Migration of chemicals from plastic containers into drinks and liquids containing them, is supposed to be a hazardous phenomenon and results in many health problems. Sample preparation is of great importance due to trace amounts analysis of these compounds. In this research, dispersive liquid–liquid microextraction is applied for the extraction and preconcentration of the migrated compounds pri...

Microdera punctipennis Kasz (Coleoptera: Tenebrionidae) is a unique species that lives in the desert region of Central Asia and has adopted a nocturnal habit to survive the desert environment. Female adults are larger in size than male adults. The female/male ratio was 1.04:1. A rearing method using reused plastic bottles was used. The rearing conditions were 30 ± 0.5 °C, 30 ± 6% relative humid...

Captopril is an angiotensin-converting enzyme inhibitor available as a tablet. Patients who are unable to take tablets have led compounding pharmacies to seek alternative dosage forms including solutions and suspensions. The objective of this study was to determine the stability of captopril in sorbitol-free, alcohol-free SyrSpend SF suspending agent. The studied samples were compounded into a ...

The key-objective of this opinion paper is to highlight how and why (enzymatic) reactive extrusion, i.e., REx, expected reduce the plastic pollution particularly in oceans. As green (solvent-free) continuous innovative process, REx represents such an efficient tunable industrial tool either for producing biodegradable biosourced plastics, so called bioplastics, or enzymatically recycling bottle...
