), which is vital for high-power electronics and heat dissipation. 2. Environmental Engineering and Sustainability

The number also appears in niche technical and logistical contexts:

: 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.
