“…The curves of the PES and PES- g -PEG membranes showed a broad scattering peak located at approximately 20°, which might be due to the convolution of amorphous and crystalline scatterings . The peaks at 16.08 and 22.43° for the PES- g -PEG/PDA membrane increased significantly, which could be attributed to the intermolecular interactions between the functional groups and the amorphous structure of PDA . However, these diffraction peaks decreased dramatically when Lyz was immobilized on the surface of the PES- g -PEG/PDA membrane, which was attributed to the amorphous structure of Lyz, weakening the inter- and intramolecular interactions of PDA. , …”

Endotoxin adsorption has received extensive attention in the field of blood purification. However, developing highly efficient endotoxin adsorbents with excellent hemocompatibility remains challenging. In this study, we propose a new approach for developing the functional polyethersulfone (PES) membrane to remove endotoxins. First, the PES polymer is grafted with polyethylene glycol methyl acrylate (PEG-MA) in a homogeneous phase system via γ irradiation, and PES-g-PEG can be directly used to prepare the membrane by the phase inversion method. Then, polydopamine (PDA) is coated as an adhesive layer onto a PES-g-PEG membrane in an alkaline aqueous solution, and lysozyme (Lyz) is covalently immobilized with PDA through the Schiff base reaction. Lysozyme acts as an affinity adsorption ligand of endotoxin through charge and hydrophobic action. Our study reveals that the PEG branched chain and the PDA coating on the PES membrane can maintain the secondary structure of lysozyme, and thus, the immobilized Lyz can maintain high activity. The adsorption capacity of endotoxins for the PES-g-PEG/PDA/Lyz membrane is 1.28 EU/mg, with an equilibrium adsorption time of 6 h. Therefore, the PES-g-PEG/PDA/Lyz membrane shows great potential application in the treatment of endotoxemia.

Bio-derived activated porous carbon is readily used because it exhibits high surface area, excellent electrical conductivity, high stability, environment-friendly nature, and easy availability. All of these properties make it a unique and a perfect applicant for energy storage devices. Biowastes such as corncobs, walnut shells, human hair, jute, oil seeds, and bamboo are utilized as precursors in manufacturing porous carbon. The use of bio materials is preferred because of their abundance and biodegradable nature. The production of porous carbon was carried out through pyrolysis with the help of acid, primarily KOH, as the active substance. The ambient temperature for conducting pyrolysis is 400-800oC. Pyrolysis can be either fast or slow, with fast pyrolysis being helpful in most experiments. Food wastes like peels and shells are among the most significant biowaste sources alongside farm waste like rice husks, coconut shells, etc., which are not just waste and can be utilized for sustainable living. The porous carbon is formed from food waste from toxicity reducer in wastewater to for a supercapacitor or a bio anode in a microbial fuel cell. It is oneway sustainable development and is now highly economical. Moreover, in scientific aspects, their validity in a field and lowered expenses in some cases, the benefits of their usage may vary. This paper aims to extensively review all of the research conducted for Bio-waste utilization and its conversion to porous carbon for further use in super capacitance applications

“…Mofradi prepared mesoporous carbon microspheres from corn powder by hydrothermal process. After being modified with polydopamine (PDA), the composites of microspheres-PDA were introduced in PVDF matrix in the presence of polyethylene glycol for improving the membrane performance, which was still quite complex for membrane modification [ 11 ]. Mahat et al prepared carbon quantum dots after carbonization-activation of oil palm biomass and then introduced them in polysulfone (PSF) membranes by soaking, thus resulting in enhanced water flux and antibacterial performance [ 12 ].…”

Functionalized carbon nanomaterials are considered to be an efficient modifier for ultrafiltration membranes with enhanced performance. However, most of the reported carbon nanomaterials are derived from unsustainable fossil fuels, while an extra modification is often essential before incorporating the nanomaterials in membranes, thus inevitably increasing the cost and complexity. In this work, novel functionalized biomass-based carbon nanoparticles were prepared successfully from agricultural wastes of corn stalks through simple one-step acid oxidation method. The obtained particles with the size of ~45 nm have excellent dispersibility in both aqueous and dimethyl formamide solutions with abundant oxygen-containing groups and negative potentials, which can endow the polysulfone ultrafiltration membranes with enhanced surface hydrophilicity, larger pore size, more finger-like pores, and lower surface roughness. Therefore, the separation and anti-fouling performance of membranes are improved simultaneously. Meanwhile, the addition of 0.4 wt% nanoparticles was proved to be the best condition for membrane preparation as excess modifiers may lead to particle aggregation and performance recession. It is expected that these biomass-based carbon nanoparticles are potential modifying materials for improving the separation performance and anti-fouling property of the membranes with great simplicity and renewability, which pave a new avenue for membrane modification and agricultural waste utilization.
