Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Free Amino Acids

Nihon rinsho. Japanese journal of clinical medicine, 2005
Plant biomass represents a rich nutrient resource for microorganisms. This includes both structural chemical constituents that require degradation and directly accessible soluble compounds such as amino acids. The concentration of free amino acids in plant litter is dynamic and is significantly affected by degradation patterns and leaching.

Free Amino Acids in Tetrahymenidae

The Journal of Protozoology, 1963
SYNOPSIS. Free amino acids in extracts of a number of tetrahymenid genera, species and strains of Tetrahymena pyriformis were separated by a combination of paper electrophoresis at pH 1.9 and descending paper chromatography with lutidine as solvent. Ethanol extracts of ciliates cultured at temperatures of either 15°, 25° or 35°C were used.

Free Amino-acid Content of the Lymph

Nature, 1956
WE have been studying the free amino-acids of the blood and urine by quantitative paper chromatography1. This method also offered the possibility of extending our researches on lymph and of comparing the free amino-acid content of lymph and blood obtained from different areas.

Comparative Radiolability of Amino Acids of Proteins and Free Amino Acids

Radiation Research, 1964
Despite considerable work in the field of radiation chemistry of amino acids and proteins, the mechanisms of radiation damage to free amino acids and amino acids of proteins are not well understood, and more knowledge of the generalities of comparative radiolabilities of free amino acids and amino acids of proteins is needed.

Free radical-mediated oxidation of free amino acids and amino acid residues in proteins

Amino Acids, 2003
We summarize here results of studies designed to elucidate basic mechanisms of reactive oxygen (ROS)-mediated oxidation of proteins and free amino acids. These studies have shown that oxidation of proteins can lead to hydroxylation of aromatic groups and aliphatic amino acid side chains, nitration of aromatic amino acid residues, nitrosylation of ...
