Actinides and Rare Earths (AC)
Actinides and rare earths exhibit many unique and diverse physical, chemical and magnetic properties resulting in large part to the complexity of their 5f and 4f electronic structure. The Actinide and Rare Earth Focus Topic Sessions focus on the chemistry, physics and materials science of f–electron materials. Emphasis will be placed upon the 4f/5f electronic and magnetic structure, surface science, thin film properties, and applications to energy–related issues. The role of fundamental f–electron science in resolving technical challenges posed by actinide materials will be stressed, particularly with regard to energy applications, including energy generation, novel nuclear fuels, and structural materials. Both basic and applied experimental approaches, including synchrotron–radiation-based and neutron–based investigations, as well as theoretical modeling computational simulations, will be featured to reconcile the observed behavior in these complex materials. Of particular importance are the issues important to nuclear energy and security, including fuel synthesis, oxidation, corrosion, intermixing, stability in extreme environments, prediction of properties via bench-marked simulations, separation science, and forensics. Specific sessions will be devoted to a continued, focused emphasis on the advances in the theory and measurements of core-level spectroscopies for the study of actinides and rare earths. Focus Topic emphasis will address advances in chemistry/materials sciences for environmental management and the participation of early career scientists. The shared sessions will be with Applied Surface Science, Magnetic Interfaces/Nanostructures, and the Synchrotron Radiation and FEL Focus Area.
This Focus Topic will highlight progress in nanometer and atomic scale fabrication processes leveraging focused electron beams and scanned probe techniques as manipulation tools. Topics will include 3D nanoprinting, single atom manipulation, feedback control and automation, and atomic-scale device fabrication.
As the cutting edge of manufacturing edges into sub ten-nanometer length scales, subtractive processes such as lithography will become inadequate for many applications, motivating nanoscale additive processes. Analogous to macroscopic Additive Manufacturing, micro- and nanoscale additive manufacturing is becoming commonplace with E-beam/ion-beam induced deposition (E/IBID) used routinely in dual beam systems as a miniaturized “welding” method for sample preparation. Additionally, scanned probe techniques have shown demonstrations of additive manufacturing by various methods. Controlled movement of single atoms and construction of materials/molecules atom-by-atom hold great promise for future nanotechnology and miniaturization, both with scanned probe as well as electron beam techniques. Here, we will highlight the recent progress in this field and provide a forum for researchers to push the boundaries of additive manufacturing to the ultimate precision at the atomic level.
The newly emerged field of nanophotonics have recently brought considerable interest in developing photonics-based nanodevices for various metrology solutions, which have the potential to outperform and replace legacy based metrology. The “Advances in Nanophotonics Metrology” (AN) focus topic will highlight the challenges and the latest development in nanophotonics metrology. It will cover various sensing application such as metrology of physical, chemical and biological properties, frequency synthesis on a photonic chip, and cold-atom based nanophotonic sensors.
The Spectroscopic Ellipsometry Focus Topic integrates themes ranging from classical material science and thin film characterization to nanometer scale science and novel optical sensing concepts. We will host two oral sessions dedicated to traditional applications of spectroscopic ellipsometry in optical materials and thin film characterization as well as new and emerging topics. The first session will focus on classical research topics of ellipsometry as for instance optical coatings and inorganic thin films characterization. Furthermore, presentations on the ellipsometric investigation of novel optical and electronic materials and materials with subwavelength structures will be included. In the second oral session, we will host presentations on novel experimental and theoretical approaches including for instance imaging ellipsometry or optical critical dimension analysis techniques. The oral sessions will be anchored by two outstanding invited speakers Prof. Mathias Schubert, University of Nebraska-Lincoln and Prof. Vanya Darakchieva, University of Linköping, Sweden. As a highlight of our Spectroscopic Ellipsometry focus topic, the best student paper, which is selected based on the quality of the research, its presentation, and the discussion during the symposium, will be awarded with the Spectroscopic Ellipsometry Focus Topic student award. Spectroscopic Ellipsometry will also host a poster session.

The IPFs, scientific gatherings sponsored by the American Institute of Physics and hosted by its member societies, are unique, topic-specific conferences addressing application-focused research in the physical sciences emerging from academia and the private sector. They consist solely of invited talks grouped around several subtopics. The present Forum, the seventh at AVS since 2006, focuses for the first time exclusively on the biophysical/medical sciences and is co-hosted by the Biomaterials Interfaces Division (BID). The program was designed to broaden the interest and perspective of the BID community through talks partially overlapping research areas of their interest, yet not routinely covered at prior AVS Symposia. The program focuses on innovations in three sub-topics of the biosciences: imaging and structural determination, bioanalytic sensing and diagnostics, and biomaterial assembly. Each topic is covered by five invited speakers in three consecutive morning sessions starting Monday October 22. The afternoons are set aside for contributed talks on topics related to the respective morning sessions. The event is preceded by the traditional BID Plenary session on Sunday afternoon October 21, with topics complementary to those of the IPF.
The session on imaging and structural determination highlights diverse experimental approaches based on infrared, visible, X-ray and mass spectrometric technologies, and encompasses advanced nonlinear optical, fluorescence and Raman spectroscopy, as well as synchrotron and X-ray free electron laser (XFEL) studies for dynamic and 3D imaging of biomolecules and sub-cellular structures at nanoscale resolution. The bioanalytic, biosensor and diagnostic session covers diverse sensing approaches from activated surfaces to discreet nano-sized biomolecular and patterned structures. Topics include advances in in-vitro and in-vivo approaches to disease detection, nanoparticles for monitoring biomolecular functions in their biological environment, subcellular sensors to probe biological processes in live cells, and sensitized surfaces acting as pressure and tunable photo-responsive sensors. The biofabrication session encompasses a structured build-up from basic tissue assembly to the prospects of full organ fabrication. The intermediary steps of vascular co-assembly and its accompanying challenges of supplying life sustaining nutrients and oxygen to the living cells will be amply covered. In addition, the scaffolding required to maintain the integrity of the assembling organ will be discussed, as well as the different approaches and challenges in 3D printing.

Since traditional computing systems have begun to reach the theoretical limits of their performance, alternative, biologically inspired approaches to computing have become increasingly important. These neuromorphic computer systems often require new devices and materials beyond those typically available in traditional CMOS and semiconductor foundries and have both reconfigurable and continuously tunable properties. This Focus Topic will explore both the new materials used in these next generation systems as well as nanoscale, integrated demonstrations of next generation computing systems.
Advanced scattering, diffraction, spectroscopic and imaging techniques developed at electron accelerator based X-ray light sources have made revolutionary contributions to understanding of structure-dynamic-function relationships in various complex functional materials where interfaces are an inherent feature. At AVS 65th dedicated to processing and interfaces for the IoT era this topical session will provide a forum for communicating the latest research paradigm in exploration of complex interfacial systems that have allowed to go beyond periodic and equilibrium structures for obtaining unprecedented insights into the relationships between synthesis, processing and properties that enable the desired functionality. The selected topical presentations will illustrate the unique opportunities, opened by several novel tools for in-situ studies, to uncover peculiar atomic arrangements and composition profiles across the interfaces and explore how the interfacial structure and functionality respond to external stimuli such as temperature, electric or magnetic field, light and changes in the chemical composition by exposing to various environments.
