A green protocol to extract chitin from crab shells using water soluble ionic liquids (ILs) is here reported. Compared to conventional multistep acid-base extraction methods, this one-pot procedure achieves pulping of recalcitrant crustacean waste shells by employing ammonium acetate, ammonium formate and hydroxylammonium acetate as water-soluble, low-cost and easy to prepare ILs. An extensive parametric analysis of the pulping process has been carried out with different ILs, different ratios, temperature and time.

The MP-reaction proceeded as an interfacial process with Mo/C or Ru/C perfectly segregated in the ionic liquid phase and the reactant(s)/products(s) dissolved in the aqueous solution. This environment proved excellent to convert quantitatively benzyl alcohols into the corresponding aldehydes with a selectivity up to 99 %, without overoxidation to carboxylic acids.

- Many kids in poorer countries, like Kenya, might have delays in their physical, emotional, and learning skills, leading to developmental problems.
- The study looked at whether certain screening tests could help identify these problems early in children living in informal settlements in Nairobi.
- Out of 509 kids tested, about 8.6% were found to be at risk, and factors like low birth weight and the mother's age seemed to influence the results.
