Such combination of time, temperature, pressure, structural and chemical resolution has made ESTEM a versatile instrument that may be considered as a nano-scale laboratory for in situ synthesis and characterization. This chapter starts with a brief description of various approaches for making in situ...

8). This could be expected because of structural disorder at the surface, leading to additional distributions of chemical shift and/or quadrupolar parameters. The 1H–13C HETCOR spectrum of C–HAp is presented in Fig. 4a. It is clearly demonstrated that even in the case of 13C at natural ...

The chemical composition of INCONEL alloy 725 is given in Table 1. High levels of nickel and chromium provide corrosion resistance in reducing and oxidizing environments. The substantial molybdenum content enhances resistance to reducing media and provides a high degree of resistance to pitting and ...
There is no chemical action and metabolism within or on the body of patients after implantation. Through querying the FDA classification database using plate and screw as keywords, the results showed that this product can be classified as Class II: Plate, Fixation, Bone (CFR 888.3030) or Class...
However, in addition to its very low inhibitory activity on human aspartic proteases, the adverse effects of Ritonavir make it necessary to develop new CYP3A4 inhibitors with improved pharmacochemical properties. Combining C5-aryltetrazole with an adipic acid (AA) analogue is an interesting approach...
Such spectroscopic studies should contribute to new methods for the chemical analysis of AFR. Conclusion We demonstrated in vitro DNP-MR imagings at the low ESR irradiation frequency ranging from 515–530 MHz for the PQQ), AFR and produced in revealed the tshime rileadroitxiecsyacnlindgthree...
