Choline chloride-based deep eutectic solvents for efficient anthocyanin recovery from black rice: process, kinetics and nanoliposomal formulation

Abstract This study investigated the recovery and nanoliposomal formulation of anthocyanin-rich extracts from black rice using choline chloride-based deep eutectic solvents (DESs). Choline chloride/1,2-propanediol (DES2) produced the highest anthocyanin content, 85.5 ± 3.4 mg l−1...

A scoping review of voice based AI chatbots in EFL learners’ meaning focused speaking in higher education

This scoping review examines the use of voice-based artificial intelligence (AI) chatbots in supporting meaning-focused speaking among English as a Foreign Language (EFL) learners in higher education (HE). In response to the rapid integration of AI technologies in HE, the study a...

pH-responsive dual-layered chitosan/Tween 80 nanoemulsions for gastrointestinal targeted delivery of curcumin

Abstract Curcumin's application is severely hindered by its hydrophobicity, poor solubility and rapid degradation. This study developed a pH-responsive, dual-layered curcumin-chitosan nanoemulsion (nCCURs) system using the phase inversion temperature method coupled with probe ult...

Enhanced FOC performance using a hysteresis current controller for EV induction motor drives

Electric vehicle traction drives require fast, robust, and efficient induction motor control, especially under variable speed, load torque, and thermal operating conditions. In Field-Oriented Control integrated Hysteresis Current Controller (FOC-HCC) induction motor drives, varia...
