How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

A new family of neutral ruthenium(II) arene complexes of the type [Ru(η6-arene)X(κ2- O, N-L)] (η6-arene = p-cym, bz; X = Cl-, SCN-; HL1 = 2-(2'-hydroxyphenyl)benzimidazole, HL2 = 2-(2'-hydroxyphenyl)benzothiazole) has been synthesized and characterized. The cytotoxic activity of the Ru(II) complexes was evaluated in several tumor cell lines (A549,...
The interaction of RNA and DNA with two aluminum-containing complexes has been studied at 25°C by 1H-NMR, UV and CD spectroscopies, viscosity measurements and DFT simulations. The complex identified at pH = 7, Al13Cacx, can interact with the polynucleotides by external binding. Even though the affinity degree of the aluminum complex with RNA is ess...
Over the last years, focused interest in aluminum has been heightened by recent studies regarding its health effects. The possible relation with chronic diseases makes it convenient to address more in depth the reactivity of aluminum with biologically relevant molecules. The present work investigates the interaction of aluminum ion with two synthet...

Aluminium ion is believed to cause a number of neurological and skeletal disorders in human body. The study of the biological processes and molecular mechanisms that underlie these pathological disorders is rendered a difficult task due to the wide variety of complex species that result from hydrolysis of Al3+ion. In addition, this ion displays a p...

Anticancer activity and mechanistic insights of new Ru(II) half-sandwich complexes with hydroxiphenylbenzoazole ligands
I would ask about ICP-OES system, I am using it for metal detection in mineralized aliquots of soil and waste samples.
I am using an old method developed in my current lab, but I would like to improve it to obtain a better signal to noise ratio and lower LOD. So my question is:
Which are the variables to take into account for the method optimization?
I have considered yet:
- the wavelengths (I will perform proofs at different recommended WLs for every metal)
- the radial and axial mode (I will use axial because I saw that the LODs are lower in such a condition)
Is there any other parameter which I would consider? For example: is the time of acquisition important in the increase of the S/N ratio?
Thanks a lot to everyone who can give me some advice about that.
Hi all, I would like to know if anyone can give me some information about the signal stability of ICP-OES for metal detection. I found some trouble with my equipment because it takes lot of Time to stabilize the signal, in particular for Pb detection, and I waste a lot of argon. What It could bè the reason?
