Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Microwave and microwave-vacuum drying as alternatives to convective drying in barley malt processing

Innovative Food Science and Emerging Technologies, 2021
Abstract Barley malt is widely used in food and beverage industries. Although microwave drying can be an interesting alternative for stabilization, it has been traditionally processed by convective drying. This work studied the microwave and microwave-vacuum drying of barley malt, evaluating hydration, germination and drying.

Comparison of drying characteristic and uniformity of banana cubes dried by pulse‐spouted microwave vacuum drying, freeze drying and microwave freeze drying

Journal of the Science of Food and Agriculture, 2014
AbstractBACKGROUNDTo overcome the flaws of high energy consumption of freeze drying (FD) and the non‐uniform drying of microwave freeze drying (MFD), pulse‐spouted microwave vacuum drying (PSMVD) was developed.RESULTSThe results showed that the drying time can be dramatically shortened if microwave was used as the heating source.
