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 ...

Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

High Voltage, Volume 11, Issue 2, Page 385-398, April 2026.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

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 ...

Insight Into the Failure Mechanism of Conversion‐Alloy Anode Materials in Potassium‐Ion Batteries: A Case Study of Bi2Te3

Carbon Energy, Volume 8, Issue 2, February 2026.
Through combining electrochemical profiles with multi‐scale microscopies, spectroscopy, and theoretical calculations, the failure processes and mechanisms of Bi2Te3 are identified into two stages: (1) the shuttle effect, dominating the first stage, results in the rapid capacity fading in the first several cycles and (2) the SEI accumulation, dominating
