Effects of magnetic field on the morphology of nickel nanocrystals prepared by gamma-irradiation in aqueous solutions

An extra magnetic field was introduced when nickel nanocrystals were prepared by gamma-irradiation technique. Results of transmission electron microscope (TEM) images showed that the extra magnetic field significantly changed nanocrystals morphology. Possible reasons that resulted in the morphology change were discussed from the angle of the interaction between nickel atoms and the magnetic field.

Movies Show Quick Magnetic Flips

A region of magnetic material flips direction quicker when an extra magnetic field is present, according to new high speed movies. The experiments show how the read and write operations in disk drives work at a microscopic level.

THERMAL STABILITY OF HAEMOGLOBIN SOLUTIONS UNDER DC AND AC MAGNETIC FIELD AND UV AND IR RADIATION

The influence of electromagnetic field in wide range of frequency (extra low frequency magnetic field, monochromatic laser light 840 nm, ultraviolet light) and static magnetic field on the stability of aqueous and NaCl 0.9% haemoglobin solutions was studied using differential scanning calorimetry (DSC) method. Three steps of denaturation process can be derived from experimental data. The shifts of transition temperatures are more marked for NaCl 0.9% than for aqueous solutions. The results suggest that static magnetic field is effective in protecting protein, while ultraviolet radiation destabilises haemoglobin. The laser light and alternating magnetic field have a little effect on the thermal stability of haemoglobin.

The magnetic field effect affecting on the metallic chemical components of egg shell as demonstrated for breeding chicken

The chickens were raised under fixation of the permanent magnet (80 mT) and the effect of extra magnetic field, which affects on the content of the several inorganic chemical elements of egg shell, was investigated by X-ray fluorescence spectroscopy. From 3 days after fixing the magnet, the relative concentration of Ca begun to increase. After 10 days, the relative contents of Ca were decreased, while conversely the contents of K were increased. Though there was a linear relationship between Ca content and P content in inner layer of chicken egg shell, the relationship was greatly hindered by applying the static magnetic field. The experimental result suggests that both Ca and K ion transport can be perturbed by addition of extra magnetic field in the incubation processes of chicken egg, and that Ca, P and K ions play the important role in egg shell formation.

A bi-symmetric square wave Zeeman modulator for nuclear quadrupole resonance

A simple circuit has been designed to generate a bi-symmetric square wave Zeeman modulation for the detection of nuclear quadrupole resonance. The square waveform not only provides an optimum result among bi-symmetric modulation waveforms, but also allows the observation of the Zeeman perturbed NQR powder pattern without the need for an extra external magnetic field.
