Physicochemical and Thermal Evaluation of a Mixed‐Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.)

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Processing–Property Mapping of Flash‐Sintered Wall Tile Bodies

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT This study investigates the effects of furnace temperature (900°C and 945°C), applied electric field (50–200 V.cm−1), and current density (50–150 mA.mm−2) on the physical properties and microstructure of flash‐sintered wall tile bodies. Water absorption, bulk density, and open porosity were measured and compared with an industrially fired ...
