“…This could be explained by the addition of mesopore originating from Fe 3 O 4 nanoparticles which indicated by the appearance of a new broad peak above 5 nm in MPC pore size distribution as found in inserted graph in Figure 4(a–c). The D pore slightly decreased ( D pore of MPC−NH 2 = 3.69, V pore = 12.74 × 10 −2 cm 3 /g) after silylation which is relevant to previous publication due to pore blocking effect of poly‐siloxane network condensed in the surface of materials 30,49,57 …”

“…The procedure of cellulose extraction followed our previous report with slight modification. 30,49 Briefly, 20 g of OPEFB was first alkalized using sodium hydroxide (17% wt/vol) at room temperature for 24 h and was repeated three times. Afterward, the alkalized OPEFB was washed using distilled water until reaching neutral pH.…”

The reaction under ultrasonic irradiation was performed for 1 h and then continued stirring at 500 rpm for 20 h. The silylated-MPC (MPCÀNH 2 ) particles were washed several times using distilled water and dried under a vacuum.…”

Loading of quercetin onto drug cargo is still progressively studied to not only improve its solubility but also control the release behavior for improving therapeutics efficacy. In this present study, we successfully prepared drug cargo based magnetically porous cellulose (PC) functionalized by amine‐based alkoxysilane (MPC−NH2) for effectively carrying and sustainably delivering quercetin. The PC derived from oil palm empty fruit bunches provides high loading capacity reaching 344.48 ± 5.69 mg/g with loading effectiveness of 67.02 ± 1.11%. Surface modification of PC surfaces by Fe3O4 nanoparticles and aminosilane compounds not only enhances the quercetin loading effectiveness to 80.83 ± 1.10% but also controls the quercetin release behavior either at artificial gastric or physiological condition. The kinetic release study elaborates that anomalous transport is mainly involved during release of quercetin under physiological condition, but the Fickian diffusion plays the role at artificial gastric condition. The kinetic release rate of quercetin calculated following Higuchi model indicates that the Que@MPC−NH2 has slower release rate compared to another drug carrier. Additionally, the antioxidant activity of quercetin is significantly improved after being loaded onto MPC−NH2. Finally, we recapitulate that the loading of quercetin within MPC−NH2 is a powerful strategy for improving loading capacity, drug‐release ability, and antioxidant activity.

The development of membrane technology is rapidly advancing, such as hydrophilic PVDF membranes, which provide anti‐fouling properties to the membrane. Therefore, this research innovates the development of hydrophilic PVDF membranes by incorporating lignin‐lignosulfonate fillers from OPEFBs in situ. This study successfully prepared hybrid PVDF membranes using the phase inversion method. ATR‐FTIR, XRD, and TGA/DSC analyses confirmed that the addition of 2 % filler promoted the formation of the β‐phase in PVDF, which was more dominant than with the addition of 4 % filler, especially in the PLs2 % membrane. SEM images of the membranes showed an asymmetric structure with finger‐like and sponge‐like pores. Interactive 3D surface imaging demonstrated increased pore potential peaks when lignosulfonate was added compared to lignin. The addition of 4 % filler had a hydrophilic‐hydrophobic repelling effect, increasing the porosity and water absorption of the PL4 % and PLs4 % membranes. Phase inversion membranes were relatively hydrophilic with a water contact angle of 61°, and adding filler reduced the membrane‘s contact angle by 8°. Based on the obtained results, it can be concluded that PVDF hybrid membranes with lignin and lignosulfonate fillers have significant potential for development in membrane technology applications that require hydrophilic membranes, such as wastewater treatment and seawater desalination.
