Total lipids from serum were extracted using hexane:ethanol (1 1) solvent mix by mixing equal volumes of the serum and the solvent mix, vortexing for 10 min and centrifuging at 2,095 g for 10 min at room temperature.
However, with 30% of TEA and 20% solvent mix maximum scrubbing factor (E) of 0.63 mol-CO2/mol-Solvent was achieved.
By contrast, our newly designed solvent mix composed of butanol, methanol and chloroform (at a 3 5 4 ratio) provided similar extraction efficiency for triglycerides and higher yield for some of the phospholipids, as compared to the Folch method.
A central composite design was applied in order to establish the optimal extraction conditions: the solid-liquid extraction was done under sonication using 500 μL of a solvent mix 70/30 acetonitrile/ethyl acetate and an extraction time of 17 min at 39 °C.
The clean-up performed on solutions of PDIMs and cholesterol standards in petroleum ether show that, depending on the solvent mix and on the type of SPE used, the recovery of PDIMs is between 64 and 70%, whilst most of the cholesterol is removed from the system.
By studying the mixed solution of dimethylsulfoxide (DMSO) and water at varied DMSO/H2O ratios, it was found that deviation from the general water-phase fructose yield curve, with concomitant 5-hydroxymethylfurfral (HMF) formation, occurred when the fructose concentration in available water became sufficiently high in DMSO rich solvent mix.

These investigations show that LDPE/MWCNT composites can be fabricated using simple solvent mixing method.
The binary co-solvent system studied included water as the primary solvent mixed with an organic co-solvent, e.g., ethanol.
Nano-composites of LDPE and MWCNT are generally prepared by using the melt blending method but in the present investigation these have been prepared by using solvent mixing method.
