Microchemical analysis of otolith (calcified 'ear stones' used for balance and orientation) of fishes is an important tool for studying their environmental history and management. However, the spatial resolution achieved is often too coarse to examine short-term events occurring in

Uncontrolled reactions in biological media are a main obstacle for clinical translation of V-based anti-diabetic or anti-cancer pro-drugs. We investigated the use of controlled-release pharmaceutical formulations to ameliorate this issue with a series of V(V) and (IV) complexes of anionic

The fate of NO(x) (=NO + NO(2)) is important to understand because NO(x) is a significant player in air quality determination through its role in O(3) formation. Here we show that renoxification of the urban atmosphere may occur through the

Certain molecular mechanisms of Cd tolerance and accumulation have been identified in the model species Arabidopsis halleri, while intraspecific variability of these traits and the mechanisms of shoot detoxification were little addressed. The Cd tolerance and accumulation of metallicolous and

What is the difference between Product 258121 and the 90% red, fuming nitric acid (Product No. 309079)?
1 answer-
Product 258121 is a colorless to yellow solution of nitric acid that has at least 90% as HNO3 and less than 0.1% dissolved oxides. Product 309079 appears red because it can contain 5-10% of dissolved nitrogen oxide (as N2O3 ).
