preview Available
New materials and improved existing ones are at the root of recent developments of new technologies for synchrotron storage rings and free-electron laser sources. The June, 2017 MRS Bulletin issue on Next-generation materials for synchrotron radiation explores several of these recent advances in materials for the optics, detectors, and other components that are essential parts of synchrotron systems for materials research. The talks in this interactive webinar expand on the material presented in the MRS Bulletin issue.
