UV-visible Spectroscopy

UV-visible Spectroscopy UV–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent...

IR spectroscopy

IR spectroscopy Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, mostly...

Synthesis

Synthesis The Materials Synthesis and Characterization Facility includes laboratories for producing nanostructured materials and characterizing their basic structural, chemical and optical properties. The facility staff has significant experience in solution-phase...

Free Energy

Free Energy Gibbs Free Energy (G) – The energy associated with a chemical reaction that can be used to do work.  The free energy of a system is the sum of its enthalpy (H) plus the produ犀利士5mg ct of the temperature (Kelvin) and the entropy (S) of the system....

Preparation of Nylon 66

Preparation of Nylon 66 The polyamide Nylon 66 is formed by heating the reactant mixture under pressure and the process has been developed so that the molecular mass of the polymer is controlled in the range of 12,000 to 20,000 amu. Nylon-6 is prepared from the...

Tacticity

Tacticity Tacticity is the relative stereochemistry of adjacent chiral centers within a macromolecule. The practical significance of tacticity rests on the effects on the physical properties of the polymer. The regularity of the macromolecular structure influences the...
