General description

Sulfuric acid is a strong mineral acid, that is commonly used in organic synthesis as a reagent, catalyst, and solvent. It is also useful to perform several functions, including dehydration, sulfonation, and nitration.

Application

Sulfuric acid is used:
  • As a catalyst in the esterification of acetic and palmitic acid.
  • As a solvent in the synthesis of binary technetium sulfide via the reaction of pertechnetate and hydrogen sulfide.
  • As a dehydrating agent, catalyst, and active reactant in the chemical industry.
  • To prepare silica-sulfuric acid composite, which is used as a catalyst in organic synthesis.

Low Resistivity Nanoscale Devices by Templated Electrochemistry

In many technologies, performance requirements drive device dimensions below the scale of electron mean free paths (λe). This trend has increased scientific interest and technological importance of electrical resistivities at the nanoscale.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
