ultramicroscopes造句

• Together with the optical instrument manufacturer Zeiss, he developed the slit ultramicroscope.
• Such random motion is visible under ultramicroscopes and for bigger particles even under ordinary microscopes.
• In 1925 he was awarded the Nobel Prize in Chemistry for his research on colloids and the ultramicroscope.
• The ultramicroscope system can also be used to observe tiny nontransparent particles dispersed in a transparent solid or gel.
• So you'll never be able to use your eyes directly through some kind of ultramicroscope to see an atom.
• Zsigmondy further improved the ultramicroscope and presented the immersion ultramicroscope in 1912, allowing the observation of suspended nanoparticles in defined fluidic volumes.
• Zsigmondy further improved the ultramicroscope and presented the immersion ultramicroscope in 1912, allowing the observation of suspended nanoparticles in defined fluidic volumes.
• He used an ultramicroscope that employs a " dark field " method for seeing particles with sizes much less than light wavelength.
• In 1925, Zsigmondy received the Nobel Prize for Chemistry for his work on colloids and the methods he used, such as the ultramicroscope.
• The technique is used in conjunction with an ultramicroscope and a laser illumination unit that together allow small particles in liquid suspension to be visualized moving under Brownian motion.
• Ultramicroscopes have been used for general observation of aerosols and colloids, in studying Brownian motion, in observing ionization tracks in cloud chambers, and in studying biological ultrastructure.
• Other major types of microscopes are the electron microscope ( both the transmission electron microscope and the scanning electron microscope ), the ultramicroscope, and the various types of scanning probe microscope.
• In 1902 the ultramicroscope was developed by Richard Adolf Zsigmondy ( 1865 1929 ) and Henry Siedentopf, working for Carl Zeiss AG . In 1925, Zsigmondy received the Nobel Prize for Chemistry also for this work.
• It is particularly applicable to colloidal mixtures and fine suspensions; for example, the Tyndall effect is used in nephelometers to determine the size and density of particles in aerosols and other colloidal matter ( see ultramicroscope and turbidimeter ).
• The " " ultra " " in " ultramicroscope " refers to the ability to see objects whose diameter is shorter than the wavelength of visible light, on the model of the " " ultra " " in ultraviolet.
• In 1902 the ultramicroscope was developed by Richard Adolf Zsigmondy ( 1865 1929 ) and Henry Siedentopf ( 1872 1940 ), working for Carl Zeiss AG . Applying bright sunlight for illumination they were able to determine the size of 4 nm small nanoparticles in cranberry glass.
• The book ends with the image of a biologist, much like Haldane himself, in a laboratory : " just a poor little scrubby underpaid man groping blindly amid the mazes of the ultramicroscope . . . conscious of his ghastly mission and proud of it ."
