Amino acids are important targets in the search for life beyond Earth. The types of amino acids, their relative abundances, and enantiomeric excess all serve as biosignatures. To detect such biosignatures, identification quantification individual required. Regardless analytical workflow used, it is critical to release from sample without altering molecular distributions. Subcritical water extra...

The objectives of this study were to evaluate the effects grape cultivar geographical location and extraction technique on total phenolic compounds (TPC), antioxidant capacity (AC), oil yield quality Quebranta (Vitis vinifera) seeds. Seeds defatted with supercritical CO2 bioactive extracted subcritical water macerations methanol, ethanol, acetone. differences in seed not significant (p > 0.05)....

Sweet wormwood (Artemisia annua L.) valorization is gaining importance due to the presence of health-promoting bioactive compound, artemisinin. Considering wide possible application artemisinin drug formulations, new, greener technologies in their production are welcome. In this study, was extracted from A. leaves using green extraction (ultrasound-assisted extraction, supercritical CO2 deep eu...

in drought prone environments wheat crop growth and production depends strongly on the water stored in the soil before anthesis and, although some water remains in the soil after harvest, plants experience water deficit. in order to investigate whether water ex-traction patterns, as a plant feature, have a regulating effect on the amount of water used by them at different soil depths, three whe...

A method using heated and superheated (subcritical) water is described for rapid prediction of long-term desorption rates from contaminated geosorbents. Rates of contaminant release are measured at temperatures between 75 and 150 degrees C using a dynamic water desorption technique. The subcritical desorption rate data are then modeled to calculate apparent activation energies, and these activa...
