Influence Of Water

In recent decades, nanodiamonds (NDs) have earned increasing interest in a wide variety of research fields, thanks to their excellent mechanical, chemical, and optical properties, together with the possibility of easily tuning their surface chemistry for the desired purpose. According to the application context, it is essential to acquire an extensive understanding of their interaction with water in terms of hydrophilicity, environmental adsorption, stability in solution, and impact on electrical properties. In this paper, we report on a systematic study of the effects of reducing and oxidizing thermal processes on ND surface water adsorption. Both detonation and milled NDs were analyzed by combining different techniques. Temperature-dependent infrared spectroscopy was employed to study ND surface chemistry and water adsorption, while dynamic light scattering allowed the evaluation of their behavior in solution. The influence of water adsorption on their electrical properties was also investigated and correlated with structural and optical information obtained via Raman/photoluminescence spectroscopy. In general, higher oxygen-containing surfaces exhibited higher hydrophilicity, better stability in solution, and higher electrical conduction, although for the latter the surface graphitic contribution was also crucial. Our results provide in-depth information on the hydrophilicity of NDs in relation to their surface chemical and physical properties, by also evaluating the impacts on their aggregation and electrical conductance.

Influence Of Water

The influence of the sum of water-soluble polysaccharides (WSPSs) extracted from sedge (Acorus calamus L.) rhizomes on the state of internal organs of rats and rabbits at a long parenteral administration has been studied. The intraperitoneal WSPS introduction to rats in doses of 20, 100, and 200 mg/kg of body mass for 3 months and the intravenous WSPS introduction to rabbits in doses of 25 and 50 mg/kg of body mass for 1 months caused no pathological changes in the morphology of internal organs and systems.
