Summary: The prospective assessment of environmental and economic costs of emergent technologies based on biomass feedstocks is important for guiding academic research and corporate investments. This study evaluates a new pathway for producing N-vinyl-2-pyrrolidone from succinic acid, showing that bio-based production can reduce global warming impacts by 25-53% compared to fossil alternatives. However, the reductions in global warming impacts should be weighed against increasing eutrophication and acidification.

Summary: A Castor oil/PVP hybrid was synthesized and emulsified in water to obtain a stable white emulsion with particle size ranging from 320 to 370 nm. This emulsion was used for functional finishing of cotton fabric, resulting in improved nitrogen content, tensile strength, whiteness index, stiffness, and antibacterial activities. Incorporating zinc oxide nanoparticles or dihydroxybenzophenone further enhanced the functional properties. Dyeing and finishing of fabric samples also improved color strength, but only direct dye dyed/finished samples showed improved fastness to washing and perspiration.

Summary: Cellulose nanofibers (CNFs) were used to improve the performance of poly (acrylic acid-co-N-vinyl pyrrolidone) hydrogel as a forward osmosis (FO) draw agent. The successful incorporation of CNFs was confirmed by various analyses. The results showed that the addition of CNFs increased the swelling ratio and water flux of the hydrogel, but a higher CNF concentration led to a slight decrease in water flux. Furthermore, the CNF-based hydrogel exhibited acceptable recycling capability in five consecutive FO cycles and was able to efficiently treat Direct Red-80 dye.
