Fatigue Crack Growth
The development of crack patterns is a serious problem affecting the durability of orthopedic implants and the prognosis of patients. This issue has gained considerable attention in the medical community in recent years. This literature focuses on the five primary aspects relevant to the evaluation of the surface cracking patterns, i.e., inappropriate use, design flaws, inconsistent elastic modulus, allergic reaction, poor compatibility, and anti-corrosiveness. The hope is that increased understanding will open doors to optimize fabrication for biomedical applications. The latest technological issues and potential capabilities of implants that combine absorbable materials and shape memory alloys are also discussed.

CL-20-Based Cocrystal Energetic Materials
Energetic materials (EMs) are widely used in military and civilian applications, such as weaponry, aerospace explorations and fireworks. However, both the power and safety of energetic materials are the most concern in the field of energetic materials application, but there is an essential contradiction between them: the highly energetic materials are often not safe, and, at present, the rareness of pure low-sensitive and highly energetic explosive has been found.  Due to the stringent requirements for both low-sensitivity and high-power simultaneously, the cocrystallization of explosive has attracted great interest since it can alleviate, to a certain extent, the power-safety contradiction. The new energetic cocrystals can potentially exhibit decreased sensitivity, higher performance through increased packing efficiency or oxygen balance, or improve aging due to altered bonds to specific groups on constituent molecules.

Molecular Dynamics Simulation Studies of Silicon Carbide Materials
Silicon carbide (SiC) materials are widely applied in the field of nuclear materials and semiconductor materials due to their excellent radiation resistance, thermal conductivity, oxidation resistance, and mechanical strength. The molecular dynamics (MD) simulation is an important method to study the properties, preparation, and performance of SiC materials. It has significant advantages at the atomic scale.

Anion Exchange Membranes with Inorganic Fillers
Anion exchange membrane fuel cells (AEMFC) are clean energy conversion devices that are an attractive alternative to the more common proton exchange membrane fuel cells (PEMFCs), because they present, among others, the advantage of not using noble metals like platinum as catalysts for the oxygen reduction reaction. The AEMs are the central element of many technologically relevant devices, first and foremost alkaline membrane fuel cells (FC). These fuel cells can significantly reduce the amount of noble metal catalysts for the oxygen reduction reaction (ORR) and may represent the future of FC development.

MDCs for Next-generation Optical Coatings
In Dielectric/Metal/Dielectric (DMD) type multilayer coating applications, it is very important to achieve simultaneously highly stable and durable optical properties together with accurate control over the apparent color properties of coated glass, in both reflection and transmission. In this encyclopedia entry, we report on the properties of RF magnetron co-sputtered metal-dielectric composite (MDC) material systems of interest for forward-looking applications in the areas of thin-film nanomaterials and optical coatings.

Ethiopian Anticancer Plants
This entry provides an overview on the active phytochemical constituents of twenty-seven medicinal plants that are traditionally used to manage cancer in Ethiopia. It is compiled and discusses the potential anticancer, antiproliferative, and cytotoxic agents based on the types of secondary metabolites, such as terpenoids, phenolic compounds, alkaloids, steroids, and lignans. Among the anticancer secondary metabolites reported in this review, only few have been isolated from plants that are originated and collected in Ethiopia, and the majority of compounds are reported from plants belonging to different areas of the world. Thus, based on the available bioactivity reports, extensive and more elaborate ethnopharmacology-based bioassay-guided studies have to be conducted on selected traditionally claimed Ethiopian anticancer plants, which inherited from a unique and diverse landscape, with the aim of opening a way forward to conduct anticancer drug discovery program.

2,7(3,6)-Diaryl(arylamino)-substituted Carbazoles
The carbazole is an electron-rich heterocyclic compound, whose structure can be easily modified by rather simple reactions in order to obtain 2,7(3,6)-diaryl(arylamino)-substituted carbazoles. The substituted derivatives are widely used for the formation of Organic light emitting diode (OLED) due to their good charge carrier injection and transfer characteristics, electroluminescence, thermally activated delayed fluorescence, improved thermal and morphological stability as well as their thin film forming characteristics.
