“…The grain size distribution of the undoped sample has a particle size of ≈1 μm, which is consistent with the literature. [53,54] When the vanadium content was increased, the size of the grains increased up to ≈2 μm, while the increasing grain size with V-content was also observed in the literature, [55] and it should be noted that the shape of grains changed from flake-like structure to spherical as well as needle-like formation by increasing V-content, as shown in Figure 3f. Figure 3g-i shows the transmission electron microscopy (TEM) image of x = 0.02, 0.04, and 0.06 powders and it is seen that the x = 0.02 and 0.04 powders have homogeneous grain formations, as observed in similar P2-type crystals.…”

The Na0.67Mn0.5−xVxFe0.43Al0.07O2 (x = 0–0.1) samples are successfully produced and their structural properties are investigated by common techniques. The highest surface area is found as 4.94 m2 g−1 for x = 0.04 V by the Brunauer–Elmet–Teller analysis. According to X‐ray photoelectron spectroscopy of x = 0.04 V‐doped sample,V4+, and V5+ ions are formed in the structure. The main phase is observed as P63/mmc symmetry with an impurity phase of V6O13 for x ≥ 0.06 . According to the CV analysis, while the redox voltage decreases for the Mn3+/Mn4+ , the intensity of the peaks of Fe2+/Fe3+ redox reaction decreases. While the best capacity value of the half cells at C/3‐rate is obtained as 171 mAh g−1 for x = 0.04, the lowest capacity fade is found for x = 0.08 . It is mentioned the V6O13 may contribute to the electrochemical process . The galvanostatic tests are investigated for the voltage windows of 3.5–1.5, 4–1.5, 4–2.5, 4–2, and 4–2.5 V and it is seen that the battery cells for 3.5–1.5 V have the best capacity fade (6%) among the others. The Na0.67Mn0.46V0.04Fe0.43Al0.07O2/ hard carbon is used for the full cells with presodiated anode and the first capacity value of the full cell is obtained as 80.2 mAh g−1 for C/2‐rate.

“…Şekil 1 üzerinde alaşımın ısıl işlemden sonra alınan faz geçişlerinin B19 / ↔B2 olduğu görülmektedir. NiTi alaşımlarında B19 / monoklinik, B2 kübik kristal yapıdadır [16][17][18]. DSC eğrileri ve Tablo 1 incelendiğinde ısıtma hızlarının artışı, alaşımın As, Af, Ap sıcaklıklarını arttırdığı, fakat Ms ve Mf sıcaklıklarını düşürdüğü görülmektedir.…”

Bu çalışmada dörtlü TiNiNbTa alaşımına farklı ısıl işlemler uygulanarak alaşımın termal parametreleri üzerine ısıl işlemlerin etkileri incelendi. Isıl işlem sıcaklıkları 700℃, 800℃ ve 900℃ seçildi. Isıl işlem yapılan alaşımların DSC eğrileri farklı ısıtma-soğutma hızına bağlı olarak alındı. Isıl işlem sıcaklığını artmasına bağlı alaşımın dönüşüm sıcaklıklarının azaldığı belirlendi. Fakat artan ısıl işlem sıcaklığı ile termal aktivasyon enerjisinin önemli derecede arttığı gözlendi. Ayrıca ısıl işlem sıcaklığının artması austenite faz pik minumununu (Ap) ve dönüşüm histeresizini (Hf) önemli derecede azalttığı gözlendi.

“…The most widely implemented bio-inert metals are surgical stainless steel (316L), cobalt-chromium (CoCr) alloys, and titanium (Ti) alloys (2). Due to their superior mechanical, fatigue, wear, and corrosion resistance, Ti-6Al-4 V alloy [78], 316L stainless-steel (SS) [79], Co-Cr-Mo [80], and nickel-titanium shape memory alloy (NiTi-SMA) [1,[81][82][83][84][85][86][87][88][89][90][91][92] are frequently chosen over other biomaterials like polymers and ceramics…”

Biomaterials are listed in advanced materials that have high biocompatibility which can easily adapt to the system in which they are implanted without leaving any adverse reactions and side effects. Due to their interesting properties such as biocompatibility, bioactivity, degradability, long-term stability, and many other important properties, all four main types of biomaterials (Bioceramics, Metallic biomaterials, Biopolymers, and Biocomposites) can be used in the medical field, either for medical treatment by implanting them in the human body, or the manufacturing of advanced medical devices. In this review, a comprehensive introduction to biomaterials has been mentioned. Also, the general properties of biomaterials are explained especially these interesting properties that are helpful to use in the medical field. And finally, the medical applications of each of the different types of biomaterials have been reviewed.
