  • Magnetic tunability in tetragonal Mn--Rh--Ir--Sn inverse Heusler compounds

    Mozur, Eve; Seshadri, Ram
    Gaining control over magnetic structure has been an ongoing challenge in materials that form complex, nanoscale, non-collinear magnetic configurations. Recently, it was predicted that tuning the ratio of the Dzyaloshinskii-Moriya interaction to the uniaxial magnetic anisotropy in tetragonal inverse Heuslers through changes in composition could allow a range of interesting magnetic states to be accessed, from simple ferrimagnetism, to helical and antiskyrmionic phases. Here, we show tunability of the magnetic phase behavior in the Mn--Rh--Sn system through Ir substitution on the Rh substructure. Iridium substitution correlates to an increase in the strength of ferromagnetic exchange couplings, at the expense of antiferromagnetic exchange couplings. However, we do not observe the complex non-collinear magnetic phases proposed previously, likely due to the extremely narrow composition window where these phases are predicted to form in a bulk sample. This work highlights the sensitivity of complex magnetic structures to stoichiometry, which makes them difficult to discover empirically.
  • Prolonged dimming of Ukrainian urban illumination: a measure of conflict's impact

    Zhizhin, Mikhail; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-11-15)
    Payne Institute Earth Observation Group Researcher Mikhail Zhizhin writes about how natural disasters such as earthquakes, hurricanes or pandemics trigger a short-term dimming of city lights, followed by a rapid recovery. The war in Ukraine, however, has induced a novel pattern of city lights changes: an abrupt and sustained decline in illumination from the outset of the conflict, persisting for two years with partial recovery observed in some cities.
  • Empowering or repressive: navigating the complexities of renewable portfolio standards in the US

    Kulkarni, Siddhant; Littlefield, Anna; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-11-13)
    Payne Institute Student Researcher Siddhant Kulkarni and Program Manager Anna Littlefield write about how Renewable Portfolio Standards (RPS) represent a strategic push by governments to usher in an era of clean, renewable energy. While RPS are not the only policy-mechanisms that incentivize renewable energy, they have been in place for decades across the world. Data from the International Renewable Energy Association (IRENA) shows that worldwide installed renewable energy capacity has almost doubled in the last decade, thanks in part to the RPS policies implemented. In the US these regulations are particular to individual states and aim to combat increasing greenhouse gas emissions and by extension, climate change.
  • Supporting open science on a small budget: the role of the Mines Repository

    Kraus, Joseph; Colorado School of Mines
    The Mines Repository is a piece of the puzzle to support open science initiatives at the the Colorado School of Mines Arthur Lakes Library. Even as a small Carnegie R1 institution, the librarians provide a wide variety of open science services to Mines students and faculty.
  • Governments' recent steps to advance climate impact; select World Investment Forum highlights

    Handler, Bradley P.; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-10-25)
    Payne Institute Sustainable Finance Lab Program Manager Brad Handler writes about the 8th World Investment Forum focused on spurring sustainable development across low and middle income economies. The challenges loomed large, as speakers noted that not only were absolute spending levels far short of what was needed to be "on track" to meet energy transition and SDG targets, but that recent spending in the developing world was far too concentrated in select economies.
  • Modular carbon capture and the Inflation Reduction Act

    Littlefield, Anna; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-10-10)
    Payne Institute Program Manager Anna Littlefield writes about how as the field of carbon capture, utilization, and storage (CCUS) continues to evolve, the importance of modular carbon capture technologies has become increasingly apparent. August of 2023 marked the one-year anniversary of the Inflation Reduction Act (IRA) being signed into law, and its potential to incentivize smaller-scale capture systems is manifesting in modular capture innovation.
  • Strategy and planning to redouble climate adaptation in Africa

    Eichhorn, Julia; Flores, Daniel; Ijjasz-Vasquez, Ede; Saghir, Jamal; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-10-01)
    Payne Institute Fellow Jamil Saghir, Julia Eichhorn, Daniel Flores, and Ede Ijjasz-Vasquez write about how mounting evidence continues to show that Africa is the most vulnerable continent to the adverse impacts of climate change. Ramping up climate finance flows for adaptation is critical to addressing the irreversible impacts of climate change, but financing alone will not be enough to protect the continent. Having a clear set of priorities, with institutions that have the capacity to plan properly and take adaptation actions at scale, is equally important.
  • The state of critical minerals report 2023

