Schniepp Group Key Equipment Items

For optical inspection of the micro-and nanoparticle samples, we use our Nikon SMZ-800 stereo zoom microscope, which is equipped with and attached CCD camera, computer control station and image analysis software (see Figure below, left side).

For high-resolution optical investigation of the micro-and nanoparticle samples, we use our Olympus iX-71 inverted optical microscope. It is equipped with many different objectives with numerical apertures magnifications in the range of 0.0625–1.3 and 5–100×, respectively. It features two lamps for transmission and reflection illumination. It is configured for many different contrasting modes, including transmission, reflection, dark field, and differential interference contrast (DIC). It is equipped with and attached CCD camera, computer control station and image analysis software (see Figure above, left).

We will used our Cole-Parmer EW-04711-40, 750-Watt ultrasonic homogenizer with temperature controller (see Figure below, right) in order to test the effect of high-powered ultrasonic waves on the removal of particles from Nb cavity surfaces.

The Laurell WS-650Bz-6NPP-Lite Spin Processor (see Figure below, left) has been used to deposit solution-suspended Nb2O5 microparticles on niobium cavity surfaces and other substrates. As well as, we use it for the AFM sample preparation of the nanoparticles and the spider silk samples for a perfect imaging.
