| The magnetic susceptibility of a paramagnetic material is inversely proportional to absolute temperature. |
|
| In paramagnetic materials, permanent magnetic moments arise from the intrinsic angular momentum of individual electrons. |
|
| The presence of water molecules surrounding a paramagnetic metal ion can be detected via magnetic interactions with the water protons. |
|
| The photochemistry of ninhydrin in benzene and water was studied by laser flash photolysis and electron paramagnetic resonance. |
|
| The MS depends on factors such as the concentrations of ferrimagnetic and paramagnetic minerals and the magnetic grain size. |
|
| Substances for which the magnetic susceptibility is positive are classed as paramagnetic. |
|
| The strength of the susceptibility is comparable to that of paramagnetic materials. |
|
| Recently, high-resolution pulsed EPR techniques have been developed that can reveal detailed information on the environment of the paramagnetic transition metals. |
|
| For the first time a procedure was used that is called electron paramagnetic resonance. |
|
| The PMA 50 EEX utilises the paramagnetic principle of operation to measure oxygen concentrations. |
|
| The signal is variable in T2, due to the appearance over time of haemoglobin breakdown products with a paramagnetic effect. |
|
| Electron paramagnetic resonance is a spectroscopic technique similar to nuclear magnetic resonance except that microwave radiation is employed instead of radio frequencies. |
|
| The principle of EPR oximetry is based on the broadening effect of molecular oxygen on the EPR spectra of paramagnetic substances via Heisenberg spin exchange. |
|
| Electron paramagnetic resonance spectra were recorded on a Varian E-3 X-band spectrometer at 77 K and at room temperature. |
|
| Like diamagnetism, paramagnetism is weak and exists only in the presence of an applied field, but since the effect enhances the applied field, the sign of the paramagnetic susceptibility is always positive. |
|
| Goethite is known to exhibit a remanent paramagnetic signal due to defects that accounts for these observations. |
|
| At high temperatures the material is paramagnetic, but below a certain characteristic temperature the dipoles are aligned in an ordered and antiparallel manner. |
|
| An agent for modifying relaxation times in NMR diagnosis, comprising a polysaccharide having chemically linked to it an organic complexant to which is complexed a paramagnetic metal ion. |
|
| One possible method currently being assessed uses injection of super paramagnetic contrast products, along the same lines as for detection and characterisation of secondary hepatic lesions. |
|
| Most elements and some compounds are paramagnetic. |
|
|
|
| Materials for which this can be applied are much more limited since the material needs to both have an unpaired spin and be paramagnetic. |
|
| They remove very fine ferrous particles, locked particles and even strongly paramagnetic particles. |
|
| A magnetic refrigerator uses the magnetocaloric effect that appears when a paramagnetic material is magnetized and demagnetized. |
|
| The metal form is slightly paramagnetic, meaning its magnetic dipoles align with external magnetic fields, but will assume random orientations once the field is removed. |
|
| A magnetocaloric material exhibits a strong magnetocaloric effect near the Curie temperature, when the phase changes from paramagnetic to ferromagnetic. |
|
| In addition, the company has obtained worldwide exclusive license for an emerging melanoma diagnostic and prevention technology utilizing Electron Paramagnetic Resonance. |
