“…Recently amounts of studies on magnesium-based metals are conducted for their potential to be used as biodegradable implants due to their biocompatibility combined with good physical and mechanical properties25262728. Importantly, it was found that magnesium could influence bone tissue growth positively, which could improve the bone healing and reconstruction2930.…”

Titanium and its alloys with various porous structures are one of the most important metals used in orthopaedic implants due to favourable properties as replacement for hard tissues. However, surface modification is critical to improve the osteointegration of titanium and its alloys. In this study, a bioactive magnesium coating was successfully fabricated on porous Ti6Al4V by means of arc ion plating, which was proved with fine grain size and high film/substrate adhesion. The surface composition and morphology were characterized by X-ray diffraction and SEM equipped with energy dispersive spectroscopy. Furthermore, the in vitro study of cytotoxicity and proliferation of MC3T3-E1 cells showed that magnesium coated porous Ti6Al4V had suitable degradation and biocompatibility. Moreover, the in vivo studies including fluorescent labelling, micro-computed tomography analysis scan and Van-Gieson staining of histological sections indicated that magnesium coated porous Ti6Al4V could significantly promote bone regeneration in rabbit femoral condylar defects after implantation for 4 and 8 weeks, and has better osteogenesis and osteointegration than the bare porous Ti6Al4V. Therefore, it is expected that this bioactive magnesium coating on porous Ti6Al4V scaffolds with improved osteointegration and osteogenesis functions can be used for orthopedic applications.

“…Additionally, at low HNO 3 concentration levels (1 mol L −1 ), the extraction efficiencies were within 99 to 108%, which makes the developed method to be greener as compared to 3 mol L −1 HNO 3 . It is worth noting that, analyte recoveries greater than 100% have been observed for REEs elements ranging between 94-110% [27], 91-117% [28], 86-119% [28], and 92-112% [29]. Thus, 1 mol L −1 HNO 3 concentration was selected as the optimum level to guarantee the total release of the remaining REEs binding to the white solid residues of the coal.…”

The world during the COVID-19 pandemic has led to extensive use of virtual activities by means of electronic devices, which are made up of rare earth elements (REEs). This means that quantitative knowledge of REEs in various resources is crucial for the development of effective recovery methods. Therefore, this report describes a simple microwave assisted ashing followed by ultrasound-assisted extraction (MAA-UAE) for quantitative determination of REEs in coal samples using inductively coupled plasma-optical emission spectroscopy (ICP-OES). Firstly, coal samples were ashed at 55 °C for 4.5 h to form white ashes, which were then treated with dilute HNO3 acid under ultrasonication to enhance the extraction of REEs. The quantitative recoveries (86–120%) of REEs were obtained when 1 mol L−1, 0.1 g, 40 °C, 20 min, and high frequency were applied for [HNO3], sample mass, ultrasonic bath temperature, extraction time, and ultrasonic bath frequency, respectively. The method detection limits of the proposed MAA-UAE method were between 0.0075 and 0.59 µg g−1 with satisfactory precision (<5%). The concentration levels of REEs in South African coals ranged from 1.4 to 105 µg g−1, suggesting that this coal can be a resource for REEs.

“…135,136 Research suggests that Y element shows solid solution effect on magnesium alloys due to its high solubility in magnesium. 137 Nd in the WE43 magnesium alloy elevates the mechanical properties mainly by grain boundary strengthening, due to the formation of the intermetallic phase in the grain boundary. 138 Zhang et al 58 indicated that the Y element could refine the microstructure of Mg-Zn alloy to some extent and the Zn/Y ratio influences the formation of secondary phases (the I-phase exhibit better strengthening effect than the W-phase) in Mg-Zn-Y alloys significantly.…”

Magnesium-based alloys exhibit biodegradable, biocompatible and excellent mechanical properties which enable them to serve as ideal candidate biomedical materials. In particular, their biodegradable ability helps patients to avoid a second surgery. The corrosion rate, however, is too rapid to sustain the healing process. Alloying is an effective method to slow down the corrosion rate. However, currently magnesium alloys used as biomaterials are mostly commercial alloys without considering cytotoxicity from the perspective of biosafety. This article comprehensively reviews the status of various existing and newly developed degradable magnesium-based alloys specially designed for biomedical application. The effects of critical alloying elements, compositions, heat treatment and processing technology on the microstructure, mechanical properties and corrosion resistance of magnesium alloys are discussed in detail. This article covers Mg–Ca based, Mg–Zn based, Mg–Sr based, Mg–RE based and Mg–Cu-based alloy systems. The novel methods of fabricating Mg-based biomaterials and surface treatment on Mg based alloys for potential biomedical applications are summarized.
