AtomiQ, Nuclear Diamond Batteries' Subsidiary, Signs MOU With Curio on Strontium-90 and Americium-241 Supply

AtomiQ, Inc., the majority-owned subsidiary of Nuclear Diamond Batteries, Inc., signed a Memorandum of Understanding with Curio Legacy Ventures, Inc. on November 12, 2026 to explore technical collaboration and potential future supply of strontium-90 and americium-241 for nuclear battery development. GlobeNewswire published the announcement.

AtomiQ and Curio's Isotope Supply Framework

The MOU sets a framework for the companies to explore technical collaboration and potential future supply of strontium-90 (Sr-90) and americium-241 (Am-241), two radioisotopes with potential applications in long-duration power technologies. Curio, a Washington, D.C.-based nuclear technology company, is developing its patented NuCycle process to recover valuable materials, including radioisotopes, from used nuclear fuel. The companies intend to evaluate how Curio's isotope recovery capabilities could support AtomiQ's development of diamond and carbon-based nuclear-voltaic power sources.

The collaboration will initially focus on assessing technical feasibility, isotope characteristics, potential supply requirements and the regulatory considerations associated with future commercial applications. Key areas include a potential domestic supply pathway for Sr-90 and Am-241, isotope specifications and characterization requirements, licensing and material handling, and potential government, research and commercial applications. The MOU does not establish committed purchases, supply volumes, delivery schedules or a contract value, and any future supply would be subject to separate agreements, technical validation, regulatory authorizations and facility readiness.

"Reliable access to appropriately characterized radioisotopes is an important part of advancing our nuclear battery technology, and domestic sources of strontium-90 and americium-241 have historically been limited," said Dr. Greg Rubin, Chief Executive Officer of AtomiQ. "This agreement gives us a structured path to qualify material, align technical requirements and plan supply as our development program progresses, and it addresses the full life cycle of the material, from delivery to take-back."

Edward McGinnis, President and Chief Executive Officer of Curio, said: "Our collaboration with AtomiQ highlights the growing commercial opportunities for recovered isotopes and the importance of establishing a reliable domestic supply chain."

AtomiQ's Earlier Isotope and Patent Moves

According to akta.pro company records, AtomiQ entered a collaboration agreement with Nusano, a radioisotope production company, in February 2025 to jointly develop and advance nuclear diamond battery technologies and infrastructure. The same records show that the USPTO issued patent US12394534B2 in March 2025 covering a diamond-based nuclear voltaic power source that converts radioisotope radiation into electric power. In July 2026, AtomiQ received three Notices of Allowance from the USPTO covering diamond-based nuclear voltaic power conversion, MOF electrodes with carbon nano-onion structures, and methods for synthesizing carbon nano-onions.

Nuclear Diamond Batteries' Recent Announcements

AtomiQ plans to attend the 2026 NASA Aerospace Battery Workshop in Huntsville, Alabama, Nuclear Diamond Batteries said on November 11, 2026, according to GlobeNewswire. On September 30, 2026, the company published a white paper proposing nuclear diamond batteries for LoRaWAN sensors, targeting a 150-million-device ecosystem, Stock Titan reported. In July 2026, Nuclear Diamond Batteries summarized its expanding U.S. patent portfolio and near-term intellectual property strategy for its nuclear diamond battery platform, FinancialContent Business Page reported.
