Optimisation of Microwave‐Assisted Extraction and Spray Drying for Chlorophyll Powder Production From Ceratophyllum submersum L.

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
An integrated microwave‐assisted extraction (MAE) and spray‐drying process was developed and optimized by response surface methodology (RSM) to produce a stable chlorophyll powder from the underutilized aquatic macrophyte Ceratophyllum submersum L. The resulting powder combined high pigment retention (67.81% chlorophyll; 63.74% recovery) with favorable

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...
