One method for recording neuronal activity is fluorescence microscopy, in which neurons in the brain express a fluorescent marker whose emission is modulated by the “firing” of the neuron. Our work is based on the integrated fluorescence microscope of the Schnitzer group [GBC11] which enables the acquisition of activity from large numbers of neurons in freely-behaving mice and rats. As shown in...
We describe a higher magnifying power operating microscope system to improve one method of high-quality microsurgical clipping for cerebral aneurysm in some cases. This higher magnification is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnifications (distinctiveness of 7 μm). This higher-resolution operating microscope system pro...
superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °c without any subsequent calcination. the composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using x-ray diffraction (xrd), field emission scanning electron microscope (fesem), transmission electron microscope (tem), fou...
tio2 nanorods can be used as dye-sensitized solar cells and as various sensors and photocatalysts. these nanorods are synthesized by a using thermal corrosion process in a naoh solution at 200 oc with tio2 powder as a source material. in the present work, the synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases and the synthesis of tio2 nanorods by using the sol-gel method and alkali...
(1918) view that they were attached to the cell membrane and third, that of Fuhrmann (1910) who stated that they arose from blepharoplasts. None of these opinions was accompanied by clear cut photographic evidence. The development and use of the electron microscope has made it possible to observe structures which were invisible with the light microscope. Thus Mudd and Anderson (1942) made elect...
