Similarly, cellulose content was determined by subtracting ADL from ADF.…”

Exploration of solvent casting for designing engineered microstructures for biomedical and functional applications

Tissue engineering (TE) (also referred to as regenerative medicine) has emerged as a pathway for designing biomedical implants. [1][2][3][4][5][6][7][8][9][10][11][12] The underlying philosophy of this approach is to create a designed matrix (3D scaffolds) which can provide temporary healing framework for the diseased and damaged tissue. Based on the type of the tissue generation, TE can be classified into soft (for example, skin, blood vessel etc) and hard tissue (for example, bone). 1 Brien et al. 2 have listed important conditions for scaffolds as: (a) biocompatibility: scaffolds should not have adverse reaction to cells, show negligible immune response, and facilitate blood vessel development. 2 In addition, Bose et al. 3 have also mentioned that the scaffold should show, (a) osteoconductivity (bone cells should be

“…Due to the hydrophobic properties of zein proteins, corn‐DDGS has been used as a multifunctional filler in synthetic resin bonded wood particleboards to improve their physical and mechanical properties (Sundquist & Bajwa, 2016). In addition, Liaw et al (2019) reported that particleboards from several formulations based on various concentrations of acid and alkali treatments were hot‐pressed and concluded that the acetic acid‐treated particleboards with higher DDGS concentrations showed better water resistance. These applied explorations suggest that DDGS proteins could be a potential alternative to petroleum‐based resins.…”

Dried distillers' grains with solubles (DDGS) are the main byproduct from bioethanol production and are commonly used as livestock feed. This work aims to provide an overview of animal feed value (protein and amino acid profiles and protein fractionation approaches) and potential non‐food uses of DDGS proteins, particularly those from corn, sorghum, and wheat. Crude protein and amino acids (essential and nonessential) composition vary among different DDGS due to the variation in chemical composition of parent feedstock and processing condition. Extraction or fractionation approaches such as physical/mechanical (sieving and winnowing), chemical (ethanol, acid, and alkaline), and enzymatic (protease) treatments have been explored to isolate specific proteins of corn (zein), sorghum (kafirin), and wheat (gluten protein) from respective DDGS. In addition, valorization of DDGS proteins for biomaterials (biodegradable films and bioadhesives) was evaluated. Due to the heterogeneous nature of DDGS, multi‐stream processes with economic and environmental benefits should be taken into consideration before the commercialization of DDGS proteins. This review will benefit future research and development activities on value‐added and more specific utilizations of DDGS.

We report the synthesis and characterization of engineered PEEK‐based composites by using biochar (DDGS500—pyrolyzed Distiller's dried grains with soluble (DDGS)), metal (Mo), and PEEK‐ceramic (Xonotlite) as reinforcements. A systematic study was done to understand the effect of these additives on functional and mechanical properties. Initially, these composites were synthesized by hot pressing. Microstructure analysis of reinforcement powders by scanning electron microscopy (SEM). Detailed microstructure study of the composites showed that DDGS500 powder particulates were well dispersed within the PEEK matrix after the addition of 5 vol%. However, at higher concentration of 10 and 20 vol%, the particles segregated at the phase boundaries and PEEK rich cores were observed in the microstructure. Mo and Xonotlite particles were segregated at the phase boundaries even at 5 vol% concentration, which was more prominent at higher concentrations of 10 and 20 vol% reinforcements. Differential scanning calorimetry (DSC) showed lowering in melting point (Tm) and crystallization temperature (Tc) and increase in crystallization in all the composites. The addition of DDGS500 and Mo enhanced the plasticity and Ultimate Compressive Strength (UCS) (5 vol% additions of DDGS500 and Mo enhanced the UCS by 12.6% and 32.2%, respectively) of the composites whereas Xonotlite additions increased brittleness of the composites. The addition of DDGS500, PEEK‐Mo, and PEEK‐Xonotlite particulates lowered the wear rate until 10 vol% by several orders of magnitude and stabilized the friction coefficient (μ) versus distance profile. However, significant increase in wear rate at 20 vol% of Xonotlite was observed due to third body abrasion. All the composites showed hydrophobic behavior except PEEK‐20 vol% Xonotlite, which showed hydrophilic behavior with a decrease in contact angle as a function of time, which shows that Xonotlite can be a promising additive for increasing hydrophilicity of PEEK‐based composites for biomedical applications.
