The number serves as a specific identifier across several highly technical scientific research papers and modern engineering databases. While it may appear as a simple sequence of digits, it is most notably a reference code used in physics and environmental chemistry to catalog breakthrough studies. 1. Semiconductor Physics and Energy Research
: A recent 2026 study in Carbohydrate Polymers uses this number to catalog research on polysaccharide-based adsorbents . These materials are designed to trap PFAS (harmful chemicals found in many household items) using natural substances like cellulose and chitosan.
), which is vital for high-power electronics and heat dissipation. 2. Environmental Engineering and Sustainability 125209
: Another major study identified by this number focuses on AgGaTe2 , a material used to convert heat into electricity. The research details how a mixture of "light" and "heavy" energy bands allows these materials to be highly efficient for thermoelectric applications .
: One of the most cited works under this number, published by researchers like Chris Van de Walle , explores the energy levels of hydrogen in silicon. This is critical for improving device reliability in modern electronics, as hydrogen significantly affects how impurities behave within computer chips. The number serves as a specific identifier across
: It also references work on microbial electrolysis cells that use external voltage to recover hydrogen and other useful minerals from fermentation liquids, contributing to more sustainable waste management. 3. Specialized Applications
: Within NASA and Wikimedia archives, ISS030-E-125209 is a specific photo ID for a high-altitude view of Earth taken from the International Space Station at an altitude of approximately 406 km. Semiconductor Physics and Energy Research : A recent
In the field of semiconductor physics, "125209" is a recurring article identifier in the prestigious journal Physical Review B .
