  • 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.

  • 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.

    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.
