Impact of extraction methods on the determination of protein, fat, and carbohydrate content in long-life plant-based milk alternatives

Tina Nduaya Kayeye, Andrew Penton, John Ashton, Sarah Noyes et autres

Milk-alternatives manufacturers strive to produce milks that meet regulatory requirements and consumer expectations. Fat, protein and sugar content are assessed using extraction methods whose efficiency is not clear. In this study, we evaluated one physical (ultracentrifugation) and four chemical (Carrez reagent, acetic …

Tunable photoluminescence in stoichiometric tetragonal AgInS2 quantum dots: Effect of sulfur injection temperature

Sandhuli S. Hettiarachchi Dehigaspitiya, Jonghoon Han, Aarti Aarti, Long Hu et autres

Achieving high photoluminescence quantum yield (PLQY) in stoichiometric, heavy metal-free AgInS 2 quantum dots (QDs) remains a significant challenge, primarily due to the persistent formation of phase impurities during synthesis. In this study, we addressed this limitation by incorporating 1-dodecanethiol (DDT) as …