    Bazilian, Morgan; Clough, Gregory; Akamboe, Juliet; Malone, Aaron; Amoah, Macdonald; Lange, Ian; Marin, Yasmin E.; Manful-Sam, Ebenezer; Handler, Bradley P.; Ayaburi, Felix; et al. (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-09-26)
    The Payne Institute for Public Policy and the Colorado School of Mines has released our inaugural annual State of Critical Minerals Report. The report is aimed at contributing to the important discourse on critical minerals and how to harness them in a more sustainable manner as a catalyst to the energy transition and by extension, climate action. It explores various parts of the critical minerals value chain and the interplay of these segments in driving a successful minerals industry. The report covers geopolitics and what that means for national security, the demand and supply dynamics of critical minerals markets, financial markets and investments, the future of sustainable mining and the environment, and social governance (ESG) factors confronting the industry.
  • The African Climate Summit – averting the climate crisis

    Akamboe, Juliet; Bazilian, Morgan; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-09-05)
    Payne Institute Research Associate Juliet Akamboe and Director Morgan Bazilian write about how climate change poses a significant threat to Africa, a continent already grappling with challenges including poverty and a lack of access to basic human needs like clean water, healthcare, education, jobs and electricity. Africa is already witnessing severe environmental consequences with changing rainfall patterns, severe droughts and extreme weather conditions, which are stalling socio-economic development.  The inaugural Africa Climate Summit (ACS) taking place in Nairobi, this week is a great forum to discuss the role Africa can play in bridging the gap between the Global North and South in addressing the climate crisis.
  • Impact of lossy compression errors on passive seismic data analyses

    Issah, Abdul Hafiz S.; Martin, Eileen R. (Colorado School of Mines. Arthur Lakes Library, 2023)
    New technologies such as low-cost nodes and distributed acoustic sensing (DAS) are making it easier to continuously collect broadband, high-density seismic monitoring data. To reduce the time to move data from the field to computing centers, reduce archival requirements, and speed up interactive data analysis and visualization, we are motivated to investigate the use of lossy compression on passive seismic array data. In particular, there is a need to not just quantify the errors in the raw data, but also the characteristics of the spectra of these errors, and the extent to which these errors propagate into results such as detectability and arrival time picks of microseismic events. We compare three types of lossy compression: sparse thresholded wavelet compression, zfp compression, and low-rank singular value decomposition compression. We apply these techniques to compare compression schemes on two publicly available datasets: an urban dark fiber DAS experiment, and a surface DAS array above a geothermal field. We find that depending on the level of compression needed, and the importance of preserving large versus small seismic events, different compression schemes are preferable.
  • Niger, uranium, and the coup d'etat

    Freeman, Baba; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-09-01)
    Payne Institute ESG Researcher Baba Freeman writes about how the recent coup d'etat in Niger, a key supplier of uranium, has created some level of anxiety in the market and brought forward new questions for stakeholders across the industry and the West African sub-region. The event calls for a fresh look at the potential market impact and the way forward to resolving the current disputation in a manner that preserves Niger's development agenda, minimizes political risk to investors, and aids the emergence of a more resilient global critical minerals supply chain.
  • Proposed West Africa-Europe gas pipelines will fail without a radical shift in thinking

    Freeman, Baba; Colorado School of Mines. Payne Institute for Public Policy (Colorado School of Mines. Arthur Lakes LibraryPayne Institute for Public Policy, 2023-08-29)
    Payne Institute ESG Researcher Baba Freeman writes about how the Russian invasion of Ukraine in 2022 injected a renewed urgency into Western European countries' energy security concerns and led to an increase in demand for non-Russian sources of oil and gas. Consequently, Europe is expected to take a larger share of future LNG supplies even as greenfield pipeline projects are being conceived to supply West African gas to Western Europe. These projects include the Trans-Sahara Gas Pipeline (TSGP) and the Nigeria-Morocco Gas Pipeline (NMGP) but may not be able to adequately meet these projects' future obligations.
