“…Raw bones were collected from a local market and cleaned with cold water followed by hot water at 90 °C for one hour to get rid of meat from the bones. Bones were treated chemically to separate organic soft collagen to extract inorganic particles following the procedure developed by Owuor et al 23 Polyvinyl alcohol (PVA) (Sigma-Aldrich) with a molecular weight of 130,000 and 99+% hydrolyzed was used as a rheology modifier. Polyethylene glycol (Sigma-Aldrich) with an average molecular weight of 400 was used as a dispersant.…”

Direct ink writing (DIW) additive manufacturing is a versatile 3D printing technique for a broad range of materials. DIW can print a variety of materials provided that the ink is well-engineered with appropriate rheological properties. DIW could be an ideal technique in tissue engineering to repair and regenerate deformed or missing organs or tissues, for example, bone and tooth fracture that is a common problem that needs surgeon attention. A critical criterion in tissue engineering is that inserts must be compatible with their surrounding environment. Chemically produced calcium-rich materials are dominant in this application, especially for bone-related applications. These materials may be toxic leading to a rejection by the body that may need secondary surgery to repair. On the other hand, there is an abundance of biowaste building blocks that can be used for grafting with little adverse effect on the body. In this work, we report a bioderived ink made entirely of calcium derived from waste animal bones using a benign process. Calcium nanoparticles are extracted from the bones and the ink prepared by mixing with different biocompatible binders. The ink is used to print scaffolds with controlled porosity that allows better growth of cells. DIW printed parts show better mechanical properties and biocompatibility that are important for the grafting application. Degradation tests and a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay study were done to examine the biocompatibility of the extracted materials. In addition, discrete element modeling and computational fluid dynamics numerical methods are used in Rocky and Ansys software programs. This work shows that biowaste materials if well-engineered can be a never-ending source of raw materials for advanced application in orthopedic grafting.

Supercapacitors have attracted considerable attention as promising power sources for applications that need energy pulses during the short periods of time. The separator is one of the most important parts of a supercapacitor and plays a critical role in avoiding internal electronic short circuits and constructing safe and highperformance supercapacitors. Currently, commercial cellulose-based separators are limited by the low mechanical strength or high self-discharge rate, while commercial polyolefin-based separators suffer from the poor thermal stability. Recently, tremendous efforts have been devoted to developing advanced separators with high performance. To better understand the contributions of the separators on improving the electrochemical performance and safety of supercapacitors, we discussed the fundamental requirements for ideal separators and the effects of raw materials, preparation strategies, and properties of separators on the electrochemical performance of supercapacitors. Outlooks and future directions for the rational design of advanced separators are also provided.

A porous polylactic acid (PLA) film was investigated as a separator for supercapacitors (SCs) and compared with commercial separators, for example, NKK-MPF30AC and Celgard 2400. The porous PLA film was fabricated via a facile phase inversion method, and the cross-sectional scanning electron microscope images of the PLA separator film exhibited highly porous interconnected morphology for ion diffusion. The surface modification of separators was performed by radio frequency (RF) air plasma to improve wettability. The plasma modification enhanced the water uptake and swelling properties of the separators and decreased the water contact angles of PLA and Celgard 2400 films. The mechanical and dielectric properties of separators were also studied. The ionic conductivities of RF-PLA in 1 M H2SO4 and 1 M Na2SO4 were found to be 1.1 x 10 -1 S/cm and 0.6 X 10 -2 S/cm at room temperature, respectively. The electrochemical impedance spectroscopy of the RF-PLA SCs showed the lowest solution resistance and internal resistance.
