Temperature-independent non-linear terahertz transmission by liquid water

Autor: Célia Millon, Johannes Schmidt, Sashary Ramos, Eliane P. van Dam, Adrian Buchmann, Clara Saraceno, Fabio Novelli

Publikováno v: AIP Advances, Vol 12, Iss 11, Pp 115319-115319-5 (2022)

Liquid water is one of the most studied substances, yet many of its properties are difficult to rationalize. The uniqueness of water is rooted in the dynamic network of hydrogen-bonded molecules with relaxation time constants of about one picosecond.

Aqueous hyaluronan solutions form an elastic hydrogel within a narrow pH range, around pH 2.4, making this a model system to study the conformational changes of the hydrogen bond network upon gelation. This pH-dependent behavior allows us to probe wa

It is generally accepted that the hydroxide ion (OH–) is a strong hydrogen bond acceptor and that its anomalously high diffusion constant in water results from a Grotthuss-like structural diffusion mechanism. However, the spatial extent over which

Polyisocyanotripeptides (TriPIC) are biomimetic polymers which consist of a β-helical backbone stabilized by hydrogen bonds between amide groups. Their oligoethylene glycol side chains give aqueous TriPIC solutions a thermoresponsive behavior: at 50
