The use of X-ray footprinting mass spectrometry (XFMS) to investigate structural features and conformational changes of macromolecules in the solution state has grown substantially in the past decade and has been successfully applied to systems ranging from single domain proteins to in vivo ribonucleoprotein assemblies. The method is highly complementary to the more widely used structural elucidation techniques for biological macromolecules such as x-ray diffraction, HDX, and cryo-electron microscopy. XFMS is an in situ hydroxyl radical (•OH) labeling method; X-ray irradiation dissociates solvent water to produce hydroxyl radicals, which covalently modify side chains which are solvent accessible. More specifically, residues which are in proximity to water molecules (either bulk or bound) are modified to a greater extent than residues which are not in proximity to water. Because liquid chromatography-mass spectrometry is then used to analyze the stable covalent modifications produced, the data provide a “water map” at the single residue level, which is then used to determine sample conformation. In this talk, I will describe the XFMS method, its advantages and disadvantages relative to other methods, recent technological advances in the method, and some recent exciting examples of structural information obtained on protein systems using the method.

The coronavirus disease 2019 (COVID-19) has created an acute worldwide demand for sustained broadband pathogen suppression in households, hospitals, and public spaces. The US recently passed a new sad milestone of 500,000 deaths due to COVID-19, the highest rate anywhere in the world. In response, we have created a rapid-acting, self-sterilizing copper material capable of killing SARS-CoV-2 and many other microbes in seconds. The highly active material destroys pathogens faster than any conventional copper configuration. The material maintains its antimicrobial efficacy over weeks and is shelf stable. We have performed rigorous testing in accordance with guidelines from U.S. governing authorities and believe that the material could offer broad spectrum, non-selective defense against most microbes via integration into masks and other protective equipment. The presentation will provide a detailed view into the “inner” workings of the material including the underlying mechanical details that make this high efficacy possible.
Dr. Alfred Zinn is founder and CTO of Kuprion Inc., a materials company principally engaged in the manufacture and application of engineered copper materials for a wide variety of applications such as surface mount technology, packaging, printed circuit board assembly, printed electronics, 3D printing, injection molding and many thermal applications with special focus on copper-based nanomaterials. The latter are fused to bulk copper to take advantage of the low processing temperatures, and the high electrical and thermal conductivity of bulk copper. Since the onset of the Covid-19 pandemic, Dr. Zinn and the Kuprion team have been investigating ActiveCopper (aCu) as a powerful antimicrobial. aCu has been successfully tested against Gram-negative and positive bacteria, non/enveloped viruses including SARS-CoV-2, and multiple resistant strains of bacteria (“superbugs”). In all instances it kills pathogens in 1 minutes or less, which is an unprecedented level of efficacy for copper. With these extraordinary findings, Dr. Zinn has submitted the material for EPA registration for incorporation into PPE such as masks, gloves, and surface coatings.
Alfred received his Doctor of Science degree in Chemistry in 1990 from the Philipps University, Marburg, Germany. Prior to his current position, Dr. Zinn was a Lockheed Martin Fellow at the Advanced Technology Center (ATC) of the Lockheed Martin Space System Company, in Palo Alto, CA. He holds over 40 patents in materials, structures and processing technologies and THz technology. He has authored or coauthored over 30 archival journal publications, including book chapters in “The Chemistry of Metal CVD” as well as the “Encyclopedia of Inorganic Chemistry.” Over the past two decades, he has presented his technical results and accomplishments at many national and international Conferences.

