Fossil-based polymers dominate the packaging industry thanks to their performance and low cost. However, negative impact on our biosphere demands a paradigm shift in industry. Nature may provide an alternative form of suberin. Suberin is amorphous polyester present plants where it contributes controlling water gas exchange with environment. The bark rich suberin represents large by-product forestry industry, hence, potential source renewable monomers for synthesis materials. In this study,...
The present study explores the osmotic energy potentials of deep eutectic solvents as an efficient and sustainable alternative source for protein DNA enrichment using forward osmosis (FO).
Abstract Polyvinylidene fluoride (PVDF) and polyacrylonitrile (PAN) ultrafiltration (UF) membranes are widely used in drinking water wastewater applications. These prone to fouling membrane efficiency decreases with time under constant operation. Significant improvements/modifications necessary apply these polymers as sustainable materials. In this study, PVDF PAN UF were modified through incorporation of nanoparticles (NPs) namely SiO 2 TiO . prepared by phase inversion method from polymer...
Microemulsions (MEs) comprising choline dioctylsulfosuccinate [Cho][AOT], a biobased ionic liquid (IL) surfactant as an emulsifier, (R)-(+)-limonene (RL) nonpolar phase, and ethylene glycol (EG)/ethanolammonium formate (EOAF) organic solvent/low-viscosity IL polar component were constructed. Spontaneous aggregation of [Cho][AOT] was observed with negative ΔH form using isothermal titration calorimetry.
