Women in Environmental Science
Despite the prominent role that women have traditionally played in environmental activism and initiatives to promote environmental justice, women’s representation in most environmental science fields remains low. The first environmental laws in the U.S., established in the 60’s and 70’s, were propelled by movements evolved out of male dominated scientific professions, mainly engineering. To this day, environmental fields are still perceived as not open to women. Yet the field being so broad, it offers many opportunities for women scientists to contribute to the advancement of science and technology needed to address the most pressing environmental issues. To this end, the Society for Industrial Microbiology and Biotechonology organized a session at its 2019 General Meeting entitled Women in Environmental Science that showcased the work of women leading efforts in environmental fields. The session was convened by Dr. Gemma Reguera (Michigan State University) and Dr. Arpita Bose (Washington University in St. Louis) and included 4 additional speakers whose work spans basic and applied environmental research yet impacts discovery-driven science, technology development, science policy and communication, in addition to environmental advocacy and stewardship. The talks highlighted the career path of women-led teams whose research and professional activities are contributing to the development of “biobased solutions to DOE mission challenges in energy and environment”.

Q and A with the grandson of the Little Boy’s pilot: Brigadier General (retired) Paul Tibbets IV reflects on his family’s legacy military service
Paul Tibbets Jr., the pilot of the Enola Gay who released the Little Boy atomic bomb above Hiroshima, is part of a family with a legacy of military service. He was father to Paul Tibbets III, who served in the military as an Army reservist pharmacist and hospital administrator and eventually retired as a colonel. His son— grandson of Tibbets Jr.—is also Paul Tibbets. Paul Tibbets IV is a retired Air Force brigadier general and decorated bomber pilot. This legacy is not lost on his fellow airmen. They gave Tibbets IV the callsign “Nuke” early in his flying career. Tibbets IV flew the B-1 bomber and then the B-2 stealth bomber, a nuclear-capable, longrange strike aircraft. His 29 years of military service include combat missions in the Middle East, Afghanistan, and the Balkans—and a flight in a restored B-29 with his grandfather. In commemoration of the 75th anniversary of the atomic bombs and his grandfather’s historic role, Tibbets IV spoke with Los Alamos National Laboratory.

Strategies for seeking a job at a national lab [Slides]
Understanding the job market from the hiring side can help you develop better strategies for seeking a job. National laboratories represent a substantial source of jobs in the U.S. in engineering and science. High school, college, and graduate student internship positions are all available, but you can be more successful in finding one of these positions if you use a targeted search. Likewise, reaching out to individual researchers and/or knowing how to respond to job ads can increase your chances of getting an interview for a permanent job or positions, such as postdoc and postbac appointments, that can lead to permanent jobs. In my career as a research scientist at Los Alamos National Laboratory, I have hired people into all of these job categories, as well as served on many hiring committees for all levels of appointments. I will offer Polonius*-type advice for jobseekers and discuss the hiring process and how you can optimize your own job search.

Probing Coherent States of Light and Matter in Two-Dimensional Semiconductors. Final Report
The ability to enhance light-matter interactions in engineered optical environments is well-established in micro- and nano-photonics. New classes of materials bring new rich correlations between spin, momentum, and light polarization that can be exploited in these photonic systems for information processing and low-power electronics. Interfacing these novel material features with strong optical interactions suggests the compelling capability to create hybrid light-matter systems harnessing low-energy and protected material properties such as spin. The long-term objective of this program was to investigate the interplay between pseudospin in 2D materials and light, revealing new coherent phenomena. The materials studied are the monolayer transition metal dichalcogenides (TMDs), which support polarization-sensitive optical transitions when isolated to a single sub-nanometer crystal layer in thickness. In particular, monolayer TMD semiconductors such as MoS 2 exhibit degenerate valleys in momentum space with distinct spin character. These valleys can be separately addressed by circularly polarized light, providing a tool for manipulation. Integrating this valley pseudospin of excitons in monolayer TMDs with engineered strong optical excitations to create novel coherent phenomena was a key long-term goal of this research. The scope of this research primarily focused on studying light-matter interactions of valley-sensitive excitations in monolayer TMDs. The scope also included the integration of monolayer materials that support valley-polarized emission into photonic devices. This approach extends prior work on exciton-polaritons in 2D materials toward a platform with far more control and improved light input and output characteristics to aid scalability of these polarization-sensitive phenomena to many-body, long-range optical networks. During the course of the five-year Early Career program, the approaches led to successful progress on each proposed aim. Initial successful work seeded additional research that developed from the main themes, while this program focus evolved toward coherent manipulation of valley polaritons and integration with photonics. Both of these advanced topics set the stage for new capabilities in future innovative research. The results of this project provide advances in materials and methods relevant for new visions of opto-electronics and photonics that can improve information processing in an era of increased focus on quantum and coherent phenomena. The research has also contributed to the training of two postdoctoral scholars and five graduate students.

