Product Information

It is clear from the Table 1 that both lattices parameter ( a r and a exp) and the unit cell volume increase with the Nd 3+ contents. This increase is due to the change in ionic radius from Fe 3+ (0.67 Å) to larger ionic radius of Nd 3+ (0.99 Å). 20 Furthermore, although Nd 3+ ions have a larger ionic radius in comparison to that of Fe 3+ ions, a very thin insulating ultra-thin layer may be formed around the grains due to ions that have spread over the grain boundary. This phenomenon can cause the contraction of the spinel lattice. 21 Amende, M. et al. Dehydrogenation mechanism of liquid organic hydrogen carriers: dodecahydro- N-ethylcarbazole on Pd(111). Chem.

Nanodiamond and drug complexes (ND-X) produced from different methods are realized for drug delivery; almost all studies reported ND-X being more efficient compared to pure drug alone. However, ND of particle size less than 10 nm are found more toxic due to size and surface structure, and strongly aggregate. In vivo studies demonstrate ND accumulation in animal organs and no confirmed long-term effect studies on their release from organs are available. Standardized nanodiamond materials and drug delivery approaches are needed to advance the applications to the clinical level. Kresse, G. & Hafner, J. Ab initio molecular dynamics for liquid metals.

Ni 0.6Zn 0.4Al 0.5Fe 1.5− xNd xO 4 ferrite samples, with x = 0.00, 0.05, 0.075 and 0.1, were synthesized using the sol–gel method. The effects of Nd 3+ doping on the structural, magnetic and spectroscopic properties were investigated. XRD Rietveld refinement carried out using the FULLPROF program shows that the Ni–Zn ferrite retains its pure single phase cubic structure with Fd m space group. An increase in lattice constant and porosity happens with increasing Nd 3+ concentration. FTIR spectra present the two prominent absorption bands in the range of 400 to 600 cm −1 which are the fingerprint region of all ferrites. The change in Raman modes in the synthesized ferrite system were observed with Nd 3+ substitution. The magnetization curves show a typical transition, at the Curie temperature T C, from a low temperature ferrimagnetic state to a high temperature paramagnetic state. The saturation magnetization, coercivity and remanence magnetization are found to be decreasing with increasing the Nd 3+ concentration. To probe if our samples can be useful for high-frequency microwave applications, it is essential to have available materials with a high microwave frequency value. 19,64 The microwave frequency ( ω m) was calculated by the given equation:

Many novel drug delivery approaches utilizing nanodiamond as a platform have been demonstrated recently. This review summarizes recent developments on the nanodiamond facilitated drug delivery, from the ND-X complexes preparations to tests in the cellular and animal models. The outlook on clinical translation is discussed. Jin, R. et al. Low temperature oxidation of ethane to oxygenates by oxygen over iridium–cluster catalysts. J. Am. Chem. Soc. 141, 18921–18925 (2019).
