High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

open access: yesAngewandte Chemie, EarlyView.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...

Development and Evaluation of a Colourimetric LAMP Assay for Field Detection of Erysipelothrix rhusiopathiae in Poultry Using a Rapid DNA Extraction Method. [PDF]

open access: yesVet Med Sci
This study presents a colourimetric LAMP assay combined with a rapid DNA extraction method for the field detection of Erysipelothrix rhusiopathiae in poultry. The workflow provides rapid and reliable diagnosis without specialised laboratory equipment, supporting on‐farm disease surveillance and outbreak management.

Petrology and dating of the Permian lamprophyres from the Malá Fatra Mts. (Western Carpathians, Slovakia)

open access: yesGeologica Carpathica, 2018
Calc–alkaline lamprophyres are known from several localities in the Malá Fatra Mountains. They form dykes (0.5–3 m) of varying degree of alteration that have intruded the surrounding granitoid rocks which are often incorporated xenoliths. Clinopyroxenes (

Evolution of the volcanic mechanism in the central part of the Urumieh-Dokhtar magmatic arc

open access: yesJournal of Economic Geology, 2021
Introduction Cenozoic volcanic activities in the Urumieh-Dokhtar Magmatic Arc (UDMA) have occurred in three main pulses of Eocene, upper Oligocene-Pliocene, and Pio-Quaternary (Dilek et al., 2010, Sayari, 2015).

Tracing the evolution of calc-alkaline magmas: in-situ Sm-Nd isotope studies of accessory minerals in the Bergell Igneous Complex, Italy [PDF]

open access: yes, 2009
The common occurrence of Ca- and Nd-rich accessory minerals titanite, epidote, allanite and apatite in calc-alkaline plutonic suites makes them ideal targets for in-situ tracing of the temporal, chemical and isotopic evolution of tonalitic and ...
