Branched polyethylene imine (BPEI, MW 25 000), alginic acid, anhydrous ethanol, and methanol were purchased from Aldrich. Based on the information of FMC Corporation, we supposed the molecular weight of alginic acid to be 75 000 based on the viscosity of 15–25 cps in 1% of H2O (Pronova UP VLVM, viscosity: <20 mPa, Ms < 75 kDa). A non-oxidized silicon wafer was obtained from Namkang Hitech Co., Ltd (Korea). The electrode of a quartz crystal microbalance (QCM) was obtained from Stanford Research Systems (SRS).

The following materials
were used for the production of conventional alkyl esters: refined
grapeseed oil, donated by Movialsa S.A.; absolute ethanol and Methanol
(both from Panreac Applichem); sodium ethoxide (21% w/w in ethanol)
and sodium methoxide (30% w/w in Methanol) (both from Acros Organics);
sodium chloride (supplied by Glass Chemicals); and a 4 Å molecular
sieve (pearl-shaped 2–3 mm; Scharlau).
Grapeseed used
in the in situ transesterification and in the antioxidant extraction
was the same as that used in the previous work.8 (link) Methanol (Panreac Applichem) and hydrochloric acid (AnalaR
NORMAPUR) were also used in these processes. Defatted grapeseed flour
was donated by Alvinesa S.A.
For the experimental measurement
of oxidation stability, acetone
(Kelsia), distilled water (Bosque Verde), and isopropanol (Panreac
Applichem) were used. In addition, butylhydroxytoluene (BHT; SAFC)
was used as an additive to improve the oxidation stability of conventional
biofuels.
For the evaluation of the natural antioxidant content
by UV–vis
spectroscopy, the following materials were used: tetrachloroethylene
(Uvasol), purchased from Merck; and the double beam UV–vis
instrument, which was a Specord 200 Pins of Analytikjena (Germany)
with 1 cm quartz cuvettes, controlled by the software WinASPECT PLUS
v4.2.0.0.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
