Calixarene-based langmuir monolayers : from crystallization templates to metal organic networks [PDF]

open access: yes, 2015
Molecular self-assembly plays a pivotal role in biological processes and living organisms can be considered as the result of the self-assembly of discrete molecular building blocks into sophisticated functional structures.

Fast negative breakdown in thunderstorms

open access: yesNature Communications, 2019
Recent studies have shown that lightning is initiated by a newly-recognized discharge process called fast positive breakdown. Here, the authors present observational evidence of fast breakdown but of negative polarity, seemingly contrary to current ...

Protein Adsorbate Biohybrids and Sequential Hystallosteric Protein Adsorption

open access: yesCurrent Directions in Biomedical Engineering, 2021
Protein adsorption on solid surfaces is characterized by multivalence, binding-unit overlap, sequential adsorption, surface allosterics, lateral interactions and pronounced adsorption-desorption hysteresis, giving rise to the sequential, hystallosteric ...

Planktonic communities and chaotic advection in dynamical models of Langmuir circulation [PDF]

open access: yes, 1998
A deterministic mechanism for the production of plankton patches within a typical medium scale oceanic structure is proposed and investigated. By direct numerical simulation of a simple model of Langmuir circulation we quantify the effects of unsteady ...
