Chemical characterization of the adhesive secretions of the salamander Plethodon shermani (Caudata, Plethodontidae)

open access: yesScientific Reports, 2017
Salamanders have developed a wide variety of antipredator mechanisms, including tail autotomy, colour patterns, and noxious skin secretions. As an addition to these tactics, the red-legged salamander (Plethodon shermani) uses adhesive secretions as part ...

Ab Initio Dot Structures Beyond the Lewis Picture

open access: yesMolecules, 2021
The empirical Lewis picture of the chemical bond dominates the view chemists have of molecules, of their stability and reactivity. Within the mathematical framework of quantum mechanics, all this chemical information is hidden in the many-particle wave ...
