1 زیست شناسی:: رزونانس مغناطیسی هسته‌ای (NMR)

• NMR, MRI, fMRI X-ray machines are used for the detection of abnormalities, NMR, now called magnetic resonance imaging (MRI) by medical practitioners helps in the detection of tumor growth, which in turn can be treated by radiation from radioactive sources. Interactions of AMPs with lipid membranes, using different techniques such as differential scanning calorimetry (DSC), 31 P-nuclear magnetic resonance (NMR) spectroscopy, X-ray diffraction, etc. Careful mapping of the above-mentioned lipid phase diagrams by X-ray diffraction and nuclear magnetic resonance spectroscopy has revealed that this lipid in fact undergoes HII-to-Lα-HII transitions with progres- sive hydration, which has been called a 'reentrant' transition [16, 24]. Solid-state nuclear magnetic resonance (NMR) spectroscopy and other biophysical techniques indi- cate that peptide antibiotics strongly interact with lipid membranes.

2 مهندسی شیمی:: تشدید مغناطیسی هسته‌ای

Nuclear magnetic resonance (NMR) 18 FTIR, Raman spectroscopy, XPS, NMR and EPR can be used to study the properties of MOF separation membrane surfaces, including the functional groups or other substances on the surface of the membrane, the contamination of the membrane surface, and whether the MOF-based composite membrane is successfully synthesized. More importantly, NMR, EPR and HRNPD can be used to study the molecular dynamics and synthesis mechanism of the MOF membranes. FTIR, XRD, XPS, XAS, NMR, EPR and HRNPD can be used to accurately characterize the crystal structure of MOF particles, and the characterization results of MOF particles after defect engineering can be obtained as well. Among them, XAS and NMR can obtain MOF particle information at the atomic level.

5 متالوژی:: رزونانس مغناطیسی هسته‌ای (NMR)

To understand this structural change, studies by solid-state nuclear magnetic reso- nance (NMR) were carried out (Leonova et al. 2008). The 31P solid-state NMR results provided evidence that the presence of CaO and P2O5 in 85SiO2-10CaO-5P2O5 MBG leads to the formation of amorphous calcium phosphate (ACP) clusters that accumu- late onto the material surface (Figure 1.16). On the contrary, in the absence of phosphorus, such as in 90SiO2-10CaO MBG, the total calcium content provoked a disruption in the silica network, as confirmed by 29Si-solid state NMR (Gunawidjaja et al. 2012). 31P NMR FIGURE 1.16 TEM images and their corresponding of MBGs in the absence or presence of phosphorus. 31P solid-state NMR of P-containing MBG showing the formation of ACP clusters is also displayed.
