Plasticizer enhancement on the miscibility and thermomechanical properties of polylactic acid-chitin-starch composites
(
MDPI AG
, 2020 , Article)
In previous research, a polylactic chitin starch composite was prepared without the use of a solvent to enhance the miscibility. In this study, a polylactic acid (PLA) chitin starch composite was produced with chloroform ...
Impact of ambient temperature, precipitation and seven years of experimental warming and nutrient
(
Elsevier
, 2021 , Article)
Global change is causing changes in temperature, precipitation, and nutrient availability. Alpine and polar regions are predicted to be among the most vulnerable for these changes. We applied a seven-year factorial experiment ...

A robust field-based method to screen heat tolerance in wheat
(
Elsevier
, 2023 , Article)
Wheat is highly sensitive to heat shocks and their timing. Hence, field-based ranking for heat tolerance may be confounded by phenological variations at the time of heat events. A photoperiod-extension method (PEM) was ...
