Oxidative C-H Homocoupling of Push-Pull Benzothiazoles: An Atom-Economical Route to Highly Emissive Quadrupolar Arylamine-Functionalized 2,2'-Bibenzothiazoles with Enhanced Two-Photon Absorption.

open access: yesOrganic Letters, 2021
Copper(II)-catalyzed C-H/C-H coupling of dipolar 2-H-benzothiazoles end-capped with triphenylamine moieties affords highly fluorescent 2,2'-bibenzothiazoles with quadrupolar (D-π-A-π-D) architecture displaying large two-photon absorption (TPA) cross ...

Energy separation in transient and steady-state flow across the cylinder [PDF]

open access: yesTheoretical and Applied Mechanics, 2018
Energy separation is a spontaneous energy redistribution within a fluid flow. As a consequence, there are places with higher and lower values of total temperature in the fluid flow. It is characteristic for many flow geometries. This paper deals

Scientific opinion on the exposure of children and adolescents in the Republic of Croatia to acrylamide from food

open access: yesFood Risk Assess Europe, Volume 4, Issue 1, January 2026.
Summary Acrylamide is a natural by‐product of the reaction that occurs during the baking or frying food at temperatures above 120°C in industry and in households. The main mechanism of acrylamide formation in food is the Maillard reaction, in which the free amino acid asparagine, which is found in many types of cereals and potatoes, reacts with ...
