book cover

Innovation and breakthrough approaches that benefit humanity start with an idea. Your ability to advance your ideas depends in part on whether you can convince decision makers and cross-disciplinary team members to support the work. Yet communicating to non-expert funders, managers or colleagues is often where technologists fail.
Amy and Roger Aines reveal why, and what can be done to change the outcome. In this talk, they will share insights and strategies from their research for writing Championing Science – Communicating Your Ideas to Decision Makers. They will explain how engineers can leverage skills in research, observation, experimentation, and the influence process, to make sure their ideas are heard.

Electron backscattered diffraction (EBSD) is a rapidly developing technique in the material characterization field. The technique gives microstructure information in the meso-scale which includes grain size, crystal orientation, grain boundaries, dislocations, and phase identification that all contribute to the device performance and reliability. Typical components that benefit from the EBSD analysis includes bond pads, solder joints, thin wires and capacitors. Electron channeling contrast imaging (ECCI) is a derivative technique from EBSD that gives quantitively defect density measurement of single crystals. The scanning area is on the order of several tens to hundreds of micrometers making this measurement ideal for high quality crystals (defect density 108/cm2 to 105/cm2).

Dr. Jingyi Zhang 
is an EBSD Scientist at EAG Laboratories, which she joined in 2018 after completing a doctorate in Mechanical Engineering at Washington State University.

The demand for storing electricity is growing more rapidly than ever with the increased use of the mobile Internet of Things (IoT) devices and electric vehicles. Thus, safe and cost-effective batteries with high energy density are drawing significant interest in the field.
In this presentation, a sustainable method to develop battery electrode materials will be presented. By using biomaterials, a rod shape virus (M13 bacteriophage) or a cylindrical shape microbe (Escherichia coli, called as E. coli), the electrodes for lithium-based batteries were fabricated in an environmentally friendly way. Through the interaction between precursor ions and protein assemblies of virus molecules, a wide range of transition metal oxides nanowires has been synthesized at room temperature under aqueous synthesis conditions. Besides, microbes were used as a pore template to create an interconnected pore structure by using lengthy E. coli. These biotemplates are about one million times cheaper and are easier to remove than synthetic porogens such as silica or polystyrene beads.
The battery electrodes made in a bioinspired method have presented significant performance improvements in Li-ion batteries as well as Li-oxygen batteries. We believe that biomaterials driven material research can provide an efficient and environmentally benign way to build a high-performance device, in particular, next-generation energy storage system.

Keynote Lecture: Additively Manufactured Biomimetic Polymers

Dr. Ozgur Keles, Chemical and Materials Engineering Department, San Jose State University
Register: Here
Additive manufacturing (AM) is increasingly used for biomedical, automotive, space, defense, transportation, and consumer product applications. Fused deposition modeling (FDM) is most common AM technique that can produce polymer, composite, metal, and ceramic materials. FDMed materials, however, contain pores between the deposited beads. Moreover, we can intentionally add pores to any kind of design to decrease weight or to add functionality, such as heat or mass transport. These pores reduce mechanical properties and introduce variations in mechanical properties. Despite the increasing use of FDM, the effect of porosity on the mechanical behavior of FDMed materials are unclear. Our recent work showed that intentional vibrations or biomimetic deposition paths can be used to double mechanical reliability of FDMed polymers and polymer matrix composites. In this talk, I will discuss the origins of the mechanical reliability in porous polymers and deviations from Weibull statistics. In addition, I will detail how we can improve strength and toughness of porous polymers. Biomimetic meso-structure and vibration-assisted FDM approaches will be described to improve reliability in FDMed materials.

X-ray Fourier Holography Takes Off

     Most of our high-resolution imaging methods have to compromise between temporal or spatial resolutions, similar to a pinhole camera. If the entrance pinhole is very small, the resulting image is crisp, but requires a long exposure and thus, is less suitable to capture moving objects. One can increase the pinhole diameter and thus, increase the temporal resolution, but this comes at a cost of the sharpness of the image.
     Of course, our microscopic tools have greatly evolved over time, but this original problem still limits our capabilities to observe fast processes at the nanoscale. Examples include chemical and catalytic reactions, nucleation dynamics and growth of nanoparticles, and other phenomena which are short-lived. One idea to overcome this obstacle is to use an illumination source, which is capable of producing intense short wavelengths radiation such as X-rays within very short exposure times.
     X-ray Free Electron Lasers (FELs), such as the LCLS at SLAC, are capable of producing very bright bursts of coherent X-rays within a few femtoseconds. This large-scale technique offers unique opportunities to visualise fast processes via coherent X-ray diffractive imaging. Coherent X-ray diffractive imaging, however, suffers from intrinsic loss of phase, and therefore structure recovery is often complicated and not always uniquely-defined. Here, we introduce the method of in-flight holography, where we use nanoclusters as reference X-ray scatterers in order to encode relative phase information into diffraction patterns of a virus. The references (small spherical nanoparticles) and the bio samples are injected into random positions within the FEL focus. Using in-flight holography, we were able to reconstruct the unknown relative orientation of the reference and the sample. In a second step, we used Fourier X-ray holography to reconstruct the shape of the specimen.
In my talk I will report on several studies exploring the in-flight holography principle. Moreover, I will discuss future capabilities and applications for X-ray FELs and the possibility of future table-top experiments.

Dr. Gorkhover was one of four SLAC scientists to win the Department of Energy’s Early Career Research Program award in March 2018. In 2016, she was the first female scientist to receive the Panofsky Fellowship, named after the laboratory’s founder and first director.

     “I’m interested in developing new imaging methods that are becoming possible because of XFELs,” says Gorkhover. “My main motivation is to see how we can use this exciting technology to learn about the behavior of complex nanoscale systems.”

X-Rays Reveal the Secret Life of Batteries

     Hard X-ray transmission X-ray microscopy (TXM) is an ideal tool for in situ and operando studies of functional materials and materials synthesis routes. The high energy X-rays provides relatively relaxed restrictions on in situ environments enabling high resolution 2D microscopy and tomography (3D microscopy) across a large range of pressures and temperatures and in varying gas or liquid environments. The full field geometry of TXM allows imaging at the sub-second time scale, allowing relevant dynamics to be captured during, for example, battery cycling, catalysis reactions, electrochemical synthesis, and corrosion. Moreover, by tuning the incident X-ray energy to specific absorption edges, TXM can capture elemental and chemical (spectro-microscopy) changes at 30 nm resolution within a few minutes (see figure).
Li-ion batteries promise the high specific capacity required to replace the internal combustion engine with a number of possible earth abundant electrode materials; however, setbacks such as capacity fading hinder the full capability of these rechargeable batteries. In the search for better electrode materials, high resolution X-ray microscopy during typical battery operation is vital in understand and overcoming the failure mechanisms of these materials. I will discuss the use of X-ray microscopy including spectro-microscopy and nano-tomography to track electrochemical and morphological changes in the electrode material in real time during typical battery operation.