MST e-News (Fall 2020)
As we just closed the fiscal year, I have been reflecting on the state of the division, and in particular, the health of our budget, staffing plans, and infrastructure. As many of you know, the division has grown in both budget and workforce. Since 2018, the division has grown from 150 to 174 permanent staff (but note, with students, post docs, and contractors—we are a division of 218). As one might imagine, our budget has grown significantly too. In 2018, at year end, we had a budget of $85 million. While I am still collecting some final numbers, all projections indicate that we closed out FY20 at $115 million. This growth has occurred primarily in our applied energy programs as well as Pu Sustainment. However, it is important to note that there have been important contributions to this growth across much of the portfolio, including in our OES, BES, and LDRD programs. With that said, to support this programmatic growth, as a division we have done a tremendous amount of hiring to grow while outpacing attrition. At the same time, we have been establishing numerous new capabilities at TAs -3, -35, and -55. While this is exciting, it means we have some things to carefully consider. We have had numerous capability investments (i.e., new microscopes at TAs -3 and -55, new mechanical testing capabilities at TAs -3 and -35, and new synthesis capabilities across the division). But we are starting to feel the real crunch of the limitations of our aging facilities. Still more, even with this substantial growth, we continue to hire. And I believe that we really need to spend time thinking about mentoring, career development, and retention of our most important investment—our staff.

2019 Quantum Materials Young Investigators Workshop Report
The fourth edition of the workshop “Quantum Materials Young Investigators” was held June 6-7, 2019 at the Oak Ridge National Laboratory (ORNL). This workshop followed up on previous meetings that took place at ORNL starting in 2016. This important series of annual workshops, organized by Adam Aczel and Stuart Calder, ensures continuous engagement with the early career principal investigators (PIs) of the quantum materials neutron scattering community. Through a series of short scientific talks presented by the external PIs, members of the Neutron Scattering Division (NSD) learn about their scientific interests and needs. Presentations from ORNL staff members also help to inform the external PIs about the current state of ORNL’s quantum materials neutron scattering program. Topics covered include the current instrument suites, sample environment, data reduction, visualization, and analysis, and future neutron scattering and complementary capabilities. Feedback is solicited from the external PIs in all these key areas and communicated to NSD management in the form of a workshop report. This workshop series also helps to foster collaborations between NSD scientists and the research groups of the external PIs and plays an important role in attracting new neutron scattering users.

Adaptive complex nanocomposite alloys for burning plasma-material interface tunability (Final Report)
The focus of this program is discovery and development of novel self-healing and adaptive materials for the PMI (plasma-material interface) envisioned for future plasma-burning extreme environments in thermonuclear fusion reactors that can provide enhanced radiation-tolerance or resistance. This program was conceived and stems from the PI’s DOE Early Career Award work on harnessing nanotechnology and mesoscale materials design in refractory metals to address gaps in PMI research. These gaps pertain to the lack of understanding of multi-scale interactions at the plasma-material interface and the development of novel material interfaces that can be designed to adapt to extreme fusion reactor conditions. The final report is separated into two primary sections: The first section consists of the program’s first two years (FY16-FY17) performance period. The second section consists of FY18 to FY19 period, where the FY19 period was a supplemental addition to support the completion of a PhD thesis and continuation of another. This work consists of an excellent team consisting of a co-PI, one postdoctoral researcher, two graduate students, two undergraduate students and collaborators both domestic and abroad.

The Wonders of Physics -- Public Outreach (Final Technical Report)
The mission of The Wonders of Physics (TWoP) outreach program is to generate interest in physics among people of all ages and backgrounds. The objective is to generate interest in physics, increase appreciation for the significance of physics in our lives, and encourage children to consider careers in science and plasma physics. The primary means for achieving that objective is to make entertaining presentations to audiences that would not normally be motivated to attend a lecture on physics or plasmas, while at the same time introducing some of the fundamental concepts and applications. During this reporting period, the students Michael Hall, Megan Tabbutt and Connor Sullivan, Director of Communications Sarah Perdue, Director of Undergraduate Program Jim Reardon, and Senior Information Processing Consultant Paul Wilhite worked to make outreach programs a success and prepare for the future of The Wonders of Physics, which will continue. Because of the curtailment of public events due to Covid-19, there will not be an in person Annual Show or Physics Fair in 2021, but a video competition has already been announced and planning continues for The Wonders of Physics in 2022 and beyond. The annual shows and Physics Fair are scheduled for February 12-13 and February 19-20, 2022. These continue to be our premier outreach events, engaging diverse audiences in real hands-on science. Further shows and exploration stations are planned.
