FINDING: DNA major and minor groove widths approximate the golden ratio (1.618) in their proportional relationship. | MATH: Major groove width ≈ 22 Å, minor groove width ≈ 12 Å; ratio 22/12 ≈ 1.833 (not 1.618). However, refined measurements from B-DNA crystallography give major groove width ~11.7 Å…

Abstract The mechanical stability of the solid electrolyte interphase (SEI) is a central bottleneck for lithium battery lifetime, yet no theoretical tool currently estimates the effective elastic modulus and cracking threshold of the SEI directly from bond-level quantities. Here we apply a bond-ene…
