Advanced Functional Materials, EarlyView.Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

P-51 An Involute and Evolute of a Rectifying Curve
, 2019 The idea of involute is due to C. Huygens (1658), and he is also known for his work in optics. He found involutes while trying to build a more accurate clock. Now, the involute and evolute are well-known concepts to study space curves in 3D space.
