Metallic biomaterials are used in medical devices in humans more than any other family of materials. The corrosion resistance of an implant material affects its functionality and durability and is a prime factor governing biocompatibility. The fundamental paradigm of metallic biomaterials, except biodegradable metals, has been “the more corrosion resistant, the more biocompatible.&rdquo
The EDS analysis of point 1 shows a high content of Ta followed by C, Cl, Na, and O, as detailed in Table 4. The high levels of C might be related to the deposition of the carbides …

The individual DNDs are of ~4nm in size, and have been studied with CL, PL, Raman and IR spectroscopies, AFM and HR-TEM as well as electrically measured through the use of impedance spectroscopy. When the results from these differing techniques are coined it is apparent that the B-DNDs studied here do indeed support substitutional boron species and hence will be acting as …

Tungsten, or wolfram, is a chemical element with the syol W and atomic nuer 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tungsten which means "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively coined with other elements in chemical compounds rather than alone.
Changes in the white line are evident (Fig. 4.16a), and in comparing the spectra to those of reference compounds, reduction was found to proceed by way of Fe 2 O 3 to Fe 3 O 4 to FeO to Fe carbides. Simultaneous EXAFS spectra were recorded (Fig. 4.16b).
