A powerful direct vision spectroscope

An apparatus for viewing varying thicknesses of a solution with a direct-vision spectroscope.

THE principle of altering the thickness of a solution during spectroscopic examination is of course an old one, but the writer has not seen a published account of a simple and inexpensive apparatus. That described below can easily be made in the laboratory for a few shillings, and requires little skill mechanically or in glass-blowing. It has the great advantage that 5 ml. of solution can be ex...

Characterization of Cell Phenotype Using Dynamic Vision Sensor and Impedance Spectroscope

ABSTRACT This paper reports on an improved method for characterizing single cells within a microfluidic channel, which combines the output of a Dynamic Vision Sensor camera with data from a differential impedance spectroscopy measurement. The combination of optical and impedance data allows the size, shape and position of the cells to be determined in addition to their dielectric properties. He...

Scanning Tunneling Spectroscope Use in Electrocatalysis Testing

The relationship between the electrocatalytic properties of an electrode and its ability to transfer electrons between the electrode and a metallic tip in a scanning tunneling microscope (STM) is investigated. The alkaline oxygen evolution reaction (OER) was used as a test reaction with four different metallic glasses, Ni78Si8B14, Ni70Mo20Si5B5, Ni58Co20Si10B12, and Ni25Co50Si15B10, as electrod...

A new direct-vision biopsy gastroscope.

Experience of 70 gastroscopies with direct-vision biopsy is favourable and indicates that this instrument will be of great assistance in certain difficult diagnostic problems of gastric pathology.
