The valorisation of lignin is being increasingly recognised to improve the economics pulp and paper making mills. In present study, an integrated lignin–glycerol strategy introduced with overarching aim for enhancing process value chains. LignoBoost kraft was subjected base-catalysed depolymerisation using glycerol as a co-solvent. generated bio-oil used renewable additive biodiesel its oxygen ...

This work is a proof-of-concept of the use azomethine-bearing diamines as novel hardeners standard epoxy compounds to yield cleavable and thermoformable covalent adaptable networks (CANs), with functional properties otherwise comparable conventional networks. A suitable aromatic diamine (TPA-o-PD) was synthesised at acceptable purity for intended successfully reacted DGEBA. The resulting cured ...

Abstract Brown rice was germinated for different times (12, 24, 36, and 48 h) at temperatures (25, 30, 35 °C) with the aim to improve in vitro digestibility antioxidant potential of flour made from it. Results showed that increase germination time temperature increased starch protein during brown owing depolymerisation molecules by enzymatic activity. After under varying conditions, activity 50...

Baobab (Adansonia digitata) fruit had received growing attention for its myriad nutritional and medicinal benefits, including those from polyphenol-rich profile powerful antioxidant activity. The current study evaluated the bioaccessibility of phenolic constituents capacity baobab pulp (BFP) byproduct, shell (BFS), upon in vitro digestion. In general, digestion reduced contents capacity; howeve...

This study investigates the long-term (570 days) performance of alkali-activated slag (AAS) mortar exposed to combined wet-dry cycles and sodium sulphate solutions (i.e. 5 wt% 10 wt%). Physical mechanical characteristics AAS mortars visual appearance, compressive/flexural strength, mass change, capillary porosity, water sorptivity) as well mineralogical chemical parameters were determined using...