3D optical profiling is a noncontact, high-resolution measurement and visualization technique used to measure the topography and geometry of devices and materials. Capabilities of commercial 3D interferometry systems have steadily improved; today, they can measure vertical nano- and microtopography spanning Ångstroms to many millimeters in length scale. True Color imaging, developed by KLA, provides additional understanding that is complimentary to topography. Advances in optomechanical hardware, optics, electronics, and software now make it possible to create economical precision 3D interferometric measurement systems, enabling 3D profiling to help a broader range of industrial and scientific applications. This talk provides an example of how the capabilities of this new generation of 3D optical measurements can be applied to the fields of printed and flexible electronics. Flexible electronics is characterized by a rich and diverse set of functions, device topographies, fabrication technologies, and various materials (conducting, insulating, dielectric, etc.), which have complex surface structures with diverse optical properties. Multiparameter printed arrays on flexible substrates can be used for sensing humidity, temperature, and mechanical strain, as well as for thermoelectric generators and many other purposes, all of which have performance dependencies upon geometry and fabrication process. Ultraviolet germicidal irradiation (UVGI) N95 filtering facepiece respirator (FFR) treatment is considered an effective decontamination approach to address the supply shortage of N95 FFRs during the ongoing Covid-19 pandemic. We investigated the nanomechanical and non-contact 3D optically-measured topographic properties of filtration fibers that have been exposed to different doses of UVC radiation. UVC exposure was shown to decrease both Young’s modulus (E), hardness (H) and fiber width, as measured on individual polypropylene (PP) fibers. Our results also show that the PP microfiber layer loses its strength when N95 respirators are exposed to an accumulated UVC dose during the process of decontamination, and the PP fiber width also exhibits a logarithmic decrease during UVC exposure. The nanoscale measurement results on individual fibers suggest that maximum cycles of UVC disinfection treatment should be limited due to excessive accumulated dose, which has the potential to decrease the fiber breaking strength. This talk will discuss examples of how optical and nanomechanical characterization can improve understanding of devices and materials, including the above topics, and more.

In the past five decades, the semiconductor industry has gone through two distinct eras of scaling: the geometric (or classical) scaling era and the equivalent (or effective) scaling era. As transistor and memory features approach sub-10 nanometer, it is apparent that room for further scaling in the horizontal plane is running out. Further, the rise of data abundant computing is exacerbating the interconnect bottleneck that exists in conventional computing architecture between the compute cores and the memory blocks. In this talk, I will discuss how electronics is poised to enter a new, third, era of scaling – hyperscaling – in which resources are added in a flexible way when needed to meet the demands of data abundant workloads. This era will be driven by advances in embedded non-volatile memories, hybrid devices with merged logic and memory functionalities, monolithic three-dimensional integration, and heterogeneous integration techniques.

Printing technology has evolved from traditional quick writing tools to the modern
manufacturing methods for functional devices and systems. The benefits of printing-based
manufacturing include less material waste, fast-turn around prototyping due to simple
design customization and wide substrate compatibility. In this presentation, all-printed
supercapacitors, where all the components are made by printing, are introduced. Because
the device is manufactured only by printing, the complexity of manufacturing facilities can
be minimized and the resource efficiency and versatility are maximized, which are
particularly important in places where the supply of material and human resources are
limited such as rural areas, environmental monitoring of nuclear sites and space exploration
missions. We have fabricated electrical double layer capacitors and pseudocapacitors, both
with high electrochemical performance and cyclic durability and the results will be discussed
in detail.

ABSTRACT
In this talk, I will present our Laboratory work on highly-quantitative plasmonic sensing based on Surface Enhanced Raman Spectroscopy (SERS). I will first describe our nano-imprinted SERS substrate architecture and performance. Then I will show how inkjet dispensing can be used in conjunction with SERS to encode each sensor with a calibration pattern of microdroplets (~30 pico-liters), with the aim of locally calibrating sensor performance. This way, we demonstrate that Measurement Uncertainty of the SERS signal can be reduced below 2%, which to our knowledge, is a new record for plasmonic sensing platform. Furthermore, the use of inkjet dispensing in combination with Raman mapping improves assay throughput (100-fold) and reduces sample volume consumption (105-fold) in an automated and reproducible fashion. Since this approach overcomes important practical hurdles, we believe that this work reignites interest in the potential commercialization of plasmonic-based chemical sensors.
Dr. Fausto D’Apuzzo is Optical Scientist at HP Labs, working on the Life Science team. His research interests are in optics systems, plasmonics and metamaterials for bio-sensing, with a focus on Surface Enhanced Raman Spectroscopy (SERS).
