Classical methods of Chemical stability: Comparison of analyses for gunpowders [PDF]
The main ingredient of gunpowder is nitrocellulose. For slowing down the catalytical decomposition process, predominated stabilizer diphenylamine is in use for single-base gunpowder, as well as for propellants. On the other hand, the stabilizer wears out

The Impact of Glycerol on an Affibody Conformation and Its Correlation to Chemical Degradation
The addition of glycerol to protein solutions is often used to hinder the aggregation and denaturation of proteins. However, it is not a generalised practice against chemical degradation reactions.

On the Chemical Stabilities of Ionic Liquids [PDF]
Ionic liquids are novel solvents of interest as greener alternatives to conventional organic solvents aimed at facilitating sustainable chemistry. As a consequence of their unusual physical properties, reusability, and eco-friendly nature, ionic liquids have attracted the attention of organic chemists. Numerous reports have revealed that many catalysts

On the stability of microwave-fabricated SERS substrates – chemical and morphological considerations
The stability of surface-enhanced Raman spectroscopy (SERS) substrates in different organic solvents and different buffer solutions was investigated. SERS substrates were fabricated by a microwave-assisted synthesis approach and the morphological as well

Factors affecting photocatalytic degradation of Reactive Green-19 with CdO-TiO2 nanocomposite [PDF]
Cdo-TiO2 nanocomposites were synthesized by varying the molar ratio of CdO: TiO2 as 1:1, 1:2, and 2:1 using the sol-gel method. The pH value for all the CdO-TiO2 nanocomposites was controlled at two different values, pH-3 and pH-13.

Chemical control stability in the elderly [PDF]
The prevalence of central apnoea and periodic breathing is increased in the elderly. This implies that the chemical control of breathing might become less stable with ageing. To investigate this, we measured loop gain in healthy elderly individuals using proportional assist ventilation. Loop gain is an engineering term that describes the stability of a
