Electrochemical workstation (BIOLOGIC - VSP-300)

IM — 2023-05-12T14:48:54Z

Theory
An electrochemical workstation is capable of carrying out numerous electrochemical experiments including constant potential and constant current, concurrently. It is used to regulate and monitor several electrochemical reaction parameters, such as potential, current, charge transfer, etc. It typically includes a potentiometer, auxiliary electrode, working electrode, reference electrode, computer, and data collecting software, among other components.

Tabletop Scanning Electron Microscope (HITACHI TM4000Plus II)

IM — 2023-05-04T13:03:00Z

The Hitachi TM4000Plus II is a benchtop scanning electron microscope (SEM) that allows for the observation of hydrated samples without the need for prior metallization. This technique brings the advantage to work with non-conductive samples in low vacuum conditions. Environmental scanning microscopy is based on the emission of a thermionic electron beam from the tungsten filament, where secondary electrons and backscattered electrons give information about the topography and composition of (…)

Raman spectrometer (RENISHAW)

IM — 2023-05-04T12:56:28Z

Theory
The Raman spectroscopy is a vibrational spectroscopy technique similar & complementary to the infrared spectroscopy (FT-IR). It is based on the inelastic scattering of laser photons. This feature is known as Raman scattering. The energy of different vibrational modes (then the wavenumbers) is determined by the simple comparison between scattered and incoming photons energy. Thus, Raman spectroscopy provide both chemical and structural information.

Impact Tester

IM — 2019-04-09T12:03:43Z

The Impact Tester is a simple to use gauge ideal for evaluating the resistance of a coating to impact (elongation, cracking or peeling).
There are two impact test methods: either a weight with a hemispherical punch attached falls on a coated metal sheet or a weight falls on to a hemispherical punch which is resting on the coated metal sheet.
The test specimen is fixed into position by the quick release clamp. The weight is lifted to the predetermined height and can be set by the adjustable (…)
