Adsorption mechanism and valency of catechol-functionalized hyperbranched polyglycerols [PDF]

open access: yes, 2015
Nature often serves as a model system for developing new adhesives. In aqueous environments, mussel-inspired adhesives are promising candidates. Understanding the mechanism of the extraordinarily strong adhesive bonds of the catechol group will likely ...

A facile molecularly imprinted polymer-based fluorometric assay for detection of histamine [PDF]

open access: yes, 2018
Histamine is a biogenic amine naturally present in many body cells. It is also a contaminant that is mostly found in spoiled food. The consumption of foods containing high levels of histamine may lead to an allergy-like food poisoning. Analytical methods

Poly(trimethylolpropane trimethacrylate) modified with esters derivatives of 3-phenylprop-2-en-1-ol [PDF]

open access: yesJournal of Thermal Analysis and Calorimetry, 2018
The main objective of this paper was to study the influence of the diesters derivatives of naturally occurring alcohol: 3-phenylprop-2-en-1-ol, on the thermal, viscoelastic and mechanical properties of bulk poly(trimethylolpropane trimethacrylate) [poly(TRIM)]. The bulk poly(TRIM) networks were obtained by mixing trimethylolpropane trimethacrylate with
