A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Ultrasonic‐assisted extraction of bioactive compounds from eggplant (Solanum melongena L.) calyx and evaluation of extract properties

JSFA reports, EarlyView.
Abstract Background Eggplant (Solanum melongena L.) is widely consumed worldwide and generates considerable waste, including peel and calyx, during processing and consumption. Although often considered as by‐products, these wastes are rich sources of bioactive compounds, which vary depending on the plant variety and cultivation location.
